Tests results on Pro Tools 7 LE /UAD-1 compatibility - BUG?

[LuçaS.]

Im a Pro Tools LE user and i use UAD-1 plugins since the release of Pro Tools 6.4 - They've always worked well until it came out the LE 7.0 version.
I've bought almost all the plugins from UAD-1 and i do a great use of them.
The latency is not a problem for me, i work putting delay compensation in groups.

I have an Athlon 64x2 3800 with an ASUS motherboard, never had problems with my DIGI002 or UAD-1 cards, i've seen many user with this similar configuration.

As you probably know PRO TOOLS LE 7.0 is specific for use together with DUAL CORE CPUs, and that's why i chose PRO TOOLS 7, because i needed more power for the other plugins.

Since the day i used PRO TOOLS 7.0 i could never use the 2 Cpu option in the playback engine in pro tools (before that time it does not exist). The main problems is that pro tools stop after few seconds after play.

I really didn't know if it was a pro tools bug, a VST to RTAS bug or UAD-1 plugins bug, so i did some tests and observed this:
- without .dpm files in the pro tools plugins folder it works correctly (so i realized that it is really a plugin problem)
- with other native plugins (then with the correspondent .dpm in the plugins folder) Pro Tools works well using dual core
- with other wrapped VST plugins Pro tools work well (so i can exclude a wrapper problem, however i have the last version 2.1)
- with any UAD-1 wrapped plugin i get the problem: i push PLAY (o REC) in Pro Tools and it stops after few seconds (they can be from 10 to 30 usually)
- so to be sure of this, i tried many times to put a .dpm wrapped file of PULTEC or Cambridge or EX-1 and i saw the problem as i put the correspondent plugin in the insert of a track. As i move the dpm file and reopen pro tools the problems go away: it's a UAD-1 bug, they don't support the dual core

So i can't use the dual core, and i can't use a lot of plugins only for this problem: i would not to sell my uad-1 cards but i could improve my processing power without latency problems.

I would just know if UNIVERSAL AUDIO is doing something to fix these problems which seems to be really heavy for users which in the last year chose to buy a dual opteron or machines with a lot of processing power instead of buying DSP card such as UAD-1.

There is another problem: people can't use uad-1 plugins without its DSP card, so if there are others users in my conditions maybe they can think to sell UAD-1 DSP cards and change plugins

I THINK THAT THEY HAVE TO FIX THESE PROBLEMS
But are you doing something on these problems?

Not necessarily; it's a user-run, un-official forum.

Hi,

I've read your post twice and I would suggest that the problem is more likely to be with Pro-Tools LE 7. Considering the only change on your system, according to your post, has been the upgrade to PTLE 7 and 6.4 worked fine, it would seem logical.

Of course I could be wrong. As Akis says this is an unofficial forum. You might find better help emailing UA and Digidesign.

BTW, Pro-Tools isn't the only audio application that is designed to work with multiple processors.

Yours,
Mark

But PT 7 LE works fine with all wrapped plugins, except for Universal Audio ones... in my system which is a dual core-based system. And i have problems with UAD plugins only setting to work the 2° CPU on my PC.

Of course I could be wrong. As Akis says this is an unofficial forum. You might find better help emailing UA and Digidesign

Ok, so i'll write to Universal Audio (do you know who could contact?) and DIGIDESIGN

Hi, good morning,

I still wouldn't be 100% convinced that it's the UAD plugs that are at fault. You could try something like downloading a demo of another audio app (that's multi-proc capable) and see if that works with UA on your machine. UA plugs are working fine on my dual proc machine, so I doubt it's anything to do with dual proc/core.

Of course I could be wrong. As Akis says this is an unofficial forum. You might find better help emailing UA and Digidesign

Ok, fair enough.

what could i try? what do you suggest me?

Hi again,

Well, I think Sonar and Samplitude both do downloadable demos, although I've read quite a few reports of Sonar having some VST issues. So, Samplitude may be better for this test. Personally, I use Cubase SX3 without any problems on dual proc/VST/UAD but they don't have a demo unfortunately.

Yours,
Mark

same problem here
on M-box 2
try to change latency from youre 002 to at least 1024
it will work i think - of course its ridiculous but only use for mixing??

im really pissed off about it too

if you got answers from Digi or UAD please let us know!!
