A question on the patches between the A90ex with the two expansion cards (JE-JV1 and VE-GS1). I just purchased this unit. I also have a Roland SC-88 Pro rack unit. Does the SC-88 just duplicate the A-90ex patches? I'm just wondering if it's redundant to keep the SC-88? I've tried pouring through the manuals to find an answer but as we all know how easy that is. Comments welcomed.
