Tutorial 4: Scale-aware chord / arp

Goal: Generate MIDI notes in your Set’s scale — as a chord block or arpeggio — into the clip you right-click.

Prerequisites: Getting Started; Live Set with scale enabled (Live 12 scale tools).

Time: ~20 minutes

You will use: Template Scale-aware chord/arp generator (featured)

Steps

  1. In Live, set your desired scale for the Set (root note + scale type).
  2. In Patchwright, load Scale-Aware Chord/Arp from Templates or onboarding.
  3. Set Extension name (e.g. Scale Chord Arp).
  4. Review highlighted editable params on the canvas (if shown after template load):
    • Mode — chord vs arp behavior
    • Start beat, arp step, note length, velocity
  5. Build & Run → connect to Live.
  6. Create or select an empty MIDI clip, right-click → Extensions → your command.
  7. Open the piano roll — new notes should match the Set scale.

Expected results

Where What you see
Patchwright Graph reads Song scale (root + intervals), builds notes, writes to clip
Live MIDI notes appear in the clip; pitches follow the Set scale
Changing scale in Live Re-run the command after changing scale to regenerate

If something goes wrong

Problem What to do
Wrong pitches Confirm scale is set in Live; graph reads Song root and intervals
Empty clip Use MIDI clip trigger; clip can be empty before run
No command Rebuild; check Developer Mode and Extensions enabled
Notes out of range Adjust template params or start beat
