Hello All and thanks in advance for taking the time to read this.
My 2 UAD-1s work fine all day long - I can mix for hours with no problems. As soon as I try to export audio mixdown, they all crash. I get an error message saying “Sorry, one or more UAD Powered Plug-Ins have been disabled. (err=21)”
At this point all of the plug-ins no longer work - and the UAD-1 cards themselves actually don’t even show up as being installed(!) until I restart the system. It is impossible to mixdown, even in real time.
I’ve read about the same exact problem on the Cubase and UAD forums, where a response from UAD says that the problem is limited to Vista and UAD-2 only - Not so! I am running XP SP3 with UAD-1s.
Some folks mentioned in those forums to uncheck multi-processing within Nuendo, try raising the sound card’s buffer settings, and to try limiting the UADs CPU load to 95% - but all of this does not help.
This only happened after I upgraded to N5 (5.1.1) - I still have no problems when I use N3. It also appears that it only happens when I start running more than 10 UAD plug-ins or so - but that’s kinda ridiculous since I have 2 cards and they’re not even showing a 40% load. Track count doesn’t seem to make much of a difference - the song that I’m currently working on which wont export is only 25 tracks.
This is a real deal-breaker for me - I would like to stay in N5, but with my mixes I usually wind up relying on the UAD’s quite heavily.
