New mac pro's and UAD-1e ? any problems

[cane creek]

I was reading a thread on a forum that a guy was having all types of problems running 2 UAD-1E's on his Mac pro just cant remember where i read it.

I was wondering if this problem has been ironed out , as i have a Mac pro & want to buy 2 UAD-1E's.

I have posted over at the UAD-1 forum however had no replys.

I've got 3 UAD-1e's in my Quad 2.66 and it's fairly good with Logic, but not bulletproof. I find that I cannot run the UAD-1e's very hard without errors of some sort, being it error messages or crackles, etc... This is when pushing the 3 cards together up to about 50% or over. My work around is to freeze as much as possible to free up resources.

Not perfect, but I love the plugs and use them daily... I also had issues with the higher CPU plugs needing audio to hit before they started processing, so you have to make sure you aren't doing super tight edits on those tracks with those plugs on them. The ones that were really freaking out where tracks with Precision Multicomp on them. Not happy with sound just instantly hitting them. The solution was to just roll a few seconds of dead air audio before the sound starts on the track.

I hope this helps a little.

Ive got one and pro tools, no problems at all for the moment. Only errors I get are self inflicted because of DSP power maxing out.

I'm going to be installing a UAD-1e in my early 2008 Mac Pro this Thursday; I'll report back then. PM me if I forget to post.

I'm running 2 UAD1e and a Symphony PCIe on a new 2.8GHz 8-core. No problems in logic 8 or cubase 4.

Well, I've spent a couple of days struggling with it but I'm about ready to admit defeat; I can't make my UAD-1e card do anything useful in my early 2008 Mac Pro.

(Logic Pro 8.0.1, OSX 10.5.2, 8x2.8)

I can open one lightweight plugin (say a single LA-2A) on a track, and it plays, but I get lots of pops and clicks. If I do something really silly like try to open a second plugin, I get a loud buzzing noise then the track goes silent. Bypassing the UAD and restarting the song makes it audible again.

I've tried every tweak in the UAD configuration and every combination of buffer size and other driver option I can think of. Nothing makes any difference.

YMMV.

What audio interface are you using?

It sounds like an issue between PCI-e and Firewire, as the PCI-e Symphony works fine.

Did you have the problem on both the FW400 and FW800 ports? I believe they are independent chipsets.

I don't know much about macs but I assume it's a dual or quad...If so have you tried turning off multicore support and just running it on a single?

The reason I ask is that's the only way to get my uad-1 cards to run in Reaper on a PC. It's a bit of a bummer running on one core, but the other core is still available of OS stuff

[r.staettler]

im an an intel quad 2,66 w/ two UADs (PCIe of course) and a motu 828mkII (fw)

no problems here even when maxing out the cards if the buffer ist high enough (500 or 1000!)

for playing instruments i ve put logic 8´s new low-latency-command on a key: press key / record midi / press key again / mix... works great

I don't think that's an issue with the UAD-1, as I am running two at 96k with an 8-core mac and symphony at it's lowest (32k) buffer setting. I think the problem is a conflict between the Firewire and PCI-e bus.

I would contact UA. They've always been responsive as far as tech support.

[mattkalin]

the only problem we're having with running uad-1e's in our mac pro quad 3.0ghz is there are only 3 pci-e slots! we would have liked to max out with a fourth.

[mfender]

I've contacted UA support; I'll post back if I hear anything.

I was definitely suspicious about a firewire conflict, but I get the exact same problem if I use built-in audio, so I'm not convinced.

Also, enabling "force logic to use live mode" makes no difference at all, and that should supposedly force the plugins for a track onto a single core. So I'm not sure it the multicore aspect either.

Don't know what it is. I'll wait for UA. In the meantime I guess I should demo some native plugins to replace the UAD... that is going to be a very tall order...

It sounds like we have the same system, and I was able to use the UAD-1 with the built in line out before my Symphony arrived, so I think it's something with your configuration.

Did you try reseting your computers PRAM?

Also, I had a problem with some updates not being applied through software update. Specifically "Pro Applications Update 2007-1 and 2007-2", which I ended up downloading directly from the Apple site.

[mfender]

I hadn't tried resetting PRAM, but I just did. Didn't help.

I have all of the updates (I had to apply Pro Apps 2007-02 manually as well).

