Here is an
interesting post I saw on KVR....
The guy who says "I have the Virus TI2 Polar and x2 Ultra Novas.. i bought another Ultra Nova just for more parts as i love the sound. I wish Novation had made the Ultra Nova 4 part or more cause the sound appeals more to me than my Virus. The Virus is a great sound but the Ultra Nova's get more use. I hope Novation considers producing a new Synth with more parts/polyphonic in future." is none other than Rob Lee, who I would say is one of the better sound designers for EDM type sounds out there at the moment (or at least the type of sounds I aim for).
If you're not familiar with his sound sets, you can hear them at this link. I guess if you don't like his sounds, you may not agree with him about the Ultranova sound

Maybe I'll contact him to see why he doesn't make a sound pack for the UN. I read somewhere something about editing large numbers of sounds on it is a bit of a hassle even with the librarian, so maybe that's it. Also I know he was trying to contact Novation about doing one and was having trouble getting in touch with them, so maybe he's built up enough of a reputation that he can hold out for the big bucks
... Given his talent and the lack of sound packs available for this synth, I'd think that would be a killer opportunity for him.
I also found it weird that Adam Van Baker owns a Virus but claims it doesn't get as much actual use in his music as Zebra and Massive. He even wrote a Jupiter 8000 inspired plugin but has never down a soundset for the Virus to my knowledge? Weird.
