class:: Psubdivide
summary:: partition a value into n equal subdivisions
related:: Classes/Pdup
categories:: Streams-Patterns-Events>Patterns>Repetition
description::
A filter pattern designed for a stream of float durations.
Subdivides each duration by each subdivision and yields that value n times. A subdivision of 0 will skip the duration value, a subdivision of 1 yields the duration value unaffected.
Examples::
code::
(
a = Psubdivide(
Pseq(#[1,1,1,1,1,2,2,2,2,2,0,1,3,4,0],inf),
Pseq(#[0.5, 1, 2, 0.25,0.25],inf)
);
x = a.asStream;
100.do({ x.next.postln; });
)
(
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 = Psubdivide(
Pseq(#[1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4],inf),
Pseq(#[0.5, 1, 2, 0.25,0.25],inf)
);
x = a.asStream;
Routine({
loop({
Synth.grain(\help_sinegrain, [\freq, 440]);
x.next.wait;
})
}).play(TempoClock.default);
)
(
a = Psubdivide(
Pseq(#[1,1,1,1,1,2,2,2,2,2,3,3,3,3,4,4,0,4,4],inf),
Pseq(#[0.5, 1, 2, 0.25,0.25],inf)
);
x = a.asStream;
Routine({
loop({
Synth.grain(\help_sinegrain, [\freq, 440]);
x.next.wait;
})
}).play(TempoClock.default);
)
::
Frequencies like being divided too.
code::
(
a = Psubdivide(
Pseq(#[1,1,1,1,1,2,2,2,2,2,3,3,3,3,4,4,0,4,4],inf),
Pseq((80 + [ 0, 2, 3, 5, 7, 9, 10 ]).midicps ,inf)
);
x = a.asStream;
Routine({
loop({
Synth.grain(\help_sinegrain, [\freq, x.next.postln]);
0.25.wait
})
}).play(TempoClock.default);
)
