Newbie trying to understand signal flow and block diagram XR18


Hello, new user trying to understand some basic signal flow through the XR18, I have attached a PDF with three screenshots showing faders and where I think they are on the block diagram if a more experienced user could take a look and see if I am on the right track that would be greatly appreciated. One additional question is where the green labeled FX returns tie in on the block diagram.  Thanks in advance.
