As I understand it, Hi-Q MIDI is just the name PGMusic gave to the sound set they created to work with SampleTank to play back your music. It has nothing to do with the notes being played (other than it is one way of playing it). PGMusic actually provided the instrument samples for this (versus something you purchased from IK-Multimedia or some other third party provider that works with SampleTank).

ForteDXi is just another sample player that uses the DXi interface to play back MIDI based on the GM2 standard. Those sounds originated as "giga" format sounds (if I recall, and I even remember that Mac at one time substituted some sounds from his extensive Giga library to use with ForteDXi). As such the sounds generated will be similar, but won't be the same as what you get in SampleTank.

ForteWT is strictly a DXi wrapper for the MIDI sound library that ships with Windows, which doesn't sound very good, but gets you up and running quickly without spending any additional money. Those sounds are completely different from the sounds in ForteDXi, as well as the Hi-Q MIDI sounds played through SampleTank.

Standard BIAB MIDI tracks are generated based on rules established by the StyleMaker and then generated by the Style engine within BIAB. The resulting MIDI data can then be played by whatever MIDI sound choice you wish (Sampletank using their own sounds or the PGMusic Hi-Q MIDI sounds, ForteDXi, ForteWT, Cakewalk TTS-1, your external MIDI module, your external MIDI keyboard, some other third party VSTi library - such as Kontakt or Steinberg's Halion...whatever you choose).

SuperMIDI tracks are actually MIDI phrases recorded in real time by session players, much like RealTracks, and within BIAB are processed by a different engine than standard StyleMaker defined MIDI parts are generated. However, the sound you get from them depends upon the sound source you select. By default, PGMusic has married these SuperMIDI files with their Hi-Q sounds (because then they are balanced properly as recorded and sound consistent), but you are free to choose whatever sound source you wish to use.

I hope that made sense.
