My teacher has one of these pedals. It was made in Italy and went with some keyboard he's long since gotten rid of.

I took it apart and there are two contact strips: one for the downstroke and one for the upstroke. So I guess it sends a note message for pedal down, and one for pedal up. It only has a 1/4" tip/sleeve jack so I'm not sure how it's sending that to the keyboard.

Since playing around with the Steinway Gigasample, I keep thinking it'd be nice if the pedal could be more expressive and get those "in between" spots or just not CLANG if I life the pedal gently.
