So I attached a photo of a chord track and the track above is the midi that you will see at bars 48 through 56 the notes stay exactly the same on the midi once converting “chords to midi”… but nowhere else on song… just here. The chords are supposed to be a D and B.
There are a couple of ways to end up with midi data that matches the chord track. Can you describe how you did this?
You might check to verify that both the midi notes and the chord event both start at 18.104.22.168. If your midi notes start even 1 tick before the chord event the Dbsus2 would be the active chord at the time and the notes would conform to it and not the Bbmin.
