SideKick 6 Extended is the most comprehensive sidechain compressor that works in your VST and/or AU compatible host on Mac or Windows. With Side chaining you compress one sound with another. It is most commonly used to duck (bass) sounds on each kick punch. Creating room in your mix for maximum fatness and great dynamics in your tracks.
But it can do so much more... Create sucking ride sounds or a wall of sound when used on a reverb. Check out the demo's on the SK6 product page.
