1class:: MulAdd 2categories:: UGens>Maths 3summary:: Multiply and add to a signal 4 5description:: 6Multiplies the signal by mul and adds add. This UGen is very efficient (it performs various optimisation checks, for example). It is used very heavily throughout SuperCollider to perform multiply and add operations on the server; in fact it is what "really" performs the mul and add arguments found in many UGens. 7 8See also the discussion of mul and add arguments in the link::Classes/UGen:: help file. 9 10classmethods:: 11private:: new1 12 13method:: new 14argument:: in 15input signal 16argument:: mul 17multiply with this value 18argument:: add 19add this value 20 21discussion:: 22Same as: 23code:: 24in.madd(mul, add) 25:: 26 27instancemethods:: 28private:: init 29 30Examples:: 31code:: 32s.boot; 33 34// The mul and add arguments of SinOsc themselves use MulAdd! 35// These two examples will create precisely the same synth graph: 36x = { SinOsc.ar(440, 0, 0.1, 0.05) }.play(s); 37x.trace; // You should see a "MulAdd" in the trace 38x.free; 39 40x = { MulAdd(SinOsc.ar(440, 0), 0.1, 0.05) }.play(s); 41x.trace; 42x.free; 43 44// In fact this will produce the same graph too - the separate multiply and add are optimised into one MulAdd 45x = { SinOsc.ar(440, 0) * 0.1 + 0.05 }.play(s); 46x.trace; 47x.free; 48:: 49(Note: the "trace" message is described in the helpfile for link::Classes/Node::.) 50
