Thanks for that. I understand you will have problems narrowing down notes to a specific chord but I wonder if I may I ask you to try this: start a brand new song in composer without any notes and place a chord (from a midi keyboard) using the notes (C F G). My program inserts CminMaj7. There is no context here to interpret this chord other than Csus4. There is no hint of Cminor. I think this is a bug rather than the program choosing a chord from a number of possibilities.
