In addition to the stock CC’s in the MIDI implementation chart, the JV/XV synths support a number of other mappable controls, all which are configurable to the point that the only possible answer is “it depends on your settings” 
Oh and FWIW, you might want to make a definition file for it. These JV-1080 and XV-3080 could be used as a starting point, the JV-2080 falls somewhere between the two feature-wise.
