Mario (and anyone else interested), I have done extensive tests on BIAB Music XML output. A 7alt chord, for example, is exported as a specific alteration of fifth and ninth, rather than the flexible meaning of alt that could have a b5 one time, a #5 the next. I would not be surprised to learn that the OutputCh selects the same chord spellings as Export Music XML.
