I get these kind of requests all the time. "Peter, thanks for the
helpful coverage on the USB MIDI controllers, but when will someone finally release audio hardware I can really use, like a concrete block that plays algorithmic music for 30 years?"
Yes, folks: it's a piece of concrete.
With a DSP chip inside. That can randomly generate algorithmic music
for 30 years (after which, it dies . . . unless it's robot soul goes
insane thinking about its own mortality, a la Blade Runner). Good news
for DIY types, though: the Boston-based DSP collective that created
this is working on a new cheap DSP box anyone can use. Encase it
concrete if you like, or (more useful) use it in your own installation
or performance rig. More on that soon. [Thanks, eyebeam]
