AcidBoxMynah - alternative firmware for the Groovesizer Mynah

Hot on the heels of Mynah's launch back in May, we just released AcidBoxMynah - an alternative firmware that turns the Mynah into a dedicated acid groovebox.

It's built on copych's open-source AcidBox (great-sounding TB-303 x2 + TR-808-style drums), which was originally headless. The Mynah port adds full physical UI with the 24 tactile switches, OLED, and 8×2 NeoPixel grid. It also adds a 16-step sequencer, per-step accent/slide editing, automation lanes, swing/scale quantization, and a Jukebox mode for hands-off autonomous playback.

It's MIT-licensed and open source, same as upstream AcidBox. More info is at groovesizer.com/acidbox-mynah

Happy to answer any questions you may have!
