class:: XOut
summary:: Send signal to a bus, crossfading with previous contents.
related:: Classes/OffsetOut, Classes/Out, Classes/ReplaceOut
categories:: UGens>InOut
Description::
Send signal to a bus, crossfading with previous contents.
code::xfade:: is a level for the crossfade between what
is on the bus and what you are sending. The algorithm is equivalent to this:
code::
bus_signal = (input_signal * xfade) + (bus_signal * (1 - xfade));
::
See the link::Reference/Server-Architecture:: and link::Classes/Bus:: helpfiles for more information on
buses and how they are used.
classmethods::
method::ar, kr
argument::bus
The index of the bus to write out to. The lowest numbers are written to the audio hardware.
argument::xfade
Crossfade level.
argument::channelsArray
An Array of channels or single output to write out. You cannot change the size of this once a SynthDef has been built.
Examples::
code::
(
SynthDef("help-SinOsc", { arg freq=440, out;
Out.ar(out, SinOsc.ar(freq, 0, 0.1))
}).add;
SynthDef("help-XOut", { arg out=0, xFade=1;
var source;
source = PinkNoise.ar(0.05);
// write to the bus, crossfading with previous contents
XOut.ar(out, xFade, source);
}).add;
)
Synth("help-SinOsc", [\freq, 500]);
a = Synth.tail(s, "help-XOut");
a.set(\xFade, 0.7);
a.set(\xFade, 0.4);
a.set(\xFade, 0.0);
