I have a Roland VP770 which I love, but NOT because it sounds authentic. In fact, vocals can sound pretty lousy unless you do a LOT of tweaking. The VP7 is MUCH worse and doesn't have all the other POSITIVE features that makes the VP770 still desirable despite it's less than stellar VOCAL HARMONIES. Of course I realize you're looking for a MODULE, but just re-emphasizing DonM's comment on the VP7. I have a ten year old TC Helicon that sounds (much) better. Wouldn't recommend (the VP7).
