I have the Oxygen 49 controller and Kontakt (standalone) sees it - but it's set to OFF under Settings > MIDI and I can't turn it on. Anyone know why?
 
The options are Port A, B, C, and D, but no matter what I select, it doesn't change and the keyboard makes no sound. Was working fine earlier!
 
Thanks - rev

Solved: I accidentally had two instances of Kontakt open and that was preventing me from changing the setting.
