I have done several reinstalls to no avail. I note that in System Devices - USB Devices there is only an IAD File and there is no DFU. Keyboard is light up and I can scroll through presets using Komplet Kontrol. My DAW is not recognizing my keyboard. Bottom line there is no MIDI either in or out. Lets hope I am doing something stupid here rather than it being something major. Any help appreciated.
