Instrument changes (don't works) in parts


Maybe is a very simple thing to do but…
I wrote a score where sometimes I need a double line staff for string instruments. I made this with instrument changes, switching between string and percussion instrument, and the score look fine.
Now I was checking for parts and there, there are no instrument changes and everything is written on a 5 line staff.
I have no idea how to fix this issue.

Here my project
TrioVbr-forum.dorico (1.4 MB)

Thanks in advance

In Layout Options, make sure your part layout is selected in the list on the right-hand side, then go to the Players page, and under Percussion choose the desired presentation type.

It works!

Thank you for the quick reply!
