VST plug-in versions

FabFilter Pro-MB 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.

Both the VST 2 and VST 3 versions of the plug-in automatically adapt themselves to the channel layout of the track they are inserted on (mono/stereo).

For the VST 2 format, there is a separate FabFilter Pro-MB (Mono) version of the plug-in which always runs in mono mode. This is included for backwards compatibility with existing sessions. For new sessions we recommend to use the regular plug-in which automatically adapts itself to the track it is inserted on.
