I’ve stumbled across a bug with the new Transposition interval for staff notation for fretted instruments.
I setup a new project, and changed the guitar tuning to D-Standard (DGCFAD, i.e., de-tuned a major 2nd). I want this to behave like a B-flat instrument, so I set the Transposition interval for staff notation to B♭2.
The notation now works perfectly, allowing me to switch between concert and transposed pitch. I also want the main chord symbols to reflect the same transposition, so under Layout Options—Players—Fretted Instruments, I checked Use fretted instrument transposition: For notation and main chord symbols.
The problem is that the main chord symbols are transposed by a major 2nd, but the wrong way. In the example I posted below, the notation for both the trumpet and guitar is correctly transposed, but the chord symbol for guitar gets transposed down a major 2nd to Cm instead of up a major 2nd to Em. The trumpet’s chord symbols is correctly transposed to Em.
