CoreMIDI

The wrapper of CoreMIDI Framework for Common Lisp

require:

please check version of dependency library.

install note:

It include objective-C file. because MIDIinput-handle callback is invoked from a separate C thread
It called foreign-thread callback.	Currently, It support ClozureCL only.
so in SBCL/ECL used wrapper objC-library for resolve that problem.
That objC library will build automatically when You load CoreMIDI lisp library.

package: midi

usage:

  • initialize load coremidi resources and initialize it.
  • list-of-sources print all midi sources in the system.
  • set-midi-callback register callback function for midi-input message from source(currently it supoort :note-on, :note-off, :cc, :bend).
  • list-of-destinations print all midi destinations in the system.
  • midi-send send midi message to destination

examples:

(ql:quickload :coremidi)

(midi:initialize)

(midi:set-midi-callback (midi:get-source 0) :note-on
		(lambda (chan note vel)
		  (format t "channel: ~d  notenum: ~d  velocity: ~d~%" chan note vel)))

(midi:midi-send (midi:get-destination 0) (+ (cb:now) 2) :note-on 1 60 100)
