SGU Acoustic Free Download

SGU Acoustic Free Download (Band-in-a-Box files)

For those who play live acoustic.

These acoustic tracks are not the classic backing tracks, and it makes little sense to be listened to alone, but must be played on them with your instrument (at the end of the page a video example of how to use them).

I suggest you download the sgu files from this page to see the result on your Band in a Box program (just left click on the title). Under the title the audio (.wav) version.

With Band-in-a-Box you will be able make any changes you want.

Technical Note: To get started, mute all tracks except one dedicated to the acoustic guitar. Select a RealTrack (example: "Guitar, Acoustic, Strumming Ev 120", included in most programs)

With Band-in-a-Box you will be able make any changes you want.

Note: Depending on the realtracks you own, there may be differences in settings. Before listening to a .sgu song with BiaB, mute unnecessary tracks. 
By default, all tracks are active, and if you don’t make a selection, you can get an unnatural sound.

Note that these backing tracks are created with the purpose of playing acoustically.  For the classic sgu tracks with full selection of instruments refer to the sgu backing tracks download page

Here is an example of how I use these acoustic backing tracks:

(Full sgu acoustic collection here)


What is a biab sgu file? How to open .sgu files?

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).
