I was also kind of curious if Wayne Horvitz digged out all those old samples or he did something new? Did he really have them lying around fro ten years? They are pretty important in the Naked City sound, especially Torture Garden stuff.
granted, it was quite a while ago, but i spoke with wayne about his sounds at a zony mash show. he's got such a distinctive bag of tricks. anyway, he told me he spent hours and hours in the 80's programming his own sounds on (i think) a DX7. he didn't want to ditch all that work when he switched keyboards (after all, it's 'his' sound), so he's got all the sounds loaded into some box, which then patches in to his nord keyboard. he also uses some effects pedals.
so, my guess is he's still got them around.
Wayne is IMHO, the undisputed master of the DX-7, one of the most difficult to program keyboards ever made, at least without a computer editor. He currently uses a Yamaha TX-7, which is a little table-top box of the same vintage as the DX, it's essentially a DX without the keyboard.
