Venomode's Complexer plugin isn't just a compressor plugin - it's two compressors in one. Each of these can be independently operated and the two can be used in series or parallel.
In terms of controls, both compressors are identical. You get multiple detection modes, variable knee and visual meters.
Designed to be used for both mixing and mastering, Complexer is available for PC and Mac in VST/AU formats priced at £39. A demo can be downloaded, too. Find out more on the Venomode website.
