3D Model

This 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 module includes an 8 input DC mixer.
