UTAU renders wav faster than tempo setting

[Baka94]

Another issue I ran into today...

I noticed that UTAU rendered the wav files slightly faster than what the tempo setting is. The tempo setting says 165 BPM, but when I try to sync the vocals with the instrumental (temporarily have to use Audacity unfortunately) they get desynced even though the song is exactly 165 BPM. Anyone know how to fix this? Just like the last thing I posted about, this one too is an issue that I've never had until I installed UTAU on my laptop.

Check to make sure that 165 is the tempo for the entire track! If you look slightly above the piano roll, the tempo is also displayed there in blue numbers; it may display something other than 165 somewhere in the song.

There were no other tempo markers than the one in the beginning. The desync doesn't happen suddenly. It happens slowly over time and it is already a 8th note off within the first 40 seconds (approximately)

Sometimes when importing a VSQ or if using a UST made on UTAU-Synth, note lengths and rest lengths will either have extra super-tiny notes or be ever-so-slightly too long. It's a great inconvenience, but if there aren't tiny notes and the notes are just too long, then you can run a find+replace operation on the UST file in a text editor to bring those numbers down.

The issue can't be in the UST. I have used the very same UST before and there was no desync that time. I even tried generating a wav with a different UTAU (one that I know is a high quality one) and there was no desync. The only possibility now is that the issue is somewhere in my UTAU's VB.

Make sure that you are fitting the ust properly.
If not, UTAU may skip notes without warning and throw the vocals off-time.

Look for an [!] over problematic notes and check to make sure that all the notes are correctly played in fast and/or crowded areas.
Even if no [!] is visible, sometimes a note will encounter issues when rendering. Simply look for notes around/near the area that the vocals become offset.

If you find a note(s) that does not play, press ctrl+y to bring up the envelope editor and make sure that the points are not colliding.

I am assuming that you are already clearing the note parameters in the region properties window and resetting+crossfading appropriately.

 

[Baka94]

I haven't checked the parameters because the UST is not made by me. As far as I can remember there were no [!] marks when I fixed the lyrics to fit my UTAU. Do you think that the desync is caused by a short note begin "drowned" by the next notes preutterance (?)? It would make sense since this only happens with my UTAU and there are a lot of short notes.

 

[na4a4a]

When you use a UST that was previously used with a different voicebank, it is always good practice (if not absolutely required) to clear the preutterence and overlap values in the notes.
Since most voicebanks use different values, this will almost always cause notes to be out of time of unable to play at all.

A note shouldn't get "drowned" out by the next note's preutterence as long as the overlap is appropriate (with exceptions, of course)

Press "ctrl+a" (select all notes), then right click the notes and make sure the preutterence and overlap fields are empty.
Press Ok.
Then, with all he notes still selected, press the "reset" button at the top-right of the UTAU window to clear any envelopes and then click "acpt" to copy your VB's OTO values into the notes.
Then use p2p3 to crossfade the notes.

that should fit the ust, if problems still persist, then you will need to fix the problematic notes manually and I suggest looking at your OTO to make sure that that isn't causing any issues.

I can't see a "reset" button

EDIT: Never mind. I found it.

The four little buttons on top. With the pictures.

After crossfading some [!] appeared. there was a text that appeared at the bottom, but I don't know what it says:

 

[na4a4a]

Go into the envelope editor and click "normal" to fix any crossing points. Then make sure the note is playable

I do not know what that says as I never payed attention enough to look into it. it's probably just like "I did the thing you wanted yepyepyep"

 

[Baka94]

Okay, that fixed the issue. I think UTAU should have a tool that would change envelopes to "normal" for notes that have a [!]. Actually the whole sequence of actions I had to take could be done with a simple tool that calls the functions in a specific order (unfortunately I can't program in any modern programming language so I can't make one).

 

[na4a4a]

In the shareware version of utau, clicking the [!] will do something similar.

But instead of evenly splitting the points, it takes the leftmost ones and pushes them away.

But there are a few moments where neither work, so it's always good to take a look yourself.
