Description
Four tracks, 32 pattern banks and 1,024 recorded notes, plus a web editor. Its four audio outputs appear as discrete USB audio streams, which take-taker (an Android recorder) can capture as separate tracks. 1.0.0 followed 0.13.1; the 1.0.0 release is noted to have crashed on some units (fixed in later 1.x).
Install notes
Browser WebMIDI installer that saves a backup first and can return the FM-1 to V15. Releases also ship recovery archives (the 2026-10-13 correction makes them accept the unmodified V15 file).
