You may have run across something interesting, here.
I assume you already have the ProBox configured to act like a Mackie Control Universal (ProBox MIDI Port 4), and two Extenders (ProBox MIDI ports 3 and 2... going from right to left)?
I haven't started Logic in months - using Studio One exclusively, lately. However, when I just did to confirm which button was to push to activate V-Pots for Pan (I think it's the Compressor button), the V-Pots did nothing in Logic.
I also have an actual MCU unit connected simultaneously, where the V-Pots also no longer worked to control pan.
I also have a PreSonus Faderport (2018/single fader), and Pan would not control Logic here as well, even when re-starting the unit in Logic mode.
When I started Studio One instead, Pan worked right out of the box via the V-Pots on the D8B and on the "real" MCU (...and on the Faderport, once I restarted it in Logic mode).
The D8B's ProBox operation can also be switched between HUI, Mackie and Logic modes, but as long as it is in Mackie or Logic mode, it should work. As mentioned, it DID NOT, when I just tried.
I'll have to troubleshoot a bit at a later point. Maybe a Logic update (I still installed them, even though I didn't use Logic) broke something... or maybe I just have to clear my control surface setup and start over, in case any sort of preference file got corrupted with an update, or something... but I think if you have the ProBox correctly configured, you might be impacted by the same problem.
I'm just starting my workday here, so I can't look into this right now. I'll try to troubleshoot in the coming evening(s), but if anybody else on this forum can check ProBox operation with a current/recent version of Logic, it would be interesting if you're experiencing the same issue.
It used to work just fine, when I tried last - but again, this was quite some time ago.
