Why do some VST plug-ins not work or display incorrectly?

Audacity will by default display VST effect plug-ins with a full graphical interface where the plug-in supplies this.
VST instruments (VSTi) (such as synths) and real-time VST effects (that change the audio data while it's being written) are not yet supported. These will not load even if you enable or re-enable them in the Manage Effects, Generators and Analyzers dialog. VST 3 plug-ins are not supported.
If any plug-in displays incorrectly, you can use the Manage button ManageEffectMenu.png in the effect's dialog then choose Options... to open the VST Effect Options for that effect. Then remove the checkmark from the "Enable graphical interface" checkbox CheckboxNotChecked.png Enable graphical interface and click OK. When you reopen the effect it will display a simpler tabular interface.
Warning icon
  • On Windows and Mac OS X, Audacity is a 32-bit application so won't see 64-bit versions of VST plug-ins, even on 64-bit operating systems.
  • On GNU/Linux, 32-bit systems will have 32-bit versions of Audacity which won't see 64-bit VST plug-ins. 64-bit systems will have 64-bit versions of Audacity which will see 64-bit VST plug-ins but won't see 32-bit plug-ins.
