Please point me to where I can learn how to use the score editor in Cubase 15 Pro. I am proficient in score in Cubase 12 but it has changed so much! I cannot even change the song titile!
Fellow old score editor user here. I stopped using the new score editor after trying to get used to it for months. It simply does not work for me, too many missing features, questionable workflow, numerous bugs, hardly any improvements over the last two years…
Sorry for the rant, and for not providing any solution to your problem. But in my opinion the new score editor is a waste of time, when you´re used to the workflow and the featureset of the old one.
