[PD] Simple midi controller for installation

[David Merrill]

.. that sounds like advice-from-experience!

Marius has a good point there. I would add to it that you should also make
sure that you don't leave a window foregrounded that will make a "status
beep" or any other unwanted sound when the particular keys that you've
chosen are pressed. At our recent SIGGRAPH installation we had a few minutes
where we heard the apple "bonk" noise every time someone would press one of
the buttons, and realized that the system control panel was the foregrounded
application, so it was receiving the button-presses also.

modifier keys work well for this (control, shift, etc) - but if you need
12-16 buttons, you'll probably want to just use letters.
