I presume you’re talking about using the custom layer for MIDI/DAW Control?
In which case, there should be no issue with the USB connection for audio and MIDI as this is class compliant.
A&H MIDI Control is not officially supported on Monterey (please let me know if you’ve read otherwise) but saying that, we’re also not aware of any issues with it.
I’d suggest trying a fresh reinstall of A&H MIDI Control and a check of the setup.
Also double check what is assigned on the custom layer.
You can then see if there’s messages coming in from the Qu and move on to checking the setup in the DAW (based on the MIDI Control help doc).
If you’re still having issues, please contact us using support.allen-heath.com and we’ll be able to go into more detail with you.

Cheers,
