1Version 2.2.0 (9 May 2021)
2
3  * general changes:
4    - Fixed compiler error in Pool.h.
5    - Require C++14 compiler support.
6    - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7      for checking in configure for C++14 support (as mandatory
8      requirement) and automatically adds compiler argument if required
9      (e.g. -std=C++14).
10    - RTMath: Implemented floating point comparison methods
11      fEqual32(float,float) and fEqual64(double,double) which take the
12      expected floating point tolerances into account.
13    - Added public API C++ class "LFO", which is a cluster class encapsulating
14      all the sampler's LFO implementations to be used by 3rd party applications
15      (e.g. by Gigedit).
16    - Added int math square LFO implementation.
17    - Added int math saw LFO implementation.
18    - Added numeric complex nr sine LFO implementation.
19    - Marked class LFOTriangleDiHarmonic as deprecated
20      (will be removed in future).
21    - Added LFOAll.h which includes all LFO implementation's header files.
22    - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23      LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24      SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25      SquareLFO -> LFOSquarePulse and separated the latter to its own header
26      file).
27    - Renamed type LFOSigned -> LFOTriangleSigned.
28    - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29    - Using now cubic interpolation as resampling algorithm by default; and
30      linear interpolation is deprecated now.
31    - Event:Init(): memset() entire Event::Param union to zero instead of trying
32      to do that for its individual members; the latter became error prone due
33      to the union's growing complexity meanwhile.
34    - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35      *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36      methods and marked the old ones as deprecated; and likewise added new
37      *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38      methods and marked those old ones deprecated as well.
39    - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40      resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41    - Implemented support for compressed RPN/NRPN message sequences (that is to
42      allow processing MIDI data entry messages without always having to be
43      preceded strictly by RPN/NRPN parameter selection messages on each value
44      change).
45    - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46      decrement).
47    - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48      MSB=127 and LSB=127) and which is disabling subsequent data
49      entry/increment/decrement CC messages.
50    - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51      instrument editor.
52    - Fixed playing noise at the end of a disk stream under certain conditions.
53    - Fixed potential crash with high pitch at end of RAM playback.
54    - Added configure checks whether C++ compiler supports so called
55      'designated initializers'.
56    - Added global backtraceAsString() function for debugging purposes
57      (POSIX systems only, no Windows implementation yet).
58    - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59      nameOfCaller() and setNameOfCaller().
60    - configure: Always check for availability of pthread_testcancel() and use
61      it if so (previously it was only used if explicitly enabled by configure
62      option).
63    - Thread class: raise compiler warning if pthread_testcancel() is not
64      available, because it can lead to deadlocks.
65    - Mutex class: Implemented optional bug detection and deadlock debugging
66      features.
67    - Ref<> class is now thread safe (as lock-free and wait-free
68      implementation).
69    - Fixed compilation error with Bison >= 3.6.0.
70    - Fixed rare crash when switching between instruments that had instrument
71      scripts loaded.
72    - Allow EffectChain::InsertEffect() as alternative to
73      EffectChain::AppendEffect() (i.e. with index equal to current chain size).
74    - ConstCapacityArray class: Fixed bug in remove() method.
75    - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
76      real-time instrument script was loaded.
77
78  * Real-time instrument scripts:
79    - Added method ScriptVM::setExitResultEnabled() which allows to
80      explicitly enable the built-in exit() function to optionally accept
81      one function argument; the value of the passed exit() function
82      argument will then become available by calling
83      VMExecContext::exitResult() after script execution.
84    - 64 bit support for NKSP integer scripts variables (declare $foo).
85    - Variable names, function names and preprocessor condition names must start
86      with a regular character (a-z or A-Z); starting them with a digit or
87      underscore is not allowed.
88    - NKSP parser fix: equal comparison operator "=" and not equal comparison
89      operator "#" must only accept integer operands.
90    - NKSP language: Implemented support for standard units like Hertz, seconds,
91      Bel including support for metric unit prefixes; so one can now e.g.
92      conveniently use numbers in scripts like "5us" meaning "5 microseconds",
93      or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
94      "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
95    - NKSP language: Introduced "final" operator "!" which is specifically
96      intended for synthesis parameter values to denote that the synthesis
97      parameter value is intended to be the "final" value for that synthesis
98      parameter that should explicitly be used by the engine and thus causing
99      the sampler engine to ignore all other modulation sources for the same
100      synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
101      variable or formula with this new "!" operator the expression is marked as
102      being "final".
103    - NKSP script editor API: Added support for detecting standard unit tokens
104      and their potential metric prefix token.
105    - NKSP language: Added support for NKSP real number literals and
106      arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
107    - NKSP language: Added support for NKSP real number (floating point) script
108      variables (declare ~foo).
109    - NKSP language: Added support for NKSP real number (floating point) array
110      script variables (declare ?foo[]).
111    - Built-in script function "message()" accepts now real number argument as
112      well.
113    - Added built-in script function "real_to_int()" and its short hand form
114      "int()" for casting from real number to integer in NKSP scripts.
115    - Added built-in script function "int_to_real()" and its short hand form
116      "real()" for casting from integer to real number in NKSP scripts.
117    - Allow built-in exit() function to potentially accept real number type
118      argument as well.
119    - Built-in script functions may have a different return type depending on
120      the arguments passed to the function.
121    - Built-in script function "abs()" optionally accepts and returns real
122      number.
123    - Built-in script functions "min()" and "max()" optionally accept real
124      number arguments and return real number as result in that case.
125    - NKSP VM API: Allow units and 'final'ness to be returned as result from
126      built-in functions (added methods VMFunction::returnUnitType() and
127      VMFunction::returnsFinal() for that purpose which must be implemented by
128      built-in function implementations).
129    - NKSP language: Allow metric unit prefixes of numeric scalar and array
130      variables to be changed freely at runtime (unlike unit types like Hz etc.
131      which are still sticky, parse-time features of variables which cannot be
132      changed at runtime for the intentional sake of determinism).
133    - NKSP language: 'final' values are prohibited for array variables for now
134      (attempt causes a parsers error).
135    - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
136      conditions of runtime control structures like if(), while(), select()
137      (attempt causes a parser error).
138    - NKSP VM API: Allow built-in functions to perform their own, individual
139      parse time checks of arguments going to be passed to the function at
140      runtime (added method VMFunction::checkArgs() for that purpose).
141    - NKSP language: raise parser warning if only one operand of binary
142      operators (like logical 'or' comparison) contain a 'final' value (because
143      it would always yield in a 'final' result in such cases).
144    - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
145      different metric unit prefixes, which will behave as expected (e.g.
146      result of expression '1000us < 2ms' is true).
147    - NKSP language: Allow adding values with different metric unit prefixes
148      (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
149    - NKSP language: Allow subtracting values with different metric unit
150      prefixes (e.g. result of expression '1ms - 20us' is '980us').
151    - NKSP language: Allow multiplying with any metric unit prefixes
152      (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
153      with unit types on both sides (e.g. '2s * 2s') is still prohibited since
154      we don't have any considerable practical use for a term like '4s^2'
155      (hence any attempt multiplying two unit types still causes parser error).
156    - NKSP language: Allow dividing by any metric unit prefixes and allow
157      division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
158      yields in unit free result '8'). So this is now a way to cast units away
159      e.g. for passing the result to other expressions, certain function calls
160      or variables which are not accepting any units (or that specific unit).
161    - NKSP language: integer arrays and real number arrays can now be converted
162      to strings (e.g. for dumping their content with message() calls for
163      script debugging purposes).
164    - NKSP language: expressions and variables with units are now correctly
165      casted to strings (e.g. with message() calls).
166    - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
167      unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
168      floating point tolerances into account.
169    - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
170      VMScalarNumberExpr::evalCastReal().
171    - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
172      'VMIntArrayExpr' and 'VMRealArrayExpr'.
173    - NKSP VM API: replaced all unitPrefix() (parse time) methods by
174      unitFactor() (runtime) methods.
175    - Built-in function "exit()" supports now returning units and 'final'ness
176      for test cases.
177    - The following built-in functions support now units as well: "abs()",
178      "random()", "inc()", "dec()", "in_range()", "min()", "max()",
179      "real_to_int()", "int()", "int_to_real()" and "real()".
180    - Built-in functions "array_equal()", "search()" and "sort()" support now
181      real number arrays (correctly) as well.
182    - Added individual parse time checks of arguments to be passed to built-in
183      functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
184      "array_equal()" and "search()" specific for their individual purposes.
