User blog:Ajkpinky/Quick question about E.V.E.C.

With the V4X updates for Miku and the Kagamines coming around, I've been hearing about "E.V.E.C." a lot. I know it was used for Luka V4X, but all it says on the page is that, and I quote, you can "vary the vocal expression on each note, adjusting the power and the softness of the enunciation." That all sounds well and good, but many people seemed to be complaining about it on Miku's "electro saturator" demo. Could someone please give me a little bit more explanation about it and why there are complaints, if it's not too much trouble? Thanks. :33
