About PureMIDI

PureMIDI is an online AI audio-to-MIDI converter. Musicians and producers upload a recording and get MIDI plus sheet output, then refine the notes in a browser MIDI editor. It is built for people who want editable music, not just a waveform.

The story behind PureMIDI

Why did you build it?

Turning audio into editable notes usually meant slow manual transcription. PureMIDI uses AI so a recording becomes MIDI and sheet music you can fix in the browser.

Who is it for?

Musicians, producers, teachers, and hobbyists who want MIDI and sheet music from audio without a desktop DAW.

What's next?

Clearer transcription on dense mixes and easier export from the browser editor.
