there aren't still download for the virus... but I'd like to let you know that I published my brand new site
http://www.synthaddicted.com
I'm not sure if I'll ever create a patch for the virus (I did it indeed but I use them just to play with my band), but maybe in the future... who can tell? In the meantime I can host any patch for virus B you want to share, if you want to publish any of them for free.
Regards, Lorenzo