185    - NKSP VM refactoring: Renamed all methods, functions and classes matching
186      pattern *ScalarNumber* to simply *Number* (that is i.e. classes
187      VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
188      ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
189      NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
190      method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
191      isScalarNumber() -> isNumber()).
192    - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
193      evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
194      evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
195      as convenient methods for automatically converting values to expected
196      metric value basis.
197    - Built-in function "wait()" accepts now both integers and real numbers as
198      argument.
199    - NKSP VM API cleanup: Get rid of legacy method
200      VMFunction::argType(vmint iArg) which was already superseded by its new
201      replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
202    - NKSP parser: if wrong argument type was passed to a built-in function and
203      that built-in function accepts more than one data type for the argument,
204      then show all supported data types as parser error message.
205    - Built-in function "play_note()" accepts now real numbers and seconds as
206      unit type as well for its 3rd and 4th function arguments.
207    - The following built-in functions accept now real numbers as well for their
208      2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
209      "change_attack()", "change_decay()", "change_release()",
210      "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
211      "change_cutoff_sustain()", "change_cutoff_release()",
212      "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
213      "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
214      "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
215    - Fixed built-in function "change_play_pos()" not having accepted metric
216      prefixes at all.
217    - Fixed the following built-in functions having misinterpreted values given
218      with unit type (for their 2nd argument) as if they were relative values
219      (that is as if they were passed without a unit type): "change_attack()",
220      "change_decay()", "change_release()", "change_cutoff_attack()",
221      "change_cutoff_decay()", "change_cutoff_release()".
222    - Fixed the following built-in functions having applied completely wrong
223      'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
224      respective EGs being their modulation sink assume uint data type with
225      value range 0..1000 instead of 0.0..1.0.
226    - Added individual parse-time checks of function arguments for the following
227      built-in functions: "play_note()", "note_off()", "set_event_mark()",
228      "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
229      "change_decay()", "change_release()", "change_cutoff_attack()",
230      "change_cutoff_decay()", "change_cutoff_release()",
231      "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
232      "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
233      "change_pan_time()".
234    - Don't abort function call if unit type was used and at the same time
235      'final' operator was omitted for the primary value argument of the
236      following built-in functions: "change_cutoff()", "change_attack()",
237      "change_decay()", "change_release()", "change_cutoff_attack()",
238      "change_cutoff_decay()", "change_cutoff_release()",
239      "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
240      "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
241      "change_pan_time()", instead imply 'final'ness at runtime and raise an
242      appropriate parser warning at parse time.
243    - Added built-in real number functions "round()", "ceil()", "floor()",
244      "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
245      "cos()", "tan()", "asin()", "acos()", "atan()".
246    - Added built-in script real number constant "~NI_MATH_PI".
247    - Added built-in script real number constant "~NI_MATH_E".
248    - NKSP language: Allow unary '+' operator.
249    - Added built-in script functions "msb()" and "lsb()".
250    - NKSP language: Added support for RPN event handler
251      ("on rpn ... end on" in instrument scripts).
252    - NKSP language: Added support for NRPN event handler
253      ("on nrpn ... end on" in instrument scripts).
254    - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
255      may be read from the new RPN/NRPN script handlers to get the (N)RPN
256      parameter that had been changed and its new value.
257    - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
258      which are identifying the new (N)RPN handlers as such at script runtime.
259    - Implemented built-in script function "set_rpn()".
260    - Implemented built-in script function "set_nrpn()".
261    - Fix: built-in functions returning an array type were broken and caused a
262      crash when the built-in function's (supposed to be array) result value was
263      used by the script VM.
264    - Removed upper value constraint for 2nd argument of built-in functions
265      "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
266      "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
267      "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
268      "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
269      the LFO frequency / resonance / cutoff frequency.
270    - Reduced code involved for parsing NKSP variable declarations by using 2
271      generalized grammar rules with optional components (i.e. optional value
272      assignment and optional variable qualifiers) instead of previous linear
273      combinations of grammar rules, which also fixes some edge case.
274    - NKSP language parser: track code block locations also by a) raw byte
275      position in NKSP source code string and b) length of that code block in
276      bytes (along to the already existing code block tracking by line/column);
277      and added appropriate new members to public C++ API classes like
278      'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
279    - NKSP language: Added support for 'patch' variable qualifier (capture their
280      locations and allow replacement of their assignment expression via VM C++
281      API).
282    - Fixed incorrect EG times if standard measuring unit was passed to built-in
283      functions "change_attack()", "change_decay()" or "change_release()".
284    - Fixed intermediate function result values never having reflected any
285      standard measuring unit type.
286    - Fixed re-entrant issue with function calls which caused wrong result
287      values if the same function was called multiple times in a term
288      (specifically if metric prefixes were used).
289    - NKSP language: Just throw a warning, not an error if an array variable of
290      size zero was declared.
291    - NKSP language: Allow omitting explicit array size on array variable
292      declaration if combined with immediate value assignment
293      (e.g. declare %foo[] := ( 1, 2, 3 ) ).
294    - NKSP language: emit warning if an array variable was declared with bigger
295      array size than amount of initial values been assigned, and initialize the
296      missing array elements with zero in this case.
297    - Fixed built-in NKSP exit() function to behave as return statement.
298    - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
299      data type.
300    - NKSP VM: Fixed the "release" handler being executed too often under
301      certain situations if polyphonic data was passed from "note" handler to
302      "release" handler.
303    - Fixed memory leak in NKSP parser: string tokens were allocated as C
304      strings and never freed.
305    - Fixed incorrect polyphonic data transfer from wrong note handler to
306      release handler; which also fixes no release handler being executed
307      sometimes, and due to the latter it also fixes potential crashes as some
308      polyphonic script events were never released and the engine hence was
309      running out of free script events.
310    - Fixed crash when handling array results of built-in functions
311      (e.g. "num_elements(by_marks($MARK_1)").
312    - NKSP VM: Fixed dead note events not been removed from user's event groups
313      (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
314      and set_event_mark() after max. size of event group list was exhausted).
315
316  * test cases:
317    - Fixed compiler errors in test cases.
318    - Updated README for how to compile & run test cases.
319    - Updated test case
320      MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
321      expected behaviour of the Mutex class implementation (recursive
322      mutex type).
323    - Added test cases for NKSP core language aspects and core built-in
324      functions.
325    - Fixed thread tests segfaulting on Linux.
326    - NKSP: Added real number test cases for built-in functions exit(),
327      int_to_real(), real(), real_to_int() and int(), as well as for the
328      plus, minus and negate language operators.
329    - Added massive amount of NKSP test cases for standard measuring units and
330      'final' operator usage cases.
331    - Added NKSP test cases for (floating point tolerance aware) real number
332      equalness / unequalness comparison.
333    - Added NKSP int array and real array tests for value assignment and
334      initialization of arrays.
335    - Added NKSP test cases for built-in functions "round()", "ceil()",
336      "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
337      "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
338    - Added NKSP test cases for unary '+' operator.
339    - Added NKSP test cases for core built-in variables.
340    - Added thorough NKSP test cases for variable declarations.
341
342  * GigaStudio/Gigasampler format engine:
343    - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
344      behaviour for start_level_mid.
345    - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
346      level (see discussion "GigaStudio LFO compatibility" on mailing list
347      from 2019-09-26 for details).
348    - Changed default wave form for all 3 LFOs to sine (instead of triangle;
349      see discussion "GigaStudio LFO compatibility" on mailing list from
350      2019-09-26 for details).
351    - Format extension: Added support for different LFO wave forms (currently
352      either sine [default], triangle, saw or square).
353    - Format extension: Added support for LFO phase displacement (0°..360°).
354    - Format extension: Added support for flipping LFO polarity on LFO 3
355      (in the original gig format this was only available for LFO 1 and LFO 2).
356    - Format extension: Support for additional filter types:
357      lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
358      bandreject 2-pole.
359    - Fixd potential crash with polynomial interpolator and max. pitch.
360    - If minimum cutoff is defined, remap cutoff controller CC values to really
361      span the entire possible cutoff range (and avoiding a dead controller
362      zone).
363    - Implemented support for loading instrument scripts with 'patch' variables
364      (by patching these script variables with potentially overridden ones by
365      gig Instrument).
366
367  * SFZ format engine:
368    - Fixed support for regions with loccN/hiccN conditions on more than one
369      MIDI controller.
370    - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
371      'xfin_lovel' (patch by Christian Czezatke).
372
373  * Benchmarks:
374    - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
375      algorithm (since result of 2nd run was not accumulated).
376    - Added benchmark for saw wave (benchmarks/saw.cpp).
