AMB-1

AMB-1 turns the M-VAVE FM-1 into a generative ambient instrument built around slowly changing musical layers. Breathing voices, bell patterns on loops of unequal length, a gliding bass and quiet percussion combine through tape echo and reverb. 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.

Melodee

firmwaregithub.com

Melodee turns the M-VAVE FM-1 into a multi-engine groovebox for sound design, pattern creation and song arrangement.

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.

ChoralRoot FM-1

firmwaregithub.com

ChoralRoot FM-1 turns the M-VAVE FM-1 into a chord instrument for harmonies, strumming and accompaniment. Root notes and chord-quality controls work together to produce chords, extensions and voicings, with an independent bass part adding weight beneath them. Arpeggiation and performance modes offer different ways to animate the harmony. A looper captures chord progressions for overdubbing and live playing, while the sound engines provide editable timbres for the arrangement. The panel brings chord selection and performance gestures together in a compact layout. A browser emulator and editing tools support exploring the instrument, with a web installer for loading it onto hardware.

OberVave
