Oh, hang on, the Ux1 doesn’t have midi - it’s audio only.
Just read up on it though, you should be able to use the Moog effectively as a Midi interface with your computer. So the midi is over USB, but then the MIDI DIN sockets can patch up to the MIDI DIN sockets on your other equipment. You could then patch the audio outs from those devices through your Behringer mixer to your audio interface. Oooh, the possibilities!!!
