Since you're looking at a VST that's about 20+ years old, yeah, it's limited. But it still works, and it's been updated to 64-bit, which is cool, as Steinberg has nothing but goodwill to gain from doing so...
But for what it does, it does simply enough, and we might not like the GUI, all the controls are there and clear.
And re: VB-1, as you've found, like another famous "bass" instrument (303), it's not the failed emulation that counts, but what it can be in-and-of-itself.
The "Classics Vol 1" package from Steinberg has the Model-1, which is a pretty decent sounding (and, because of its age, VERY modest on CPU resources) subtractive synth in the Minimoog mode. Worth checking out, too.
(I wish Steinberg would make some of their other old VST/DX effects available. They had a terrifically fake vinyl simulator.).
