Yeah, they code up their own 'instruments' in Max/MSP and some of their music is algorithmically generated.

Of particular note is 'Flutter', a track where no two bars are the same, which was produced in response to the UK Government passing an 'anti-rave' law which attempted to classify dance/electronic music as 'repetitive beat music'. Party organisers were encouraged to have a copy of Flutter, a musicologist and a solicitor on hand in the event of the police trying to enforce these crazy laws. Fun times!
