They're called open strings in English (e.g. "open A"), and I'm happy to know what "leere Saite" means!
Anyway, what I mean by "even 16ths" has to do with timing, not timbral variation - hence my suggestion that you try groove quantizing it to introduce some variation.
Again, this is very subtle, but I think it's that the attacks are exactly together between instruments - it's just a hair too precise (even for Bach). If you groove quantized just the violins, for example, I suspect it would eliminate the last clue that this isn't a group of live musicians. Or perhaps you could create different grooves for the different sections.
Bottom line, though, I think I'm being very cheeky to criticize your performance. I'm not at all sure I could come close to programming your level of detail!
