If you just want audio control and are using the installed tuner cards, I would create a basic Sysyem builder (scary I know) program and add eisc's (SB calls them RSD's) for zone and tuner card control. On the pro2 you put all your external devices and control them in simpl. You can program the AES in simpl also but I think it would take a lot longer than what system builder can make in a matter of minutes.
