AI MIDI composition
From a short direction, create a playable MIDI draft with drums, bass, chords, and melody. Write only the melody and let AI add the accompaniment, or have it continue a song you started.
Features
OmniComposer features
OmniComposer is a DAW with powerful AI assistance for Windows and macOS. Compose, arrange, edit MIDI, configure instruments, and export in one workspace.
AI assistant
Ask for chord analysis, arrangement ideas, sound choices, and reharmonization in project context.
MIDI editing
Edit generated notes in the piano roll. Adjust pitch, length, timing, velocity, and weak phrases yourself.
Sheet music
Turn the current song into notation, or ask the AI for a score such as a string quartet. The engraved score opens in the app and exports to PDF, MusicXML and MIDI.
Sustain pedal
Write the sustain pedal under the piano roll. Ask the AI to add pedal and it pedals the part for you, changing every bar.
Jev composition model
Choose TypeSafe Jev as a composition model. It plans tempo, key, ensemble and sections before writing the song.
VST instruments and effects
Load your own VST instruments and effects and play generated MIDI with your own sound.
Export
Export finished projects as MIDI or WAV for use in other production environments.
Command line
Everything the app's AI can do also runs from the command line. Call OmniComposer from AI agents such as Claude Code and Codex, or from your own scripts, to automate everything from composing to exporting.
