Temporary Instrument Swap
I haven't had MuseScore for too long, but for some reason, I've caught on well, but I have been having this problem for a while now and I decided to take it to MuseScore.com for help.
You see, I have a certain 7-and-a-half-minute long song with a sad part in the middle. That sad part has a trumpet solo. I felt like the solo needed something, so I played around with the instrumentation for a bit and I realized that the solo would sound best as a flugelhorn solo. Problem solved, right? No. Now I have this extra staff that has 45 seconds of playtime.
With that said, the question is: How can I temporarily change one instrument into another without adding/subtracting staffs, all mid-song? I know it might be complicated to code, but this is something I feel should be an option.
