When I built my P600 clone I wanted to include white and pink noise sources, but only on one control with a center zero. This is my attempt using an Electric Druid Noise 2 chip and an AS3360 dual VCA to sweep between white through zero to pink. It works on a 0-2v CV with 1v being center off.
I implemented it on the P600 (although the firmware needs modding to use it properly) and also on the MSx variation that I posted previously.
