Does anyone know how the switcher allocates DVE resources once you hit the limit (8)? I was recently on a show (with a Black Plus 12G, v12 software) and pushing the limits of the DVE's, but didn't have time to figure out exactly how/where it decides to steal resources from. A quick observation seamed to be that it prioritized ME's over miniME's, but I don't know if that's the default or it was purely order of operation.
As far as I can tell there isn't a way to set a priority, except (as expected) it will prioritize anything that is flagged as on-air (which helped me immeasurably). I didn't push it far enough to find out what happens when you try to use more than 8 DVE's all being tallied as on-air, however.
I know the Vision series (and I think the Acuity) will warn you if you try to recall a memory or activate a DVE resource when there isn't any left and you can choose what to do. I also know the Carbonite is not in the same family/level of switchers, but it would be nice to know at least how it's choosing to allocate. Apologies if this is buried somewhere in the manual and I missed it; I scanned through it but didn't see anything.
