I just started using this to analyze a specific simple midi track where I plunk out simple chords for my lead sheets. The problem is that if you change any midi after this is done things can get very screwed up. Drums change, the lead sheet gets out of wack, etc. As much as I love the idea of this feature it seems to be causing more of a nightmare for me. Am I missing something? Even in Doug's tutorial on scoring in Logic he complains about this "feature." I feel it to be safer to input the chord names manually via the chord text function the same way one enters in lyrics. I don't think there are weird things that happen when doing it this way. Am I doing something wrong or missing something obvious?
