Okay… I see that I’m confusing the “MIDI router” settings with the MIDI settings in the track “Event” page. Setting things up in the latter page as in the pic below has sorted things out.
The MIDI router page is pretty complex - I’ll try to wrap my head around its possible uses and how to execute those later on. Gotta take baby steps and pace myself - this thing is deep!
[BTW - thought I’d post how I figured this out here, in case it might help someone else in the future]
