[Fluxus] commits: midi-out

[gabor papp]

hi all,

initial midi-out support is added to git. it breaks old midi code.
(midi-info) now returns outport ports also.
(midi-init) is replaced by (midiin-open) and (midiout-open). 
(midi-close) is replaced by (midiin-close) and (midiout-close).

the command that sends midi messages is (midi-send), which expects 1 to 
3 integers.

i haven't got any midi output device, so i only tested it briefly with 
virtual midi piano keyboard (http://vmpk.sourceforge.net/)

(require fluxus-017/fluxus-midi)

(displayln (midi-info))

(midiout-open 0)
(midi-send 144 64 90)
(sleep 1)
(midi-send 128 64 10)
(midiout-close)

best,
gabor
