Song to MIDI Converter
Turning a whole song into MIDI is the dream — and also the hard case, because a full mix layers vocals, drums, bass and instruments on top of each other. AI transcription pulls out the most prominent pitches, which is perfect for grabbing a lead melody, a hook, or a recognizable line to build on.

Free and processed on-device · powered by Spotify's open-source Basic Pitch model.
Drop a song into the song to MIDI converter and it transcribes the audio on your device. For the cleanest result, an isolated stem (just the vocal or just the piano) will always beat a dense full mix — but a clear single-instrument song works well as-is.
Grab the melody fast
Get the main line of a song into MIDI so you can study it, transpose it, or re-harmonize it in your DAW.
Stem tip for accuracy
If a full mix is muddy, separate a stem first (e.g. an a-cappella or instrumental) and convert that — far cleaner notes.
Unlimited and free
No paywall, no daily cap — convert as many songs as you want, with nothing uploaded.

Song to MIDI — FAQ
Can a song to MIDI converter handle vocals and drums?
You can try it, and the tool will transcribe the most prominent pitches, but dense mixes are inherently hard. For a clean part, convert an isolated stem instead of the full mix.
Is converting a copyrighted song to MIDI allowed?
Transcribing for personal practice or study is common, but distributing MIDI of copyrighted music may not be. Because everything stays in your browser, your conversion is private to you.
How do I get a better melody line?
Use a cleaner or more isolated recording, and raise the note-confidence threshold in Advanced settings so only the strongest pitches become notes.
