Mac, you're correct that in BIAB the current system works. I was only targeting the printed (final) output to sheet music being displayed as NC. That seems to be what started this thread to begin with - what printed music generated in BIAB looked like. I don't need (or want) to see NC in the chords window of BIAB. That would be redundant.
Thanks and have fun with BIAB. I certainly have a lot more fun thanks to Mac and a lot of others that explain things when I get stuck.
