'''CGS31''' the '''CGS digital noise''' (ver 1.2) module is a very standard pseudo-random digital noise source with a few enhancements. Instead of running a fixed high frequency clock, a VCO is used instead, allowing for unusual sweeps, and for reducing the speed right down to a series of random pulses. The internal linear VCO can also be bypassed so an external source such as a 1V/Oct. VCO or LFO can be substituted. It has pink and white noise outputs, and two separate (unique) digital outputs for use in triggering other circuits.
Additionally this version has an 8 input DC mixer and a small power distribution board included. The board has been made in such a way as to allow the latter to be cut off, making the board suitable for mounting behind Euro and Frac
While untested, the module should work on +/-12 volts.

* 330R refers to 330
* A 1uF/470k combination may work equally as well as the 0.47uF/1M used to initialize the noise generator.
