This is Infinite Horizon, the new product from Mungo Enterprises, who also invented my favourite thing at Messe. It's an autonomous trance track generator: "The basic concept behind it is that most "classic" dance music is so formulaic it should be easy for a computer to generate. Generating all patterns and sequences from a small set of rules the unit is able to deliver new and original tracks in realtime." Obviously this is easy enough to do in software, but Mungo has actually made a hardware box. (via the excellent new Sendling blog)
