Band-in-a-Box, developed by PG Music, uses sg4 files to save songs created in the application. A file can contain the song's chord progression and associated arrangement settings, allowing Band-in-a-Box to recreate the accompaniment.

Band-in-a-Box is available for Windows and macOS. The sg4 format is an older Band-in-a-Box song format, so support may depend on the software version. It should not be confused with an audio file containing the completed performance.

How to open sg4 file?

Open the sg4 file in Band-in-a-Box on Windows or macOS. Use the program's Open command and select the file.

If a current version does not open the file, an older compatible version of Band-in-a-Box may be required.

How to convert sg4 file?

Band-in-a-Box is the practical way to convert an sg4 file. Open the song in a compatible version and save it in a newer Band-in-a-Box song format, if the version provides that option.

The program can also render or export the song as audio or MIDI, producing a performance file rather than another sg4 file.
