method::new

argument::name

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

Examples::

code::
(
var a, b;
a = Padd(\freq, 801, Pbind(\freq, 100));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
)
::

code::
(
var a, b;
a = Padd(\freq, Pseq([401, 801], 2), Pbind(\freq, 100));
x = a.asStream;
9.do({ x.next(Event.new).postln; });
