Thanks for the tip on the export/import.

I have since located a Control:10 (late 2009), a TwinStore, and SourceOne forsignificantly less than a Control15. I know this would only give me two zones, so I'd still need to get another SourceOne or possibly could still use the Ensemble and resell the SourceOne.

Will the Ensemble work with the Control:10? Any reason not to use them together?

System #1: Control:10 and TwinStore.
System #2: Control:15 and Ensemble
