Pswitch 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 first completely embeds it before looking for the next index.
|
|
|
|
Examples::
|
|
|
|
code::
|
|
(
|
|
var a, b;
|
|
a = Pseq([1, 2, 3], 2);
|
|
b = Pseq([65, 76]);
|
|
c = Pswitch([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], 2);
|
|
b = Pseq([0, 0, 0, 4, 0]+64);
|
|
c = Pswitch([a, b, 75], Pseq([2, 2, 0, 1], inf));
|
|
x = c.asStream;
|
|
Routine({
|
|
loop({
|
|
Synth(\help_sinegrain, [\freq, x.next.midicps]);

0.18.wait;
