CTL-1
Turns the FM-1 into a MIDI master controller: 4 CC banks on the knobs, program change, scale keys with chords, arpeggiator and a 4-track Euclidean drum sequencer, plus General MIDI sounds of its own.

Brick risk. Flashing this carries a known, documented risk of damaging the device.

Description
The released build is USB-only (USB MIDI plus TRS MIDI in). A Bluetooth build exists in the repository but is withheld from distribution: JieLi's Bluetooth libraries are binary-only and cannot be shipped with a GPL-3.0 firmware until a section 7 permission is granted (asked of Felucca's copyright holders). Anyone can build the Bluetooth version themselves.
Install notes
Browser WebMIDI installer, which can put M-VAVE firmware back; an FM-1 that fails to start twice comes up in a safe mode the installer can reach. Firmware file also on the releases page.
