This is obviously not the first time someone has asked about this, but I'm having the exact same issue and I have yet to see an explanation for how to fix it. I also have yet to find the user manual if someone is able to point me in the right direction...
Both of my keyboards are going through the same MIDI channel, even though my lower manual is set at MIDI 1 and my upper manual is set at MIDI. I can have both keyboards going through both channels, or both keyboards going through just one channel but I can't split them up so that they each go to a different channel. What should I be doing differently?
and what does the Program Change setting do? Would that make a difference?
They are both plugged through USB:
Lower manual -- Roland RD 2000
Drawbars controlled through onboard faders.
Upper manual -- Yamaha NP12
Drawbars controlled through outboard AKAI MidiMix
L & R Output -- Steinberg UR44C
Thank you in advance.
