Pswitch1 embed values in a list according to a pattern of indices

Pswitch1(list, which)

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));

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:2);

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

}).send(s);

)

(

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;
