This is an idea i got from reading Thorsten Wilms' blog about routing matrices. It's just a mindstorming thing, to get people's feedback.
Anyway, this is a routing matrix for ardour, using parts of the mixer interface. It acts as a replacement for other JACK routing applications.
There could be a global toggle button for mixer/routing, and/or a per-track/bus toggle. Active plugins could become part of the "output" list, but in that case the outputs would function as inserts, indicating so by use of different colors or similar.
To get maximum flexibility, all jack ports would also have to be represented by vertical columns, even though they are not ardour internal tracks or buses.
Anyway, it's just an idea :) I don't even know if something like this even vaguely resembles anything useful. Here's the link to the mockup I made:
Critique (and ideas) are most welcome.
