Hi Aurélien!

This looks great! I have no midi pedal here to make a "real" test, but 
the code looks good. I'm not sure if the gui should stay this way or if 
we should reorganise all midi settings in a complete new window/dialog, 
but it is a pretty good for the moment. I will merge it as soon as the 
next release candidate is released and a new development path (for whats 
becoming 0.9.7) has been created.

Best regards,
