I get really confused at the difference between staff styles and score sets. If I edit a staff style, particularly relating to space above and space below , it seems to change the parameters equally for all the regions in the track "segment" even though I want it to apply to only one region in one track. For notation sometimes one needs more space below/above depending on the tessitura of the instruments/voices or whether there are text lyrics inserted underneath the notes. Is it possible to have different staff sizes in one full score? I've got a choral setting which needs a large font for the singers but the piano accompaniment doesn't need the same vertical space or notation size as far as the singers are concerned- but it's good for them to see it-- and vice versa for the pianist. She wants the notation big but doesn't need the lyric fonts at the same size as the singers. If you can understand this you're a better man than I am Gunga Din.
