Splitting MIDI to multiple tracks

Hi everyone,

I'm trying to take a MIDI file produced by Band in a Box and bring it into Sonar. BIAB puts out one single MIDI file though (not sure how the data is separated - channels?), and I want to break up each instrument into it's own MIDI track. The help mentioned something about a CAL file that would do this, but I couldn't figure out how to run a CAL file or where to find a CAL file from the help text.

Thanks for any help you can provide,
