This document can help you to resolve effects plug-in problems including (but not limited to) the following:

-- Adobe Audition won't start (that is, the splash screen freezes when scanning VST plug-ins).

-- Adobe Audition freezes while "Building Workspaces" is displayed in the splash screen.

-- VST Plug-ins are missing from the Effects menu in Audition.

-- Error: An Error was encountered processing the VST effect [name of effect].

Support policy

Effects plug-in support is limited to the VST (and XFM) plug-ins that are included with the Adobe Audition 2.0 installation and the VST and DirectX technologies as they are implemented within the application. Adobe technical support does not support problems due to the use of third-party plug-ins. If a third-party plug-in directly causes problems, then contact the plug-in manufacturer for support.

VST plug-in handling

Adobe Audition supports the use of VST plug-ins applied throughout the application (Edit View, Multi-track View, Mixer, and Mastering Rack). VST effects are considered a shared system resource (that is, VST plug-ins are usually installed in only one location where all host applications which use VST access them). Because they are shared, changes to VST plug-in files, or their location, can have a undesired affect to other host applications that use VST plug-ins.

VST plug-in files appear in the form of a DLL (Dynamic Link Library) file and are initialized by the host application (for example, Adobe Audition, Steinberg Cubase, Nuendo, etc.) on startup.

When you start Adobe Audition the first time, the VST plug-ins that come with the application are automatically loaded. If Adobe Premiere Pro or Cubase are installed on the same system, then two additional locations will be scanned for VST plug-ins:

-- Program Files\Adobe\Adobe Premiere Pro 2.0\Plug-ins\en_US\VSTPlugins

-- Program Files\Steinberg\vstplugins

Note: To add additional plug-in folders, choose Effects > Add/Remove VST Directory, and then click Add.

You can observe the scanning process in the following ways:

-- When starting Adobe Audition, the splash screen displays the message "Scanning VST effects, VST: [name of VST plug-in file]"

-- In Audition Edit View, choose Effects > Refresh Effects List.

DirectX plug-in handling

Audition supports DirectX plug-ins thoughout the application (Edit View, Multi-track View, Mixer, and Mastering Rack). DirectX plug-ins are also shared system resources, as are VST plug-ins, but they require registration (that is, additional registry entries) from a setup program before a DirectX plugin host application can use them. Because DirectX plug-ins are registred by the system, and not the host application, you should not manually move, copy or delete the DirectX plug-in files. For more information about moving, copying or deleting DirectX plug-ins, see the "Managing DirectX plugins" section of this document.

Note: Some host applications (for example, Steinberg Cubase) are self-registering, meaning that a DirectX plug-in is registered during the application start-up process and does not require a seperate setup program.

Troubleshooting steps

To benefit most from this document, perform the tasks in this section in order. Keep track of the tasks that you perform and the results of each, including errors and other problems. Adobe Technical Support can use this information to better assist you if you need to call.

Note: The procedures in this document are based on the default interface of Windows XP. If the interface is customized, some procedures may vary. For example, a commonly encountered difference is the navigation to Control Panel from the Start menu: You may navigate Start > Settings > Control Panel instead of Start > Control Panel.

1. Restart Adobe Audition and deselect the plug-in from the VST plug-in manager.

Stability issues can arise the first time Adobe Audition scans a new plug-in, or plug-ins from a recently added plug-ins folder, and the plug-in fails to initialize properly. The plug-in design and when it fails in the scanning process can cause Adobe Audition to freeze or halt during startup. When a plug-in fails to initialize, the VST Plug-in Manager is automatically triggered to start the next time you start Adobe Audition. The VST Plug-in Manager lists all the plug-ins that Adobe Audition has scanned and allows you to turn each plug-in on or off. By default, the VST Plug-in Manager turns off all third-party VST plug-ins.

To deselect a plug-in that caused Adobe Audition to freeze during startup:

1. Note the name of the last plug-in that Adobe Audition scanned.

2. Press Ctrl+Alt+Delete.

3. Click Task Manager choose the Processes tab and select Audition.exe in the list of tasks running.

4. Click End Process and click Yes to the task manager warning.

5. Restart Adobe Audition 2.0.

6. When the VST plug-in Manger appears choose Enable All.

7. In the list of plug-in files find the plug-in from step 1 and uncheck the box next to it.

8. Click OK.

Note: If a plug-in fails the first time, then Adobe Audition will not read it again and subsequently will list it as unsupported. You can check choose Effects > Unsupported to view unsupported plug-ins.

For more information about managing VST plug-ins see the "Managing VST plug-ins" section of this document.

For more information about the VST plug-in Manager see document 332575 , "How to use the Audition 2.0 VST plug-in Manager".

2.Re-create the Audition preferences file.

Deleting the preferences will cause Adobe Audition to disable checking for DirectX plug-ins and force reinitialization of VST plug-ins.

To delete the preferences file:

1. Quit Adobe Audition.

2. Navigate to Documents and Settings\[username]\Application Data\Adobe\Audition\2.0.

Important:if you saved your own custom workspaces, copy the UserWorkspaces folder to a new location.

3. Delete the entire contents of the Documents and Settings\[username]\Application Data\Adobe\Audition\2.0 folder.

4. Start Adobe Audition.

3. Run the plug-in in a session with a lower sample rate

Adobe Audition can record, process and playback most hardware supported sample rates (normally up to 196k); however, not all plug-ins were tested or designed for high sample rates. Editing and mixing sessions at high sample rates while incorporating plug-in effects can cause a significant drop in the performance of Adobe Audition or may cause Adobe Audition to crash. If you mix audio in the multitrack or use the mastering rack with files or sessions that are over 48k (48000 samples) and notice problem, then test the plug-in at a lower sample rate.

To check the sample rate capability of the plug-in:

1. In Multitrack Main view, select File > New Session.

2. Choose 48000 in the New Session dialog box.

3. Import an audio file and place it on track 1.

4. Add the effect that you want to test.

5. Play the session.

If the plug-in performs as expected at 48k, then consider finding another plug-in to take its place, or lowering the sample rate of files or sessions.

4. Temporarily disable plug-in automation.

Temporarily disable automation for individual tracks that have effects to test if effects automation is causing the problem. Within the Multitrack view, you can create new automation lanes for any available effect parameter. Not all plug-ins were tested or designed for automation and can cause a significant drop in the performance of Adobe Audition, or may cause Adobe Audition to crash.

To disable plug-in automation:

1. In Multitrack view, locate the track that has effects automation.

2. Change the Track Automation Mode to Off.

3. Play the session.

If the session plays as expected without automation, then consider replacing the plug-in with a similar plug-in, or freeze the track.

For more information about track automation mode see the section "Track Automation Mode options" on page 216 of the Audition 2.0 User Guide.

For more information about freezing tracks see the section "To freeze effects and improve performance" on page 118 of the Audition 2.0 User Guide.

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.

Managing DirectX plug-ins

DirectX plug-ins are registered and have specific path locations written to the registry. For this reason, you should manage DirectX plug-ins using a third-party plug-in manager application. Use one of the plug-in managers listed below to turn off DirectX plug-ins which fail to initialize, or which cause Adobe Audition to freeze at startup. For detailed instructions on how to use the plug-in manager refer to the website listed below and the program's user guide.
