Felucca Salt is a distinct Felucca firmware fork by Chance Roth, paired with a browser Studio. It retains a multi-engine FM-1 instrument while adding its own firmware refinements and an editor that can switch between a connected FM-1 and browser audio. Studio features include themed panels, an oscilloscope, configurable control layouts and a docked keyboard. The browser instrument and connected-device editor are separate modes of the companion interface. The public 0.9-salt14 beta has a downloadable firmware package and source archive. The README states that it has been tested on device, and the release records contributor testing with a physical FM-1 and an Akai MIDI source.

Sloop is free, open-source alternate firmware for the M-VAVE FM-1, based on Felucca. It turns the instrument into a four-track groovebox with three synth tracks and a 16-sound drum machine. Nine synthesis engines cover analog, four-operator FM, phase distortion, three-oscillator synthesis, tonewheel organ, formant voice, granular synthesis, lo-fi chip sounds and sampling. Designed for live performance, it combines loop recording and overdubbing with step sequencing, per-step levels and ratchets, swing, polymeters, one-key chords and 16 punch-in effects. Sections A–D can be performed live and recorded into a song. A browser-based editor provides parameter control, a drum grid, preset management and sample upload; firmware installation is also available through the browser over USB.
JIANT FM
firmwarejuanjiant-bit.github.io
JIANT FM is free, open-source alternate firmware by juanjiant-bit for the M-VAVE FM-1, based on Felucca with a song system adapted from SLOOP. It combines eight synthesis engines, including analog, six-operator FM, phase distortion, chiptune, formant voice, organ, noise and DRUM-X synthesized drums. DRUM-X morphs between two sound states, while sound randomization and macro controls encourage live experimentation. Its thermal-color interface visualizes each track as an animated organism and displays live graphs for modulation and effects. Sequencing includes parameter locks, ratchets, probability, automation and recordable punch-in effects, with eight songs organized into four sections each. Distortion, delay, chorus and five reverb models extend the sound. A browser emulator and editor are available. The project is in development and has not yet been thoroughly tested on hardware.
Skiff
firmwaregithub
Skiff turns the M-VAVE FM-1 into a six-track groovebox built on Felucca. Fourteen synth and drum engines share eight voices, with full on-device editing for six-operator FM sounds and animated envelope displays. A sequencer of up to 64 steps supports chords, ratchets, trigger conditions, microtiming, and parameter locks. A shared pattern pool, per-track song lists, and scenes support arrangement and live launches. Performance layers provide staged mutes, effect throws, and momentary effects, while recording supports overdub, step entry, and capturing the last loop played. A browser editor handles sounds, sequences, mixing, projects, and backups over USB MIDI. Skiff also provides stereo USB audio and six screen themes.
X0X
firmwaregithub
X0X is a beta groovebox firmware for the M-VAVE FM-1 and a fork of Felucca. It combines TR-909 and TR-808 drum engines, two TB-303-style parts with TB-3PO acid generators, and an eight-slice breakbeat generator. All five parts can run together, with 16 patterns, per-part step lengths and rates, song mode, and recorded knob movements. Shared reverb and digital or tape delay sends feed a master compressor with kick-keyed pumping, a resonant filter, and a limiter. A browser emulator lets you try the firmware without an FM-1.
AMB-1
firmwaregithub.com
AMB-1 turns the M-VAVE FM-1 into a generative ambient instrument inspired by Brian Eno's Music for Airports. It begins playing when switched on, combining slowly breathing voices, bell patterns on loops of unequal length, a gliding bass and quiet Euclidean percussion. Tape echo, a long tape loop and plate reverb tie the layers together. Rather than recording a conventional sequence, players choose a piece and scale, add or remove notes, freeze the arrangement and adjust the voices as it evolves. The project provides a browser emulator, illustrated manual, firmware downloads and a USB web installer. The Firmware Hub lists public version 1.3 and links the original repository and project site. Screen-reader integration reports the current page, control values and musical state over USB.
