I'd identified the FastLane as the culprit but I wasn't nuts about spending $140 on a new box just yet. So I got a USB B to A cable and directly wired the Axiom into the computer, running the Roland (where I had no choice) through MIDI. I figured that if both keyboards weren't going into the FastLane they couldn't get mixed up in the FastLane. And so it was, per MIDI Monitor. I had to reboot HW for it to see the USB input, but it's working fine now.
Thanks to all of you who offered helpful breadcrumbs toward a solution.
Thanks, Jeffrey. Excellent.
