Just a heads up for anyone considering buying the Eventide H3000 Factory Plugin.  

When you reload the project the plugin does not work until you reload a preset.  They are working on the problem but currently the best workaround is to make ANY setting you use in a project a preset and then reload that preset manually every time you open the project. 

The latest from Eventide...

"I have been able to reproduce the issues you're having with Sonar.  This problem is actually different from the issues that we were seeing in Cubase, and we don't test against Sonar in house, so we didn't see this one.  I'm looking into it and will let you know when I have some more information."

I just wanted to let everyone know that the bug that prevented the H3000 plugin from working with Sonar has been fixed in release 2.0.6 that was posted yesterday. Everything appears to be working correctly and sounds great.

This is a similar problem as the one I'm having with certain Native Instruments effects. I use a NI compressor on the master bus that will not do anything until I "kick start" it with a preset. I believe it is also an incompatibility issue with Sonar because I used the same plugs in Pro Tools all the time without problems.
