资源说明：A high level midi library to play notes and interact with external midi devices.
midi-clj
==============
#### A streamlined midi API for Clojure
midi-clj is being developed for Project Overtone, and it is meant to simplify
the usage of midi devices and the midi system from within Clojure.
(use 'midi)
; Select midi input and output devices
; These functions bring up a GUI chooser window to select a midi port
(def keyboard (midi-in))
(def phat-synth (midi-out))
; Once you know the correct device names for your devices you can save the
; step of opening up the GUI chooser by putting a unique part of the name
; as an argument to midi-in or midi-out. The first device with a name that
; matches with lookup is returned.
(def ax (midi-in "axiom"))
; Connect ins and outs easily
(midi-route keyboard phat-synth)
; Trigger a note (note 40, velocity 100)
(midi-note-on phat-synth 40 100)
(Thread/sleep 500)
(midi-note-off phat-synth 0)
; Or the short-hand version to start and stop a note
(midi-note phat-synth 40 100 500)
; And the same thing with a sequence of notes
(midi-play phat-synth [40 47 40] [80 50 110] [250 500 250])
In Ubuntu Linux I use the snd-virmidi kernel module to provide software midi
ports. USB midi devices should be pretty much plug and play.
