MIDI + sheet music per instrument
Basic Pitch transcribes each stem to playable sheet music and exportable MIDI. Import directly into your DAW.

Upload a recording

Sheet music renders per instrument. Download MIDI, stems, or the full chord chart.
Research-grade models, not demos
Audio separation uses Meta's Demucs htdemucs_6s — the same model used in professional post-production. Transcription runs Spotify's Basic Pitch, trained on millions of music recordings.

Service scope, pricing and support
A score draft for practice and correction
Audio separation and transcription can contain pitch, rhythm and duration errors. Listen to the result and correct it in the editor before use. Publication-ready scores and consistent results for every instrument are not guaranteed.
Upload only files you created or have permission to process. The upload screen shows accepted formats and size and duration limits. PDF choir rehearsal is a separate feature and checks whether the score is supported.
