From Fred:

So, I tested this with 3 machines: MacBook Pro High Sierra (10.13), MacBook Pro Catalina (10.15), and Dell laptop Windows 10 Education. 
I feel pretty good that it's good to go.

Regarding Rafael Hernandez's videos, here are my suggestions:

 - tell everyone to skip: 23-26

 - 5 & 12, and others using 'noteout':
      - macOS Catalina (10.15): use sforzando (see below)
      - SimpleSynth still works for anything below that ( notahat.com/simplesynth )
      - Windows 10, under the MIDI setup (Media --> MIDI settings...) choose 'Microsoft GS Wavetable Synth'
         This is the basic set of standard MIDI instruments using samples from ancient times
         ( soundprogramming.net/file-formats/general-midi-instrument-list )
         or people can download sforzando, some sound files, and also a virtual MIDI application ( loopMIDI from Tobias Erichsen )

 - 7, 10 need ReacTIVision and TUIO tools

 - 10 skip TUIO example - or download TUIO framework & ReacTIVision TUIO Simulator

Note: I added a library (markex) to make sure that the other random number (randomF and tripleRandtools in Tutorial 8 work.
