MIDI editing - displaying the midi content

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?

Thank you

Where did the data come from?

It sounds as if you will have many questions about Ardour MIDI support. It will be more time efficient to get on IRC (Help > Chat from within the program), rather than ask them all on something slow like a web forum.

Thanks for your answers Paul.
Will try the IRC.
