[Octave-patch-tracker] [patch #9868] midi functions

[Lars Kindermann]

Follow-up Comment #7, patch #9868 (project octave):

Sending generated midi messages works ok now,
but re-transmitting received messages still fails:


pkg load midi

mididevinfo
devin  = mididevice ('input' ,'VMPK Output 128:0')
devout = mididevice ('output','FLUID Synth (10094) 130:0')

msg = midimsg("note", 0, 60, 127, 1.2)
midisend(devout, msg)

while 1 
 msg = midireceive(devin);
 if length(msg)
  msg 
  midisend(devout,msg)
 end 
endwhile

And how do I access the data?


>> msg.type
ans = NoteOn

>> msg.timestamp
ans = 0

>> msg.data
error: unimplemented midimsg.subsref property
