Thanks SonnieThe Pro kit does allow some flexibility, but IMO it is not worth the extra cost, which is over $500 with the license, even if you can get the kit at cost or close to it. In likelihood it will cost you over $600. For me, XT32 does well enough in the mid to high end... and I use my Behringer 1124p for my low end prior to running Audyssey, so that I can get any large peaks out of the way. Audyssey just can't deal with those very well.
I control everything with a home automation system. AFAIK, quick select can't do just ch levels, etc. it stores everything (including source). I have extensive macros that switch devices on an off and change lighting scenes, when changing sources turning TV on/off, etc.. I know I can do it via IP and RS232, so I'll program those into my macros and do ti that way when I get a chanceWhy don't you just use the "Quick select" buttons? All then current settings (source, main level, channel level, Audyssey mode etc.) will be saved and remembered. True, you sacrifice another quick select setting. But from your primary question, I gather that it is much easier to change the source or main level after having selected the currently preferred channel level set. Plus, you need no additional remote or circuitry.
If you happen to own a smartphone, there are apps out there that offer a much quicker access to channel level setting on the fly.
Will double check when I get homeI bet that DeRemote has the function, it is even shown in the iTunes-screenshots. Since I'm using DeRemote on my iPad rather than the iPhone, I cannot immediately tell you how to get there. I'll try it tomorrow and tell you about it.
