Rock Band. More Awesome.

3 sticks is easy to figure out:
Right hand- 1 stick on yellow or blue
Left hand- 2 sticks, on yellow/red or blue/red.

Then all it takes is a simple roll with your foot hitting every time you use your right hand. Granted, it's still extremely difficult because you're basically doing a 125bpm roll for the entire song, but it's a simple concept.
