As I understand it, MIDI Super Tracks are MIDI, but are processed much like a RealTrack is processed. They use a different engine than the MIDI processed within a traditional MIDI style. Like a RealTrack, you select the MST individually, although they can be included as part of a style. BIAB recognizes the track as MIDI Super Track and handles it accordingly.

For playback, you can choose whatever MIDI device you with, to include Hi-Q patches, a general MIDI source, a VSTi or DXi, etc. You can even assign a different instrument than what was intended.

My understanding is that MIDI Super Tracks fill the need for performance style where it doesn't matter so much the instrument used (for example, a piano, for which there are excellent synths to make a piano sound). That's why you don't find guitar MST's, because they will pretty much always sound like a synth, rather than a real guitar.
