MIDI Port number/name

[opmo 640]

To find out the midi ports setup of your system, please evaluate the (midi-destinations) function:

(midi-destinations)
=> ((0 . "Bus 1") (1 . "Bus 2") (2 . "Bus 3") (3 . "Bus 4")
    (4 . "Bus 5") (5 . "Bus 6") (6 . "Bus 7") (7 . "Bus 8")
    (8 . "Bus 9") (9 . "Bus 10") (10 . "Bus 11") (11 . "Bus 12")
    (12 . "Bus 13") (13 . "Bus 14") (14 . "Bus 15") (15 . "Bus 16")
    (16 . "Session 1") (17 . "Keyboard") (18 . "MIDI OUT") (19 . "UM-ONE"))

 

There are two possible ways to assign a port. One is with the port number and the other is with the port name (a string).

  (instrument
   :omn omn-form
   :port 0
   :channel 1
   :sound 'reaktor
   :program 1)

 

now with a string:

  (instrument
   :omn omn-form
   :port "Bus 1"
   :channel 1
   :sound 'reaktor
   :program 1
