noisy UAD1 in G5

[deadskinboy]

i've had a G5 for a few months now, a dual 2.0....i just moved my uad-1 from my g4 to my g5, and the uad1 is acting very poorly. if i load one plug, especially a compressor, i get a slight fuzz in the left channel. if i load enough plugs to get the uad-1 meter up to 27%, everything goes to complete bitsmashed distortion after about 45 seconds of playback...

i am using an m-audio delta 44 and cubase sx 2.0. both were behaving very well until i added the uad-1 into the mix....

anyone have any similar problems or suggestions?

thanks

The M-Audia Delta series has had a history of problems with the UAD-1. I had to replace my Delta 1010. I got the RME Multiface and never looked back. it rocks! One way to see if it is indeed the Delta is to use you Macs AV out and turn off the Delta. If you don't get the distortion then you know it's the Delta44.

Just experienced this noise burst today, it's not pretty. Using the Mackie UAD-1 (software 3.5.1) with DP 3.11, OS 9.2.2, QS 800 DP. I've had trouble that was at least temporarily solved by simply reseating the card (last week). I just ordered a Project Pak, so I'm a little concerned.

mattdean, you are correct....it seems to be the delta....i switched to the built in card, and the uad-1 worked right. that SUCKS. i was very happy with the delta 44 until i tried it with the uad-1. i'll email midiman and see if they have any suggestions (i doubt it).

that multiface does look nice, tho a bit overkill for my needs....4 ins and 4 outs is about all i need....any suggestions? anyone have a audio interface that meets those specs and works well with a uad-1?

btw, i tried 3.5.2, it did not fix the problem.....

Interesting noise problem solved on G5 and MOTU DP4.

After tediously troubleshooting exactly where I was getting noise from with my new UAD Project Pack, it turns out that it is the LEVEL of the plugins themselves that were doing it. I didn't think it would be the plugin aux that was doing this since I was ONLY getting noise on the RIGHT CHANNEL (very strange, indeed!). I first ruled out my analog mixer by bypassing the signal straight into the amp. Then switched speaker sets, with same results. Then just monitored straight out of the 424. Bumped up the buffer to 1024, Still NOISE! Went back to the actual original song files with the UAD plugins BYPASSED. NO NOISE. It seems these plugins boost a level of gain that is very hard to see on your DAW's meters, but it is there, especially the Pultec Pro. I believe it is because of the added midrange warmth. I found this to be true using the spectrum analyser in Firium, an excellent eq plugin I use. I remixed these offending song files and made sure all levels were below 0 DB and limited with the Masterworks Limiter and dithered and low and behold, NO NOISE on bounces and playbacks.

I'm adding my 2 cents here since I see many people here are struggling with this issue on many different DAWS. I too had tried the \"fixes\" and the real fix FOR ME was simply paying much better attention to LEVEL.

Setup:

Dual 2G G5, MOTU 2408mk3, MOTU Midi Express 128
G4, MOTU 2408mk2, Midi Express XT
- networked
48 track analog board
DAT, 1/2\" tapedeck
DP4, UAD Project Pack, Assorted soft synths, plugins and of course, good old REAL synthesisers and REAL guitars & drums &...
:idea:

jetengine - so essentially you're saying that the issue has been resolved (in your case?)

Your setup is very similar to my own which is why I'm asking...

- yes, the issue has been resolved for me. I hope everyone else finds their solution as well. I use high-end mic pre's and I am very sensitive to any added noise in the signal chain, especially digital clipping, which is the absolute worst.

When I installed the UAD card, this noise was immediate. It turns out its a level problem for me.
