What’s in the remix
Build and reshape chords
A paged step sequencer, auditionable progression generation, preset randomization and MORPH crossfading between two presets.
Play with your setup
Velocity-sensitive keys, external MIDI chord controls, synced loops, tempo nudge and USB audio recording.
Two sources. A new way to play.
- GRAIN follows Prophet in the engine list, with real A/B waveforms and source preset names.
- Capture factory sounds from nine engines and reshape them with Position, Size, Density and A/B blend.
- SOURCE A/B preset selection moves one entry per detent, without needing FINE.
- 64 USER presets and 30 loop slots retained; Init preset is in SAVE.

{{CHANGELOG}}Install from your browser
- Fully charge the FM1, connect it directly by USB and keep the computer awake.
- Open the installer in a desktop browser with Web MIDI SysEx support. Close your DAW or other apps using the FM1.
- The page checks the published firmware file. Press Connect & install and allow MIDI SysEx access.
- Keep the downloaded backup. Leave the page open and the FM1 connected until the update completes.
The firmware package matches the {{VERSION}} file checked with the command-line installer. Browser update tests use simulated devices; a physical FM1 browser update remains to be verified.
Backup, restore and sound files
The installer includes backup/restore and a 64-slot USER sound librarian. Export, import, rename or delete supported sounds; FM6 also supports compatible SysEx files. These are separate from the device’s on-board factory-preset selection. The browser does not upload your backup or SysEx files to a server.
Returning to the original firmware
The installer includes a return-to-stock section. Supply your own unmodified official M-VAVE V15 file; its known SHA-256 is checked locally. Official firmware is not bundled. Some firmware families are refused by the upstream compatibility check; read the installer’s explanation before proceeding.
