I use MuseScore 3.6.0 Portable AppImage, inside computers with Ubuntu Studio 20.04.1 LTS (64 bit Linux flavor).
I just have a technical doubt...
Up to my limited knowdledge, F (Fa) Tube uses transposition because it is a transposed instrument. But, if I select it and write something, the final staff, using or not the "Real Sounds" button, shows me a real sound key staff.
I have to manual change the pitch into de "Staff properties" to get the visual transposed effect, fact that doesn't happen with other transposed instruments.
Is it "normal", I mean "By default"? Or... Is it an small "bug"? ???
