Tutorial 2: Transpose a MIDI clip

Goal: Move every note in the selected MIDI clip up or down by semitones.

Prerequisites: Tutorial 1 or equivalent; MIDI clip with notes.

Time: ~10 minutes

You will use: Template Transpose MIDI clip

Steps

  1. In Patchwright, open Templates → Transpose MIDI clip.
  2. Set Extension name (e.g. Transpose +7).
  3. Find the semitones setting on the transpose node (template default +12).
  4. Build & Run → confirm connected to Live.
  5. In Live, select a MIDI clip with notes, right-click → Extensions → your transpose command.
  6. Open the clip in the piano roll — notes should shift by the semitone amount.

Expected results

Where What you see
Patchwright Trigger → get notes → transpose → set notes
Live All notes moved by N semitones; clip length unchanged

If something goes wrong

Problem What to do
No notes changed Clip must be MIDI, not audio; trigger must be On MIDI Clip
Wrong interval Adjust semitones param before rebuild
Notes doubled or gone Ensure set notes replaces the full list from transpose output
