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::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::
(
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; });
