What is an FXB File?

How to Open, Edit, & Convert FXB Files

A file with the FXB file extension is an FX Bank file used with VST-compatible (Virtual Studio Technology) software to store effect presets, often called patches.

The FXB file contains a bank, or group, of presets that can be loaded into a VST plugin.

Single preset files are saved as FXP (FX Preset) files.

How To Open an FXB File

FXB files are plugin-specific, so an FXB file that's made for one plugin will work in that plugin only, and a different one will open in its own plugin.

You should know which plugin the preset is for before deciding how to open it.

Steinberg Cubase is one program that supports FXB files. The software isn't free but there is a 30 day trial you can download for Windows and Mac here. Another program from Steinberg, called HALion, can open FXB files as well.

Note: Since Cubase v4.0, VST Preset files (.VSTPRESET) have replaced the FXB and FXP formats, but you can still open them through the Earlier VST Plug-ins folder. Choose the SoundFrame button and then select FXB/FXP... to load the FXB or FXP file.

Ableton Live, Cantabile Lite, Acoustica Mixcraft, and IrfanView can open FXB files too.

FXB files that don't open with the programs already mentioned may not be FXB files at all. Be sure to double-check that the file extension is in fact FXB and not something similar like EFX, XBM, FOB, or FBX (an Autodesk FBX Interchange file).

Tip: If your file is definitely an FXB file, but none of the applications mentioned above will open it, then it's very likely it's not an FX Bank format file.

Try opening the file in Notepad++ and inspecting the header. You may find some useful information about the format there.

In a sort of opposite problem, you may find that you have more than one program installed that opens FXB files, but the one that's configured to open them by default isn't the one you want to use.

Luckily this is easy to change - see my How To Change File Associations in Windows tutorial for help doing that.

How To Convert an FXB File

Most files can be converted to a new format using a free file converter, but FXB files are an exception. I, at least, have not found a converter tool of any kind that supports these files.

Instead, you can use Steinberg Cubase to convert an FXB file to the newer VSTPRESET format using the Convert Program List to VST Presets option. The new file will be saved in the program's VST 3 Preset folder.

It's likely that the other programs listed above also have some way to save the FXB file to a new format, maybe even something different than .VSTPRESET. Just open the file in that program and, if it's supported, choose whatever Export or Save as option that's hopefully available (usually found in the File menu) to save the FXB file some other file format.
