This module is a complex slew and envelope generator.
The concept came from a 1970 paper titled: An electronic simulator for transient processes. The circuit is intended to simulate the electrical properties and responses of biological and synthetic macromolecules in solution when subjected to high voltage pulse signals.
The input signal is sent into two channels where the amplitude and slew can be independently controlled, the slew is voltage controlled. CV1 is normalled to CV2.
The two channels are then summed and difference-rectified (DR) (I have decided that is a verb). The summed and DR outputs are available on the panel and they are also mixed for the main OUT.
The slew rate ranges can be selected by switches to select different capacitors. I decided I like 10nF (high), 100nF (mid) and 1uF (low), but feel free to change these as you wish. Initially I had 100nF, 1uF and 10uF.
The input can be an output from a sequencer or LFO, use gates if you want to module to work as an envelope generator. The input stage has approx. 2x gain so it is best not to turn the Level pots up too high unless your input signal is quite small, otherwise you end up with big square waves.
This module can take some getting used to as it is quite wide ranging and every control affects everything else. Once you get it, you can dial in a huge variety of morphing envelope and slew shapes, even ADSR envelopes, or reversed ADSR envelopes……..RSDA?

These merchants probably sell this module. Huh?
