Just wanted to also echo one of nicoroy123's points.
Since removing the Virus TI from my setup earlier this month (disconnected, uninstalled drivers and Virus Control), I have had absolutely zero problems with my setup. I actually just completed a track which has been signed and I had zero (that's right ZERO) issues with Cubase 6.5.5 x64 and my other plugins. Not one crash, not one hang on exit, not one hiccup.
It's amazing how much you actually get done when you don't have to worry about this sort of stuff and most importantly, I'm absolutely stoked with how the tune turned out and so is the label.
Synths I used were Massive, Spire, Sylenth1 and Razor all of which give the Virus TI a good run for its money soundwise. Razor is particularly interesting, highly recommend checking it out
As I mentioned in my post above, I totally understand why people would love the Virus TI as a hardware synth, but for many people like me who have been spoiled with VST technology, we just bought the Virus TI to use as yet another VST instrument in our DAW since there's no fully soft version of the Virus synth. Unfortunately, the synth fails on this front.
Needless to say, my Virus TI will be going on sale very soon, it's in absolutely great condition, hardly used (literally)
P.S.: To Marc, I did report all my BSOD and crashing issues and provided logs and minidumps to Access Music support (Ticket ##SI00077645). I hope it will at least help make the synth more stable for other users.
