Hello Gabriel,
ok, maybe in this case the 5.5.0 update broke something there.
Thanks for the confirmation regarding the score. Good to hear that the combination of Studio One and Notion works well. I am hoping to finally be able to use a single Music Application for everything (so far I am going back and forth between Logic and Dorico ... which is rather inconvenient)., but in this case Studio One won't be the solution either.
Maybe the new Dorico 4 with its enhanced Midi-editing features, will do the trick (as far as there are no audio files involved in the project), because its notation and score playback features are unmatched.
Thanks again and all the best
Kai
