I can't see the code for the sending of midi note on and off messages, but tests seems to show they only send on channel 1. Can the channel be specified? Where is the code for these functions BTW?
the Overtone MIDI library was extracted a while back. The code is here: https://github.com/overtone/midi-clj/ and yes, the channel may be specified :-)
any joy specifying channels?
As far as I'm aware, specifying channels is currently implemented for note-on and note-off. Please re-open if found not to be the case.
