Thanks for this undertaking.
While I am quite familiar with MIDI and even developed a tool to generate Serial Compositions in MIDI. Having a BiaB specific tutorial for actually using MIDI is VERY welcome.
Suggestion: Where you say Click on preferences Icon wheel, add in that using Ctrl-E or in the Menu; Options->Preferences will bring up the window. In the 2017 UI that icon isn't there by default.
Cheers,
Tim
