Has anyone figured out how to use the little directional and other buttons on the top of the M-Audio keyboard to send MIDI messages to Hauptwerk? They don't even register in Midi-OX.
If they don't register in Midi-ox, then they can't be used in Hauptwerk. The hardware uses it for its own purposes, but those buttons don't broadcast a midi signal.
I have a Cakewalk A-500PRO. The keyboard comes with a mapping editor where you can define the midi messages yourself. But I don't need it because most of the keys and controls send a midi message. Perhaps there is also an editor for your keyboard.
