Make a Rock Band Drum Pedal Pad

Step 5 Make a rack to hold it.

Take one wire hanger, bent the hook down to the bottom and bent the sides under the pads.  Rubber band the hanger in place, and then rubber band the keypad to the hangers.  It is pretty strong and has some give when you hit it with the stick.  Plug the "Y" adapter in and you can use the pedal and the keypad at the same time.
