Here is my situation: I have several patterns. Some benefits from the General Voice Grouping and others don’t (as they were created manually).
The problem is I have to switch on and off “Voice Grouping” every time I change pattern.
The solution would be to apply the Voice Grouping currently selected to a selection of chords with the context menu (i.e right click menu).
It would mean that we do a “destructive” change of our selected chords.
