Put a Fairchild emu and a 1176 , unless you're crompressing or driving , same sound at the end (distortion reacteration apparts)

May i ask your monitoring method ? do you have a goniometer or some to corroborate waht you're saying ? What setting do you put the UBK 1?

Jeezo I'm not talking about slight changes in the stereo image which most compressors introduce.
I'm talking about a hard panned signal moving almost completely to the center in the stereo image.

I know this might not be the best test, put I've done the following things to verify this:

1 - Created a hi-hat line, hard panned left
2 - Inserted UBK1 on the hi-hat channel
3 - Inserted PAZ Position (Goniometer) @ 2bus
4 - Turned on all the 3 modules on the UBK1, all working reasonably (meters moving)
5 - Signal didn't went center and stayed hard left


In my experience, most compressors (analog and digital) will shorten the stereo field when operating in "linked" mode. Use dual-mono instead of stereo link and the problem is solved. You can easily hear this on Vertigo SC1, Elysia Alpha and Paul Frindle's DSM, which all have linked/unlinked modes.

This sounds like a bug that's peculiar to your system. It definitely does not do what you're describing with Cubase or Wavelab.

I'm still pining away for the 64 bit update though

It cannot be clearer :

Stereo preserve of course ......check your set up ...

Ha,ha I actually have not even tried the UBK yet. Was just speaking in general that some compressors preserve the stereo image better than others given the same amount of gain reduction. What I was talking about would not be a huge difference like Dr.Gunjah described. Maybe something odd with his setup.

[Jeezo]

yep i think so ....

UBK-1, VCC, Softube, Altiverb, Lexicon, DSM...just to name a few......isn't that enough to convince you to get an ilok?

IMO, the DSM and/or the UBK-1 alone are more than a good reason to get one.

[Dr.Gunjah]

Ok, good to know that this is not a global problem and probably only a bug on my system and/or reaper.
I will try to reproduce this in wavelab.

cool keep us informed ...it might be usefull for other reaper ubk1 user ...

It's working fine here in REAPER 4.22 32bit (and 64bit, via bridge).

I don't think it's a bug, it also does that here in Reaper 4.22 and Sonar 8.5.3. But I think it's intended behaviour. It's basically acting like some kind of dual mono compressor.

If you set the LINK control of PSP's Mastercomp to 0% (which unlinks the sidechain signal for left and right), a panned signal (NOT hard panned!) also shifts towards the center the more it compresses - just as UBK-1 does.

Hard panned sources (100% left or right) won't shift, because there's no signal energy in the opposite channel, where it could shift to...

I can't conduct a test right now since I'm not at the studio, but like I've said before, I mixed a song last weekend with the UBK1 on the drum bus and didn't noticed such behaviour.

Anyway, I'd do a test later tonight to double-check this.

Doc, this is definitely not normal behavior and I can't replicate it over here, but I apologize that you're getting this weirdness and I'd love to get it sorted out asap.

Can I trouble you to report this as a bug to n-a-t-h-a-n-AT-k-u-s-h-a-u-d-i-o-DOT-c-o-m? He'll need your OS, CPU, DAW & version number, and UBK version number, then he can submit it to the coder and we can get to work on quashing it.

Thanks so much!

confirmed.
Tried it with compassion in unlinked detector mode and autogain ON and the behaviour is almost identical to the ubk1. thanks fripholm.
So i think my issue is not a bug, but based on the detector design..

@gregory: Is the assumption correct, that ubk1 (or at least the compressor) is a dual mono unit? If so, is there any chance to get a linked mode?

Cheers,
Doc

Guyz , tried in right now in sonar 8.5.3 and x1 ...no issue , for real ..hard panned to 50% ...nothing !! Beyer DT 990 PRo here where just a 2% pan change can be noticed ....**
Tried it on a mono track pan , a stereo track pan , a sterero track with intreleaved uncheked ..same ...

Jeezo, try this: Insert some kind of dynamic pad sound or slow piano loop on a mono (!) track and pan it 70% to the left. Route this track to a buss and insert UBK1 on this buss. For best results make sure UBK1 is heavily compressing the signal and the needle is swinging back and forth.

You should now be able to hear the mono signal wandering around the left side of the stereo field. I can clearly hear it and if you want visual approval, take your favourite stereo vectorscope (Ozone has one or Digicheck if you have RME hardware) and see the signal shifting around.

It's not a problem for me, you just have to keep that in mind...

[Dr.Gunjah]

It was an incorrect statement in my earlier posts, that it also happens with hard panned sources.
Like fripholm wrote in his first post, it doesn't happen with a 100% panned signal; you need some signal on the other side. I guess that's the autogain which increases a very low signal, but it can't increase "nothing"

Cheers,
Doc

I stand corrected. I just replicated this in Cubase 32 bit. It only seems to happen if you put it on a buss (a "group" channel)

Again, I'm not using UBK-1 much yet since I have a gazillion existing 64 bit projects...

The compressor is perhaps reacting to left and right independently.

If you want to use this on a stereo buss without side with the lower level increasing in volume relative to the other you'll have to create two panned mono busses each with a UBK-1 set to compress the same way, then create your image by manipulating the faders. Of course, if the information is dynamically different to a significant extent (like, for example, if you were trying to compress any sort of drum buss) then you'd still get stereo image changes that you probably wouldn't want.

Offhand, I can't think of a good work around for that - aside from rendering the material on the buss and importing it into the project on a new stereo channel track and instantiating the UBK-1 on that - obviously not an ideal solution :o)

Confirmed on win 7 64 bit Reaper...but! It seems to me to be the natual action of the comp as friphom and dr gunjah suggest.
This behaviour doesn't happen with DC8C for example.

It does when you put dc8c in expert mode and set channel seperation to maximum. Now when you drive the comp hard and then compensate the output manually (because it doesn't have an autogain feature) you get the same stereo shifting.

A linked mode in ubk1 would be cool, though I guess the question then is, what signal you feed into the detector.

Cheers,
Doc

Then why does it not happen when put on a Cubase channel track as opposed to a group track?

It's a bug.

[Jeezo]

Guyz , i will check asap (planning atravel right now , so not a lot of time) , but as you can see i my videos , i use UBK1 on a drum buss treating a whole drum kit : nothing on the panning .....except the pshycho acoutics effects !! (IMAGING)

Maybe because panning usually happens after the FX inserts.

Ahhh thanks Doc. Now all this being said, I've never noticed this behaviour before and it certainly has not affected my mixing or mixes in any appreciable way.

Confirmed !!!
from 10 oclock to 3 oclock WET ....

The drive module do do nothing ...the comp module is the most impacting , the density is also affecting but in a smoother way (unless you go real thick (in the red) ...

[Mercado_Negro]

I tested it in REAPER 4.22, following the steps you've mentioned here, and I can confirm this now. Yes, it looks/sounds like UBK-1's compression stage operates in "unlinked" mode, i.e, dual mono.

I made a video (.avi) showing this:

UBK-1_Compression_Behavior.avi (2MB)

I think we've just found out part of the reason why the UBK-1 adds movement to the source

I don't use too much compression with it, that's problably the reason why I never noticed it.
