Click for details

The Chord Mapping script in this repository is a working example demonstrating:

  • Chord event scraping from the Chord Track
  • JSON file output using Host.IO.createTextFile() and JSON.stringify()
  • Data extraction from chord events (name, type, root/bass pitches, timing)
  • File I/O operations with Host.Url() path construction

Source Code Files:

Key features:

  • Processes selected chord events in EventEdit context
  • Saves chord data to Chord_Mapping.json in local://$USERCONTENT/
  • Creates both JSON and text output files
  • Demonstrates proper error handling for file operations

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.
