If your VocAlign or RePitch VST3 plug-in is definitely installed, but not displayed in REAPER, you may need to have REAPER rescan the VST plug-ins.
Open the REAPER Preferences panel and make sure the VST3 plug-ins paths includes C:\Program Files\Common Files\VST3
- make sure there are no extra spaces, including next to the semicolons that separate the different paths
Then click the Clear cache/re-scan button.
If these steps do not resolve, please:
- remove plug-ins path C:\Program Files\Common Files\VST3
- click Apply at the bottom of the REAPER Preferences panel
- click OK at the bottom of the REAPER Preferences panel
- Reopen the REAPER Preferences panel
- add plug-ins path C:\Program Files\Common Files\VST3 again
- click the Clear cache/re-scan button.
- click Apply at the bottom of the REAPER Preferences panel
- click OK at the bottom of the REAPER Preferences panel
Please note: If you are using VocAlign Project 5 or VocAlign Ultra on Windows you must use the 64 bit bit version of Reaper.
