Not sure what you mean here but I think you're opening the SGU file in RB? If so then if the song is using a midi style what you're seeing is correct. What I think you did was save your individual tracks as wav which is ok but that doesn't change the underlying Biab file itself. It's still a SGU using a midi style.

In this case you don't open the Biab file in RB you use the Drag & Drop function to drag your converted wav files into RB. That's a different process from simply opening a Biab file.
