Super crazy powerful quad function generator with randomness, random outs and ins/retriggering via expansion, cv over everything and lots of other stuff. Kind of like having a dual Make Noise Maths with additional voltages and random options. Bipolar slew, attenuverters, looping/LFO modes, various shape and speed triggering options. All in only 22 HP! This thing is insane. Got it as part of an early backer campaign a few months back, and I've never seen one/the pair for sale used. The only way currently is to buy from ADDAC and import from Portugal. Really versatile, I just have too much stuff and am consolidating. In great condition aside from a small amount of rack rash.
