S2400 doesn't see incoming midi over USB B in MIDI monitor

Health issues have prevented me from digging into the 2400 until this weekend and I’m not having much luck using it as a tone generator with Logic Pro. The DAW and the Audio MIDI Setup both recognize the unit on the USB bus, but I can’t get the samples to play back or any recognition that there are incoming notes on the monitor. I’ve watched Alex Ball’s Video Manual pt. 7 about a dozen times and gone over the pdf but I’m not having any luck.

I have samples loaded to A1 and A2 and I’m sending a repeated C1 (36) midi note over all channels to the Isla Midi Out port in Logic.

From the Pattern 1 bank A screen with the A button on A1 on, I open sync to see these settings:
Clock Src-USB B
