Extend the fixed Soft Keys/Sub Bass presets into editable instruments.
### Tasks and acceptance criteria
- [ ] Define bounded oscillator, envelope and filter controls with metadata and defaults that preserve existing preset sounds.
- [ ] Provide instrument parameter editing, automation and reusable preset save/load through public C APIs.
- [ ] Support channel pitch bend with a documented range and sustain/note lifecycle behavior.
- [ ] Persist parameters and presets with explicit version migration, undo and failed-preparation rollback.
- [ ] Verify sample timing, block partition consistency, bounds, aliasing behavior and callback safety.

### Implementation status
Planned. The current instruments expose no editable parameters or pitch bend.
Implemented: five bounded oscillator/envelope/filter/bend controls, absolute-time
automation, instrument editor and reusable preset C APIs/GUI commands. Format 14
persists bindings and reads v1–v13, preserving legacy default sounds. Core,
reliability and GUI tests pass, including preset/migration, exact partition and
pitch-bend offset regressions. See BUILTIN_DEVICES.md and PROJECT_FORMAT.md.
