I recently installed my UR22 mk II and am having problems.
Cubase 9, windows 10, all latest drivers and firmware.
Whenever I am playing back any track, and have it panned hard L or hard R, I always have audio coming from both channels of the audio thru the headphones.
The input/daw is on DAW only.
Note, cubase is showing the audio playing mono out (see picture). But audio is definitely coming thru both channels of the UR22 headphone jack.
Seems that your ‘Stereo Out’ is setup as a mono output. I actually didn’t know that was possible, but check your selections for Stereo Out in VST Connections.
