J1000 has released MCS6, a freeware multiband compressor and saturator in VST plugin format for 32-bit digital audio workstations on Windows.
MCS6 is an advanced mixing and mastering tool designed for experienced users who are looking to apply precise compression and saturation adjustments to the processed audio signal.
The plugin is capable of degrading the sound quite easily when not used as intended. It is a highly capable and efficient mastering utility in the right hands, though.

Unlike most multiband compressors on the market, MCS6 is based on a serial structure, meaning that each processing stage will affect the signal reaching the next one. Speaking of processing, the six stages feature adjustable frequency range, compression, and saturation controls, along with the stereo width and output gain parameters.
The developer recommends going through the provided presets first in order to understand the plugin’s features and its unique signal flow.
A detailed user manual in PDF format is also included in the download, explaining all of the control parameters and listing various usage tips. Most importantly, it is recommended to adjust the parameters from top to bottom of the user interface (starting with the filter section) while carefully listening to the processed signal on the output.
Keep in mind that less is always more when it comes to powerful multiband processors such as the MCS6.
Unfortunately, MCS6 is only compatible with 32-bit VST plugin hosts on Windows. If you’re using a 64-bit digital audio workstation, you can still put MCS6 to good use with a third-party utility like jBridge or 32 Lives. Mac users are out of luck in this case, though.
The plugin can be downloaded directly from the product page linked below, with no registration required.
UPDATE: The plugin is no longer available and the developer has removed it from their website.
MCS6 is available for free download via J1000 (2.19 MB download size, RAR archive, 32-bit VST plugin format for Windows).
