Python, Inside JavaScript, Inside a DAW

This article describes the development of PyTheory, a Python-based music theory library, and its integration into Ableton Live as a DAW extension. The author explains the problem of losing creative flow when having to alt-tab to external tools for music theory questions. The extension allows users to right-click MIDI clips to identify keys, chords, and progressions, and perform actions like harmonization, reharmonization, scale conforming, and generating full song sketches. The article focuses on the technical implementation of embedding Python inside a DAW environment, making it highly relevant to IT/technology topics such as software development, API integration, and creative coding.
