How to build a MIDI Rotator -Anyone

Is the code working just like in the video with Mr Kilgore ? ( with 4 additonal notes, Velocity scaling, Display, 1 pot, 3 buttons, Save option, etc etc) ?

Obviously the most complex thing about this project is the coding, but if this ( http://ruggedcircuits.com/AD130/Rotator.pde) is the complete code would it be possible for a noob like me to put it together ?

All help will be greatly appreciated.

Thanks !
