FM1-Sampler
firmwaregithub.com
FM1-Sampler pairs the M-VAVE FM-1 with an Android phone to create an eight-track sampler and audio looper. The phone runs the sound engine, while the FM-1 provides the keys, encoders, display and USB audio output. Its sample modes cover melodic playback, one-shots, looping, sliced kits, granular textures and Paulstretch, with controls for sample boundaries, pitch, time stretching, envelopes and modulation. Record from the phone microphone, import audio files or browse the bundled sample library, then build loops and overdub individual tracks. An arpeggiator, reverb and delay sends, and tape-style speed, saturation, lo-fi and wobble controls support performance and sound design. Setup requires both the companion Android app and the matching FM-1 firmware. Loop clips are not stored as a complete project; individual loops can be saved to the library.
X0X

Pieces and scales provide starting points for music that develops without a conventional fixed arrangement. Players can add or remove notes, freeze a passage and adjust individual voices as the sound evolves. The controls encourage tending an ongoing texture, with room for both subtle changes and larger shifts in direction. A browser emulator and illustrated manual support learning the instrument, while screen-reader integration reports its controls and musical state over USB.
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.
Caravel

Weave crosses patterns by bar, step, or by combining one pattern’s rhythm with another’s notes. Scenes, song arrangements and a conductor track shape longer performances. Momentary effects, send effects, a mixer with EQ and master compression provide performance and mixing controls. The project website includes a playable browser emulator, sample tools and project backup tools.
Mutable Dreams
firmwaregithub
Mutable Dreams turns the M-VAVE FM-1 into a six-voice instrument for generative ambient music and rhythms. Assign any track to percussion, FM, virtual analog or harmonic synthesis, a modal resonator, or the custom Choir engine. Editable Biomes provide complete arrangements to explore, while sound presets change a voice without replacing its rhythm. Euclidean patterns, probability, swing, accents, repeats and shared scales shape the interplay between tracks. Per-track filters, envelopes and granular sends feed a shared cloud that can be frozen, reversed and transposed. Four live macros reshape a pattern, and contextual held-button help explains the controls. Dense combinations switch to ECO processing to keep playback within the FM-1’s limits. A browser instrument runs the same sound engine and supports keyboard play and patch-file import and export, but browser edits stay local and cannot be sent to the hardware. The FM-1 stores one personal patch; granular recordings are not saved.
Melodee
firmwaregithub.com
Melodee turns the M-VAVE FM-1 into a multi-engine groovebox for sound design, pattern creation and song arrangement.
