One main tip I would give to you;
Make sure you have East Asian Languages installed, and Japanese Keyboard support/Locale switched ON.
Otherwise you will encounter more errors than usual, and you will not be able to use... well, a lot of things. Mostly Voice Banks and USTs.
Any Hiragana/kana USTs that were made by a japanese person will simply not work for you, although ones made on an English computer will come up with fixable gibberish.
You won't be able to use Teto, Hiyori, Ritsu, Ruko, Tei, in fact, most popular UTAU.
Their banks are in kana. |:
These are the main points as to why you should switch to Japanese Locale.
Don't worry, the only thing it will change is \ will occasionally turn into a yen sign, and the apple updater will be in Japanese.
^^'' Uh, Welcome to the fandom, by the way. Some things will come off as obscure at first, but hopefully you will get used to it all.
/really needs to upload FAQ soon
UTAU is less computer knowledge, more Musical knowledge.
c: It's pretty straight forward, and it becomes familiar after you work out the basic functions, and file types... what buttons do XD
I personally use Japanese UTAU, but some people have been using an English patch. Using this patch doesn't do anything to the USTs, or Voice banks. You still need Japanese locale.
All it does is Translate main menus. ^^
Uh... Well, you'll either start and love UTAU, or it wont work very well for you and you'll give it up...
So I'd say about 50/50 chance you'll stay interested. Depends on whether you pick up things fast, and whether you like the music, and if your compy can handle it. c:
