OK I just had a better look. I guess the only outputs available for programming are on the zone extender. I've been programming System Builder for a year now and things are just starting to make a lot of sense. Still have to figure out how to get text from feedback (such as song info from iPod) or how to get a volume bar going from volume feedback.
You could also take your 12V trigger out from your AVR and run into an IO port and program it as a digital input and add it to your global expression.
The ports are rated up to 30V.
