Yeah, I would love to see a CircuitPython powered module that has even just one CV/gate input. I’ve been looking at the Daisy Patch but it doesn’t support anything nearly as simple as the CircuitPython platform, which makes me hesitant to spend a lot of time developing for it as distributing firmwares is a bit of a pain.
I’m quite tempted to throw something together with a Teensy 4.1, which has more than enough power for a decent DSP platform as well as supporting MIDI, CAN, and CircuitPython, and has an SD card slot, but I don’t think I could realistically do manufacturing and distro.
That said, I am currently looking at a building a guerilla expander for the Sol which gives at least a clock in, so I can more easily send MIDI clock from my Pam’s.
