Something I've recently been doing, is recreating the patches and sounds that Underworld use in their songs. I've not done a lot so far, but...
Bird1 Oscar lead;

Bird1 Oscar lead 2 (Heard in
video);
http://kotera.co.uk/synth/Bird1d.wav
The lead arp from Rez... Quite tricky, unfinished, quiet;

All I've got available online so far... I'm still creating and perfecting these ones at the moment anyway. Still, it's fun. I will admit it's not the best, however...
EDIT:
The site they were uploaded to no longer exists. Links are dead until I get a chance to find the files and upload elsewhere.
