Felt Orbit ORHACK demo v6
- Based on v3: NO C3/C4/root-note pitch changes.
- Octave 0 pitch behavior is exactly the pre-root-experiment behavior.
- Fix targets latch only: while AUX latch is ON, note-offs are not flushed by a later note-on.
- Stored note-offs are released when latch is switched OFF.
- Latch-off release remains the longer v3 decay.
