Disco Noise

Disco Noise is one of my wilder inventions. Simply put I am amplifying the audible noise that I noticed coming from color changing RGB LEDs. It makes some bizarre synth like tones fading in and out like haunted robot screams!
I then run this noise through a CMOS chip to enable pitching it down in increments of octaves.

I found that two different types of RGB LEDs can interact with each other. So I simply took a handful of both and made a combination where you have three individual "voices". Each with their own volume and octave control. To create a totally awful sounding noise choir of screaming robot ghosts!
