Highly Liquid make expensive, professional-looking circuit bent gear, like this endlessly entertaining Casio SK1 Keytar, and midi kits for the Speak & Spell. Their new thing is the Glitchdesk system. The $249 Bend Workstation is a big banana jack patchbay. You (or more likely Mr Highly Liquid) take your TR-505, or Speak & Math or whatever and run all the contact points out to an RS232 socket. You can plug that into the back of your Glitchdesk, and get instant MIDI control over the bends. It seems like a cool idea and a reasonable price, given the amount of development work that must have gone into it. But the hardcore benders [!] on Get Lofi seem to really hate the idea, because circuit bending is supposed to be all about art and DIY and the real fun is soldering in your own bits and pieces.
