X0X-RMX for the FM-1

Groovebox firmware for the M-VAVE FM-1. A 909, an 808, two 303s with the TB-3PO line generator, and a breakbeat player, all running at once, with patterns, a song mode and recorded knob moves. This independent fork adds Orb-inspired Remix for 909, 808, 303A and 303B, Grids MAP/EUCLID drum generation with NEW/MUTATE, FILL, OFFSET, CHAOS and Undo, extended TB-3PO, a 303 Morph waveform, and additional color schemes and UI improvements.

X0X-RMX browser emulator in Cream & Lilac, showing a 909 pattern and the Device color selector — The default Cream & Lilac exterior, shown with the WHITE LILAC LCD scheme. Play it with mouse, touch or keyboard.

X0X-RMX 1.0.0 Stable, successfully tested on a real M-VAVE FM-1. Hardware update, pattern/sample retention, startup patterns, chain playback, a twelve-minute musical run and USB audio with iPad/AudioShare were confirmed successful.
