## 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.
## Phase 55
Edit/MIDI tools/Shape velocities scales from 0 to 400 percent, rounds, then applies an offset from -127 to 127. Results clamp to 1..127, keeping every note audible rather than introducing velocity-zero note-offs. Use 0 percent with a positive offset for a fixed velocity. No randomization is applied.

Apply bounded velocity scaling and offsets to selected MIDI clips, with explicit clipping to valid MIDI velocities.
### 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: rounded velocity percentage and offset transforms with explicit 1..127 saturation. Core scale/offset/extreme/invalid-input and GUI velocity-refresh tests pass; timing, IDs, pitch and channel remain unchanged.
