The idea is to create a staff and display the Midi information from all the tracks we choose. In that way, for example, we won’t have a staff for every articulation or type of sound and the score editor can be more manageable.
You would only have to route the Midi information to this staff and it would be only for display. If we want to edit the notes on the score you could add a drop menu with the staffs corresponding to each track, where we could edit the midi information, like in a track folder. I think in that way, it would be easier to program this feature.
I believe this could be a big help for all the people that work with big templates.
