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 -

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. 684 685Version 2.0.0 (15 July 2015) 686 687 * packaging changes: 688 - fixed building with newer MinGW-w64 689 - Mac OS X: support the new dir for Core Audio SDK 690 - Mac OS X: fixed building outside source directory 691 - made sure all source files for hostplugins are included when 692 doing "make dist" 693 -

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).

(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 798 dimension zones is not a power of two 799 - made round robin use a counter for each region instead of each 800 key 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 812 conditions (see also previous commit on libgig). 813 - fixed behaviour of filter LFO 814 815 * SFZ format engine: 816 - Initial implementation (not usable yet) 817 - added support for v2 multiple stage envelope generators 818 - added a fine-tuned v1 envelope generator instead of using the 819 one from the gig engine 820 - fixed memory leak and memory handling errors 821 - added support for trigger=first, trigger=legato and sw_previous 822 - allow non-numerical key values ("C#4" for example) 823 - "key" opcode now sets pitch_keycenter too 824 - fixed error when unloading instrument with same sample used by 825 multiple regions 826 - added some opcode aliases, like loopmode for loop_mode, to be 827 more compatible 828 - added support for trigger=release and rt_decay 829 - added support for off_mode=normal 830 - added support for random, seq_position, seq_length and volume 831 - added v1 LFO opcodes to parser (no support in engine yet) 832 - added support for amp_veltrack and amp_velcurve_N 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 843 off_mode) 844 - added support for controller triggered regions (on_locc/on_hicc) 845 - added support for loop_mode=one_shot 846 - fixed playback of 16 bit wav files on big endian CPUs 847 - added support for Ogg Vorbis sample files 848 - use loop markers from sample file if loop_start and loop_end are 849 not set in sfz file 850 - implemeted filters. Filter types: lowpass, bandpass, bandreject 851 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type, 852 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter, 853 cutoff_cc, cutoff_chanaft. 854 - bugfix: zero ampeg_sustain didn't work 855 - added support for velocity effect on amplifier envelope time 856 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and 857 ampeg_vel2release) 858 -

provide comprehensive error messages on LSCP syntax errors 1107 (suggesting expected next non-terminal symbols) 1108 - Fixed client connection not being closed after network errors. 1109 1110 * LSCP shell: 1111 - Added support for auto correction of obvious and trivial syntax mistakes. 1112 - Added support for auto completion by tab key. 1113 - Show currently available auto completion while typing. 1114 - Added support for browsing command history with up / down keys. 1115 - Show all possible next symbols immediately right to the current command 1116 line while typing (no double tab required for this feature, as it would 1117 be the case in other shells). 1118 - Added support for moving cursor left/right with arrow keys. 1119 - Added support for built-in LSCP reference documentation, which will 1120 automatically show the relevant LSCP reference section on screen as soon 1121 as one specific LSCP command was detected while typing on the command 1122 line. 1123 1124 * Real-time instrument scripts: 1125 -

Pass/preserve polyphonic variable data from respective "note" event 1171 handler to "release" event handler. 1172 - Fixed crash when using built-in script function "by_marks()". 1173 1174 * Bug fixes: 1175 - Fixed crash which may occur when MIDI key + transpose is out of range 1176 - minor valgrind fixes 1177 - fixed crash which occurred when changing an already deployed sampler 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 1201 -

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 -

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 1818 1819 * LSCP server: 1820 - fixed some crashes (patch by Grigor Iliev, fixes #19) 1821 - fixed LSCP event "CHANNEL_INFO" notification 1822 (e.g. did not notify on volume changes or MIDI program change events) 1823 1824 * linuxsampler application: 1825 - added command line parameters --lscp-addr and --lscp-port to override 1826 default IP address and port of LSCP server 1827 1828Version 0.3.1 (24 May 2005) 1829 1830 * initial release 1831
