IOhannes,
david,miller: i don't think that the suggested solution [247, NN, NN, 240( will actually work (but i haven't tested, of course) because of the non-existing raw-midi: instead all of your bytes will be encapsulated into separate sysex packages, which is kind of dumb... (at least this is what kmidimon tells me when intercepting the outgoing midi-stream)
Do you mean that you can send messages eliminating F7 and F0 to let the API compensate for it?
So far I haven't been able to get kmidimon routed through qjackctl + Alsa-MIDI to respond to anything sent to [midiout].
I did locate your post regarding the mentioned behavior (Thanks to Hans for pointing me)
Can you please tell me if you've done anything special to at least get it recognized by kmidimon?
