Issue using endless knobs with C6 commands... [SOLVED !]

OK this won’t work because relative only works for NoteOn message and not NRPNs.
I think you’ll have to use a different approach :frowning:
That being:

  1. Using the controllers as normal CCs from 0 to 127, and enabling Soft Takeover in Cubase.
  2. Use a programmatic approach to convert the NRPN inc/dec to NoteOn with 1 and 127 (Midi-ox might do that).
  3. Use a programmatic approach to store current values receive from Cubase and send the correct values upstream.

Before we’re done, I’d like you to check whether the MPD32 can receive values from Cubase, if it can, it can solve our whole mess.
Set the MPD to CC mode, simple 0 to 127, and the same in Cubase.
Set the values as Receive and Transmit.
Change a value in Cubase. Did the value change in the MPD?
Change a value in the MPD, did it jump or did it continue from the correct spot?
