Very New to UTAU! Please help. :<

I have the screaming thing, too. It's easy to make a crappy fix but I don't know how to fix it for real.

Let's say sometimes some notes just don't render correctly (I think it comes from using a not Japanese locale but I'm not sure). It's how UTAU works to me.

What i make to fix it:

Select All Notes (you can use Ctrl+W) in UTAU like normal and play them (F5).
Listen carefully and look for the broken note to appear, stop the song (F7) and select the broken note. Play it to check if that's the broken note and not one near it.
When the broken note is selected, right click on it and use the third option (Clear Cache). Then right click on that note again but now select the first option (Render and Play). Repeat if the note is still broken.

Now select all the song from the note you just fixed and continue checking for broken notes.


Previosly to fix it I used to change the pitch of the broken note, play it, make it back to the normal pitch and recheck if it was fixed... but the new method is faster and now I understand it does the same fix (clear the cache to try to render it correctly).

Also, somewhere I read adding any flag (even if it's so small it really doesn't matter) fixes it from the start.. but I don't like that option. *shrugs*
