@section{description}


note that there is a shortcut to create a Prout:


@racketblock[p(func)::

]
@section{ClassMethods}
 

@section{method}
 new
Returns a routine from the function.

@section{argument}
 routineFunc
routine function.

@section{Examples}
 


@racketblock[
(
var a;
a = Prout({ loop { 1.yield; 2.yield; 7.yield; 10.do { 1.0.rand.yield } }});
a.asStream.nextN(100).plot;
)


// sound example
(
SynthDef(\help_sinegrain,
	{ arg out=0, freq=440, sustain=0.05;
		var env;
		env = EnvGen.kr(Env.perc(0.01, sustain, 0.1), doneAction: Done.freeSelf);
		Out.ar(out, SinOsc.ar(freq, 0, env))
	}).add;
)


(
var a;
a = Prout({ loop { 1.yield; 2.yield; 7.yield; 10.do { 1.0.rand.yield } }}).asStream;
{
	a.do { |val|
		Synth(\help_sinegrain, [\freq, val * 100 + 300]);
		0.02.wait;
	}
}.fork;
)

// shortcut:
(

	\instrument, \help_sinegrain,
	\freq, p { loop { ([1000, 2000].choose + [100, 200].choose + [10, 20].choose).postln.yield } },
	\dur, 0.1
