summary:: embed values in a list according to a pattern of indices

method::new
Pswitch1 chooses elements from the strong::list:: by a stream of indices ( strong::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.
Examples::
code::
(
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:2);
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;
)
