Thanks to both of you !

I think I'm gonna set up some capture-style configuration, like :
- you click on Tools/Midi capture
- you move your mouse over some widget (a given track's pitch, for ex)
- you move a knob on your hardware controller
- the knob is assigned to the given widget

I think I'll listen for different kind of events, of course 
SND_SEQ_EVENT_CONTROLLER, but also PITCHBEND, NOTEON, NOTEOFF, so that one can 
even change settings with a midi drumset or keyboard.

Do you think it's ok if I listen to midi events in glib's main loop ? For 
example with g_timeout_add() ? Better spawn a thread ?
