"This is a heavily modified and circuit bent Alesis HR 16. The basic idea is that you can change the eproms and then mangle the sounds into oblivion by way of the knobs and switches which create all sorts of unpredictable and fairly brutal noises. The result can be anything from utter industrial magic to unusable garbage. Comes with a number of eproms incl. Korg, Linn DMX, Roland The machine is very unstable. Sometimes it works sometimes it just doesn’t. I have no idea how to make it more stable and when it comes on and produces sound, it’s absolutely random and unpredictable. The best way to think about this is as a sample source in that you have a tape running all the time and then pick and choose the best noises that come out of it. The great thing is that you would never ever come up with these sounds if you were to program them in a targeted and controlled manner. But on the other hand, it’s of course frustrating when it doesn’t come on at all. The starting bid is set accordingly. The buyer may wish to have a technician take a look at it."
