About
FM-1+VA keeps M-VAVE's FM engine, fixes some of its bugs and adds a virtual analogue engine, an 8-bit engine, a bitcrusher and a 64-step sequencer with ratchets and chance.
It was the first third-party FM-1 firmware. It is free and closed source; the author has said the source will be released. Tips go through Ko-fi.

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.
- 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 runs in Chrome or Edge, and in Chrome on Android.
- Keeps your presets, and can put M-VAVE's firmware back.
- A Version 98 beta adds the SMK-37 Pro, which is a separate device.
