Passing note for anyone remotely interested in this...
Found one minor problem with UFO depending on application.
The upgrade to AAS va-1 to va-2 allows both synths to reside happily side by side.
UFO upgrade doesn't like the freebie on my system. The same two dlls register in the vst ini file, but both don't show up as options if you wanted to chain them.
Not a big deal because the upgrade by itself has all the features and presets of the free version categorized separate from the enhanced presets. One can apply the upgrade capabilities to the freebie presets and save as needed.
This is a sleeper gone under the radar. Stereo imaging is excellent. Only negative so far (IMHO only) is that rhythmic pulsation is built into too many presets. Can however be backed off and saved for less volatile time dependent effect.
