Beethoven 9th 4th movement Instrument change

Hi everybody,
Beethoven changes Clarinets in Bb to Clarinets in A in bar 92.

The manual told me, that I have to define a solo player holding 2 instruments. (that means an additional staff!!).
So far, so good.

Is there a way to change the Cl. key without adding an additional staff?



It doesn’t add an additional staff in the score and part for printing, you only see the additional staff in Galley view.


Here’s the page in the latest manual that explains how instrument changes work in Dorico (from your use of the term “solo player”, it sounds like you’re looking at an older version of the manual – if you’ve got Dorico 4, it’s worth referring to the Dorico 4 manual for the most up-to-date information)
