This system includes some more advanced techniques using variables to simulate a 'navigate device' button.
I use three variables that stores a '3 bit' value when you select a source, and then with a press/hold on a 'system' button will send you to a different device for a quick setup, such as preamplifier sound field selections, a lighting page or whatever. Then pressing the [back] button on that page, you will be sent back to your previous device.
The concept is that you don't have to put a lighting page on all your devices, you can jump to that device page, and then go back to your previous device with one button press.
Complete CCF for the following devices. Includes all discrete power and input commands for the following devices. Nice layout and channel surfing 'popups'.
