The sound is incredibly lifelike and certain demo patches remind me of sounds from old Vangelis and Jarre tunes... Great work!
I really, really hope that you will seriously look into creating a virtual version of the one-and-only ELKA Synthex. This very rare instrument can create some of the most fattest and beautiful analog sounds out there (Jarre 'Rendez-Vouz' for example, laser harp, etc.), and, like CS80, is pretty much unmatched by anything else.
If there is one engine that can fully emulate it, it would be your TAE engine.
