• cc (opdef):  – `num` from cc-change messages.

  (midi/cc [port] cc [range] [chan])

  range can be one of:

  • ‘raw’ [ 0 - 128[
  • ‘uni’ [ 0 - 1[ (default)
  • ‘bip’ [-1 - 1[
  • ‘rad’ [ 0 - tau[
  • ‘deg’ [ 0 - 360[
  • (num) [ 0 - num[
• gate (opdef):  – gate from note-on and note-off messages.

  (midi/gate [port] note [chan])

• input (opdef):  – Create a MIDI input port.

  (midi/input name [port])

• output (opdef):  – Create a MIDI output port.

  (midi/output name [port])

• port (opdef):  – Create a bidirectional MIDI port.

  (midi/port name [in] [out])

• port-names (opdef):  – Get all MIDI port names.

  (midi/port-names direction)
