A full pipeline, from idea to score

Every module is built for musicians: generate, arrange, edit and export without leaving the app.

AI composition

Describe a style and a length: the AI generates chords, sections, articulations, melodic lines and drums right on the timeline. Add an instrument to an existing piece in one click.

Multi-provider AI

Built-in clients for Mistral, Gemini, Groq, DeepSeek, Claude, Grok and Qwen. Store multiple named keys, or work key-free through the clipboard.

Timeline editor

A sequencer of horizontal tracks: riff modules, repeats, a chord lane, tempo and dynamics lanes, a measure ruler. Copy, paste and rearrange on the fly.

Harmony in scale degrees

You compose by thinking in scale degrees (I, IV, V…) rather than fixed chords: the progression stays correct in any key and transposes in one click. Dedicated chord track, functional cadence generator, progression suggestions and automatic voice-leading.

Engraved score

View each track in professional notation (Bravura font), with zoom and a playback cursor. Export to PDF (A4) and native MuseScore (.mscx).

Drum editor

A pattern catalog (standard, Africa, Australia), draw your own grooves, AI generation and one-click conversion of riffs into drum kits.

Melodic lines

From rhythm-only lines where the engine picks pitches from the chords, to fully written melodies and counter-melodies.

Procedural composition

100 % algorithmic engines (serial, cellular automaton, L-system, genetic, 1/f fractal) and Bach, Vivaldi, Ghibli / Hisaishi style engines.

Import & audio

Import MIDI and MuseScore (.mscz/.mscx) onto the timeline. SoundFont audio engine (MeltySynth), MIDI input and microphone note detection.

Multilingual & up to date

8-language interface, automatic updates at startup and built-in bug reporting. Add a language without recompiling.
