I got an email saying that all the Plugin Alliance plugs have been updated and to download them.  Since I have 10 separate plugs I'm wondering (since I can't seem to find any info in the email or on the site) what's exactly been updated??  Anyone know??

Yup, Go to the PA site, click on 'Download' on the top menu, and each plugin will have a 'changelog' item. Most of them will show the same thing for Apr 5: Version 1.5 (Apr 05, 2013) - otimized performance - fixed issues with possible high CPU load - fixed Avid related issue in Pro Tools 10 that could lead to sporadic crashes - fixed issue that could lead to values jumping in Ableton Live

wow that is a lot of work, too bad there not all in one place.

It didn't really take very long since I only looked at the log for 3 of them and they all had the same changes (listed in the badly formatted post above). They probably updated common code an recompiled them all. A more time consuming hassle for me is reinstalling them. The install paths default to a folder that I don't use so I have to change 2 paths for each install (for the 32 and 64 bit versions). Since I haven't had any problems with any of their plugs (yet), I skipped this upgrade.

They still haven't fixed the problem with the Dynamic Spectrum Mapper retaining the curve in Sonar.  I have been in contact with them numberous times about it and they always lead me to believe it would be fixed, but that was two updates ago.

I like the DSM, but it would be way more useful if I would retain its settings!

That's happened here a couple of times too. I suspected it had something to do with closing the daw or project while the dsm window was opened but never got around to testing that theory.

For me the DSM will never retain the settings regardless of whether the windows was opened or not.
