I have used ofxmidi a fair bit but as far as I can tell it will not send midi show control messages (these are actually midi sysex messages I think they let you pick cues from many lighting desks among other things). Does anyone know how to send this kind of message.
not directly, but I seem to remember that there was a fix for that floating around somewhere. don’t know where, though. This (sending sysex) will be relevant for me, too, soon…