I saw the following messages a few times this morning when trying it again:

"A plug-in seems to cause problems running in Multi Processor (Multi Threading) mode (Pultec Pro)"

I get a similar message with whichever UAD plugin I try (in just a one audio track test project with no other plugins)

I'm about to try what I consider my last resort, which is to pull the card out and stick it in a different slot. After that I'm done with it; I need to mix today. Quite how I'm going to do that without my Plate 140 is anyone's guess, but at least Altiverb is working!

That's a UAD & Reaper specific issue.

Yeah try another PCIe slot, might be some conflicts.

I'm getting either a iMac (which I'll sell my UAD's and get a Duende if I do) or Mac Pro (and will keep the UAD's) end of next month, so I'm watching this with interest. I just started using the Precision Bus Comp (and loving it as well), I understand your feelings about the Plate 140, just sounds ace!

Good luck

No not just Reaper. Sonar, PTLE etc users also have issues with multicore. Check out the ChrisMilne forums.

Having said that, there are reaper, sonar users running uad-1 plugs quite happily on multicore.

mfender it's actually very hard to pin down what the problem is from an end user perspective. People with seemingly identical systems and one will work and the other won't.

The reason will be some obscure driver that probably has nothing to do with audio processing, or a funky bios version, or just the fact it was raining the day you installed the card. Have you tried asn older version of Logic?

Well, this is a new machine that I wiped and installed only my audio software on (including Logic 8). I really don't want to install Logic 7 as I don't intend to use it and want to keep the machine as clean as possible. I'd rather live without UAD than go back to Logic 7 at this point.

BTW - putting the card in a different slot didn't help. Just waiting for UA support at this point. Thanks for everyone's suggestions so far.

What version of UAD Drivers are you using, have you tried with any others?

Have a look over at the UAD forums might get some more answers there.

Actually sorry you're right. I have both Reaper and Sonar 7 PE and some are having issues, I did not encounter anything major with them but haven't really done a full mix with plugs, just a couple instances. My main DAW is Logic win 5.5.1, which I use on a Quad PC with UAD with no issues.

I'm using UAD 4.9.0. Older versions are not Leopard-compatible so haven't bothered trying.

I have posted on the UAD forums too.

Hey...

Im running a brand new Mac Pro 2.8 8core with Logic Studio and an Apogee Symphony card and 2 UAD PCI-e cards and everything is working well. I can just about max everything out (even as low as a 32 or 64 sample buffer) before it starts to get sketchy.

Now... BFD2 still brings me to my knees, but I think that's a ram issue, as I still only have 2 gigs installed. 6 more are in the mail as I type, so I'm hoping that smooths it out.

Good luck!

Not sure what that means but I have 1 UAD-1e working on my new 8core Mac Pro and Logic 8. No problems so far. I was almost afraid to install it after reading some threads here and at the UAD forum.

[mfender]

UA support have stated that there is an issue with UAD cards on the early 2008 Mac Pro, and they are working hard to resolve it.

From the general responses, it seems to only be a serous issue when using FW interfaces.

There are some posts from UA on the UAD forums about it; they request that anyone having problems send their system profile info to their mac support team.

[wildstar]

Absolute nightmare on Quad 3.0, running OS 10.4.11, and DP 4.12. RME Multiface 2 & HDSPe card.

I have two UADe cards installed (and the HDSPE card.) Once UAD CPU usage hits 50% or so, I get non-stop stuttering, sputtering and spitting of audio. Horrible. Sometimes even after removing the UAD instances that pushed to 50%, the audio glitches continue and a restart is needed to resolve. When this happens with UAD, DP's CPU meter also redlines.

I suspect DP, as its CPU efficiency and usage have been and continue to be terrible. But it could be RME (though I feel this is unlikely,) or PCIe card slot placement. Or any number of things.

In the middle of a deadline-critical project, and haven't had time to properly troubleshoot or contact UA about it. Forget MOTU tech support.

Am SO ready to ditch this DP-based system and move to Nuendo on a custom-built PC.

YMMV

Cheers

[gastod]

in the sysinfo of uad instead of -OK- -OK- after 30 sec. show -norsp- -OK- and the card not work. before install the 4.9 driver card is not visible by SYSOP in the PCI slot, is this normal? it show only the VideoCard and after the installation the UAD is visible on it. but after +/- 30sec. the UAD-1 status is -noresp- and the DSP status is -OK- gas

Joe, what program are you using?
