Regarding Genos vocal processing, Yamaha must have updated it because it sounds as good(dare I say better?)to me as the TC Helicon.
It might seem that way to your ears but
"as good as a TC Helicon"? 
I cant even imagine that unless they gained technology from
TC Helicon themselves and incorporated it into genos which I doubt,.........I would have to actually hear a
A/B VH comparison with my own ears to even give that a consideration,.....sorry..
secondly power singing tracking would also have to be auditioned in person.....
