nextFunc - stream function

resetFunc - function that is called when the stream is reset.

// example

(

var a, x;

a = Pfunc({ exprand(0.1, 2.0) + #[1, 2, 3, 6].choose }, { \reset.postln });

x = a.asStream;

x.nextN(20).postln;

x.reset;

)

// sound example

(

SynthDef(\help_sinegrain,

{ arg out=0, freq=440, sustain=0.05;

var env;

env = EnvGen.kr(Env.perc(0.01, sustain, 0.2), doneAction:2);

Out.ar(out, SinOsc.ar(freq, 0, env))

}).memStore;

)

(

var a;

a = Pfunc({ exprand(0.1, 0.3) + #[1, 2, 3, 6, 7].choose }).asStream;

{

a.do { |val|

Synth(\help_sinegrain, [\freq, val * 100 + 300]);

0.02.wait;
