Wall of Sound Does Not Show up in Logic Pro?

Wall of Sound Does Not Show up in Logic Pro?

After installing Wall of Sound for Logic (in AU format), it may not show up in the list of available plugins. Logic often needs to do a validation.

Here are the different steps provided by Apple to solve the issue.

Restart your Mac

If your Mac is running macOS High Sierra or later and you recently installed a plug-in that isn't available in Logic Pro or MainStage, restart your Mac. Before you restart your Mac, confirm that the plug-in is 64-bit compatible. 32-bit plug-ins aren't compatible with Logic Pro or MainStage.

  1. Choose Apple menu > Restart.
  2. Open Logic Pro or MainStage.
  3. Click an Audio Effect, Instrument, or MIDI Effect slot to see if the plug-in is available in the pop-up menu. If the plug-in still isn't available, rescan the plug-in.

Confirm that the plug-in is installed

If a recently-installed plug-in still isn't available after restarting your Mac, confirm that the plug-in is installed:

  1. Choose Logic Pro X > Preferences > Plug-in Manager, or MainStage 3 > Preferences > Plug-in Manager.
  2. In the Plug-in Manager, locate the plug-in. To filter the list by manufacturer, click the manufacturer's name in the left column. For Wall of Sound, the manufacturer is Two notes Audio Engineering.
  3. If the plug-in doesn't appear in the Plug-In Manager, uninstall the plugin.
    1. Go to Macintosh HD/Library/Audio/Plug-Ins/Components/ and trash the file "Torpedo Wall Of Sound.component"
  4. Launch logic without Wall of Sound instantiated 
  5. Then, reinstall the latest version of Wall of Sound: https://www.two-notes.com/en/downloads-legacy/

Rescan a plug-in

If the recently-installed plug-in is installed, use the Plug-in Manager to rescan the plug-in.

  1. Choose Logic Pro X > Preferences > Plug-In Manager, or MainStage 3 > Preferences > Plug-In Manager.
  2. In the plug-in Manager, locate the Wall of Sound plug-in you want to check. To filter by manufacturer, click Two notes Audio Engineering in the left column.
  3. If "failed validation" appears in the Compatibility column for the plug-in, select the Wall of Sound plug-in in the list, then click Reset & Rescan Selection.

Rescan all plug-ins

  1. To automatically rescan all installed plug-ins, remove the Audio Unit cache file.
  2. In the Finder, press Option and choose Go > Library.
  3. In the Finder window, go to Library/Caches/AudioUnitCache.
  4. Move the files from AudioUnitCache folder to the Desktop.
  5. Restart the computer, then open Logic Pro X or MainStage. All installed Audio Units plug-ins will be rescanned.
