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; });

argument::name
|
||
|
|
the key.
|
||
|
|
|
||
|
|
argument::value
|

can be a pattern or a stream. The resulting stream ends when that incoming stream ends.

argument::pattern
|
