Jesse, you mentioned in the firmware forum that I might have only been monitoring port 4. Good theory 
but sadly I was connected to all four ports. And the same is true for my experience with Port 2 in the message above. I'll do a completely detailed work through over the weekend, but I only had success in my previous experiments with CC15, 4, and I only got Ableton/MIDI Monitor to "see" anything on their "Port 2", which in NDLR's terms is "Port 4" (and which MIDI Loupe also describes as NDLR Port 4).
