I try to change the "0V MIDI Note reference" in the Midi Control Center (see English manual: 9.10.4.2. MIDI Note reference (0V, 1V), p.95), but is does not change.
When I change the value in MCC, I don't see the upload symbol (orange arrow up flashing once) like it is shown when I change other values. I could find any solution, so maybe someone has an idea how to solve this issue?
