I have read elsewhere that the random mod is a S&H circuit. (my aoplogies for bringing up a synth other than the Poly 800, both my polys get used a lot even with a moog and a DX in the studio). "Pseudo-random". The Moog MG-1 used a single-chip pseudo-random noise generator, the MM5837. Since its output *does* repeat, then sampling at a low rate would give you a fairly long cyclic pattern. There are a couple of sites out there with replacements for this chip based on cheap off-the-shelf microcontrollers. Gordon MM0YEQ
