Hi, Jonel -

SGU is what PGMusic calls a song file. It is a BIAB file that does not have a melody or soloist track in it. Once you add either a melody and/or a soloist track, the "S" in SGU becomes the "M" in MGU.

The "U" stands for "User". When BIAB first came, there were only a handful of styles (they are the MIDI styles that begin with ZZ (like ZZJazz). These were numbered, and so initially instead of SGU (which came along later), the file extension indicated which ZZ style was being used. So, for example, a song file using the ZZJazz style would have an extension of SG1 (since ZZJazz was style #1). Once there were more than 10 styles, they started using letters, so you will see extensions of SGA or SGB. If you add a melody and/or solo to the song, the next time you save it, it will start with "M" instead of "S". So your ZZJazz SG1 song would become an MG1 song.

Later, they replaced the numbers and letters with the letter "U" (for user). In fact you can save all your SG-whatever songs as an SGU file and it still plays fine.

When BIAB allowed you to bring a multi-channel MIDI onto the melody track, you will see those files saved as an MGX file.

Here is a table of the original 24 built in styles:

As I recall, I believe there is also a file utility that allows for bulk rename of the legacy file names to SGU/MGU.

Clear as mud?
