Berhane: You will need to scan your plug-ins in sonar. The easiest way to do this is in the options menu in the VST tab. Make sure that the path where you installed trilogy is included in the list of folders to be scanned.

I put the folder under the VSTPlugins of Sonar. But, I couldn't access it when I am in sonar. Any help how I can use it? Regards, Berhane