377    - Added benchmark for sine wave (benchmarks/sine.cpp).
378    - Added benchmark for square wave (benchmarks/square.cpp).
379    - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
380      which are large enough on modern systems.
381
382Version 2.1.1 (27 Jul 2019)
383
384  * Real-time instrument scripts:
385    - Fixed behavior of built-in NKSP functions change_sustain(),
386      change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
387      and change_cutoff_release().
388
389  * general changes:
390    - Only play release trigger samples on sustain pedal up if this behaviour
391      was explicitly requested by the instrument (otherwise only on note-off).
392    - Fixed compiler warnings.
393    - Fixed compilation error when cross-compiling to Mac.
394    - FX Sends: Provide more useful error messages on routing problems
395      (see bug #169).
396    - LSCP doc: Be more clear describing the two distinct approaches
397      of using external vs. internal effects (see bug #169).
398    - "optional" class: Fixed comparison operators.
399
400  * Gigasampler/GigaStudio format engine:
401    - Format extension: If requested by instrument then don't play release
402      trigger sample on note-off events.
403
404  * SFZ format engine:
405    - Fixed memory leak when releasing samples
406      (fixes bug #307, patch by Jacek Roszkowski)
407    - Fixed potential crash when a sample is shared by more than one region
408      (fixes bug #308, patch by Jacek Roszkowski).
409    - Opcode 'sample': Added support for built-in sample '*silence'
410      (fixes bug #310, patch by Jacek Roszkowski).
411
412Version 2.1.0 (25 Nov 2017)
413
414  * SFZ format engine:
415    - added support for <global>, <master> and #define (patch by Alby M)
416    - Removed code duplication in SFZ file loading code.
417    - Added support for sfz extension opcode 'script' which may be used to
418      load real-time instrument script file (NKSP script language).
419    - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
420    - Fixed unintended volume fade-in of voices under certain conditions.
421    - sfz parser: allow missing space between header and opcode
422
423  * Gigasampler/GigaStudio format engine:
424    - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
425      cutoff settings.
426    - Got rid of resembling an ancient GSt misbehavior which did not pitch at
427      all if an up-pitch of more than 40 semi tones was requested (I don't
428      think there is any stock gig sound that requires this behavior to
429      resemble its original sound).
430    - Added support for controlling whether the individual EGADSR stages may
431      be aborted (as LinuxSampler extension to the original GigaStudio 4
432      format).
433
434  * general changes:
435    - fixed printf type errors (mostly in debug messages)
436    - use unique_ptr instead of auto_ptr when building with C++11
437    - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
438      allowing to sort data efficiently in real-time safe manner.
439    - RTList class: added methods for moving/inserting elements to arbitrary
440      position within a list.
441    - RTList class: added method fromPtr() for creating an Iterator object from
442      a raw element pointer.
443    - Attempt to partly fix resetting engine channels vs. resetting engine, an
444      overall cleanup of the Reset*(), ConnectAudioDevice(),
445      DisconnectAudioDevice() API methods would still be desirable though,
446      because the current situation is still inconsistent and error prone.
447    - Active voices are now internally grouped to "Note" objects, instead of
448      being directly assigned to a keyboard key. This allows more fine graded
449      processing of voices, which is i.e. required for certain instrument
450      script features.
451    - Fix: Release trigger voices were not spawned on sustain pedal up
452      (CC #64) events.
453    - Fix: Release trigger voices can now also distinguish correctly between
454      note-off and sustain pedal up events.
455    - All engines: Increased ramp speed of volume smoother and pan smoother
456      (while slow rate of crossfade smoother is preserved) to allow quick
457      volume and pan changes by instrument scripts for instance.
458    - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
459      properly and thus were ignored for certain uses.
460    - Added new C++ API method
461      VirtualMidiDevice::SendChannelPressureToSampler().
462    - windows, 32-bit: fixed potential crashes by making sure the stack in
463      sub threads is 16-byte aligned
464    - fixed numerous compiler warnings
465    - Fixed invalid (note-on) event ID being assigned to new Note objects.
466    - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
467      fixes potential undefined behavior.
468    - Fixed Note object leak when triggering notes on keys which did not
469      have a valid sample mapped (fixes bug #252).
470    - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
471    - linuxsampler binary fix: option --create-instruments-db ignored
472      subsequent optional argument due to glibc's implementation oddity
473      which expects a "=" sign, but no space between them.
474
475  * packaging changes:
476    - removed unnecessary dependency to libuuid
477      (originated by libgig's usage of it)
478    - Automake: set environment variable GCC_COLORS=auto to allow GCC to
479      auto detect whether it (sh/c)ould output its messages in color.
480    - Debian: Fixed packaging error about invalid "Source-Version"
481      substitution variable.
482    - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
483    - Debian: Added build dependency to libsqlite3-dev for building
484      linuxsampler with instruments DB support.
485
486  * Real-time instrument scripts:
487    - Implemented scheduler for delayed MIDI events and for suspended scripts.
488    - Built-in script function "wait()": implemented support for function's
489      "duration-us" argument, thus scripts using this function are now
490      correctly resumed after the requested amount of microseconds.
491    - Built-in script function "play_note()": implemented support for
492      function's "duration-us" argument, thus notes triggered with this
493      argument are now correctly released after the requested amount of
494      microseconds.
495    - Fix: script events were not cleared when engine channel was reset,
496      potentially causing undefined behavior.
497    - Fixed crash which happened when trying to reference an undeclared
498      variable.
499    - Built-in script function "play_note()": Added support for passing
500      special value -1 for "duration-us" argument, which will cause the
501      triggered note to be released once the original note was released.
502    - Instrument script classes now exported with the liblinuxsampler C++ API.
503    - Added new API method ScriptVM::syntaxHighlighting() which provides
504      a convenient syntax highlighting backend for external instrument
505      script editor applications.
506    - Added new C++ API class "ScriptVMFactory".
507    - Extended parser issues to provide not only first line and first
508      column, but also last line and last column of issue (thus marking
509      the precise span of the issue within the source code).
510    - Reload script automatically after being modified by an instrument
511      editor.
512    - NKSP language grammar correction: allow empty event handler bodies
513      like "on note end on".
514    - Implemented built-in script function "change_vol()".
515    - Implemented built-in script function "change_tune()".
516    - Implemented built-in script function "change_pan()".
517    - Implemented built-in script function "change_cutoff()".
518    - Implemented built-in script function "change_reso()".
519    - Implemented built-in script function "event_status()".
520    - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
521      "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
522      "event_status()" function.
523    - NKSP language: Added support for bitwise operators ".or.", ".and."
524      and ".not.".
525    - NKSP language scanner: Fixed IDs matching to require at least one
526      character (i.e. when matching function names or variable names).
527    - NKSP language scanner: disabled unusued rules.
528    - Fixed behavior of play_note() and note_off() functions which must
529      be distinguished engine internally from "real" MIDI note on/off
530      events in order to avoid misbehaviors like hanging notes.
531    - Implemented built-in script variable "$KSP_TIMER".
532    - Implemented built-in script variable "$NKSP_REAL_TIMER".
533    - Implemented built-in script variable "$NKSP_PERF_TIMER".
534    - Implemented built-in script variable "$ENGINE_UPTIME".
535    - Implemented built-in script function "inc()".
536    - Implemented built-in script function "dec()".
537    - NKSP language fix: division expressions were evaluated too often.
538    - NKSP language fix: string concatenation operator was right
539      associative instead of left (to right).
540    - NKSP language correction: allow empty statements in entire language
541      (i.e. "if end if").
542    - Implemented built-in script function "stop_wait()".
543    - Implemented built-in script variable "$NI_CALLBACK_ID".
544    - Implemented built-in script variable "$NI_CALLBACK_TYPE".
545    - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
546    - Added support for read-only built-in variables (respectively
547      handled by the script parser).
548    - Added built-in script constant "$NI_CB_TYPE_INIT".
549    - Added built-in script constant "$NI_CB_TYPE_NOTE".
550    - Added built-in script constant "$NI_CB_TYPE_RELEASE".
551    - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
552    - NKSP Language: Added support for user defined script functions.
553    - Implemented built-in script function "change_attack()".
554    - Implemented built-in script function "change_decay()".
555    - Implemented built-in script function "change_release()".
556    - Fixed all change_*() built-in script functions to apply their
557      synthesis parameter changes immediately in case the respective note
558      was triggered at the same time, instead of scheduling the parameter
559      change, especially because it would cause some parameter types's
560      changes either to be ramped (i.e. change_vol()) or other types even
561      to have not effect at all (i.e. change_attack()).
