Re-setting the Studio One plug-ins cache manually

Modified on Thu, 07 Sep 2023 at 05:16 PM

macOS and VST2, VST3, and AU formats:

  1. Close Studio One.
  2. Using macOS Finder go to “~/Library/Application Support/PreSonus/Studio One 6/x64/” (without the quotes).
  3. Manually delete the PluginBlacklist.settings file (to delete the blacklist).
  4. Manually delete the PlugInScanner.log file (to force a complete new plug-ins scan).
  5. Re-open Studio One.


Windows and VST2, and VST3 formats:

  1. Close Studio One.
  2. Press Windows key plus R.
  3. Enter “C:\Users\%username%\AppData\Roaming\PreSonus\Studio One 6\x64\” (without the quotes), and click on OK. 
  4. Manually delete the PluginBlacklist.settings file (to delete the blacklist).
  5. Manually delete the PlugInScanner.log file (to force a complete new plug-ins scan).
  6. Re-open Studio One.


After deleting the plug-ins cache files, on the next run, Studio One will re-scan all of your VST2/VST3/AU plug-ins, and depending on the number of VST2/VST3/AU plug-ins installed, the process may take several minutes.
