Damn you, Rovastar - you beat me to it
This is a proper preset using the beat detection code found in <a href="http://220.127.116.11/showthread.php?postid=524824#post524824">this thread</a>.
It's a modification of my preset aenema, with a different colour scheme, and obviously the beat detection.
Currently, there are loads of if() statements in the code, so it's not very fast. I'm in the process of cleaning it up.
