## Phase 53
Edit/MIDI tools/Note gate scales lengths from 1 to 400 percent, rounded to at least one tick. Legato ends notes at the next strictly later onset in the same clip and channel; notes in a chord end together. The final onset extends to source end. Gate expansion beyond the source rejects the whole edit. Undo restores original durations.
## Phase 54
Edit/MIDI tools/Correct to scale takes a root (0=C through 11=B) and chromatic, major or natural minor. Each pitch moves to the nearest permitted MIDI note; ties choose the lower pitch. Timing, channel and velocity remain unchanged. Corrections can produce unison notes; notes are not merged. This changes MIDI notes, not audio pitch or a live scale filter.

Snap notes to a chosen root and chromatic, major or minor scale with deterministic nearest-pitch ties.
### Tasks and acceptance criteria
- [ ] Provide the control/model behavior and accessible GUI commands.
- [ ] Validate bounds and failure rollback; preserve existing project compatibility and callback safety.
- [ ] Test the new workflow and document scope and limitations.

### Implementation status
Planned.
Implemented: root-aware nearest-pitch correction to chromatic, major or natural minor scales, with lower-pitch ties and MIDI endpoint bounds. Core root/tie/endpoint/invalid-input and GUI pitch-refresh tests pass; note IDs and timing persist.
