I hate to disagree with the other posters, but there are 3rd party VST interfaces for the Access Virus a,b, and C.
It sounds like you are new so people probably didn't want to confuse you. The VST isn't necessary for operation, but rather provides a slick interface in your host so you can control it from your Software instead of diving into menus on your hardware. Once you start making your own patches you will see how useful visual feedback is as well as the ability to control directly from your DAW of choice IMO
None are perfect solutions or as slick as the new TI option.
