I haven't tried too many VST-Is, but out of the ones I've tried only one has come close to the Virus (perhaps even surpassing it) and that is Reaktor. The breadth and quality of Reaktor is superb.
I haven't tried Massive yet, though. Building my own computer (finally!), so will do soon however.
Can't wait to get everything integrated at long last. But I digress.
One VST I can't wait to check out is 'Sylenth 1' by LennarDigital. From what I've gleaned from video and audio demos it is VERY Virus-sounding, and for just 100 British smackers (139 Euros) it looks like an absolute steal!

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
