Welcome Tim B,
I´m sorry to hear that you´re not happy with the Solo Strings contained in the Special Edition, of course that´s also a matter of taste.
I couldn´t find a registration for VI PRO under your account.... do you have another account? In any case, you can check out the possibilities of VI PRO with a free demo license, available on the product page (click "try").
You will get a lot out of manipulating the samples, as shown in our video tutorials.
All instruments in the Special Editions contain samples with vibrato exclusively, there is no way to get rid of the vibrato. But it´s not a bug, just as the recorded attacks are intended to sound this way. It´s always easier to shorten an attack (with tools like VI PRO) than to add something that was never recorded.
Best,
Paul
