Note symbols effect

I am using note symbols like gruppetto but I don’t hear the effect…
Are they only drawings or we cant activate the midi meaning…?

Only graphic at this time unfortunately.
You will have to insert the grupetto notes, hide them, and add the symbol.

Thank you for answering and I hope cubase take it in consideration next time.

To be realistic, this type of thing is with Expression Maps and specialized VST instruments that support Key Switches, Such a VST instrument would have turns, trills and other articulations that can then be addressed in Cubase.

Something like this will not be included in the Score Editor itself.