562    - Implemented built-in script function "sh_left()".
563    - Implemented built-in script function "sh_right()".
564    - Implemented built-in script function "min()".
565    - Implemented built-in script function "max()".
566    - NKSP Fix: "init" event handler was not always executed when a script
567      was loaded.
568    - NKSP built-in wait() script function: abort script execution if
569      a negative or zero wait time was passed as argument (since this is
570      a common indication of a bug either of the script or even of the
571      engine, which could lead to RT instability or even worse).
572    - ScriptVM: Implemented automatic suspension of RT safety
573      threatening scripts.
574    - Provide more user friendly error messages on syntax errors.
575    - Fixed NKSP parser warning "Not a statement" when assigning an
576      initializer list to an array variable.
577    - Implemented built-in script array variable "%ALL_EVENTS".
578    - Implemented built-in script function "in_range()".
579    - Implemented built-in script function "change_amp_lfo_depth()".
580    - Implemented built-in script function "change_amp_lfo_freq()".
581    - Implemented built-in script function "change_pitch_lfo_depth()".
582    - Implemented built-in script function "change_pitch_lfo_freq()".
583    - Implemented built-in script function "change_vol_time()".
584    - Implemented built-in script function "change_tune_time()".
585    - Implemented built-in script function "fade_in()".
586    - Implemented built-in script function "fade_out()".
587    - Fixed acceptance of wrong data type of parameters passed to built-in
588      script functions "change_vol()", "change_tune()", "change_pan()",
589      "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
590      "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
591      "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
592    - Added built-in script function "get_event_par()" and implemented some
593      of its possible parameter selections.
594    - Added built-in script function "set_event_par()" and implemented some
595      of its possible parameter selections.
596    - Fixed a bunch of scheduler time related bugs.
597    - Fixed polyphonic variables not being reset to zero after usage.
598    - Built-in "ignore_event()" function: argument is now optional, like with
599      built-in function "ignore_controller()".
600    - Implemented built-in script function "change_velo()".
601    - Implemented built-in script function "change_note()".
602    - Adjusted behavior of "change_vol()" and "change_tune()" to a more
603      intuitive behavior if used in combination with "change_vol_time()" or
604      "change_tune_time()" respectively: now tuning/volume changes are only
605      assigned (without delay) immediately to a new note if the respective
606      timing function has not been called before, otherwise the volume/tuning
607      changes are automatically faded (before, only the event's time stamp was
608      relevant).
609     - Implemented built-in script function "array_equal()".
610     - Implemented built-in script function "search()".
611     - Implemented built-in script function "sort()".
612     - NKSP Fix: Never suspend "init" event handlers.
613     - Implemented built-in script function "same_region()" (currently only
614       available for gig format engine).
615     - Added built-in script constant "$NKSP_LINEAR".
616     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
617     - Implemented built-in script function "change_vol_curve()".
618     - Implemented built-in script function "change_tune_curve()".
619     - built-in "play_note()" function now supports a sample playback start
620       offset with argument 3, where special value -1 means to use the regular
621       sample offset as defined by the instrument file.
622     - Built-in array variable %KEY_DOWN[] is now a read-only variable.
623     - Built-in variable $EVENT_NOTE is now a read-only variable.
624     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
625     - built-in "play_note()" function now accepts -2 for its fourth argument
626       (note duration) which means the life time of the note shall be sticked
627       to the requested note number of argument 1.
628     - Fix: built-in "play_note()" function now returns 0 as result value if
629       -1 was passed for its fourth argument (note duration) and the respective
630       parent note is already gone.
631    - Implemented built-in script function "change_play_pos()".
632    - NKSP language: Added support for user declared const array variables.
633    - NKSP language: Raise parser warning if array variable is accessed with
634      an index that exceeds the array's size.
635    - NKSP language fix: Unknown characters were not handled correctly.
636    - NKSP language: Added support for "synchronized .. end synchronized"
637      code blocks.
638    - Implemented built-in script function "abort()" which allows to abort
639      another script handler by passing its callback ID.
640    - Fixed potential memory access bug and potential undefined behavior of
641      "init" event handlers.
642    - Print a time stamp along to each call of built-in function "message()".
643    - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
644      to retrieve all code blocks filtered out by the preprocessor.
645    - Added built-in script function "fork()".
646    - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
647    - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
648    - Fixed potential crash when accessing dynamic built-in array variables.
649    - Added built-in script function "callback_status()".
650    - Added built-in constant $CALLBACK_STATUS_TERMINATED.
651    - Added built-in constant $CALLBACK_STATUS_QUEUE.
652    - Added built-in constant $CALLBACK_STATUS_RUNNING.
653    - Removed max. value limitation of built-in functions "change_attack()",
654      "change_decay()" and "change_release()" to i.e. allow passing 2000000
655      for doubling the respective time.
656    - NKSP script editor syntax highlighting API: Fixed app termination due
657      to a lexer start condition stack underrun.
658    - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
659      USE_CODE_IF_NOT() preprocessor statements.
660    - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
661      can be set to disable all subsequent built-in "message()" function calls
662      on preprocessor level.
663    - Implemented built-in script function "change_sustain()".
664    - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
665      to avoid the editor app to crash on ill-formed text input.
666    - Added built-in script function "change_pan_time()".
667    - Added built-in script function "change_pan_curve()".
668    - Added built-in script function "change_cutoff_attack()".
669    - Added built-in script function "change_cutoff_decay()".
670    - Added built-in script function "change_cutoff_sustain()".
671    - Added built-in script function "change_cutoff_release()".
672    - Added built-in script function "change_cutoff_lfo_depth()".
673    - Added built-in script function "change_cutoff_lfo_freq()".
674
675  * Instruments DB:
676    - Fixed memory access bug of general DB access code which lead to
677      undefined behavior.
678    - Cleanup of instruments DB file creation and opening code.
679    - The instrument DB path of linuxsampler's --create-instruments-db argument
680      is now optional, if it is missing, then a default location is used.
681    - Added support for scanning SFZ (.sfz) files.
682    - Added support for scanning Sound Font (.sf2) files.
683    - Fixed undefined DB transaction behavior.

725  * general changes:
726    - Refactoring: moved the independent code from
727      the Gigasampler format engine to base classes
728    - command line option '--profile' is currently disabled, since the
729      respective profiling code is currently broken
730    - Introduced support for optional environment variable
731      "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
732      where the sampler shall look for instrument editor plugins
733      (patch by Luis Garrido, slightly modified).
734    - implemented Roland GS NRPN 1ArrH which allows to set volume per note
735    - implemented Roland GS NRPN 1CrrH which allows to set pan per note
736    - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
737      note (in this implementation of the sampler its simply hard routed to
738      the 1st effect send of the sampler channel, no matter what the actual
739      effect type is)
740    - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
741      note (in this implementation of the sampler its simply hard routed to
742      the 2nd effect send of the sampler channel, no matter what the actual
743      effect type is)
744    - implemented support for internal LADSPA effects
745    - raised limit of program change queue from 100 to 512
746      (as suggested by Alex Stone)
747    - implemented sine LFO, pulse LFO and saw LFO
748    - experimental support for per voice equalization
749    - added command line option --exec-after-init
750    - Introduced new C++ API method:
751      EngineChannel::InstrumentFileName(int index)
752      allowing to retrieve the whole list of files used for the loaded
753      instrument on an engine channel (a.k.a. part). Some GigaStudio
754      instruments for example are splitted over several files like
755      "Foo.gig", "Foo.gx01", "Foo.gx02", ...
756    - Added new C++ API method Sampler::GetGlobalMaxVoices().
757    - Added new C++ API method Sampler::GetGlobalMaxStreams().
758    - Added new C++ API method Sampler::SetGlobalMaxVoices().
759    - Added new C++ API method Sampler::SetGlobalMaxStreams().
760    - Various "const" and "restrict" optimizations.
761    - all engines: add pan CC value to instrument pan parameter before
762      applying panning, instead of using two separate pan functions in
763      series (#182)
764    - added a lock guard class for exception safe mutex handling and
765      used it everywhere appropriate
766    - Immediately apply scale tuning changes to active voices.
767    - Exposed scale tuning to C++ API (along to the already existing standard
768      SysEx way).
769    - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
770      and broken for ppc64. (Seq_cst loads and stores are actually not
771      used in LS, so the bug wasn't noticable.)
772    - lsatomic.h: added ARMv7 support
773    - Added support for multiple MIDI input ports per sampler channel (and
774      added various new C++ methods for this new feature / design change, old
775      C++ API methods for managing SamplerChannel's MIDI inputs are now marked
776      as deprecated but are still there and should provide full behavior
777      backward compatibility).
