What it's good at

Audio to MIDI works best on one instrument at a time: a sampled melody, a bass loop, a guitar riff, a vocal line, a synth lead. AnyToMIDI uses Spotify's open-source Basic Pitch model, with presets that keep each instrument's notes in its real range so harmonics don't turn into extra notes.

For a full song with several instruments, switch to Whole song: it separates the parts before converting.

MIDI that sits on the grid

Most converters export at a default 120 BPM, so the notes drift across your bar lines. AnyToMIDI detects the recording's tempo and first beat and writes them into the file. Drop it into a project at that tempo and the notes line up.

Your audio stays on your device

In One instrument mode the model downloads once (under 1 MB) and runs in your browser. Your recording is never uploaded.

Questions

Is it free?

Converting one instrument is free and unlimited, and runs in your browser. Downloads are free too: 3 a month with a free account. Piano and whole-song mode give you a free 30-second preview; Pro converts whole files up to 15 minutes.

Will the MIDI line up with my DAW's grid?

Yes, for music with a steady beat. AnyToMIDI detects the tempo, writes it into the file and moves the first beat onto a bar line, so the notes land on your DAW's grid at the project tempo. If it reads a slow song at double speed, use the ½× button before downloading.

Why isn't every note perfect?

No converter gets dense, many-instrument audio exactly right: chords and full mixes are genuinely hard. A clean single line converts very well. For a whole song, AnyToMIDI separates the instruments first so each one is transcribed on its own, which gives a much better starting point than converting the mix in one go.

Which DAWs does the MIDI work in?

Any of them: it's a standard MIDI file. FL Studio, Ableton Live, Logic Pro, GarageBand, Cubase, Studio One, Reaper and BandLab all import .mid files.
