VST plug-in versions

FabFilter Pro-R is available in both VST 2 and VST 3 formats. They can be installed and used both at the same time. The VST 3 format offers easy side-chaining, free interface resizing, and is more CPU-friendly in some cases, but it can only be used by hosts that support it, for example recent versions of Cubase, Studio One or FL Studio. The VST 2 format is compatible with a larger variety of hosts.


For the VST 2 format, there are two versions of the FabFilter Pro-R plug-in, a mono and a stereo one:

  • FabFilter Pro-R: Stereo version of the plug-in
  • FabFilter Pro-R (Mono): Mono version of the plug-in

Note: The VST 3 version of the plug-in automatically adapts itself to both mono and stereo tracks.
