I have a Helix and 2 PowerCab-112 Plus, connected via the L6 Link Cable (works great). The question I have is around the PowerCab Software, can I connect separate USBs cables to both Cabs and bring up two PowerCab Edit Sessions? or can I modify both with a single USB cable? Right now I load IRs in to one, disconnect the USB cable and plug into the other to load IRs. Be nice if the Helix App (just on a PC or Mac) had the ability to manage the PowerCabs. So far, they sound great.
