GrainIn Granulate an input signal

GrainIn.ar(numChannels, trigger, dur, in, pan, envbufnum, maxGrains, mul, add)

numChannels - the number of channels to output. If 1, mono is returned and pan is ignored.

trigger - a kr or ar trigger to start a new grain. If ar, grains after the start of the synth are sample accurate.

The following args are polled at grain creation time

dur - size of the grain.

in - the input to granulate

pan -  Determines where to pan the output. If numChannels = 1, no panning is done. 

If numChannels = 2, panning is similar to Pan2.

if numChannels > 2, pannins is the same as PanAz.

envbufnum - the buffer number containing a singal to use for the grain envelope. -1 uses a built-in 

Hanning envelope.

maxGrains - the maximum number of overlapping grains that can be used at a given time. This value

is set at the UGens init time and can't be modified. Defaults to 512. This can be set lower for more

efficient use of memory.

*WARNING* The above parameter is new (post SC 3.3.1) and has the potential to break code written

<= 3.3.1. This parameter is BEFORE the mul slot, and you may need to update code to account

for this difference.

Examples:

s.boot;

(

var winenv;

// a custom envelope 

winenv = Env([0, 1, 0], [0.5, 0.5], [8, -8]);

z = Buffer.sendCollection(s, winenv.discretize, 1);

SynthDef(\in_grain_test, {arg gate = 1, amp = 1, envbuf;

var pan, env;

// use mouse x to control panning

pan = MouseX.kr(-1, 1);

env = EnvGen.kr(

Env([0, 1, 0], [1, 1], \sin, 1),

gate,

levelScale: amp,

doneAction: 2);

Out.ar(0,

GrainIn.ar(2, Impulse.kr(32), 1, PinkNoise.ar * 0.05, pan, envbuf) * env)

}).send(s);

)

// use built-in env

x = Synth(\in_grain_test, [\envbuf, -1])

// switch to the custom env

x.set(\envbuf, z)

x.set(\envbuf, -1);

x.set(\gate, 0);
