I had a couple of those TC midi pedals (the TC G-Minor). They are very awkward to use, especially if you might use them for tap tempo. The way the pedal is designed, it rocks to three positions. That is, you're not actually pressing a button with your foot, but rocking the top of the pedal to press a button under the pedal. This is very had to explain. But if you look at a picture of the pedal, you might understand what I am trying to say. I frequently had trouble hitting the pedal in just the right spot to engage the switch.
