UST's not making sound

[Refringerator Raider]

Hello everyone, I'm having a weird issue. So the utauloid I'm using (teto) is making sound, but it refuses to recite any usts, no matter if it's hiragana or romaji and I'm using the default resampler. I eventually figured out this was an ust specific dilemma due to a test where I made teto use a few sounds, saved it as an ust and then it no longer worked. Does anybody know what the error could possibly be?

Have you fit the UST?

There are 4 buttons in the upper right corner of the toolbar in UTAU, make sure you are in Mode2 (click Mode1 to change it)
The buttons are ACPT, P2P3, P1P4, OPT, and RESET, (could be in a different order)
To fit a UST to a voicebank, press these buttons in this specific order, RESET, ACPT, P2P3 then ACPT.
If that doesn't work, you could change your locale to Japan

Ensure that the entire UTAU folder is outside of Program Files, as well as the location that you're saving your UST.

To fit a UST to a voicebank, press these buttons in this specific order, RESET, ACPT, P2P3 then ACPT.

This particular sequence of button presses has often been repeated without good reason, and is unnecessary when you understand what the buttons actually do. To quote my previous post:

These five buttons are for quickly editing the envelopes of the currently selected notes. You can hover over them to see a longer description of what they do.
To view note envelopes, make sure that the [~] button in the bottom left corner of UTAU is pressed. These shapes represent the volume of the notes over time.

ACPT (Apply automatic parameter adjustment) will copy the preutterance and overlap values from the voicebank's configurations into the note's properties. Sometimes, when the previous note is very short, the STP (starting point, a value added to offset), preutterance, and overlap will need to be automatically adjusted in order for all of the notes to fit together and all stay in time. Those adjusted values will be applied to the note properties instead of the original values in the oto.ini.

P2P3 (Set crossfade envelopes by p2 and p3) will adjust the envelopes so that the beginning and end of each note will fade in and out, rather than start and stop abruptly. By fading the volumes between the notes, they can blend together more smoothly during the part where the notes are overlapped. You will notice here that the first and last points of the envelope are in the bottom corners. If you decide to edit the envelopes, this makes it easier to make the volume cut off entirely at the beginning or end.

P1P4 (Set crossfade envelopes by p1 and p4) does the same thing as P2P3, but the first and last points are used for the top corners of the envelope. If you decide to edit the envelopes, this means you have more points in the middle for creating volume variations throughout the note.

OPT (crossfade optimization) will adjust the STP of each note slightly based on the previously played audio, so that each note blends together a bit more smoothly.

RESET (Reset envelopes in the region) will reset the envelopes for all selected notes to default. If you used ACPT or OPT, or if you're using a premade UST where someone else might have used ACPT or OPT, and especially if you're now using a different voicebank, you should also check the region properties for the notes to make sure that Preutterance/Overlap/STP are erased.

When using a pre-made UST, you need to ensure that the note parameters are not based on the old voicebank.
1. Select all notes, right click, and go to region properties. Erase Preutterance, Overlap, and STP. UTAU will now use the OTO values from the current voicebank. Then you can reset the envelopes.
2. You can choose whether to press P1P4 or P2P3. You only need to press one in order to crossfade the notes.
3. ACPT is generally unnecessary unless you're completely done editing the lyrics and you really need to see the exact values of Preutterance/Overlap/STP for every note.
