Ok, With the person that said vocaloids make your ears bleed:
You have the wrong idea. There ARE fanmade vocaloids and UTAUs that DO suck. Real vocaloids include MEIKO, Miku, Len, Rin, Kaito,Luka Etc.
Hear the diffrence.
FANMADE/UTAU:
This is a fanmade one. It SUCKS BECAUSE A NOOB MADE IT. Warning: Its extremly loud and ear bursting. I advise you listen with barley any volume and DONT make this your first impression
However there are few GOOD fanmade vocaloids, or vocaloids that werent approved:
REAL vocaloids:
First, There are some clips from there game PROJECT DIVA (A smaller version of PROJECT DIVA is MIKU FLICK from the app store for $14)
Here are some normal videos of vocaloid:
This is an example of a male. vocaloid, Len kagamine.
This is the female version of him: (Note this is not the normal form, she wears diffrent clothes for this one)
So there is very bad vocaloids, but most are good. ~Sorry for bad spelling XD Oh and the girl with the pink hair is misplaced, she is LUKA and the one below her with the blonde hair is the opposite of the male.
