They also made frequent use of the sounds of a signal generator.

Well-known examples of its use are on The Who track " Won't Get Fooled Again " ( as an external sound processor, in this case with Pete Townshend running the signal of a Lowrey Organ through the VCS3's filter and low frequency oscillators ) on Who's Next and Pink Floyd's " On the Run " from The Dark Side of the Moon, ( which made use of its oscillators and noise generator, as well as the sequencer ).

A pseudorandom number generator is a deterministic algorithm, although its evolution is deliberately made hard to predict ; a hardware random number generator, however, may be non-deterministic.
