- Add octave offset combo (-3 to +3) in title bar for MIDI input transposition - Fix waveform sidebar base note from C3 to C4 - Fix midiNoteToSliceIndex to compare pitch classes instead of raw MIDI notes - Add colored slice indicator dots on waveform sidebar keys - Embed audio data, file path, sample rate, and slices in plugin state for DAW project save/restore (falls back to file path if embedded data missing)
