OK, wait, I've got it. I found the part of the BiB manual that deals with Importing MIDI files ... so I can take any MIDI file (including the ones that came with BiB) and essentially force the channels into the tracks with this import tool.
This also seems to be clearing up problems with the drum kits; so there must be some patch changes hard wired into the tracks that I don't understand.
Thanks for all the help from the board ... this gets me going with the software
