hmmm.

well if someone can make a case for the value of reading the binaries
i'll pay postage and send them out. i don't have spare 707 chips
though, so maybe someone else wants to send those. burning new sounds
seems like a cool idea if it's possible, but i'm kind of more
interested in chopping up my 909 at the moment. my 70727 (
http://userwww.sfsu.edu/%7Egzifcak/tr-707.html ) is pretty much a
finished piece unless something drastically cool pops up.

anyone
