In your picture with the C#, assuming it's enharmonically a Db then it's a flat five on the G7 chord. I could see that being a perfectly normal enhancement for a real artist to play. Elsewhere in your many threads it was mentioned that you cannot control voicings, but you can usually 'fix' such things by several methods including editing and partial regeneration. I will just add that an artist might simply have thought the 7flat five sounded good here. QUESTION: Did you have a melody note in the song file? If for example the melody was Cnatural or D, then I think BIAB would have avoided that C#.

I don't think you have commented that you read the article I wrote on the subject of 'wrong' chords, in the Tips and Tricks forum. What did you think of that? Anything to add or change?
