Devon, I believe I have only gotten as far as some of the Rhythm routines. The rhythm code is based on work of Schillinger (https://en.wikipedia.org/wiki/Schillinger_System <https://en.wikipedia.org/wiki/Schillinger_System>} who developed a method back in the early 1900s. Supposedly Benny Goodman, George Gershwin, and Glen Miller were influenced by the method. Cybernetic Music seemed to incorporate the rhythm in the routines for harmonizing a melody and counter point. Those are the parts I haven’t gotten to (and the ones I was most interested in). Much of my problem is that while I know some APL, I found I had to code in APL at times to make sure I was producing equivalent output. It was a pretty tedious process for someone who hadn’t used APL in long time.
If you push further in the text and code up some the routines, I hope you will share. I would be interested in seeing how well they work.
