Personally I would not put any pitched percussion instrument on a percussion staff line. However can't you simply edit the staff name to what you want?

yes of course, but the sounds are linked to "change instrument"

You asked about the staff name. Now are you asking a different question?

staff name and staff instrumental sound are linked by Change instrument utility... especially in the first bar

When you changed instrument to chimes or bells, afterwards when you want to go back to drum percussion you need to change instrument again. It will playback correctly after that.

dear Ernest the first bar Chimes are inserted with Change Instrument Utility?

I understand simply use the same change instrument to change it back to percussion. When you no longer need chimes.

BTW, Alessandro is a great name. I like it very much.

… if one has (typical of percussion...) to use an instrument which is not the main staff instrument in the very first bar?

just to be clear: staff name Percussion, but if first bar starts with …

If I understand you correctly, you need the staff’s Full Name to be Percussion, but you are using the Change Instrument utility to change to another instrument in the first measures - right?

And the Change Instrument utility also changes the staff’s Full Name - right?

What works for me:

Window menu > ScoreManager > Instrument List

Click on the button {Full Name…}, and change the Full Name back to Percussion.

The playback will not change to Percussion when you change the Full Name.

thanks Peter, perfect...

but in my experience it changes back to Tubular belles (or whatever..) in the following system;

anyway good!

… in my experience it changes back to Tubular belles (or whatever..) in the following system …

This is a misunderstanding.

The so called [Full Name} is [the staff name in the first system}.

You can enter a shorter name (or whatever) as [Full Name}.

The so called {Abbr. Name} is {the staff name in system 2 and all the following systems}.

You can enter a complete, un-abbreviated name (or whatever) as {Abbr. Name}.

In Other Words:

To change the staff name in the systems {2 and onwards}, change the Abbr. Name.

You can change the Abbr. Name to Percussion or whatever - the playback will not be affected.

brilliant!
