hi there. i quit utau for a while and im back now. i had this issue a lot back then and i never solved it, but basically sometimes when I use certain UTAU and import them into the program, the prefix map becomes blank. Even though the utau does come with a prefix map(i checked the files and stuff). So basically the program won't render any notes and i can't use the UTAU. sometimes if im lucky the problem gets fixed if i just redownload the UTAU. i usually try to fill in the prefix map manually but then it doesn't save even when i click the write button or save the ust. it gets annoying when you try to use banks with a lot of different pitches and stuff. i've had this problem with gekiyaku, number bronze, and gahata meiji. with number bronze and gahata i remember i tried to redownload them back then but it didn't fix the problem. gekiyaku was a hit or miss. does anyone know how to fix this? thanks in advance.
