Managing VST plug-ins
Adobe Audition automatically starts the VST Plug-in Manager if a plug-in fails to initialize, but you can also use it to customize the use of VST plug-ins in Adobe Audition.
Disclaimer: The registry contains system-related information that is critical to your computer and applications. Before modifying the registry, be sure to make a backup copy of it. Adobe doesn't provide support for problems that arise from improperly modifying the registry. Adobe strongly recommends that you have experience editing system files before you modify the registry. For information on the Windows Registry Editor, see the Windows documentation or contact Microsoft Technical Support.
To manaully turn on the VST plug-in manager for customizing VST plug-ins in Adobe Audition:
1. Choose Start > Run.
2. Type regedit in the Open text box and press Enter.
3. Navigate to HKEY_CURRENT_USER\Software\Adobe\Audition\2.0\Prefs in the Registry Editor dialog box.
4. Open the VSTPluginMgr key, change the Value Data from 0 to 1 , and then click OK.
5. Close the Registry Editor.
6. Restart Adobe Audition, choose Effects > Refresh Effects List, and click OK to confirm the refresh.
7. When the VST Plug-in Manager dialog appears, choose which plug-ins you wish Adobe Audition to use.
After doing this, the table comes up and you select your vst plugins - great!
