class:: Pindex
summary:: pattern that indexes into an array
related:: Classes/Pswitch
categories:: Streams-Patterns-Events>Patterns>List>Indexing
description::
This allows an link::Classes/ArrayedCollection:: to be accessed within patterns.
ClassMethods::
method::new
argument::listPat
the array. Can be a link::Classes/Pattern::.
argument::indexPat
the value to retrieve. Can be a link::Classes/Pattern::.
argument::repeats
specifies the number of repeats.
Examples::
code::
(
SynthDef(\help_pindex, { | out, amp=0.1, freq=440, gate=1 |
var son = Saw.ar(freq * [0.99, 1, 1.01]).mean;
son = son * EnvGen.ar(Env.adsr, gate: gate, doneAction: Done.freeSelf);
Out.ar(out, son.dup * amp);
}).add;
)
(
var data = [7, 13, 12, 2, 2, 2, 5];
var indices = [0, 0, 2, 0, 4, 6, 7];
Pbind(
\instrument, \help_pindex,
\choice, Prand(indices, inf),
\degree, Pindex(data, Pkey(\choice), inf),
\dur, 0.7
