Most voltages moving around inside a modular synth are very purposeful in their variations: the repeating waveforms of an audio rate or low frequency oscillator; the rising then falling voltages of an envelope generator. However, it can also be useful to have randomly wandering voltages to create everything from subtle variations in pitch to wildly varying volumes or filterings. Noise is an example of an audio-rate random signal.
