Yes, I have seen the video (first one, concerning RB) as indicated in my post...
and I am familiar with the procedure of adding effects as shown in that same video.

What I do not understand is the following:
If I can add as many as 4 different effects to each track with the procedure explained in that video, what (the eck!) do I need the complete FX right side of the RB mixer??? 8 FX boxes above and 16 boxes underneath, just to do the same thing???

That was my basic question and I would love to see a nice video showing how all this FX business works...
