repeat input stream values
Subclasses: PdurStutter

Description

repeat each element n times.

(
var a, b;
a = Pstutter(2, Pwhite(-1.0, 1.0));
x = a.asStream;
8.do { x.next.postln };
)

This is also a response to Pattern: -stutter

Class Methods

Pstutter.new(n, pattern)

Arguments:

n

The number of repeats for each new element. n may be a pattern, so the number of times can vary each iteration.

pattern

the pattern to repeat.

Examples

// the first argument can be a pattern, too:
(
var a, b;
a = Pstutter(Prand([1, 2, 5], inf), Pwhite(-1.0, 1.0)); // repeat either once, twice, or five times
x = a.asStream;
20.do { x.next.postln };
)

// using event patterns:
(
SynthDef(\help_sinegrain,
    { | out=0, freq=440, sustain=0.05 |
        var env;
        env = Env.perc(0.01, sustain, 0.2).kr(doneAction: Done.freeSelf);
        Out.ar(out, SinOsc.ar(freq, 0.5pi, env))
    }).add;
)

(
a = Pbind(
    \instrument, \help_sinegrain,
    \note, Pxrand([0, 5, 7, 9], inf),
    \dur, 0.05,
    \sustain, 0.1
);
Pstutter(Pseq([1, 2, 3, 4], inf), a).trace.play;
)


// Pstutter used as a sequence of pitches

(

    loop {
