  • Plug in any musical instrument which has MIDI output (such as a drum set, guitar, or keyboard) and then use that instrument to "play" the drums in Rock Band or Guitar Hero World Tour. Quickly and easily map mulitple MIDI notes to any "drum button".
  • Fast and simple setup. Just press the button you want to program, and then hit the drum pad you want to assign to that button. (You can assign up to 10 notes to any one button).
  • Use the Windows GUI software to quickly view, edit, and save and recall setups. [Screenshot]
  • Use it by itself ("Stand-alone Mode") to play the drums in Rock Band.. There are five push-buttons (Red, Yellow, Blue, Green and Orange) on the top of the box which act just like the drum pads and foot pedal. Great for people with limited mobility, or for places where you don't have room for the full drum set..
  • Connect the external outputs to your own device, or another game controller (such as an Xbox 360 controller).
