FM-1 EMULATOR

The LUXR firmware running in your browser: the same C code as on the M-VAVE FM-1 (sound engine, sequencer, screens, patch store), compiled to WebAssembly. Play it with the mouse, touch, your computer keyboard or a MIDI keyboard.

For the mouse: SHIFT lock keeps GLO held, so you can click a key or turn a knob with SHIFT (SHIFT + F#3 keeps snapshot 1). Click again to let go. Right-clicking GLO does the same; on a touch screen hold GLO with one finger.

Patches

The emulator starts with 13 preset patches. Import the .luxr file the LUXR update page saves with “Download backup”. Each patch goes to its own slot and is converted like a restore on the device. Click a blue slot to load it. Patches stay in this browser; “Export backup” writes a file the update page can restore to a real FM-1.

MIDI in MIDI out

MIDI works in Chrome and Edge once the emulator is on. Notes on a sound's MIDI channel play it, alone on its channel it plays tonally (C3 = original pitch).
