I'm not sure if this "Fix Sour Notes" 2021 new feature is a real deal, or just another gimmick.

Quote:
"I would not be surpirzed if certain programing features and options look to the Key Signature to make their decision on what will be played."

"BIAB should always have the right key signature where possible."

One way to find out, is to make a new song, set the key to C, then enter C-G-Am-Em for a couple of bars, enter D-A-Bm-F#m for another several bars. Then load a ton of RealTracks to the 16 Utility tracks, from different genres, including soloist and melodist. Single each Utility track and mute the others, play it. If something sounds sour/weird, try the "Fix Sour Notes" feature, see if things are fixed.

I did some test but didn't have much findings. I hope someone can look into this feature, and share some thoughts on whether this "Fix Sour Notes" thing is a life saver, or not.
