These new versions have more parameters than the previous ones, which means that the parameters used in a project with the former version won't be loaded in the same way for these new versions.
These stereo plugins can work on two channels, left/right or middle/side, possibly in linked mode (only one set of parameters), and can be set up to mix the input signal with the compressed signal (serial/parallel compression). The side chain channels can be used to steer the gain stage (the same setup will be used, right/left or middle/side), depending on the switch on the top right of the plugins. The same coloration stage from ATKColoredCompressor and ATKColoredExpander are used here.
#Musicproduction: Matthieu Brucher updates #free ATKSideChainCompressor and ATKSideChainExpander to 2.0.0
