   1 class:: Select
   2 summary:: Select output from an array of inputs.
   3 categories:: UGens>Multichannel>Select
   4
   5 Description::
   6 The output is selected from an array of inputs.
   7
   8 note:: All the UGens are continously running. This may not be the most efficient
   9 way if each input is CPU-expensive. ::
  10
  11 Note that the array is fixed at the time of writing the SynthDef, and the
  12 whole array is embedded in the SynthDef file itself.  For small arrays
  13 this is more efficient than reading from a buffer.