778    - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
779      unsafe and caused compilation error with clang 2.x).
780    - Bugfix: only process the latest MIDI program change event.
781    - Introducing the LSCP shell, which provides convenient control of the
782      sampler from the command line by providing LSCP aware features.
783    - VirtualMidiDevice: Added support for program change.
784    - VirtualMidiDevice: Added support for bank select (MSB & LSB).
785    - VirtualMidiDevice: Added support for pitch bend.
786    - Aftertouch: extended API to explicitly handle channel pressure and
787      polyphonic key pressure events (so far polyphonic pressure was not
788      supported at all, and channel pressure was rerouted as CC128 but not
789      used so far).
790    - Added initial support for real-time instrument scripts. The script VM
791      code is shared by all sampler engine implemementations, however only the
792      gig file format currently provides support for storing instrument scripts
793      (as LinuxSampler extension to the original GigaStudio 4 format).
794
795  * Gigasampler format engine:
796    - implemented the "round robin keyboard" dimension
797    - fixed round robin and random dimensions for cases when number of

801    - bugfix: pitch LFO controller "internal+aftertouch" was broken
802    - bugfix: filter keyboard tracking was broken
803    - filter performance fix (an unnecessary copy was made of the
804      filter parameters in each sub fragment)
805    - handle special case when pan parameter in gig file has max or
806      min value
807    - Exclusive Groups: don't ever stop voices of the same note,
808      doesn't sound naturally with a drumkit
809    - fixed EG1 modulation when attack or release is zero
810    - Fixed support for 'aftertouch' attenuation controller.
811    - Fixed crash that happened with velocity split sounds under certain

833    - fine-tuned the default velocity curve
834    - added support for transpose
835    - fixed crash when using sw_down/up
836    - improved logic for sw_lokey/hikey/up/down/last
837    - added more v1 aliases to parser
838    - reduced memory usage for sfz data
839    - RT-safeness: avoid malloc in audio thread
840    - fixed a bug that could cause voice stealing to fail
841    - optimized sample lookup
842    - improved support for exclusive groups (group, off_by and

990    - AU bugfix: failed to destroy its audio/MIDI devices
991    - Listen to all interfaces on Mac OS X (INADDR_ANY)
992    - VST bugfix: If the host called resume() before and after
993      changing sample rate or block size, the number of channels was
994      incorrectly set to two. This caused silence in Cubase 5.
995    - save engine type (gig, sfz or sf2) in plugin state
996    - VST: when opening Fantasia, look for both 32 and 64 bit Java on
997      64 bit Windows
998    - AU: changed number of output channels from one stereo to 16
999      stereo
1000    - VST: made it possible to build the VST plugin for Mac
1001    - AU: link AU plugin dynamically if --disable-shared isn't
1002      specified
1003    - LV2 "state" extension support (patch by David Robillard)

1005      the plugin was loaded a second time (#174)
1006    - plugin bugfix: instrument loading hang when the plugin was
1007      loaded a second time (this time it's for Linux and Mac, previous
1008      similar fix was for Windows)
1009    - thread safety fixes for the instrument loading thread
1010    - LV2: use the new lv2 package if present
1011    - VST: try to open Fantasia automatically on Linux and Mac too (on
1012      Linux, the Fantasia jar should be placed in <prefix>/share/java)
1013    - VST: fixed crashes on Linux Ardour and EnergyXT
1014    - DSSI bugfix: it wasn't possible to change engine type. The MIDI
1015      port and audio channel routing for DSSI plugins are now visible.
1016    - LV2: use urid and atom extensions instead of deprecated uri-map
1017      and event
1018    - LV2: lv2 package 1.0 is now required to build the LV2 plugin
1019    - LV2: changed number of output channels to 16 stereo, just like
1020      the VST and AU plugins
1021    - LV2: fixed save/restore of SFZ state (patch by David Robillard)

1024      sampler's internal MIDI instrument mapping system
1025

1027    - Changed instrument editor plugin interface, providing additional
1028      informations like the EngineChannel for which the instrument editor was
1029      spawned for. This allows the instrument editors to interact more actively
1030      with the sampler.
1031
1032  * MIDI driver:
1033    - ALSA MIDI driver supports now "NAME" device parameter, for overriding
1034      the ALSA sequencer client name
1035    - removed limit of maximum amount of MIDI ports per MIDI device, since
1036      there is no reason for this limit
1037    - MME: fixed memory handling bug found with cppcheck
1038    - MME: removed compiler warning
1039    - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
1040      which allows to retrieve the list of CoreMIDI clients / ports and to connect
1041      to them a la JACK, via the usual sampler APIs
1042    - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1043      the driver will automatically connect to other CoreMIDI clients' ports
1044      (e.g. external MIDI devices being attached to the Mac)
1045    - added support for MIDI note on velocity filter
1046    - CoreMIDI: fixed memory deallocation error
1047    - Fixed variable underflow in VirtualMidiDevice, which caused graphical
1048      virtual keyboards in frontends / instrument editors being stuck.
1049    - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
1050    - Implemented missing handling of MIDI "running status".
1051    - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
1052    - MME bugfix: driver wasn't closed properly
1053    - CoreMIDI: automatically connect to all input sources by default (driver
1054      parameter "AUTO_BIND").
1055    - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
1056    - CoreMIDI: fixed minor memory leak
1057
1058  * audio driver:
1059    - ASIO driver fixes for newer gcc versions (fix from PortAudio)

1143      engine, which extends the general instrument script VM with Giga format
1144      specific variables and functions.
1145    - Giga format scripts: added built-in script int constant variables
1146      $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

1178      channel to a different engine type
1179    - fixed crash when deleting a sampler channel or changing engine
1180      type while an instrument load was in progress
1181    - bugfix: playing a note while changing the instrument could cause
1182      a crash, or give "Handing back unknown region" error messages
1183    - bugfix: calling SET VOICES (which Fantasia does on start and
1184      refresh) could cause instruments to be unloaded
1185    - Mac OS X: fixed name collision of enum in EffectControl and
1186      wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1187    - Mac OS X: fixed hanging threads
1188    - Windows: disabled the previous thread fix on non-Mac systems, as
1189      it caused hanging threads on Windows
1190    - Fixed possible crashes due to corrupted MIDI/audio device list
1191      after MIDI/audio device creation failure
1192    - When creating MIDI instrument map entries with "PERSISTENT" type, the
1193      instruments were uselessly precached with zero samples, however it still
1194      took the full preloading time and on 1st program change the respective
1195      instrument was completely reloaded again.
1196    - fixed handling of rapid bank select and program change messages
1197      sent to the same sampler channel (patch from the Open Octave
1198      project, slightly adjusted)
1199    - fixed crash when trying to create an effect instance with controls
1200      which min and/or max values depend on the sample rate

1202    - bugfix: LADSPA_PATH was not evaluated correctly when containing
1203      multiple paths (#165)
1204    - thread safety fixes for the instrument loading thread
1205    - bugfix: instrument loading crashed for sfz and sf2 in Ardour

1211      introduced in previous fix)
1212    - fixed crash when a channel received a program change while
1213      playing a note in a key group
1214    - fixed erroneous error message piping in VoiceBase.h
1215      (labelled "Disk stream not available in time")
1216    - Update effects on sample rate & period size changes (to avoid
1217      crashes and noise on such transitions).
1218    - ignore missing LADSPA paths without ignoring valid LADSPA paths
1219      (fixes #208)
1220    - Fixed bug in LSCP grammar definition which caused a statement like
1221      "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1222      practically irrelevant, however it caused problems with the new LSCP
1223      shell's auto completion feature).
1224    - Fixed MIDI program change messages being ignored if quickly executed
1225      after each other (fixes #231).
