Yeah, it's tough to see what's going on since there is no way to visualize the live pedal input at the moment.
How are you trying to look at the resulting MIDI (or, what is supposed to be the resulting MIDI)? By default the resulting MIDI from the CV input should be coming in on QuNexus Port 3 (the CV port), channel 2, either CC 112 or 113. If you're only looking at Port 1 or 2 on QuNexus you won't see anything.
Port 1 = Data to and from the keyboard itself
Port 2 = Data coming to and from the Expander
Port 3 = Data coming to a from the CV inputs/outputs
