I've played with Bela [1] which uses the same real time kernel IIUC. It had super stable audio performance down to a 2 sample buffer, which felt like programming hardware. I'm very happy to see more work in this field.

Bela is fantastic because it pairs good audio hardware with low latency software. Elk looks good, but I'd need something better than a Raspberry Pi in terms of audio IOs to use that full potential.

There's a decent-looking hires 6in/6out hat on the site store, albeit "out of stock".

Bela is indeed fantastic, but the CPU is a bit weak.