Felucca
firmwarehugelton.itch.io
Felucca is free, open-source alternate firmware by Hügelton Instruments for the M-VAVE FM-1. It turns the instrument into a four-track synthesizer with three synth parts and a GM drum track, sharing eight voices. Nine engines cover virtual analog, FM, phase distortion, chiptune, sampling, formant vocals, ring modulation, tonewheel organ and granular synthesis. Each track has a 64-step sequencer, with live loop recording and overdubbing. An arpeggiator, scale quantization, effects and a browser-based editor expand the workflow. USB handles MIDI and firmware installation without extra hardware. The developer labels Felucca as beta; the official M-VAVE updater can restore the stock firmware.
Tonitor
firmwaregithub
Tonitor is alternative firmware for the M-VAVE FM-1 by Nuno Zimas, built for electroacoustic experimentation, live ambient music and sound exploration. Six tracks combine independently chosen engines and sounds with free loop recorders, each supporting up to ten overdubs and its own loop length. Four engines cover six-operator FM, gesture-driven lo-fi synthesis, an eight-oscillator instrument inspired by the LYRA-8, and noise, logic operations and manipulated buffers. Generative paths bias new sounds toward ambient or experimental textures. Per-track envelopes, resonant filtering, granulation, bit and sample-rate reduction, and shared effects shape sustained notes and layered gestures. Sixty-four session slots store the performance state. The interface uses large text, high contrast and a distinct colour for each track to support low vision.
OberVave
firmwaregithub
OberVave turns the M-VAVE FM-1 into an eight-voice analog-style polysynth inspired by classic American polyphonic synthesizers. Each voice has two oscillators with hard sync and cross-modulation, a multimode filter with a lowpass-to-highpass morph, two envelopes, and an LFO. Poly, dual, unison, and mono modes include glide, with adjustable vintage drift and stereo spread. An arpeggiator, 32 programs, USB MIDI, chorus, tempo-synced delay, and plate reverb complete the instrument. Built on Dinghy, it is host-tested, but the developer reports that it has not yet been run on an FM-1.
ORBIT
firmwaregithub
ORBIT is a four-track groovebox firmware for the M-VAVE FM-1, based on SLOOP and Felucca. Three synth parts and a drum machine share a workflow built around sound editing, Event Tape, and a mixer. Event Tape lets you copy, lift, and rearrange sequencer events. Synth parts share an eight-voice budget across engines including analog, FM, sampling, and granular synthesis. Patterns support up to 64 steps, chords, ratchets, microtiming, and parameter locks. User macros, sample chopping, section chains, insert and performance effects, USB audio, and MIDI extend the instrument. Installation has been verified on an FM-1; hardware timing and recovery testing remain incomplete.
CoralFlower
firmwaregithub
CoralFlower turns the M-VAVE FM-1 into a chord instrument inspired by the Telepathic Instruments Orchid. Chord-type keys transform played roots into chords with an optional independent bass part, using two keyboard layouts and 27 scales. An arpeggiator offers nine patterns, including strumming, while a looper records chord progressions with overdub, undo, and timing correction. Virtual-analog and FM engines provide editable chord and bass sounds. Six reorderable effects shape the output, and USB MIDI sends chord and bass notes on separate channels. A pixel flower or coral grows from the notes you play. It is built on ChoralRoot and Felucca, with a browser version for trying it before installation.
Hortator
firmwaredeadactive.github.io
Hortator is beta drum-machine firmware by DEADACTIVE for the M-VAVE FM-1, built on Felucca. Eight tracks combine drum models and samples with a sequencer of up to 64 steps per track, independent lengths, divisions, and swing. Accents, probability, ratchets, live recording, and recorded knob movements shape patterns, while Grids generates mapped or Euclidean rhythms. A track-keyed compressor, two LFOs per track, resonators, distortion, a slicer, and delay, reverb, and chorus support sound design and performance. An ACID bass voice can run on up to two tracks. USB audio and MIDI connect it to other gear. The website lets you play the firmware in a browser. It is untested on most hardware and may be unstable.
