In addition to what John has said, you would want to know what channel onto which BIAB exported MIDI data if you took that MIDI file into another program. You would connect channel 5 to a particular sound, channel 2 to bass etc. to play back the file using the right sounds (called patches). Same thing as John said, to play the song on a software synth it needs to know what channels are what patches.
