*midi-channel-map*

[Variable]
  `*midi-channel-map*`

A default MIDI channel map used by subclasses of `midi-stream` if a map is not specified when the stream is created. A channel map is a list or vector of logical channel defininitions. Each definition in the map is a two-element list: (port channel) that specifies the integer port id and integer channel number of the logical channel defined by that position. The default channel map defined by CM provides 64 logical channels using four ports (0-3) and 16 channels (0-15) per port.
