I'm not quite following the whole "duplicate patches except for the channel" thing. Let's say that I want: A Clean patch. It switches to the Clean channel, which is on Green Mode where I left it. It has chorus and reverb in the loop. An Overdrive patch. It switches to the OD1 channel, which is on the Orange Mode where I left it. It has an overdrive in the front and a delay in the loop, via 4-cable method. Why would these patches need to be identical in any way, except for the channel assignment?
