How to use different instruments for different sections
I'm transcribing a work (Mozart's flute and harp concerto) which has different instuments in different movements. I use section breaks but when I add an instrument (a second viola staff), it affects the whole score, not just the section (movement) in which I am. "Hide empty staves" doesn't work for me, since I don't want to hide anything except the instrument that has no part in the first movement. Is there any solution appart from creating different documents? I'm on MuseScore 2.1. The logical approach would be that each section supported a different instrument set.
