TITLE:: InBus
summary::Return a range of channels from a bus, irrespective of node order
categories::UGens>InOut
related:: Classes/In, Classes/XIn, Classes/InFeedback, Classes/XInFeedback
DESCRIPTION::InBus provides a simple interface to the signal on a bus, crossfading between adjacent values.
code::
(
b = Bus.control(s, 9); // nine channel control rate
b.setn([244, 737, 20, 271, 382, 172, 4, 2399, 251]);
{
var index = MouseX.kr(0, 30);
Blip.ar(InBus.ar(b, 2, index, \wrap)) * 0.1
}.play;
)
::
CLASSMETHODS::
METHOD:: ar, kr
Return a new instance with the respective rate. If the bus rate doesn't match the signal is converted. Multi channel arguments expand.
ARGUMENT:: bus
An instance of link::Classes/Bus::
ARGUMENT:: numChannels
Number of output channels
ARGUMENT:: offset
Offset to the starting index in the bus.
ARGUMENT:: clip
If clip is set to 'wrap', the indices into the bus will not be clipped to the last bus channel, but will wrap around.
returns:: A UGen output, usually an array of UGens or, if the arguments are arrays, an array of arrays.
INSTANCEMETHODS::
EXAMPLES::
code::
(
s.waitForBoot({
b = Bus.control(s, 3);
b.setn([1, 10, 100]);
})
)
{ InBus.kr(b, 1, 0).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 1, 1).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 1, 2).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 1, 3).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 2, 0).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 3, 0).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 4, 0).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 3, 5).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 3, 5, \wrap).poll(2, "val"); 0.0 }.play;
InBus.kr(b, 2, [1, 3, 4]); // multi channel expansion
{ InBus.kr(b, 1, MouseX.kr(0, 10).round.poll(2, "index")).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 2, MouseX.kr(0, 10).round.poll(2, "index")).postln.poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 3, MouseX.kr(0, 10).round.poll(2, "index")).postln.poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 4, MouseX.kr(0, 10).round.poll(2, "index")).postln.poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 1, MouseX.kr(0, 10).round.poll(2, "index"), \wrap).poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 2, MouseX.kr(0, 10).round.poll(2, "index"), \wrap).postln.poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 3, MouseX.kr(0, 10).round.poll(2, "index"), \wrap).postln.poll(2, "val"); 0.0 }.play;
{ InBus.kr(b, 4, MouseX.kr(0, 10).round.poll(2, "index"), \wrap).postln.poll(2, "val"); 0.0 }.play;
