the entire fuckin ust is like this dude. im already so tired from changing all the lyrics for another cover to fit an english bank dont make me do this again PLEASE
you can use the surffixbroker in utau to remove the prefix letters before you import it, or if you use openutau you can crtl+a -> notes -> japanese vcv to cv. i hope this helps you
One day I was testing usts on synthv because I had a problem with it and I was thinking "There's no way it's gonna make sound I used a vcv with suffixes." And when I played it ust turned svp it sounded like "Slivimehifimehimeh" it was hilarious!
u can do what flamentnagel said in their comment to prevent this, and also if you use utaformatix for your file conversions u can change the target lyrics type from VCV to CV and it will do it for you
