Install and safety
Untested. No compatibility reports yet. Maru has not tested it on hardware.
Maru offers its own install only for open-source releases with a complete install record, after its installer has completed a full install and restore on a physical M-VAVE FM-1.
- Put the unit on stock V15 first, and keep your own copy of the stock file from M-VAVE’s downloads so you can go back.
- Back up your presets with the current firmware’s own export before installing.
- Rescue: none documented for this firmware.
- If something goes wrong, follow the recovery ladder.
- The author's installer can also put M-VAVE's firmware back.
