.FXB File Extension

Virtual Studio Technology is an audio plug-in interface that allows Digital Audio Workstations to install additional audio effects. While the VST interface was developed by Steinberg, many DAWs, including Steinberg Cubase, Ableton Live, Image-Line FL Studio, and LMMS, use the VST interface to allow users to install plug-ins.

In the past, VST plug-ins loaded effects from FXB files. These files contained some combination of new instruments, audio effects, or MIDI effects. While many DAWs used FXB files, each FXB file was linked to a specific plug-in. So, the FXB file could be loaded only from within that plug-in.

With the release of VST 3, Steinberg replaced FXB and FXP files with .VSTPRESET files. However, some DAWs still allow users to load FXB files in their associated plug-ins.

Steinberg Cubase, Ableton Live, Image-Line FL Studio, and LMMS all allow audio editors to import FXB files. Keep in mind, however, that you must also install the plug-in an FXB file is associated with to use the FXB file.

To import an FXB file in Steinberg Cubase:

1. Select and load the plug-in your FXB file is associated with from the Earlier VST Plug-ins folder. Then, click the SoundFrame button.
2. The Preset Management menu appears. Select Import FXB/FXP....
3. Locate your FXB file and click Open.

How do I convert an FXB file to a VSTPRESET file?

If you want to convert a plug-in's FXB files to VSTPRESET files, you can do in Steinberg Cubase by:

1. Opening the Preset Management menu.
2. Selecting Convert Program List To VST Presets.

The converted files will then be stored in the VST 3 Preset folder.
