Ptuple
superclass: ListPatterns
Ptuple(list, repeats)
list: an Array of Patterns
repeats: an Integer or inf
At each iteration returns a tuple (array) combining the output of each of the patterns in the list. When any of the patterns returns a nil, Ptuple ends that 'repeat' and restarts all of the streams.
(
var a, b;
a = Pseq(#[1, 2, 3], inf);
b = Pseq(#[65, 76], inf);
c = Ptuple([a, a, b], inf);
x = c.asStream;
8.do({ x.next.postln; });
)
(
var a, b;
a = Pseq(#[1, 2, 3], inf);
b = Pseq(#[65, 76], 3); // stops after 3 cycles
c = Ptuple([a, a, b], 4); // stops after 4 cycles
x = c.asStream;
8.do({ x.next.postln; });
)
Ptuple used as a sequence of pitches (chords)
