Ok, so I notice that my crossfader on the OT is sending (and responding to) CCs totally backwards. It still works as far as moving to the left makes sceneA audible and moving to the right makes sceneB audible, just the CC’s are backwards. So now cc value 0 selects sceneB and cc value 127 selects sceneA.
I tested the output of the OT in midiOX after I noticed the strange behaviour in reaper and confirmed.
I then reformatted my card and did an empty reset, but the crossfader is still backwards.
I was wondering if anyone has any suggestions for me to try before I fill out a support ticket.