1226
1227Version 1.0.0 (31 July 2009)
1228
1229  * packaging changes:
1230    - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1231      causing e.g. the libgig test to fail when
1232      "./configure --disable-jack-driver" was used
1233      (patch by Alexis Ballier)
1234    - fixed compilation with gcc 4.3
1235    - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1236    - fixed configure so it detects x86_64 (#107)
1237    - fixes for building with newer MinGW versions
1238    - fix for building with bison 2.4 (#111)
1239    - fixed building with libgig installed in a non-standard directory
1240    - minor fix in configure for mmsystem.h detection on MinGW
1241    - Windows: look for editor plugins and Fantasia using base
1242      directory of liblinuxsampler dll (look in the same directory and one
1243      directory above)
1244    - configure script fix: removed unconditional use of SSE
1245    - fixed building with sqlite installed in a non-standard directory
1246    - when cross-compiling, don't try to create instruments.db
1247    - fix for new mingw-w64 version, which has usleep
1248
1249  * general changes:
1250    - bugfix: on some POSIX systems instrument editor plugins refused to
1251      load as we used a non-portable Linux specific struct field
1252      (fixes bug #70, patch by Ronald Baljeu)
1253    - fixed endless loop which occured when loading an instrument editor
1254      plugin DLL on Windows systems failed
1255    - fixed memory leaks that occurred when liblinuxsampler was unloaded
1256    - optimized the SynchronizedConfig class so it doesn't wait
1257      unnecessarily long after an update
1258    - added support for notifying instrument editors on note-on / note-off
1259      events (e.g. to highlight the pressed keys on the virtual keyboard
1260      of gigedit)
1261    - added support for triggering notes by instrument editors (see above)
1262    - be verbose on DLL load errors (on Linux)
1263    - fixed di-harmonic triangle LFO implementation (this LFO implementation
1264      is only used by very few systems, most pick the int math
1265      implementation, which is usually faster)
1266    - fixes for audio drivers with varying buffer sizes
1267    - experimental support for running LinuxSampler as a DSSI, LV2 and
1268      VST plugin
1269    - notification events for stream/voice count statistics are now sent
1270      only when there are actual changes
1271    - added memory ordering constraints to improve stability on
1272      multi-core and multi-cpu systems
1273    - maximum voices and disk streams can now be altered at runtime
1274    - fixed CPU feature detection on x86_64 (maybe fixes #108)
1275    - automatic stacktrace mechanism is now turned off by default and can
1276      be switched on by command line option "--stacktrace" (the automatic
1277      stacktrace mechanism seems to be broken on most systems at the moment)
1278    - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1279      a pointer to the launched InstrumentEditor object
1280    - added optional 3rd party user data parameter for following
1281      liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1282      InstrumentEditor::Launch(),
1283      InstrumentManager::LaunchInstrumentEditor()
1284    - theoretical fix: made SynchronizedConfig follow C++0x memory
1285      model more strictly
1286    - fixes for using large audio device buffers
1287    - Windows: add the installation directory to the DLL search path
1288      when loading an editor plugin (solves problems with VST and
1289      gigedit on systems with other GTK versions installed)
1290    - updated linuxsampler man page
1291
1292  * audio driver:
1293    - removed the nonsense audio channel constraint (which was hard coded to
1294      max. 100 audio channels) for most audio drivers
1295    - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1296      opposed to the LSCP specs
1297    - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1298      reflected the wrong value
1299    - fixed a memory management bug in ASIO driver
1300    - Makefile fix: JACK_CFLAGS wasn't used
1301    - JACK: use jack_client_open instead of the deprecated
1302      jack_client_new
1303    - added (experimental) CoreAudio driver
1304    - applied old fixes to the ASIO driver that were included in the
1305      previous binary release but accidentally never committed to CVS
1306      (fixes #117)
1307    - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1308      win64)
1309    - VST: added support for sample rate and buffer size changes
1310    - VST: close editor (Fantasia) when the VST is removed
1311    - VST: avoid opening Fantasia more than once for each VST instance
1312    - VST: export main function as "main" on Linux too (fix for
1313      energyXT)
1314    - VST: changed number of output channels from one stereo to 16
1315      stereo
1316    - added channel routing, fxsends and midi maps to the settings
1317      stored in the plugin state
1318    - performance optimization of AudioChannel::MixTo() and
1319      AudioChannel::CopyTo() methods using GCC vector exensions
1320      (if available)
1321    - ASIO fixes: avoid initializing the device twice, avoid throwing
1322      exception when getting parameters from a disconnected device
1323
1324  * MIDI driver:
1325    - added JACK MIDI driver
1326    - dispatch bank select as ordinary CC as well, the user might seriously
1327      want to (mis)use it for some purpose ("fixed" in all current MIDI
1328      input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1329    - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1330      CoreMidi or AU
1331    - fixed mingw-w64 compilation error in MME driver
1332    - made program change handling in MIDI thread real-time safe by
1333      moving the logic to a non-RT thread
1334    - fixed minor memory leak in ALSA driver
1335
1336  * instruments database:
1337    - avoid time consuming samples scanning when adding instruments
1338      to the instruments database
1339    - added support for handling lost files in the instruments database
1340    - Implemented option for adding instruments in separate directories
1341      in the instruments database
1342      (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1343    - work-around for missing fnmatch function on Windows to make
1344      instrument database compilable
1345    - added instrument database support on Windows
1346      works with both standalone mode and VST plugin.
1347      the instruments DB file is located in
1348      %USERPROFILE%\.linuxsampler\instruments.db which allows different
1349      databases for each windows user
1350      if no DB is present it automatically creates the .linuxsampler subdir
1351      and then creates an empty DB
1352    - fixed recursive import, which was broken on Windows
1353
1354  * Gigasampler format engine:
1355    - fixed a memory leak that could happen when a channel was deleted
1356      while notes were playing
1357    - made it possible to load an instrument even if the audio thread
1358      isn't running
1359    - added partial support for the "Controller Triggered" MIDI rule,
1360      enough for piano gigs with pedal noise samples
1361    - minor fix: only mark FX sends as being modified if really the
1362      respective FX send MIDI controller was used
1363    - added support for GM global device volume SysEx message
1364      (can be selected at compile time to either apply globally to the
1365      whole sampler [default] or only to the sampler channels that are
1366      connected to the respective MIDI input port the SysEx message arrived
1367      on)
1368    - bugfix: notes triggered at position 0 in the audio buffer were
1369      sometimes wrongly killed in the same buffer, causing no sound to
1370      be played
1371    - added support for chromatic / drumkit mode Roland GS Sysex message
1372      which is usally used to switch a part between chromatic sounds and
1373      drumkit sounds (as opposed to their common default setting of MIDI
1374      part 10 being a drumkit part and all other ones chromatic parts), in
1375      LS however one can switch between the first 16 MIDI instrument maps
1376      defined for the sampler
1377    - made it possible to create multiple sample channels even if the
1378      audio thread isn't running
1379    - fixed crash when removing channel with active voices (#116)
1380    - bugfix: on sample reference changes (instrument editor), only
1381      un-cache the respective sample if it's really not used by any
1382      sampler engine anymore
1383    - re-cache samples in case they were changed by an instrument editor,
1384      e.g. when a sample was added while playing (#82)
1385    - fixed hanging notes which occured when note-off event had the exact
1386      same time stamp as the voice's note-on event and occured both in the
1387      same audio fragment cycle (fixes bug #112)
1388    - added support for the "fine tune" and "pitch bend range"
1389      instrument-level gig parameters
1390    - fixed minor artifacts in pitch bend handling
1391    - added support for GS Reset SysEx message
1392    - allow gig files to use unlimited downward pitch shifting
1393    - added a limit check for upward pitch shifting
1394    - bugfix: sometimes, when playing a note twice fast, the second
1395      note was silent
1396    - fixed crash happening when a pitch bend event arrived at the
1397      same time a new instrument was loading
1398
1399  * LSCP server:
1400    - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1401      react on MIDI data arriving on certain sampler channels (so far only
1402      Note-On and Note-Off events are sent via this LSCP event)
1403    - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1404      react on MIDI data arriving on certain MIDI input devices (so far only
1405      Note-On and Note-Off events are sent via this LSCP event)
1406    - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1407      SET DB_INSTRUMENT FILE_PATH
1408    - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1409      frontends to send MIDI messages to specific sampler channel
1410    - added two additional fields to GET FILE INSTRUMENT INFO command -
1411      KEY_BINDINGS and KEYSWITCH_BINDINGS
1412    - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1413      was incorrect
1414    - Optimized the retrieval of the MIDI instrument mappings
1415    - added new LSCP command "SET VOICES" to globally alter the maximum
1416      amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1417      be triggered respectively
1418    - added new LSCP command "SET STREAMS" to globally alter the maximum
1419      amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1420      which will be triggered respectively
1421    - bugfix: retry if "select" returns EINTR (this fixes a crash when
1422      a gigedit file dialog is opened)
1423    - close all connections when LSCPServer is deleted
1424    - hard close of all sockets on exit
1425    - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1426      driver
1427
1428  * Bug fixes:
1429    - fixed a crash which occurs when removing a sampler channel waiting
1430      to start instrument loading after another channel
1431    - fixed a crash which occurs when removing a sampler channel with
1432      instrument loading in progress (bug #113)
1433    - fixed termination caused by uncaught exception when adding MIDI
1434      instrument with PERSISTENT load mode
1435    - fixed possible iterator invalidations when resetting the sampler
1436    - fixed memory leaks when issuing the following LSCP commands:
1437      GET AUDIO_OUTPUT_DRIVER INFO
1438      GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1439      GET MIDI_INPUT_DRIVER INFO
1440      GET MIDI_INPUT_DRIVER_PARAMETER INFO
1441    - fixed possible compilation error when sqlite is not present
1442    - fixed orphaned pointers when setting maximum voices limit (bug #118)
1443    - fixed crash when changing the audio output device of a sampler
1444      channel with loaded instrument and start playing notes
1445    - fixed endless loop in Engine::SuspendAll() (bug #120)
1446    - fixed a low-level atomic load function that was broken on 64-bit
1447      PowerPC, which probably could cause crashes on that platform
1448    - fixed a memory management error which could cause a crash when a
1449      plugin was unloaded
1450    - bugfix: two private structs had the same name, which could cause
1451      problems if the linker chose the wrong constructor
1452    - fixed low-level ConditionServer usage bug that caused lockups on
1453      Windows
1454
1455
1456Version 0.5.1 (6 December 2007)
1457
1458  * packaging changes:
1459    - added autoconf checks for pthread library
1460    - added autoconf check for pthread bug found on certain NPTL-enabled
1461      glibc versions (see Gentoo bug report #194076)
1462    - added autoconf checks for MS Windows
1463
1464  * general changes:
1465    - bugfix: the thread used by an editor plugin didn't die when the
1466      editor closed
1467    - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1468      out all the space. operator--() did not apply size_mask after
1469      decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1470      order to avoid problems with the _NonVolatileReader functions.
