Notes about the MGU file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The MGU file type is primarily associated with 'Band-in-a-Box' by PG Music, Inc.. Band-in-a-Box is a music generation application. Just type in the chords to any song (like C or Fm7b5), choose a musical style from the hundreds available, and click the [Play] button. Band-in-a-Box automatically generates a full backing arrangement including RealDrums and RealTracks.
