class:: Pmul
summary:: multiply with value of a key in event stream
related:: Classes/Padd, Classes/Pmulp
categories:: Streams-Patterns-Events>Patterns>Math
ClassMethods::
method::new
argument::value
can be a pattern or a stream. The resulting stream ends when that incoming stream ends.
Examples::
code::
(
var a, b;
a = Pmul(\freq, 801, Pbind(\freq, 100));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)
::
code::
(
var a, b;
a = Pmul(\freq, Pseq([3, 4, 6], 2), Pbind(\freq, 100));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)

code::
//sound example
(
SynthDef(\sinegrain,
{ arg out=0, freq=440, gate=1;
var env;
env = EnvGen.kr(Env.asr(0.001, 1, 0.2), gate, doneAction:2);
Out.ar(out, SinOsc.ar(freq, 0, env * 0.1))
}).add;
)
(
a = Pbind(\dur, 0.5, \instrument, \sinegrain, \freq, 440);
