Midi notes on/off

In our theater we use a quite a lot midi notes for triggering the Hog from sound console. I don't know if anyone else has this problem, but it would be nice to have an easy/fast way to enable/disable midi notes.
How you guys are doing it? Is this much a problem for others?
IMO the enable/disable button is a bit buried and it's not easy to make a key macro that enables/disables midi notes and there's no separate button for on and off.
Using an external device or just pulling out the cord always leaves a possibility that you forget to switch things on.
For me the most secure and working solution would be a comment macro that can enable/disable midi notes.
