class:: SplayAz
summary:: Spreads an array of channels across a ring of channels
categories:: UGens>Multichannel>Panners
related:: Classes/Splay, Classes/SplayZ
description::
SplayAz spreads an array of channels across a ring of channels.
Optional spread and center controls, and levelComp(ensation) (equal power).
numChans and orientation are as in link::Classes/PanAz::.

code::
(

SplayAz.ar(
4,
SinOsc.ar( { |i| LFNoise2.kr( rrand(10, 20), 200, i + 3 * 100) } ! 10),
spread,
level,
width,
center
);
}.scope;
)
x.set(\spread, 1, \center, 0); // full n chans
x.set(\spread, 0.5, \center, -0.25); // less wide
x.set(\spread, 0, \center, 0); // mono center (depends on orientation, see PanAz)
x.set(\spread, 0, \center, -0.25); //
x.set(\spread, 0.0, \center, 0.5); // mono, but rotate 1 toward the higher channels
x.set(\spread, 0.5, \center, 0.5); // spread over the higher channels
x.set(\spread, 0, \center, -0.25); // all on first channel
x.set(\spread, 1, \center, 0); // full n chans
x.free;
// the same example written with arFill:
(
x = { arg spread=1, level=0.5, width=2, center=0.0;
SplayAz.arFill(
4,
10,
{ |i| SinOsc.ar( LFNoise2.kr( rrand(10, 20), 200, i + 3 * 100) ) },
spread,
level,
width,
center
);
}.scope;
)
// or with mouse control
(
x = { var src;
src = SinOsc.ar( { |i| LFNoise2.kr( rrand(10, 20), 200, i * 100 + 400) } ! 10);
SplayAz.ar(4, src, MouseY.kr(1, 0), 0.2, center: MouseX.kr(-1, 1));
}.scope;
)
// test for correct behavior:
// only on chan 0
{ SplayAz.ar(4, SinOsc.ar * 0.2, orientation: 0) }.scope;
// on chan 0, 3, i.e. equally around the ring
{ SplayAz.ar(6, SinOsc.ar([2, 3] * 200) * 0.2, orientation: 0) }.scope;
// equal spread on 0, 2, 4
{ SplayAz.ar(6, SinOsc.ar([2, 3, 5] * 200) * 0.2, orientation: 0) }.scope;
// wrong behavior of SplayZ:
// plays on chan 2, but should play on 0
{ SplayZ.ar(4, SinOsc.ar * 0.2, orientation: 0) }.scope;
// wrong: mixes both to chan 2,
// because pan values [-1, 1] are the same pos on the ring
{ SplayZ.ar(6, SinOsc.ar([2, 3] * 200) * 0.2, orientation: 0) }.scope;
// wrong equal spread to pan values [-1, 0, 1], which outputs to chans 2, 0, 2
{ SplayZ.ar(6, SinOsc.ar([2, 3, 5] * 200) * 0.2, orientation: 0) }.scope;
