NastyVCS

There are not many valueable free multi-effect / channel strips available. Many lack in sound or design, but this plugin belongs to the good.

NastyVCS is an all-round-tool which you can really use even alongside expensive channel strips. It offers many special things like a saturation knob, an AIR-Filter (which really surprised me), boost and cut low-end filter, and many different sounding attack and release modes for the compressor.

Plus it offers a sidechain capability and you can enable/disable individual sections for quick A/B comparison. A much appreciated feature which many pricy competitors are missing.

And this isn't in 32-bit only despite being a bit aged. VOS updated NastyVCS to 64-bit in 2021.

Really worth to at least checking it out, even if you already have fency channel strips in your arsenal.
