Defining or altering instrument names / settings
I am writing music for Alphorn. There is the choice of "Alphorn" in the list of instruments, but it is written in the bass clef. Usually Alphorn music is written in the trebel clef (analogous to the horn). Furthermore there are different tonalities for alphorns as well, e.g. in F (again like the horn) or in G minor.
I wonder if and how I can create an instrument or alter the settings.
