"MIDI action" menus are always empty and can't be interacted with
I'm a non-keyboard player trying to write for piano, I have to be able to hear my score correctly since I cannot play it myself. So, I would really like it if corone and similar marks could have functional playback.
They don't, but I could make them do that myself, I've been doing it for years on Finale. But here, when I right click an articulation and go into "Articulation properties" I am greeted by an uneditable "channel" field that says just "normal", and an uneditable "MIDI action" field that doesn't contain anything.
So, how do I change that?
