In everyday usage, 'chaos' means 'disorder, 'randomness'. In mathematics however, chaos has a very specific meaning. Chaos theory deals with systems exhibiting highly irregular behaviour, seemingly random yet completely deterministic.

Applying this to the world of modular synths opens up a whole new world of modulation opportunities, introducing a natural irregularity to otherwise purely ‘mechanical’ music, yet with much more control and repeatability than just simple randomness.
