I think the Arduino will serve you very well for this. Its US$30
assembled and you can do what you want with it. You could do midi
with it if you really wanted, but I think MIDI mostly gets in the way
these days, unless you are using MIDI hardware like old synths, etc.

Looking at things from a more basic level, you can come up with a
more direct solution... It may sound small in theory, but it in
practice, it can change entire economies. - Amy Smith
