x and Y flags not working in default resampler?

[No Qualia]

Hello. I find myself using the default resampler (the one that comes included with the original UTAU) a lot, so I thought it would be good to check what flags I can use with it so I know what my options are when using it. I've figured out how some of them work and what they do, but there's others that don't seem to do anything no matter how hard I try, the x and Y flag.

It says they're valid flags for the default resampler on the wikidot UTAU wiki, utau-bowl's blog and also on this forum (they also appear here for what that's worth, but it's not default-resampler-specific), so they must do something, but they don't. I've tried both in the original UTAU and in OpenUTAU, and on several different voicebanks, but it's all the same. I'm also checking the waveform just to make sure it's not just my ears not working, but the waveform doesn't seem change one bit either when I modify the x or Y flags values, whereas for the other flags I can see the change just fine. The closest I've come to making one of them work was replacing the "x" with an "X", which does do something, but it doesn't seem to be the same thing and I doubt everyone has somehow made the same mistake of using lowercase x when they meant uppercase X in any case.

Just in case it helps in any way, here's a recording with Teto's CV voicebank in the original UTAU using the default resampler it comes with, changing the value of the x flag.
I made one part with no flags and the other two with the minimum (x-100) and maximum (x100) values of the x flag.
And here's another recording done in the same way but changing the value of just the Y flag (one is Y100 and the other is Y0).

Does anyone know why these flags won't work? Are they flags that only worked in previous versions of the resampler, or do they need something specific like i.e. another flag to work? Are they just that subtle? If they work for you, would it be possible tell me what you did, and maybe upload an audio where you can hear difference so I know what I'm searching for?

Thanks in advance.

I decided to try out the resampler versions I have to see if anything changed with these flags, and wouldn't you know it- You're absolutely correct that Y and x don't seem to work on the current version of resampler.
Meanwhile resamplers 10 and 2010 work with the x flag, but not the Y flag.
Then resampler 8 works with the Y flag.

Here's examples of what they're supposed to sound like:

resampler10 x-90 and x90


resampler8 Y0 and Y99 (pretty subtle, but you can hear the breathier vowels in the Y99 portion) [NOTE: resamp8 doesn't like consonant velocity, so it's generally best used with CV voicebanks from my observations]


I'm not sure why these flags don't work/may have been removed as functionality, though it's interesting to actually look at the current resampler alongside the older versions since I grew up while UTAU was still in active development and never really registered that there were any changes in how the flags did or did not function in the default resampler.

I won't rule out that maybe a certain combination of flags could make them work again, but I'm also not holding my breath that they weren't just flat out removed for one reason or another (likely their functions being usurped by other flags like b and h for Y, then C, D, and E for x).

Ooh, that's interesting. I hadn't particularly given much though to how the default resampler has evolved over time either, but it's nice to be able to look back and see. Maybe I'll try getting my hands on these too and fiddle around with them, it could be fun...

In any case, thank you very much for your reply! It was super helpful.
