Pseq : ListPattern : Pattern : AbstractFunction : Object

Description

Cycles over a list of values. The repeats variable gives the number of times to repeat the entire list.

Examples

(

var a, b;

a = Pseq([1, 2, 3], 2);    // repeat twice

b = a.asStream;

7.do({ b.next.postln; });

)

Pseq also has an offset argument which gives a starting offset into the list.( var a, b; a = Pseq([1, 2, 3, 4], 3, 2); // repeat 3, offset 2 b = a.asStream; 13.do({ b.next.postln; }); )

xxxxxxxxxx

(

var a, b;

a = Pseq([1, 2, 3, 4], 3, 2);    // repeat 3, offset 2

b = a.asStream;

13.do({ b.next.postln; });

)

You can pass a function for the repeats variable that gets evaluated when the stream is created.( var a, b; a = Pseq([1, 2], { rrand(1, 3) }); // repeat 1,2, or 3 times b = a.asStream; 7.do({ b.next.postln; }); )

xxxxxxxxxx

(

var a, b;

a = Pseq([1, 2], { rrand(1, 3) });    // repeat 1,2, or 3 times

b = a.asStream;

7.do({ b.next.postln; });

)

If you specify the value inf for the repeats variable, then it will repeat indefinitely.( var a, b; a = Pseq([1, 2, 3], inf); // infinite repeat b = a.asStream; 10.do({ b.next.postln; }); )

xxxxxxxxxx

(

var a, b;

a = Pseq([1, 2, 3], inf);    // infinite repeat

b = a.asStream;

10.do({ b.next.postln; });

)

Pseq 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(#[60, 61, 63, 65, 72], inf).asStream; Routine({ loop({ Synth(\help_sinegrain, [\freq, a.next.midicps]); 0.2.wait; }) }).play; )

(

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(#[60, 61, 63, 65, 72], inf).asStream;

Routine({

    loop({

        Synth(\help_sinegrain, [\freq, a.next.midicps]);
