UAD LA3A Smashes Up Some Drums

October 24, 2007
LA3A Screencast

Being a faster circuit than its cousin the LA2A, the LA3A excelled at different tasks. Although it was still a great vocal limiter it was also widely used on different sources, most famously percussion. UAD's emulation also performs well on drums as we will see in this video. Check out this screencast where Dan will run a drum loop through the device and try some different settings.

LA3A & parallel/bus compression

By: Billy Buck
Hi Dan, I enjoyed the LA3A screencast. I do have a question though. Are you sure that the "plugin delay compensation" parameter is enabled in the LA3A's VST Properties page, in SONAR? I have had issues in the past where SONAR did not automatically enable it by default. I wondered why I had delay/phasing issues when using some UAD-1 plugins, until I discovered that the PDC parameter was not enabled. I have had to manually enable PDC for some UAD-1 plugins, when using SONAR, in the past. SONAR has full auto PDC and putting the LA3A on a bus should not cause any PDC issues. Also, the issue with plugin defaults being out of whack when first opening some UAD-1 plugins (LA-2A had this issue as well), I believe this has been fixed in SONAR 7.01. BTW, the LA3A defaults properly (Gain @ "5" & Peak Reduction @ "4"), in REAPER 2.007. Doing parallel/bus compression is fully delay compensated, as well. A nice vocal dual compression trick is to use the LA2A followed by the LA3A (in limit mode). ;) Cheers, Billy Buck

Thanks for the awesome

By: dan
Thanks for the awesome comment. I went in and individually enabled the delay compensation. After restarting Sonar the problem was fixed. I did encounter another problem though when attempting to export though. I would get a strange clipping noise on the exported file that was not there when playing back in Sonar. Turns out that there is a Sonar Compatability option in the UAD properties, under the UAD-1 Meter application. When that is turned off the problem goes away. Strange. I will address both of these issues in a future screencast. Thanks again.

Yes, the new UAD-1 SONAR

By: Billy Buck
Yes, the new UAD-1 SONAR Compatibilty mode is meant to address a long standing "native cpu munching" issue, during playback, when using a lot (more than 5 or so) of UAD-1 plugins in SONAR, on tracks & buses. It totally solved the native cpu munching I would routinely get in SONAR, but it did have the side effect of introducing gapping/distortion in a mix render. This typically affects those of us with multi-cpu DAW setups. As a workaround you can disable the SONAR compatibility mode from the UAD-1 Performance Meter when exporting your project. The latest SONAR 7.01 update has fixed this. This is now a parameter you can set in SONAR's aud.ini that addresses this issue automatically when rendering so you can just keep the SONAR compatibility mode enabled now. Cheers

I see. That makes sense. I

I see. That makes sense. I don't have any trouble with CPU munching on my dual core intel system. Thanks again for such helpful feedback. I finally ordered S7PE and will start a series on that as soon as I get it.
