Entropic Doom

A noisillator: an oscillator for noise. A CMOS logic gate noise generator with coarse and fine tuning feeds a two, three or four pole low pass filter and a passband resonator inside its own loop, with audio and sync inputs mixed into the loop. Bright and dark outputs take the noise before and after the filter, CV inputs set frequency and resonance, and a 1V/octave input plays the noise in tune. An XOR ring modulator and a CMOS gate VCA work on their own, alongside it.
