The output is selected from an array of inputs.

@section{note}
|
||
|
|
All the UGens are continuously running. This may not be the most efficient
|
||
|
|
way if each input is CPU-expensive. ::
|
||
|
|
|
||
|
|
Note that the array is fixed at the time of writing the SynthDef, and the
|
||
|
|
whole array is embedded in the SynthDef file itself. For small arrays
|
||
|
|
this is more efficient than reading from a buffer.
