What began as a personal experiment grew far beyond my expectations. I’m grateful to everyone who contributed, supported the project, and made music with Felucca.
I’ve decided to step back from active development to focus on creating new instruments and music.
Felucca will remain available with occasional maintenance, but new features, issue responses, and pull request reviews are not guaranteed.
Thank you for everything. I hope you’ll look forward to my next creations.
Multi-engine synthesizer firmware for the M-VAVE FM-1, version 1.6.1. Connect the FM-1 to a computer by USB, open the web installer in Chrome or Edge and press Install; no extra hardware is needed. Installing is at your own risk: M-VAVE's updater or the installer's Return to official V15 takes you back. Try it in your browser, no FM-1 needed.
