For those that haven't been following along, a TON of custom firmwares have shown up for the M-VAVE FM-1, a roughly ~$70 synth.

BaudGirl's VA is probably the biggest right now: https://baudgirl.com/work/FM-1+VA

But there's also https://github.com/hugelton/Felucca, https://github.com/charlesvestal/fm1-x0x, https://www.groove-os.com, https://isod89.github.io/sloop-fm1/webapp/installer/, and https://github.com/charlesvestal/fm1-fomni

AFAIK, all of them are vibecoded, but that doesn't mean they're not super fun.

Edit: Someone made a good firmware list: https://fm1-editor.com/firmware/
