English Miku sounds like shit.
I don't get why english producers don't just use Gumi or the english vbs instead. The worst part is that even the jp vbs sound better at english than the actual english vb.
At least Teto SV sounds ok in english despite most songs having almost the same tuning. I hope that we get a Luka V6 since she was supposed to be the bilingual vocaloid, but a decent V6 english Miku would be nice
