Create or duplicate tracks

Goal: Add a new MIDI or audio track, or duplicate an existing track, from Live’s right-click menu.

Time: ~15 minutes

Steps

  1. Open Create MIDI Track from Templates (or a duplicate-track template if available).
  2. Set trigger scope to On MIDI Track or On Audio Track — match where you will right-click in Live.
  3. Add Song context; wire Song into createMidiTrack (or the create/duplicate action your graph uses).
  4. Wire trigger Run → create action Run; chain set track name inside a Transaction if you rename in the same step.
  5. To duplicate instead of create empty, use the duplicate action from the palette and wire target track into it (template or PatchAI can suggest the layout).
  6. Set Extension name and Build & Run.
  7. In Live, right-click a track (or empty track area per your trigger) → Extensions → your command.
  8. Confirm the new or duplicated track appears with the expected name.

Expected result

Live shows a new track at the end of the list (or a duplicate next to your workflow’s SDK behavior). One undo removes the track if you wrapped creation in Transaction.

If something goes wrong

Problem What to do
Nothing added Song must be wired; Run must reach the create/duplicate node
Wrong track type Use createMidiTrack for MIDI; pick audio create nodes for audio tracks
Command on clip menu Track creation needs a track trigger, not On MIDI Clip
Duplicate wrong track Wire target from trigger into duplicate input
Async delay Some create actions finish after a short wait — Patchwright handles this; rebuild if build warns about async
