Capoing a Pedal Steel Guitar ... down!

While I was visiting Steve, he asked about capoing. I'm embarrassed I hadn't implemented it before seeing him. It turned out, of course, to be rather simple to add that functionality. So, I sent him this video. Excuse my misspeaking, I say "minor third" at one point when I meant to say "major third."
Also note that this is the Proof of Concept instrument, where pitch-shifting was done by means of Puredata on my laptop.
