X-Keys are the last thing and hopefully this makes sense to someone - I'm going to try to reprogram the x keys again and calling x-keys themselves, but I ran a MIDI diagnostic file for Martin, just pressing two of the x keys, 15 seconds apart. I had them assigned to two different letters, z & x, and evidenced by using the x-keys in notepad, you see both each letter come up correctly when pressing each key. But both are sending the same letter to Hauptwerk though? z ?
Thanks, Brian.
I can see from your diagnostic file that both keys are actually sending the same key code to the computer:
2018-06-29-07-19-54: INF:2557 Diag: IN: computer key pressed: hex key code: 0000005A.
2018-06-29-07-20-10: INF:2557 Diag: IN: computer key pressed: hex key code: 0000005A.
Key code 5A is the letter 'Z'.
That must be due to the way they're configured in the X-Keys software, but I can't help with that, I'm afraid. Hopefully an X-Keys user on the forum will be able to help you (or perhaps you could contact the makers of the X-Keys unit for support if needed).
