About this demo

This is the real firmware on an emulated FM-1 CPU, in fm1-emu by Joakim Eriksson (MIT), at commit 93cb7ee. Timing, sound and load here are the emulator's, not a device's. Saved kits and patterns stay in this browser.

The file it runs is for the emulator. It is not a release, and nothing here installs it on hardware: see installation status.
