Prand
superclass: ListPatterns
returns one item from the list at random for each repeat.
(
var a, b;
a = Prand.new(#[1, 2, 3, 4, 5], 6); // return 6 items
b = a.asStream;
7.do({ b.next.postln; });
)
Prand used as a sequence of pitches:
(
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))
}).send(s);
)
(
a = Prand(#[60, 61, 63, 65, 72], inf).asStream;
Routine({
loop({
Synth("help-sinegrain", [\freq, a.next.midicps]);
0.2.wait;
})
}).play;
)
