Saving

SAVE keeps your chords and sound in this browser, as the FM-1 keeps them in its memory. Factory reset forgets them. It is the firmware, not a recording: what you hear is FoMni-1 running, at the FM-1's 44.1 kHz. The idea of running FM-1 firmware in the browser comes from Groove OS's emulator.
