Piano to MIDI Converter

Piano is the ideal instrument for audio-to-MIDI: clear note onsets, a wide range, and a sound the model knows well. Because Basic Pitch is polyphonic, it transcribes chords and two-handed playing — not just a single melody line — which makes piano to MIDI genuinely useful for arranging.

Piano to MIDI — FAQ

Can it transcribe piano chords, not just single notes?

Yes. Basic Pitch is polyphonic, so it detects multiple simultaneous notes — chords and two-handed playing transcribe well from a clean piano recording.

Does it work for both acoustic and digital piano?

Yes. Any clear piano audio works. A direct recording from a digital piano or a well-recorded acoustic both transcribe nicely.

How do I capture timing and dynamics?

Note timing is preserved from your performance, and the model estimates velocity from loudness. Set the tempo in Advanced settings to match your piece for a tidy grid.
