Positioning

Clean sound without the noise typical of AI-generated audio.

Unlike conventional AI music services that render finished audio, OmniComposer uses an LLM to compose as MIDI data. Because it does not generate audio directly, you avoid the noise and quality degradation common in AI-rendered tracks. Sound comes from the instruments you choose, and every note remains editable.

Production Loop

Compose by prompt. Fix notes in the piano roll. Add tracks or export by prompt. Play through your instruments and export to MIDI/WAV.

Who It Is For

For anyone who needs game BGM, video BGM, practice material, or rough sketches fast.

You can start without composition knowledge or instrument experience. Describe your idea in words to get a draft; if you have experience, refine it further in the MIDI editor. Write only the melody yourself and let AI handle the accompaniment, or have AI continue a song you started halfway.

01

Composition

Build the song skeleton with melody, chords, bass, and drums.

02

Arrangement

Compare different structures, densities, and verse/chorus variations.

03

Finishing

Connect MIDI editing, instrument choice, effects, and export.

Getting Started

You do not need to play piano to compose.

OmniComposer is not software only for skilled instrumentalists. Even if you want to write music but cannot play an instrument, describing mood and purpose in words gives you a draft with melody, chords, bass, and drums.

You do not have to perform every note yourself from the start. AI creates the MIDI draft, and you refine it in the piano roll until it becomes your song.

Good fit if you

No instrument experience but want to try composing. Starting DTM but unsure where to begin. Need BGM for games or video projects. OmniComposer is a production environment for people like you.
