UTAU 4

I'm having a weird timing bug when running UTAU in Ubuntu 20.04.

I'm new to UTAU, so I can't describe the problem perfectly, but it seems that when generating a .wav with a VCCV voicebank, all notes are shorter than their target length by some fixed amount, especially syllables that begin with vowels. For example, with the voicebank CZloid, [da] is shorter by 0.04 seconds, and [an] is shorter by 0.15 seconds. I don't know if it affects any other kind of bank, but on VCCV it’s especially noticeable because complex syllables are built from very brief notes that represent transitions between phonemes, and each of those notes is shortened individually. I can confirm that this is an issue with either PlayOnLinux or Wine, because note durations are fine in Windows.

Here's a minimal working example, and its generated audio on Windows and PlayOnLinux. All notes in this sample should last for exactly 0.50 seconds.

Its coming along nicely, but the menu is glitched and does not show the actual Japanese.It's replaced with hese random boxes, and I have no idea how to fix it. Can you help at all?
