I owned a virus a back in the day. But now i have this virus c, has killer reverb, and the internal banks finally have great presets that are very varied. this thing does pads and string much better than the virus A ever did. more filter saturation settings, and with the new os i get moog filters that add an entirely different sound to this beast that even further sets it apart from the b and the a and the other virtual analogs. Vas are only as good as their built in fx, and the phasers and the verbs and delays prove this thing is the king of the hill. The osc is kind of weak, but the filters rule, simple great digital filters. I no longer have a need for a jupiter 6 because of this synth… i love the high pass and bands pass leads i can make with this thing, it does everything, great bass, agressive sounds, fx, pads, ambience, in your face, soft, mean, mellow, trippy weird. you name it. It is now my favorite digital synth ever made. I compared this to all the soft synths including the korg legacy, and this thing destroys all computer based VAs, it smashes them to little pieces. But still, it pales next to my Real Analogs for in your face sounds. The virus still aliases a bit, sounds great in the middle a tad iffy up high and down low. This thing is designated to filling in the cracks after my real analogs are in the mix. A jupiter 8, sh2, and moog through my ksp8 will eat this thing for lunch.. Virus C kicks the andromeda A6 in the ass hands down!
