Plugin problems
Installed a plugin but cannot find it?
An installed plugin may still be missing from your music app. The app may not support its format, your computer may not support that version, or the app may be searching the wrong folder. Check these before moving or deleting files.
What is a plugin?
A plugin adds instrument sounds or effects to music software. Some products also include an app that opens on its own. That app can work even if the plugin has not been installed.
Check four things
- Format: is it VST2, VST3 or AU, and does your music app support it?
- Compatibility: does it support your operating system, music app version and processor?
- Location: is your music app searching the folder where the plugin was installed?
- Scan: enable the plugin format in your app’s settings, then let the search finish. Follow the app’s manual.
Which folder on Windows?
Steinberg lists C:\Program Files\Common Files\VST3 as the standard 64-bit VST3 folder. VST2 may use a different location. Keep the formats separate, and avoid moving files by guesswork: one plugin may need several installed files to work.
What else matters on Mac?
Check that the plugin supports your Mac’s processor. Intel and Apple Silicon versions may have different requirements. Follow the manufacturer’s compatibility details for the version you installed.
What to send if it is still missing
- Plugin name, version and official download source.
- Music software version, operating system and processor.
- A screenshot of plugin source settings and any error message.
