Trouble recording with DJM 750 MK2 via Rekordbox on Mac

Hi guys,

Having issues recording via Rekordbox.

I've got 2x XDJ700 and a DJM 750MK2 mixer and a Mac with latest update of Catalina 10.15.1 (and latest driver updates for the mixer installed with security permissions allowed)

The Mixer is connected via USB to the mac and rekordbox recognises that the mixer is connected, Audio input on Rekordbox is selected as the DJM mixer.

Everything seems to be set up as normal for recording, but it does not seem to be receiving any audio. I've racked my brain over this for some time and checked everything I can think of but I'm not getting any further.

Any help is appreciated as I would really like to get recording asap!

Thank in advance
