I can see what you mean. They REALLY do not sound great (but i still want them anyway lol)OKAY, for an unpopular opinion... The Meika's are seriously horrible to work with - Hime in particular. Hime sounds as if they went through 700 rounds of EQ before they even made it to the synth. Mikoto just feels like they're lacking in quality, especially when compared to Gynoid's previous voicebanks.
Ok now for some of my personal opinions
-i think the way that Miku and Nana mispronounce some English words is cute
-they shouldn’t have discontinued Nana’s V3 banks
-yamaha should’ve kept their boxed vocaloids.
-(I don’t have V5 yet so forgive me if this opinion is already implemented) Vocaloid’s tuning system should be like UTAU’s: Simple, clean, and easy to learn
