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.

|
|

|
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.

|
|
code::
|

|
|
(

|
||
|
|
|

// write to the bus, crossfading with previous contents
|

|
|
a = Synth.tail(s, "help-XOut");
|
||
|
|
|
||
|
|
|
||
|
|
a.set(\xFade, 0.7);
