Pfset create an environment to modify values in the incoming stream

superclass: FuncFilterPattern

Pfset(name, value, pattern)

(

var a, b;

a = Pfset({

~legato = 0.3;

~detune = rrand(0, 30);

}, Pbind(\dur, 0.5));

x = a.asStream;

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

)

Pfset does not override incoming values:

(

var a, b;

a = Pfset({

~dur = 0.3;

}, Pbind(\dur, 0.5));

x = a.asStream;

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

)

sound example

(

SynthDef(\sinegrain, 

{ arg out=0, freq=440, sustain=0.02;

var env;

env = EnvGen.kr(Env.perc(0.001, sustain), 1, doneAction:2);

Out.ar(out, SinOsc.ar(freq, 0, env * 0.1))

}).store;

)

(

a = Pbind(\dur, 0.5, \instrument, \sinegrain, \x, Pfunc { rrand(500, 600) });

a = Pfset({ ~freq = { ~x.postln * 2 }; ~legato = 3; },  a);

a.play;

)
