M-VAVE FM-1 firmware
Felucca
Multi-engine synth with four tracks and a 64-step sequencer. by Leo Kuroshita (Hügelton Instruments)

About
Felucca turns the FM-1 into a multi-engine instrument: FM, virtual analogue, phase distortion, samples, granular, drums and physical models, played across four tracks with a step sequencer, song mode and a modulation matrix.
Most other open FM-1 firmwares started as forks of it. The author publishes a web installer, a web editor and a browser emulator.

Install and safety
Beta. The author marks this release as beta.
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: none documented for this firmware.
- If something goes wrong, follow the recovery ladder.
- Returns to stock through M-VAVE's M-UPGRADE.
- The author also ships a Python install script for computers without Web MIDI.
