I was a bit puzzled by this but from what I can determine from using Totalmix on my UFX I can see that e.g. when I set up a fader group and assign it to fader group 1 it is only valid for the submix/Output I am currently working with. Another submix can have an entirely different setup of e.g. saved fader groups in the Groups section. Until I discovered this I was under the impression that the Groups section was common to all submixes. Am I dreaming or can anyone confirm this? It is truely an ambitious setup but what is the thought behind this? My mental image of fader groups was e.g. to group all drum faders and then use that fader collection to set levels for each submix. As it work now I need to define the fader group setting once for each submix and then use it, so I guess that there are both pros and cons with this superflexibility.
