SHA-256 {{SHA256}}Recent releases, newest first. Removed engines listed below are historical changes, not current features.
{{CHANGELOG}}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.
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.
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.
