How do I convert a MIDI file into a four-part SATB arrangement?

Direct answer

You can upload a MIDI file (.mid or .midi) to CantuStudio to generate a four-part SATB arrangement. The imported melody is preserved unchanged in the soprano line. A deterministic algorithm then scores and selects the alto, tenor, and bass placements, followed by a validator that checks for parallel fifths, parallel octaves, and voice crossings.

Recommended workflow

1. Upload your MIDI (.mid or .midi) file to CantuStudio.
2. Select a style such as classical, baroque, or jazz.
3. Review the generated draft and the voice-leading validations.
4. Export the result to PDF, MIDI, or MusicXML for further use.

Why this matters

This feature uses a deterministic beam-search algorithm for voice-leading rather than relying solely on a language model, ensuring mathematical adherence to harmony rules while preserving the original MIDI melody.

Caveat

CantuStudio produces a draft for human review and does not replace an arranger. Users must verify they hold the rights to the source melody.
