I need to notate trumpets in C as though they were in Bb as well as clarinets in Bb and horn in F at the proper notation for export to a notation program (Harmony Assistant) for a playing score. Trouble is it won't let me do anything except, mostly, transpose up.
I don't seem to have Bb trumpets in VSL but it seems the orchestra in question uses them and the clarinets don't seem to work either. The horns will let me go down only three semitones although I would probably want to transpose up a 4th.
I think I'm confused since I'm not used to tranposing instruments, being a pianist in another life.
Thanks in advance, Ed
