While I scour for a reasonably priced Zoom R24 for this I have managed to get a great deal on a Behringer U-PHORIA UMC404HD interface for me to get some more testing done with the Lattepanda.
This interface is an ideal candidate for this, as it features four XLR/Jack combination ins, four outs, input padding and phantom power for condenser mics; all the things I'd like.
While the interface lacks the ability to control a DAW physically I will be using a custom device from MakePro Audio as a substitute for now.
The control device contains a Raspberry Pi 4, and can communicate using OSC via wifi/ethernet and let me introduce four motorised faders and a smattering of buttons and encoders to use with my recording software.
If I can combine the two boards to work reliably together and also sit nicely in an enclosure/case I'll be tempted to crack on with this setup in all honesty.
