Noise Source
White noise output jacks - Two identical outputs for white noise. White noise is a random signal in which all frequencies across the frequency spectrum are represented equally, and is useful for wind and surf effects.
Pink noise output jacks - Pink noise is a random signal in which each octave across the frequency spectrum is represented equally. It tends to sound darker and bassier, and often works better as a mod source if you don't want total chaos.
Pink Lady was a short-lived Japanese novelty vocal duo from 70s. They briefly had their own NBC variety show, back when that corny crap was the business (kinda literally). It later was changed to Pink Lady and Jeff, but we don't talk about him, ok?
