Thanks John & Bill,
My basic problem was that Data Protection was set to "on" for the foot controllers.

Bill, I am confused about how the custom panel works. I have a gig coming up this Friday and since I have only had the KN7000 a short while, I have spent most of my time transferring about one hundred of my KN2000 setups, so it's easy to forget about all the menus that were not on the KN2000.
How do I store my settings in the custom panel? I have tried setting up the "customize" section, but when I press the "Custom Panel" button, I get the default settings. I'm sure that I'm just missing something simple again. (There's an awful lot to learn -- I knew the KN2000 backwords and forwards, but the KN7000 is something else. One of the things that is really useful for a live performance is the foot pedal setting of "Increment + Decrement Panel Memory". Something that I always wished that I had.)
In the meantime, all the help that I have gotten from everyone is truly appreciated.
Regards to all,
Walt