1471    - bugfix: Stream.h: added a missing divide by BytesPerSample in
1472      GetWriteSpace(). Since this function is currently only used in
1473      the stream's qsort() compare function, it didn't trigger any
1474      bugs.
1475    - Resampler.h, Synthesizer.h: cubic interpolation now works in
1476      24bit mode too. Faster method to read 24bit words on little
1477      endian machines (x86): replaced 3 byte reads + shifts with a 1
1478      unaligned 32bit read and shift
1479    - experimental support for MS Windows (MIDI input via MME, AUDIO
1480      output via ASIO)
1481    - made handling of SIGINT signal (Ctrl-C) a bit more robust
1482    - support for monitoring the total number of active disk streams
1483      (new LSCP commands: GET TOTAL_STREAM_COUNT,
1484      SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1485
1486  * AUDIO driver:
1487    - added Windows ASIO low latency audio driver
1488
1489  * MIDI driver:
1490    - added MME Windows MIDI driver
1491
1492  * LSCP server:
1493    - added support for Windows style path / filenames, however with
1494      forward slash path separators instead of backslash
1495      (i.e. "C:/foo/bar.gig")
1496    - allow naughty liblscp to send non-string device parameters within
1497      apostrophes as well
1498    - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1499      "LIST FILE INSTRUMENTS <file>" and
1500      "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1501      about an arbitrary instrument file on the system where the sampler is
1502      running on
1503
1504Version 0.5.0 (15 October 2007)
1505
1506  * packaging changes:
1507    - config.h is not going to be installed along with liblinuxsampler's
1508      API header files anymore
1509    - only the API relevant header (and source) files will be exported to
1510      the Doxygen API documentation (explicitly listed in Doxyfile.in)
1511    - added completely new XCode project files for Mac OSX which is now
1512      capable to execute our autoconf environment, thus no need anymore
1513      to maintain the compile time configuration file (osx/version.h) for
1514      OSX manually (patch by Toshi Nagata)
1515    - fixed buggy boolean --enable-foo / --disable-foo configure script
1516      parameters
1517    - global.h now only covers global definitions that are needed for the
1518      C++ API header files, all implementation internal global definitions
1519      are now in global_private.h
1520    - atomic.h is not exposed to the C++ API anymore
1521    - no need to include config.h anymore for using LS's API header files
1522    - fixed warnings in API doc generation
1523
1524  * general changes:
1525    - replaced the old, confusing MIDI program change mechanism by a
1526      flexible MIDI instrument mapper which allows to map arbitrary
1527      (MIDI bank, MIDI program) pairs with arbitrary
1528      (engine type, instrument file, file index) triplets which will be
1529      loaded on the respective channel when such MIDI program change
1530      messages arrive, beside that, each entry allows to define a life-time
1531      strategy for the instrument, so the user can define whether the
1532      instrument should i.e. be permanently loaded (to be able to switch
1533      quickly among sounds) or i.e. loaded just on demand when the
1534      respective program change arrives (to safe RAM space), as well as a
1535      global volume factor for each entry, so the user can adjust the volume
1536      dynamic of his mapped instrument collection without having to modify
1537      the instrument files, also one can manage arbitrary amount of such
1538      MIDI instrument maps and assign each sampler channel individually
1539      a certain map, so that i.e. separation of normal instruments and
1540      drumkits is possible
1541    - new notification events for tracking changes to audio/MIDI devices,
1542      MIDI instrument maps, MIDI instruments, FX sends, global volume.
1543    - sampler was limited to load max. 200 instruments in the background
1544      due to a constant size RingBuffer FIFO which is now replaced by a
1545      dynamic (unlimited) size std::list FIFO
1546    - added FX sends, these allow to route audio signals to arbitrary audio
1547      output channels for being processed by external effect processors
1548      (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1549      controllers
1550    - global (sampler wide) volume can now be controlled at runtime
1551    - Implemented new, improved notification system
1552    - fixed compilation errors regarding OSX
1553      (patch by Toshi Nagata)
1554    - implemented instruments database
1555    - added support for escape sequences to the instruments database
1556    - added highly experimental support for on-the-fly instrument editing
1557      within the sampler's process (by using instrument editor plugins),
1558      you'll notice the new "Registered instrument editors:" message on
1559      startup, added a new LSCP command:
1560      "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1561      to spawn a matching instrument editor for the instrument on the
1562      given sampler channel, the plugin path can be overridden at compile
1563      time with ./configure --enable-plugin-dir=/some/dir
1564    - added experimental code for synchronizing instrument editors hosted
1565      in the sampler's process to safely edit instruments while playing
1566      without a crash (hopefully) by either suspending single regions
1567      wherever possible or if unavoidable whole engine(s)
1568    - fixed several issues in fundamental "Thread" class: set scheduling
1569      policy and priority on thread level, set a minimum stack size for
1570      thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1571      threads simply inherited properties of starting thread instead of
1572      setting their own policy and priority
1573    - minor fix in our automatic stack trace mechanism on crashes, the
1574      main process did not wait for the stack trace process to finish
1575      its output
1576    - fixed some minor memory leaks
1577    - reenabled assembly features support, at the moment only for
1578      enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1579    - minor assembly fix in x86 features detection (don't use the PIC
1580      register, to avoid relocations in the text segment at runtime)
1581    - POSIX callback functions of Thread.h are hidden
1582
1583  * MIDI driver:
1584    - dispatch bank select (MSB and LSB) messages
1585
1586  * audio driver:
1587    - the ALSA audio output driver parameters now reflect the correct
1588      parameter value ranges for the respective selected sound card
1589      (patch by Till Wimmer, a bit fixed and extended)
1590
1591  * Gigasampler format engine:
1592    - if a filter is used and EG2 finishes before EG1, let the voice
1593      die when EG2 has finished (this fixes a problem with clicks and
1594      voice starvation for some gigs)
1595    - playback is no longer disabled during instrument loading
1596    - all notes playing on a channel that changes its instrument keep
1597      playing with the old instrument until they get a note off
1598      command
1599    - EG fix: a release value of zero could cause noises or crash
1600    - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1601    - EG fine tuning: when attack is zero the EG starts at a level
1602      above max sustain level, which means that there is a decay phase
1603      even if sustain is 100%
1604    - more EG fixes: the level could sometimes go below zero and cause
1605      noises or crashes
1606    - minor fix of EGDecay (patch by Toshi Nagata)
1607    - fixed compiler error when --enable-override-filter-type was
1608      supplied to the configure script (fixes #46)
1609    - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1610      instead of a fix value
1611    - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1612      127 (solo mode) only kill voices if the respective mode really
1613      changed
1614
1615  * LSCP server:
1616    - fixed compile time error for old Bison versions
1617      (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1618    - parser now supports extended ASCII character set
1619      (up to ASCII code 255, i.e. includes now umlauts and accents)
1620    - filename arguments in LSCP commands now allow to use escape
1621      sequences, that is directly literal as one of: \', \", \\, \n, \r,
1622      \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1623      code value like \xf2) (fixes bug #24)
1624    - the following LSCP commands now also support escape sequences for at
1625      least one of their text-based parameters (i.e. name, description):
1626      "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1627      "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1628      "SET DB_INSTRUMENT_DIRECTORY NAME",
1629      "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1630      "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1631      "FIND DB_INSTRUMENT_DIRECTORIES"
1632    - returns verbose syntax errors (line and column where syntax error
1633      occured, the unexpected character and the actually expected, possible
1634      character(s), the latter only if less than 5 possibilities)
1635    - made sure that LSCP syntax is not affected by gigedit locale
1636      settings
1637    - bugfix regarding strings parameter lists: all comma separated lists
1638      of strings were treated as being one string containing commas
1639      (fixes #57)
1640
1641  * Bug fixes:
1642    - fixed crash occurring on certain LSCP scripts (Bug 39)
1643    - another thread safety fix for lscp "load engine" and "set
1644      channel audio output device"
1645    - fixed a crash which occurs when reassigning the same engine
1646      on a sampler channel with connected MIDI device
1647    - fixed a crash which occurs when changing the number of ports of a MIDI
1648      device connected to a sampler channel to number less then or equal
1649      to the index of the port to which the sampler channel is connected.
