Reaper - my plug-ins aren't showing up


PROCESS.AUDIO plug-ins are compatible with Reaper 5 in 64-bit mode ONLY.

1. PROCESS.AUDIO plug-ins are 64-bit only. Our plug-ins will work in either VST2, VST3, AU formats as long as Reaper is installed in 64-bit mode.

2. Make sure your plug-ins are installed in the correct and default locations:


  • /Library/Audio/Plug-Ins/Components/  (AU)
  • /Library/Audio/Plug-Ins/VST/  (VST2)
  • /Library/Audio/Plug-Ins/VST3/  (VST3)



  • C:\Program Files\Vstplugins  (VST2)
  • C:\Program Files\Common Files\VST3  (VST3)


3. Try opening up Reaper and going to the Options menu and selecting Preferences at the bottom.

4. In the Plug-ins section on the left bar, select ‘VST’.

5. Make sure both VST2 and VST3 paths are listed in your VST Plug-in paths. Try clicking ‘Clear cache/re-scan’ and ‘Rescan,’ and then check to see if your PROCESS.AUDIO plug-ins show up. You might also want to re-start Reaper.

6. Click the ‘Clear cache/re-scan’ and ‘Rescan’ buttons again. (You might want to try this multiple times)
