Lock & Reroll — User Manual

Lock & Reroll lets you protect specific notes in a pattern and regenerate the rest. It works in the piano roll and all melodic editors (wind, strings, bass).

Locking Notes

Alt+Click a note to toggle its lock. Locked notes show a blue tint and a padlock icon.

Locks are stored as per-note metadata. They survive undo/redo and are preserved when you save the project.

Rerolling

Press Ctrl+R to regenerate all unlocked notes. The locked notes stay exactly where they are; everything else is replaced with new material.

The generator uses:

• Your current key and scale
• The section's chord progression (if any)
• The active genre profile for rule weights and style

The result is undoable — press Ctrl+Z to get your previous notes back.

Typical Workflow

1. Generate a melody (AI prompt, rule-based, or Phrase Contour).
2. Play it back. Identify the phrases or moments you like.
3. Alt+Click those notes to lock them.
4. Press Ctrl+R to regenerate the rest.
5. Listen again. Lock any new notes you like.
6. Repeat until you're happy with the whole pattern.

Tips

• Start broad, narrow down — generate a full pattern first, then lock the highlights and refine the transitions.
• Use with Phrase Contour — draw a shape, generate, lock the peaks and valleys, then reroll to tighten the connections.
• Switch genres mid-reroll — lock a verse melody, change genre profile, and reroll to hear the unlocked parts in a different style.
• Lock all before editing — if you've manually composed notes and want to add generated material around them, Ctrl+Shift+L protects your work before you generate.
