DJM 750 MK2 recording issue on macOS Monterey


Running macOS 12.3.1 with a DJM 750 MK2 driver version 4.0.0.

I've been having an issue with recording and it's been happening whilst recording in any application. I've tried recording in RekordBox, Ableton, and also Audacity. The issue happens the exact same in each.

Basically, the audio will be recording fine for a while, and then usually after 45-60 min or so, it's like the recording level becomes extremly high and the aduio is totally distorted. 

I've tried uninstalling and reinstalling the driver and checked to verify that Monterey is supported. As mentioned, it doesn't matter which app I use for recording, the issue is the same. Doesn't happen every time, but 80-90% of the time it does. I'm not using the Mac for anything other than recording. I've also tried using a different USB cable (just in case) but no change.


Any suggestions would be great. In the meantime, I've gone back to using an old Behringer sound card on the booth output which has been fine but I would prefer to use the internal 750 mk2's sound card for best quality.

Just to add, the issue doesn't just happen when I listen back to the recording. I can hear the issue if monitoring the input in Ableton for example. The issue has only started since upgrading to Monterey.
