How do you make the Mao Mao UTAU stuff?
Simple.
I used this as of tutorial: http://utau.us/cv.html
The first things first you might wanna know is the hiragana list, like a i u e o, ka ki ku ke ko or even sa shi su se so and so on. From then, I usually sentence mix him, not that really important unless you might wanna try make him say as japanese, but his accent is American so, lol.
3rd I render them out as of files and wrote down those hiraganas as filenames, not as the real japanese hiragana but went with romaji (e.g na.wav ne.wav nu.wav ni.wav no.wav)
Finally oto'ing, oh boy, what a pain in the ass to do this but you have to do it anyways in every file, at first I was confused on what the hell do I do this, but thankfully, now I understand, on the other hand I think the site might be useful for it oorr google'ing oto'ing is possibly the best part to do. And oto'ing is where you put constant, crossfading and possibly other stuff.
And now you can enjoy the black cat singing in to some japanese songs, but make sure to change region to japanese on windows (that is also pain it needs restart computer and so as if I want to turn it off then I had to restart PC again... 🙄)
Hopefully that helps it out.
