Cymatics Vortex v1.0.3 [WiN, MacOSX]
This plugin has been used behind the creation of some of our heaviest 808s to date.
It is composed of 4 unique saturation modes, each designed for a different mixing outcome in your low end.
Electric: aggressive, bright sound
Fire: warm, thick sound
Radiation: edgy, rubbery sound
Ultraviolet: extreme, metallic sound
