Out write a signal to a bus


superclass:  AbstractOut


*ar(bus, channelsArray)  - write a signal to an audio bus.

*kr(bus, channelsArray)  - write a signal to a control bus.

bus - the index of the bus to write out to. The lowest numbers are written to the audio hardware.

channelsArray - an Array of channels or single output to write out. You cannot change the size of this once a SynthDef has been built.


N.B. Out is subject to control rate jitter. Where sample accurate output is needed, use OffsetOut.

Note that using the Bus class to allocate a multichannel bus simply reserves a series of adjacent bus indices with the Server object's bus allocators. abus.index simply returns the first of those indices. When using a Bus with an In or Out ugen there is nothing to stop you from reading to or writing from a larger range, or from hardcoding to a bus that has been allocated. You are responsible for making sure that the number of channels match and that there are no conflicts.


See the Server-Architecture and Bus helpfiles for more information on buses and how they are used.
