Whenever I make changes in the left or right pane (Layers) during playback of a melody in Dorico I immediately hear the change in the playback sound. But when I change something in the middle panel (turning on/off vibrato and changing the levels) there is no change at all in the produced sound, no vibrato at all is added.
Same for legato btw, whatever changes I’m doing I don’t hear the slightest change.
