Sorry, I should have checked Ardour. But anyway I see that you really now what 
you're talking about, since you've already implemented it using MVC. On the 
other side Peter Brinkmann seems to be your opponent of choice in regard to this 
topic, since he made Midikinesis (and presented it at LAC) :

As I said in my previous mail, one of the great argument in favor of 
midi-enabled widgets is that it allows to use h/w controller with both audio and 
non-audio applications. But this is getting slightly out of topic.

Thanks for discussing my ideas and for your constructive criticism.
