"This module is like a hybrid between the NLC quad logic module and the Sauce of Unce. There are 4 inputs driving chained logic gates (you can choose what logic you want - OR, NOR, AND, NAND, XOR or XNOR by the chip installed). There are 4 gate outputs giving the boolean logic result of the signals on inputs 1&2, 2&3, 3&4 and 4&1. A resistor ladder network gives the stepped output based on what these 4 outputs are doing. From this a S&H circuit with a slew processor gives a smooth output."

"These are nice. The inputs can be any signal crossing 1V. The logic outputs give 5V gates that are all related to each other as made up of different input combinations. The S&H input can be a trigger, gate or CV. The stepped and slewed outputs an be very similar to what comes out of the Sauce of Unce or Buchla 265 SOU. The ICs are all thru-hole, resistors can be 1206 or 0805 smd. Pretty easy build, has 4 LEDs for blinkenlights.Using different logic chips gives you some pretty different behaviour so it is worth having more than one of these. The XOR/XNOR chips cn be used as crude ring modulators at audio frequencies.
This is a great module for just patching in any spare outputs from LFOs, sequencers, ADSRs, etc and generating a whole bunch of gates and CVs that are sync'd with everything else going on in your patch.
