A live groovebox firmware for the M-VAVE FM-1 — for any style. Free and open source (GPL-3.0), based on Felucca by Leo Kuroshita / Hügelton Instruments. Install from the browser · Manual · Guide en français · Web editor · Releases · Report a bug SLOOP turns the FM-1 into a four-track groovebox you play live: three synths and a drum machine with 16 sounds on the white keys, nine synthesis engines, 68 sounds, 37 drum kits, your own samples, a song mode you play with your hands — and now USB audio, a MIDI keyboard on the jack, MIDI clock, lights for playing in the dark and a full backup. House, techno, hip-hop, trap, drum & bass, amapiano, synthwave, lo-fi, ambient, chiptune — it does not pick a style for you. No factory patterns, nothing to load: everything you hear, you play. The full list, and what came in…
