NoizBox - Schematic
The NOIZ-CORE sub-circuit is taken from Ray Wilson's Music From Outer Space website.
The ENV-GEN uses the 3 spare 40106 gates (2 as a flip flop, 1 as a buffer).
Although there didn't really need to be 2 VCAs I had half of the LM13700 left, so I mixed the filtered and unfiltered signals after the VCAs, making it possible to have an unfiltered output as well as a mixed output.
