Working in A major, I want to put a high (upper) mordant on C-sharp. However, earlier in the bar I have used an accidental to create a D-sharp (in effect, the bar is in E major) and I want the mordant to sound C#-D#-C# to be congruous with the key I'm currently in. However, HA seems to be defaulting to the key signature i.e. I'm getting C#-D natural-C#. I know there's a way to change this, but can't remember or work out how! With thanks David
