Sibelius can "extract" chords from MIDI file automatically, much the same fashion as BiaB does. This can still be problematic at times, because these things will identify extensions on chords that may not really be there, such as in the case of a straight C Major chord comp where the melody line may cross notes besides the triad.

The MIDI Standard does not contain any chord data. An oversight, I think, that sorely needs corrected but I doubt that will ever happen with MIDI as we know it.
