class:: Plazy
summary:: instantiate new patterns from a function
related:: Classes/PlazyEnvir, Classes/PlazyEnvirN, Classes/Pfunc
categories:: Streams-Patterns-Events>Patterns>Function
description::
Plazy evaluates a function that returns a pattern and embeds it in a stream.
ClassMethods::
method::new
argument::func
A link::Classes/Function:: that returns a pattern or any other valid pattern input.
Examples::
code::
(
a = Plazy({
var x, y;
x = Array.series(rrand(2, 4), [1, 100].choose, 1);
Pshuf(x,1);
});
x = Pn(a, inf).asStream;
30.do({ x.next.postln });
)
//Plazy used to produce 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: Done.freeSelf);
Out.ar(out, SinOsc.ar(freq, 0, env))
}).add;
)
(
a = Plazy({
var x, y;
x = Array.series(rrand(2, 4), [1, 5].choose, 1);
x.put(x.size.rand, 8+0.1.rand2);
Pseq(x,1);
});
x = Pn(a, inf).asStream;
Routine({
loop({
Synth(\help_sinegrain, [\freq, (x.next*5+70).midicps]);
0.13.wait;
})
}).play;
)
// using event streams
(
a = Plazy({
var x, y;
x = Array.series(rrand(2, 4), [1, 5].choose, 1);
x.put(x.size.rand, 8+0.1.rand2);
Pbind(
\instrument, \help_sinegrain,
\dur, 0.12,
\degree, Pseq(x, 2)
)
});
Pn(a, inf).play;
)
