Ppatmod


superclass: Pattern



the function that modifies the enclosed pattern and embeds it in the stream.


Ppatmod(pattern, func, repeats)



 

(

a = Ppatmod(

Pseq([0, 0, 0, 0],1),

{ arg pat, i;

var list;

list = pat.list;

pat.list = list.put(list.size.rand, 2);

}, inf);


x = a.asStream;

30.do({ x.next.postln });

)



Ppatmod used to modify a pattern that produces a sequence of pitches:

 

(

SynthDef("help-sinegrain", 

{ arg out=0, freq=440, sustain=0.05;

var env;

env = EnvGen.kr(Env.perc(0.01, sustain, 0.2), doneAction:2);

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

}).send(s);

)



(

a = Pn(

Ppatmod(

Pseq([0, 0, 0, 0],1),

{ arg pat, i;

var list;

list = pat.list;

pat.list = list.put(list.size.rand, 2);

}, 15),

inf).asStream;


Routine({

loop({

Synth("help-sinegrain", [\freq, (a.next*5+77).midicps]);

0.13.wait;

})

}).play;

)
