think you may be confusing voices with multi-timbral parts(??)!
you can change the pitch on a polyphonic patch, no problem. but that patch can be a single, meaning just one part is enough to give you that. if you play a patch in "poly" mode (means polyphonic), it's got one voice in there for each key pressed to a limit of 32 available on the Virus C.
so with such a patch of up to 32 voices you could adjust the pitch with pitch wheel easily, you can decide the range of the pitch shift.
for multiple patches playing at once, then the answer is no. but you could get near that with a pitch shift plug-in and assigning pitch parameter to the pitch wheel on your keyboard, which is what you'd have to do if you had a recording of a group of sounds (maximum of 16 on Virus btw) and you wanted to pitch shift them all (unless you're making some huge build up on some crazy EDM track can't see why you'd want to do that anyway...), so...
The Virus seems to be able to cope with what you want with just one part going, so you're in luck!
