I recently got an old Casio CZ-1000 synthesizer, and it's been pretty fun to figure out. One of the first things I came up with was a sort of spacey sound effect
(right-click and save before playing), but more recently, after a lot of tweaking, I made a patch that sounds like the Yamaha CS-80 sound that Vangelis used for the introduction to Blade Runner:http://www.boogatech.com/temp/bladerunner.ogg
(right-click and save before playing)
Everythings in .ogg format, since nothing I use can export sound to MP3.
VLC Media player, which is free and doesn't take up much space, can play the format.
 You will probably need to right-click and save these to your hard drive before attempting to play them. They don't seem to download the way files of the same format do on other servers.
