I have searched the forum and found several topics about editing rests, but following the various steps suggested doesn’t seem to work for me at all. I then saw mention that perhaps things are different for untuned percussion parts, which may explain my problem.
In the attached screenshot,
in beat one, I want to replace the eighth note rest and sixteenth note rest with one dotted eighth note rest. Not only is it more elegant, it is the standard notation (this is a very “classic” 12/8 drum part). Indeed I entered the rest that way, with force duration on, in note input mode, and Dorico placed the cursor at the right place for the sixteenth note, but then once I entered that sixteenth note it automatically inserted those two rests.
Thanks in advance.
