While working with a horizontal fretboard (see previous post regarding legends) I noticed that if I use note names in the legend to the right of the fretboard the notes are all noted as the note name or sharpened note name. Except A# shows as Bb. My preferences are set to U.S. and western style.
Is this just music theory convention that I'm not aware of? (Quite possible I suppose as I am very much a student.)
Kind Regards,
