class:: Pfinval
summary:: limit number of items embedded in a stream
related:: Classes/Pfindur, Classes/Pfin, Classes/Pconst
categories:: Streams-Patterns-Events>Patterns>Repetition
description::
note::
Pfinval is not appropriate for wrapping link::Classes/Pmono::, link::Classes/Pfx:: etc. For these types of event patterns, you should use link::Classes/Pfin::.
::
ClassMethods::
method::new
Embeds strong::count:: elements of the strong::pattern:: into the stream.
Examples::
code::
(
var a, b;
a = Pfinval(5, Pseq(#[1, 2, 3],inf));
b = a.asStream;
9.do({ b.next.postln; });
)
//Pfinval used as 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;
)
(
var c, b;
c = Pn(Pfinval({ rrand(3, 5)}, Pseq([1, 2, 3, 4, 5, 6],inf)*4+65),inf);
b = c.asStream;
Routine({
loop({
Synth(\help_sinegrain, [\freq, b.next.midicps]);
