Plugin questions

VST plugin installed but not showing in Audacity

Run Effect → Add / Remove Plug-ins → Rescan. If still missing: check the plugin is 64-bit (Audacity 3.x is 64-bit only, 32-bit plugins are not supported). Check the .dll is in a folder Audacity scans — check or add paths in Preferences → Modules.
