OK, now, I think I know, what you mean. This is different way of controling.
Novation Automap works this way. It means, you can map one controller for more plug-ins. If the plug-in A is active, you control the parametr A of plug-in A. If the plug-in B is active, you control parametr A (or B, or C) of plug-in B. This is dynamic assign of HW controllers to the plug-in.
Studio One can do this too.
But Quick Controls work different way. These are not dynamicly assigned. In fact, this is the opposite. You decide, which parameters areimportant for you. You will assign this important parameter to on eof Quick Controls. The goal is, you can assign different parameters from different plug-ins. So you can control all (OK, not all, just 8) parameters from one place, one platte, from one device (CMC QC). Automap is focused on one (active) plug-in only. By Quick Controls, you can control more plug-ins simultaneously. This is the goal.
