I have 4 midi tracks meant to be soprano alto tenor bass; I'd like to get these into the score on a grand staff with soprano/alto in the treble clef - soprano stems up, alto stems down; same thing in bass clef: bass stems down etc;
also, when I'm viewing my current four staffs in treble clef and change one to bass clef, they ALL change to bass clef;
