Sound missing in OpenUtau?

[Melody]

Hi, recently I've been doing a SIU cover with Gekiyaku, but the sound seems to cut off as some parts. For some reason, it's only in the parts which use a softer voice, but I don't know how to fix this, help pls.

Video for example:
(I'm using OpenUtau if that helps)

You gotta show the piano roll so we can see what the phonemes/lyrics/expressions are doing. Are you using voice colors or just editing in the suffixes manually or was this a premade UST?

First of all: Yes, this was a premade UST by Mimisan 15. Second: No, I'm not using voice colors. Third: I'm not even using That voicebank's suffixes, I'm just using the regular notes.

It's probably an issue with the straight vertical pitch lines. Move the pitch points a bit left or right so they form a slope.

To be specific, right where it cuts off you can see there's a corresponding vertical pitch snap. This issue can happen at specifically timed pitch snaps, unfortunately, to rectify it you can either wiggle them left or right a little bit, or make them form a slight slope instead of being perfectly vertical.

Thanks! This really solved it!
