Cubase 15 pro, Score Editor issue

Exporting project to Dorico faced problem: one insttrument (bassoon, Iconica Sketch) lost all notes - only pauses appears in a score. Reopened Cubase 15 project and tried open bassoon in key- and score-editors. Notes appears in key-editor and sounds. And only pauses appear in score-editor. What`s wrong?

It appears that the clef is a percussion clef. What happens if you switch the to correct one?

Thank you for the right note but nothing happend

I would have a look in Score>Layout Settings, Instrument. Maybe the instrument changed spontaneously – was a bug, don’t remember if it was already correctd though

It changed the clef to percussion again spontaneously. It is really bug)

But what can i do in this case to have a full score?

What exact instrument are you trying to set? If Bassoon isn’t working, I would set it to Bass Staff

Tried to do as you suggested: Score>Layout Settings, Instrument. I`ve seen a percussion line in an interface. But it’s Iconica Sketch and Bassoon is not percussion instrument. Why the word “percussion” is present here?

Did you do what I suggested or not? (Change the instrument)

Almost. I tried exectly what you suggested but nothing happened. Then i did this little bit another way - just created another bass track and copied all staff there. All works. Thank you!

I find a cause

10th channel. It is for drums by defolt as i know. I changed it
