Examples

(
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))
    }).add;
)

(
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;
    }
}.fork;
