Windows, Cubase 15. Personally I find it a bit tedious to use the mouse or keys to input notes in the new score editor - perhaps I need to exercise more. I’d rather stripe the thing together in the key editor, selecting, copy paste between instruments and bars…it is just easier over there. But when - by accident - the ‘dot’
is still enabled in the score editor you’ll get a horrible score and the score notes do not represent what is in the key editor. I have not found an easy way to undo this afterwards