1650    - The previous bindings were not been disconnected when altering
1651      the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1652      unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1653    - The active stream/voice count statistic was incorrect.
1654    - notification events were not been sent for some sampler
1655      channel changes
1656    - added default min and max values to restrict the number of allowed
1657      audio output channels and MIDI input ports
1658    - the connection to the PCM interface is now closed when destroying
1659      an audio output device
1660    - files with slash in their path or filename could not be loaded
1661
1662  * test cases:
1663    - updated and fixed (haven't been touched in a while)
1664
1665Version 0.4.0 (24 November 2006)
1666
1667  * packaging changes:
1668    - changed deprecated copyright attribute to license; added ldconfig
1669      to post-(un)install steps; added devel package for liblinuxsampler;
1670      to linuxsampler.spec (RPM)
1671    - install necessary development header files for allowing 3rd party
1672      applications to link against liblinuxsampler
1673    - liblinuxsampler's API documentation can be generated with 'make docs'
1674      (Doxygen required)
1675    - added benchmark to automatically detect the best triangle LFO
1676      implementation (currently either an integer math solution or a
1677      di-harmonic approximation), automatic detection can be overriden
1678      with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1679      configure script argument though (mandatory for cross-compilation)
1680    - do not automatically pick optimized gcc flags if the user already
1681      provided some on his own (as CXXFLAGS)
1682    - added compile time option to disable processing of All-Notes-Off MIDI
1683      messages
1684    - added compile time options to allow disabling the various audio and
1685      MIDI drivers
1686    - fixed automatic GCC CPU switch detection on PPC
1687      (patch by Ebrahim Mayat)
1688
1689  * Gigasampler format engine:
1690    - extensive synthesis optimization
1691      (reimplementation of EGs and LFO(s), removed synthesis parameter
1692      prerendering and the synthesis parameter matrix in general, splitting
1693      each audio fragment into subfragments now where each subfragment uses
1694      constant pitch and filter coefficients. The volume coefficient is
1695      linearly interpolated inside a subfragment, unless
1696      --disable-interpolate-volume is set.)
1697    - fine tuning of the EG modulation parameters
1698    - improved filter cutoff calculation by adding support for the
1699      following gig parameters: Cutoff freq (used when no cutoff
1700      controller is defined), Control invert, Minimum cutoff, Velocity
1701      curve and Velocity range. The keyboard tracking now scales
1702      cutoff frequency instead of resonance.
1703    - added support for gig parameter Resonance.
1704    - fixed bug in sysex handling (patch by Juan Linietsky)
1705    - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1706      which can be overridden with --enable-global-attenuation
1707    - EG fixes: made the length of "attack hold" stage more
1708      accurate. Release stage can now start before attack stage
1709      ends. Cancel release didn't work when sustain was zero. Attack
1710      time now has a minimal value to prevent clicks.
1711    - fixed pitch changes larger than one octave
1712    - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1713    - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1714      all modes can be altered via standard GM messages, that is CC5 for
1715      altering portamento time, CC65 for enabling / disabling portamento
1716      mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1717    - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1718      parameter) and crossfade
1719    - added support for the "attenuation controller threshold" gig
1720      parameter
1721    - added smoothing of volume changes caused by control change
1722      messages
1723    - sample loop parameters are now taken from the DimensionRegion
1724      instead of the wave chunk
1725    - fixed keyswitching for v3 gigs with a number of keyswitch splits
1726      not equal to a power of two
1727    - reimplementation of the filter algorithm. The new filter is more
1728      accurate and supports all gig filter types, including bandreject
1729      and lowpass turbo.
1730    - real support for 24 bit samples - samples are not truncated to
1731      16 bits anymore
1732    - support for aftertouch (channel pressure, not polyphonic
1733      aftertouch)
1734    - LFO1 behaviour fixed (dampening from max volume instead of
1735      amplifying from 0)
1736
1737  * LSCP server:
1738    - fixed application exit on broken pipe error (fixes bug #20)
1739    - fixed the notification messages delay due to lack of
1740      network activity (fixes bug #26)
1741    - fixed parser bug which occured on space(s) within device parameters
1742      (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1743
1744  * audio driver:
1745    - added aRts audio output driver (by no means RT safe)
1746
1747  * MIDI driver:
1748    - fixed legacy sysex code which caused dispatching of MIDI SysEx
1749      messages several times instead of once
1750    - API extension for MIDI drivers which already supply exact time stamps
1751      for events (i.e. for offline rendering based MIDI drivers)
1752    - added checks for bad MIDI data
1753
1754  * linuxsampler application:
1755    - show available sampler engine types on startup
1756
1757  * general changes:
1758    - support for muting sampler channels and solo mode of the same, two new
1759      LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1760      fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1761      introduced for this, the behavior is the same like on a mixer console
1762      (patch by Grigor Iliev, a bit adjusted). Also added configure option
1763      --enable-process-muted-channels which can be used to enable the
1764      processing of muted channels.
1765    - support for sostenuto pedal
1766    - support for monitoring the total number of active voices
1767      (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1768      SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1769    - fixed some memory management errors
1770    - fixed some concurrency problems that could lead to crashes when
1771      LSCP commands were executed
1772    - fixed crash when instrument loading failed previously on the same
1773      sampler channel (fixes bug #36)
1774
1775Version 0.3.3 (15 July 2005)
1776
1777  * packaging changes:
1778    - fixed compilation with gcc 4.0
1779
1780  * Gigasampler format engine:
1781    - LFO preprocessing was performed even though the respective LFO was
1782      disabled by the instrument patch (minor efficiency fix)
1783    - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1784      for volume ramp downs in the same fragment (needed for current voice
1785      stealing implementation) then simply inform the user with a warning
1786      about possible click sounds and reduce the volume ramp down
1787      appropriately instead of cancelling the audio device connection
1788
1789Version 0.3.2 (24 June 2005)
1790
1791  * packaging changes:
1792    - updated autotools build files to compile on OS X
1793      (conditional compilation of CoreMIDI and MidiShare drivers)
1794    - hand-crafted assembly optimization code can be disabled with
1795      './configure --disable-asm' (definitely not recommended)
1796    - fixed 'make dist' rule to include all necessary files
1797    - require automake (>= 1.5) for 'make -f Makefile.cvs'
1798      (due to 'dist-bzip2' automake option)
1799
1800  * Gigasampler format engine:
1801    - support for the gig parameters for "release velocity response" curves
1802    - fine tuning of the EGADSR envelope
1803    - volume of release triggered samples now depends on note-on velocity,
1804      note length and gig parameter "release trigger decay" instead of
1805      note-off velocity.
1806    - revised voice stealing
1807      (fixes crash and endless loop caused by voice stealing)
1808    - don't reset scale tuning on instrument or audio output device change
1809    - handle key group conflicts right at the beginning of each fragment
1810      instead of when the respective voice is actually launched
1811      (fixes undefined behavior if stolen voices belonged to a key group -
1812      this case was followed by a "killed voice survived" error message)
1813    - fixed minor issue with null/silence samples
1814      (those stole voices even though they don't need a voice at all which
1815      resulted in "voice stealing didn't work out" messages)
1816    - don't reset volume, pan, pitch and MIDI controller values on
1817      instrument or audio output device change
