Install from your browser

  1. Fully charge the FM1, connect it directly by USB and keep the computer awake.
  2. Open the installer in a desktop browser with Web MIDI SysEx support. Close your DAW or other apps using the FM1.
  3. The page checks the published firmware file. Press Connect & install and allow MIDI SysEx access.
  4. 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.
