Cubase switching Devices during recording


New member
In Cubase AI 10.5 I have the Yamaha Steinberg USB driver with two Devices: UR22 audio/MIDI and Yamaha MX synth USB interfaces. Cubase has started defaulting to the MX device during recording and playback. I have to stop Cubase and reset it to the UR22. Why is it doing this and how can I stop it?
