embed values in a list according to a pattern of indices

Source: ListPatterns.sc

From superclass: Pswitch

Pswitch1 chooses elements from the **list** by a stream of indices ( **which** ) and embeds them in the stream. If the element is itself a pattern, it embeds only one of its values for each index, and thus switches between all patterns in the list.

( var a, b; a = Pseq([1, 2, 3], inf); b = Pseq([65, 76], inf); c = Pswitch1([a, b, 800], Pseq([2, 2, 0, 1], inf)); x = c.asStream; 24.do({ x.next.postln; }); ) //Pswitch 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: Done.freeSelf); Out.ar(out, SinOsc.ar(freq, 0, env)) }).add; ) ( a = Pseq([73, 71, 69], inf); b = Pseq([0, 0, 0, 4, 0]+64, inf); c = Pswitch1([a, b, 75], Pseq([2, 2, 0, 1], inf)); x = c.asStream; Routine({ loop({ Synth(\help_sinegrain, [\freq, x.next.midicps]); 0.18.wait; }) }).play; )
