Transpose and quantize notes

Goal: Shift every note in a clip by semitones and snap starts to the grid.

Time: ~10 minutes

Steps

1. Load the Transpose MIDI clip template or build: On MIDI Clip trigger → MidiClip: notes → process → MidiClip: set notes.
2. Wire target into get notes and into set notes.
3. Add a transpose node after get notes; set semitones in the node (+7 up, −12 down, etc.) or wire from a dialog.
4. Optional: add quantize after transpose — set grid size (for example 1/16 note) in the node settings.
5. Wire the final note list into set notes.
6. For user-chosen semitones, add Show Dialog before any Transaction, wire dialog outputs into transpose, then Build & Run.
7. In Live, right-click a MIDI clip with notes → Extensions → your command and check the piano roll.

Expected result

Every note moves by the semitone amount you set. If quantize is enabled, note starts align to the chosen grid; velocities and lengths follow your node settings.
