class:: Pset
summary:: event pattern that sets values of one key
related:: Classes/Pbindf, Classes/Psetp
categories:: Streams-Patterns-Events>Patterns>Filter
description::
Pset sets a value in an event stream. It acts like one key in a link::Classes/Pbindf::.
code::
(
var a, b;
a = Pset(\freq, 801, Pbind(\dur, 0.5));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)
::
ClassMethods::
method::new
argument::name
the key.
argument::value
can be a pattern or a stream. The resulting stream ends when that incoming stream ends.
argument::pattern
the pattern.
Examples::
code::
//Pset overrides incoming values:
(
var a, b;
a = Pset(\freq, 801, Pbind(\freq, 108));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)
(
var a, b;
a = Pset(\freq, Pseq([401, 801], 2), Pbind(\dur, 0.5));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)
//sound example
(
SynthDef(\sinegrain,
{ arg out=0, freq=440, sustain=0.02;
var env;
env = EnvGen.kr(Env.perc(0.001, sustain), 1, doneAction: Done.freeSelf);
Out.ar(out, SinOsc.ar(freq, 0, env * 0.1))
}).add;
)
(
a = Pbind(\dur, 0.5, \instrument, \sinegrain);
a = Pset(\freq, Pseq([500, 600, 700], inf), a);
a = Pset(\legato, Pseq([0.01, 1],inf), a);
a.play;
)
