SONAR X2a has introduced a new mechanism for naming and referring to VST plug-ins throughout its menus.
VST Plug-ins are now referred to by their VST Plug-in Name versus the name of the DLL. While ultimately a more desirable behavior, this could potentially create confusion when trying to locate plug-ins that do not adhere to the VST specification's proper naming conventions.
Given the case, you have a few formatting choices for how to display the VST name in SONAR. This is controllable via a new .ini setting. To change the setting, you will want to add a new variable called VSTPlugInNameFormat via Edit > Preferences > File - Initialization file.
You can set the value to either 0, 1, 2, or 3.
0 - Format 0: VST supplied name
(this is the new default setting in X2a onward)
1 - Format 1: DLL Name
(this is the old behavior prior to SONAR X2a)
2 - Format 2: VST Plug-in Name (DLL Name)
3 - Format 3: DLL Name (VST Plugin Name)
After clicking [Set] you will see the setting show up as shown in the image below:
After you create the variable, restart SONAR and the menus should display the new naming format.
