alt Hacker NewsThe copy makes it pretty clear this is firmware for a CM5.
Rest assured, if you click the "READ THE MANUAL" button on the landing page you will see screenshots of all synth engines and configuration screens.
The repo's README also starts with a screenshot.
Thanks.
To be fair, it doesn't seem to be mentioning this until the "Purpose-built on Compute Module 5" section which is more than halfway through the entire landing page, I was similarly lost until I got to that section and actually understood what I was looking at :)
Looks really fleshed out and fun though, now I just need to get my hands on a proper carrier board it seems, as the audio out of the box for standard CM5 development I/O board is kind of horrible.