Melodee
firmwaregithub.com
Melodee is a multi-engine FM-1 firmware derived from Felucca, with a developed pattern, song and recording workflow, sound editing, preset banks, modulation and effects. A web editor and illustrated manual accompany the device firmware. Public packages include firmware and recovery tools, and the installer distinguishes stable releases from development or release-candidate builds. Use stable version 1.4.1 for this intake recommendation. Physical FM-1 use is documented by owners, including a report naming version 1.4.1. That report also exposes a limitation with multiplexed MIDI from an OXI Split 2.
winampFM
firmwaregithub
winampFM is a Winamp-inspired alternative firmware for the M-VAVE FM-1 by Hericdk, built on SLOOP 2.6. Its interface turns the sound browser into a playlist, displays four tracks as buttons, and places effects on equalizer-style sliders. Four tracks record loops, while a tape-deck view shows takes and recording levels. Performance controls switch between solo, two-track, three-track and full arrangements, with automatic track changes and held leads. A cassette carousel previews sounds and phrases. Twenty-eight full-screen visualizers react to notes, loops, knobs and effects. The firmware also adds Brazilian instrument sounds and drum kits, and includes a browser simulator that runs the firmware through WebAssembly in a 3D FM-1 model.
ChoralRoot FM-1
firmwaregithub.com
ChoralRoot FM-1 turns the M-VAVE FM-1 into an Orchid-style chord instrument. One hand chooses roots while the other selects chord qualities, extensions and performance modes, with strumming, arpeggiation, bass and a looper available from the panel. Its sound engines and device support build on Felucca, while the chord logic comes from the ChoralRoot musical engine. The project includes a browser emulator, a firmware installer and editing tools. Public firmware packages are available, including standard and single-core variants. Community reports document playing the FM-1 version on physical hardware; testing varies by release and configuration. A shared-repository SMK-37 port also exists.
FoMni
firmwarecharlesvestal.github.io
FoMni turns the M-VAVE FM-1 into a chord harp inspired by the Suzuki Omnichord. The 16 white keys act as a strum plate, while the 11 black keys select chords. Two blendable harp voices sit alongside an organ-style chord and bass, with ten OM-84-inspired rhythms and optional synchronized bass and chord accompaniment. Controls cover sustain, levels, tempo, transposition, chord assignments, and reverb. USB MIDI lets the harp, chord, bass, and drums drive external instruments, and incoming notes can pluck the strings. A browser emulator lets you try FoMni without hardware, and a web installer loads it onto the FM-1.

Ghoulbox is free, open-source alternate firmware by Jason Persinger for the M-VAVE FM-1, based on Felucca. It focuses on dungeon synth, dark ambient and medieval fantasy sounds, adding a hurdy-gurdy engine, cathedral-style HALL reverb, cassette-style tape processing and bit/sample-rate reduction. Its curated sounds include choirs, organs, harps, flutes, dark strings, drones and crypt drums. Felucca’s sequencer, song mode, effects, browser editor and backup workflow remain available. Ghoulbox adds dungeon-themed patterns, MIDI CC control and an old-RPG interface with a skull startup screen, sword cursor and animated torches. A prepared scene starts in D minor at 72 BPM. The browser installer connects to the FM-1 over USB and saves a backup before installing.
Frodhes
firmwaregithub
Frodhes is an electric-piano firmware for the M-VAVE FM-1 that models the mechanics of a Fender Rhodes. Its voice engine simulates a hammer, tine, tonebar and magnetic pickup, with four instrument types: Stage 77, Suitcase, Early Felt and Bell Dyno. A performance page gives the four knobs assignable controls, while dedicated pages expose the voice and effects. The effects chain includes compression, drive, tremolo or wah, phaser, chorus, delay and reverb. Chord mode, scales, an arpeggiator and a pattern recorder with quantization, overdub and undo support playing and recording. It includes twelve factory and sixteen user presets, USB and TRS MIDI, MIDI clock sync and a browser emulator running the firmware as WebAssembly.
CS-1
firmwaregithub
CS-1 is a CS-80-style synthesizer firmware for the M-VAVE FM-1, designed as a MIDI sound module for a dawless setup. Eight voices each combine two channels with oscillators, PWM, resonant high-pass and low-pass filters, independent envelopes, and velocity and pressure response. Ring modulation, chorus and tremolo, portamento, glissando, and channel detuning extend the sound. Automatic aftertouch curves animate notes without a pressure-sensitive controller, while MIDI learn and clock sync support external sequencers. Stereo tape-style delay, phaser, and plate reverb with shimmer add effects. Factory sounds, user presets, and a browser emulator complete the instrument.
MYCELIUM
