??? That's odd, why would you want to hear a note that's NOT the
sounding pitch?
That's exactly the problem - you don't hear the souding pitch - for example, if you write a g second line for horn which should sound C, it plays a g as though you had written g for a concert pitch instrument. This is murder to work with if you are using a score for brass instruments.
All the best,
