Lol ... That had me stumped... I did a LOT of debugging before I found out it was a FEATURE...
I sure appreciate Dr. Gannon jumping in. Now I wonder what would be a good use for transposing a tune, yet leaving the audio in the previous key? I don't doubt that there might be a good reason to do so. I just can't think of one.
I had been checking the transpose setting BEFORE I changed keys, but not AFTER. When I finally looked at the NEW settings, it was a forehead slapper.
But anyway, I'm glad not to be spending Christmas Eve swapping out sound modules, re-installing BIAB etc.
