There's a typically baffling/silly interview with Aphex Twin in this month's Future Music magazine. When asked for a kit list, he says: "Sure. Raveolution 309, the Raven Max, MC-909 limited edition, Quasimidi Van Helden, MAM Freebass 383, Roland DJ-70, E-15, SP-808, Akai S3200, Behringer MX602A and all the Behringer effects that copy other things." When he's asked which software he uses, he says "UPIC by Xenakis puts almost everything else to shame. It's under 1mb and it shits on everyone." UPIC was a '70s experimental French system developed by Greek composer Iannis Xenakis, which is based on drawing on a graphics tablet. It's somehow connected with CCMIX, where they talk about it running on a Windows 98 system. UPIC seems to have developed into Iannix, which you can download from this page. He also talks about liking Ableton Live, but preferring LiveSlice for beat editing/stretching. He uses Etymotic Research headphones. My favourite Aphex Twin track ever is the demo version of Windowlicker, where you can hear that the whole track is put together with samples of him singing.
