That's correct. You need the pan mod to get VCO panning (available as a kit online or as a DIY from the parts list and instructions). With the kit, the panning is set via pots. You can change the pan of the pots at anytime but they're global to all patches. I have Gligli and the pan mod on my Prophet 600 and IMO it's well worth the investment. (I also have the techsmechs Fatar keyboard and Prophet 5 knob caps, both of which I also recommend as the stock keyboard, even when well cared for, is not a great experience.)
