Pfindur limit total duration of events embedded in a stream

superclass: FilterPattern

Pfindur(dur, pattern, tolerance)

embeds elements of the pattern into the stream until the duration comes close enough to dur.

(

var a, b;

a = Pfindur(5, Pbind(\dur, Prand([1, 2, 0.5, 0.1], inf)));

x = a.asStream;

9.do({ x.next(Event.default).postln; });

)

Pfindur used as a sequence of pitches
