Install and safety
Untested. No compatibility reports yet. Maru has not tested it on hardware.
Coming after hardware verification. Maru will offer installs only after its own installer has completed a full install and restore on a physical M-VAVE FM-1, and only for open-source releases whose authors have been told.
- Put the unit on stock V15 first, and keep your own copy of the stock file from M-VAVE’s downloads (opens in a new tab) so you can go back.
- Back up your presets with the current firmware’s own export before installing.
- Rescue: Hold OCT− and OCT+ while switching on to boot stock firmware until the next power-on. (The author's documentation).
- If something goes wrong, follow the recovery ladder.
- US$29 one-time on the author's site, including 1.x updates (checked 2026-10-12).
- Built on top of stock V15; its install page can also put V15 back.
