Score and piano roll

User scores are a phase 2 capability already available in the app. Find them in the Score (Partition) section on the project screen — expand the panel if it is collapsed.

Capabilities

• Open the Score section.
• Import MIDI or create a blank score.
• Edit notes in the piano roll (voice, velocity, confirmed quantize, transpose, key / meter, chords).
• Export MIDI or preview YuE2 ABC, then start a generation.

Prepare a generation

1. Open Score.
2. Import a MIDI file or create a blank score.
3. Edit in the piano roll and validate the score.
4. Preview ABC (cot ≠ off), then start audio generation.

Without a user score, phase 1 generation (style + lyrics) remains available. A generation’s captured ABC (Partition ABC (prise)) is separate from the editor.
