Tom writes to direct us towards the Erol Alkan forum for the first pictures I've seen of the inside of Daft Punk's pyramid. I'd always assumed they were using two laptops running Ableton and/or Google Mail and/or Linerider, but their setup is wonderfully (and predictably) cool and eccentric: It looks like: 4 x Moog Voyager racks, 2 x Behringer BCR2000 controllers, and possibly 2 x Lemur controllers in the middle (DP endorse the Lemur). Presumably there's also some computers somewhere, but there don't seem to be any keyboards involved at all.
Ps: Daft Punk? 290,000 views and counting...
UPDATE: Seems my alma mater Mixmag have captured a better shot of inside the Daft Punk pyramid, together with some words from Guy & Thomas.
