Help with Arduino as USB MIDI

Hello!!!

I have a question on how to use the Arduino UNO as a USB MIDI keyboard. My idea is to program the Arduino to play a song as a MIDI keyboard with USB on iPad GarageBand. I have seen the tutorial http://arduino.cc/en/Tutorial/Midi put that was with an MIDI plug. Pleas help!!!

Thanks!!!!
