Pswitch

Pswitch(list, which)

chooses elements from the list by a stream of indices (which).

the elements are embedded in the stream, so if an element is a

pattern, it will play until it is finished. if it is a simple number it will

just yield itself.

play then resumes embedding the next element in the list...

(

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:2);

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

}).send(s);

)

(

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;

})

}).play;
