I am new to Ardour, but have habits from a different DAW. What I’m used to doing when working on multiple instruments (say a quartet), is to display all parts in the same grid.
This allows me to see instantly the relationships of the instruments: if they are closely grouped or spaced out, if their melodies cross (e.g. the alto goes above the soprano), edit some data as a group (say get all their velocities reduced, at once).
How do I do that in Ardour?
