I think it depends on the VSTi and how it saves/loads sounds.

Two things you could try;
Save Group .. this saves a Group of VST/VSTi, in other words the data from all four of the slots in a given track's FX area.
I've seen this save some settings when regular save didn't. You may have to Load Group after, but maybe not.

Or maybe try saving the Aria settings as a Preset in RB .. maybe this will retain the settings or at least make them easier to recall. (?)

Other than that I have seen a couple FX that simply refuse to recall settings when loaded. Never figured out why. 99% of them load just fine.
