Frasil turns the M-VAVE FM-1 into an instrument for ambient drones and evolving textures. Tap notes or chords to latch layered choir, harmonic partials and breath-like noise, then use pressure to swell them. Shimmer, freeze and a spacious reverb extend the sound, while GLINT adds playable FM bells with an arpeggiator and step sequencer. A separate bass voice can hold a note or follow its own sequence. Route slow or tempo-synced LFOs to the sound, shape the layers from dedicated pages, and save complete scenes with notes, sequences and tempo. Scene morphing glides between saved sounds, and USB or TRS MIDI brings external notes, pressure and clock into the instrument. The website includes a playable browser version and a detailed guide; the River scene library and backup tools transfer scenes between the FM-1 and your computer.

firmwaregithub
Vector37 is experimental synthesizer firmware for the M-VAVE SMK-37 Pro, inspired by the Beetlecrab Vector. Four corner sounds each combine two overtone generators, a blend control, and a filter. A sun follows a path while a moon orbits it; the moon’s position determines the mix of the four sounds. Pads select and control the planets, eight knobs shape the selected sound, and four faders adjust the path’s family, size, speed, and morph. Eight stored sounds provide starting points, and TRS MIDI output sends the keys and wheels. A browser simulator lets you explore the engine and screen before installing.
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.
winampFM
firmwaregithub
winampFM is a Winamp-inspired alternative firmware for the M-VAVE FM-1 by Hericdk, built on SLOOP 2.6.
