Hi, had keyboard for a few years but not had a massive amount of use. I am not getting any midi out through USB for keys, mod wheel and pitch bend. Komplete kontrol software works fine and mixi ox detects midi out from the kontrols but again not keys, mod or pitch bend. I've tried usb cable with my m32 controller and that's fine. I feel the usb port may be broken. Its not loose and has had no damage but I can half pull out the cable and get usb disconnected audio warning but keyboard is still powered. Very disappointing as had little use over the years. Any thoughts as I am about to whip off the cover to see if the port looks dodgy?
