FMGrain granular synthesis with FM grains

 *ar(trigger, dur, carfreq, modfreq, index, mul, add) 

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.

carfreq - the carrier freq of the grain generators internal oscillator

modfreq - the modulating freq of the grain generators internal oscillator

index - the index of modulation

Examples:

s.boot;

SynthDef(\fm_grain_test, {arg gate = 1, amp = 1;

Out.ar(0,

FMGrain.ar(Impulse.ar(20), 0.2, 440, 200, 

LFNoise1.kr(1).range(1, 10),

EnvGen.kr(

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

gate,

levelScale: amp,

doneAction: 2)

)

)

}).load(s);

s.sendMsg(\s_new, \fm_grain_test, a=s.nextNodeID, 0, 1, \amp, 0.1);

s.sendMsg(\n_set, a, \gate, 0);
