Overview​

Scrapes selected chord events from the Chord Track, extracts data (name, type, root/bass pitches, timing), saves Chord_Mapping.json & Chord_Mapping_Results.txt to local://$USERCONTENT/.

Usage​

  1. Open Chord Track in Arrangement View, select desired chords (or Edit > Select All).
  2. Run "Chord Mapping" from Action menu (API Tests > EventEdit).
  3. Check local://$USERCONTENT/Chord_Mapping.json & Chord_Mapping_Results.txt (e.g., ~/Library/Application Support/Studio Pro/ on macOS).

Tips​

  • Processes only selected chords (no auto-select).
  • Use in EventEdit context on Chord Track.
  • JSON includes: name, type, root/bass, pitches, start/end times, isLydian.
