I have set up CS3 on my unit to vary between clean and dirty on the same amp and amp channel on my FM3, per some of the instructions on the forum. When the CS3 is assigned to one of my footswitches and I press it, the amp change is instantaneous, so it works as it should. However, if I don't have the CS3 assigned to a footswitch, and instead want it to automatically come on when I change scenes, there is a gap as if the amp is changing channels, but the amp and cab channels are the same. I have about 8 different amp parameters assigned to CS3. Is this gap normal when changing scenes and forcing the CS3 on via the CS per Scene functionality?
