The Entropy+Expander packs together some of the most random voltage options in 6hp. It provides a controllable “Glide” (slew) out for the S/T\H, a comparator with a controllable rate (“Thrsh”) of random gates (“Rand Gate”) out with an input to compare other waveforms (Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate “Blue noise” (+3db/octave) and “Violet noise” (+6db/octave) outs.
The unique part of the circuit is a voltage controlled A/B switch thats normalled to the “Rand Gate” out that’s switching between the S/T\H out (left Blue led window)and Infra out (right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the “Entropy Out.” Inserting a cable into “Switch CV In” breaks the random gate normalization and lets you toggle between A/B (left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.
