OK… just setted again the Outputs to only “Out to MIDI Yoke : 1”. The result is that I no longer get messages in the Monitor Outputs window… Again, what is the ‘MIDI Mapper’, actually ?
I also checked in Cubase, and there is no MIDI Yoke port, whether in the MIDI ports category of the ‘Device setup’ window or in the ‘MIDI Input’ list of the Generic Remote definition… Cubase seems to ignore anything MIDI-OX related : it continues to record all the NRPN incr/decr messages as if MIDI-OX wasn’t even running.
