Stagecraft Software included RingMod plugin in our April 2016 goody bag.
The RingMod is the dirty little secret of synth enthusiasts and dark hip-hop and dub producers everywhere, but it is little understood, and often overlooked. The Ring Mod has been used in the design on many, many synthesizers, particularly the early modular synths (Moogs, Oberheims, etc). Notably, it was also used as the voice of the Daleks (in Dr Who). More recently, Ring Modulators have been used to make distinctive dub-bass wobbles, and some of the weirder noises you here in the music of Amon Tobin, for instance.
