What is a sgu file? How to open?

The biab sgu file  is a multitrack song.  The “.sgu” is an extension (songname.sgu) associated with Band-in-a-Box.

To open a sgu file you will require the Band-in-a-Box software.
SGUs files are the “source” of the backing tracks.

If you want to change the key of the song, you need the original “sgu” file, created by Band in a Box.
BiaB SGUs will allow you to transpose, delete/add some track etc., with no loss in quality as the midi, but with live recordings.

Where does the sgu file come from.

If you have BiaB and you create your own tracks, get the sgu file by saving the song (saving the song does not mean exporting it, such as mp3/wav, in that case it would not be editable anymore).
If you do not have “Band in a Box”, or you do not have the time or the desire to create your own pieces, you can download privately arranged mp3s, from this site.

If you download these, you will have to use them as they are, if you have the correct sgu file instead, you will be able make any changes you want, as with a midi file, with only limiting the number of RealTracks in your possession.

SGU is the extension of files that contain your relayed song with BiaB. These files are not playable with a music player, but only with the BiaB program.

Auto created songs are saved in a format called “.sgu”, that of band-in-a-box software, which can also be exchanged between musicians, allowing modifications.
The sgu file can be opened by BiaB and modified as you like, key, instruments etc.

However, to play it live, it is not practical to use sgu themselves (search, lyrics, etc.)
To do so, it is more practical a media player.

The difference between SGU, MGU and MGX files

All these name extensions are files openable only with BiaB.
SGU and MGU are files that can contain RealTracks, while MGX are midi files.

Meaning of letters

If the song does not have a melody, it starts with an ‘S’ (eg SGU). If the song has a melody, the extension begins with an ‘M’ (eg MGU, MGX).

Specify better:
S.  The song does not have a melody.
G.  This is a song (G is always present in the BiaB files).
U.  The style is a user style.
M. The song has a melody.
X.  Midi files in a single track

You will not find MGU files on this site, as melody files do not serve the musician who use backing tracks, and they are performed live by the musician, as a vocal or solo instrument.


  • The files are in a compressed format (It is not possible to upload the .sgu file directly to my server for security reasons)
  • If your OS filter blocks the download, read HERE
  • How To Open a RAR file

Many are requesting more .sgu version of the BiaB backing tracks, to be able to modify the key and other parameters.  Uploading a complete and tidy list is hard work. On THIS PAGE, you can have access to all my SGU files.

Technical note (if you have Band in a Box): 


I waiting for your suggestions, comments or questions (English, Italiano, Español, Français).
