Free Studio One MIDI generator — build complete MIDI arrangements (melody, chords, bass, drums) in your browser and import them into Studio One. No sign-up.

The generator lives in the studio — roll full arrangements, edit every note, export MIDI, WAV or MP3.
MIDI Maker is a free online MIDI generator that rolls full arrangements — melody, chords, bassline and drums — as standard MIDI that imports cleanly into Studio One. Generate in the browser, then swap the parts onto your own instruments and edit everything in the Music Editor.
You can also skip the file: Live MIDI Out (Chrome/Edge) streams the generator’s notes and clock to a virtual port that Studio One reads as an external keyboard, so a record-armed instrument track captures the performance as it generates. The full setup is in the MIDI Out docs and the live MIDI sequencer guide. See the Live MIDI Out docs and the guide to using MIDI Maker as a live MIDI sequencer for the full walkthrough.
Yes — Studio One imports the .mid as instrument tracks, so the pitched parts play through Mai Tai, Presence XT or any VSTi, and the drum part’s General MIDI mapping matches Impact XT’s GM kits.
Yes — enable Live MIDI Out in the studio (Chrome or Edge) and point it at a virtual MIDI port (the IAC Driver on macOS, loopMIDI on Windows). Add it under Studio One → Options → External Devices as a New Keyboard, then record-arm an instrument track to capture the generator as it plays.
Yes — everything the generator writes is royalty-free with no attribution required. Free and Pro output is licensed for personal projects, and the Studio plan adds a commercial-use licence for releases, games, videos and client work.
The MIDI Maker studio rolls complete, editable arrangements — melody, chords, bass and drums — you can export to any DAW. Free, in your browser.
