FirComp Low Ratio "quick addition" version

This is a "quick addition" version of FirComp while v2.0 is under development. This version breaks compatibility with current projects and needs to be rescanned to work correctly. It adds additional compression ratios of 1.2 and 1.5, and an additional 100Hz sidechain hipass filter option.


Installation simply involves downloading and unzipping the correct file, then copying the plugin file/bundle into the correct folder/directory for your system. Depending on your DAW or host software, you may then need to "rescan" your plugin folder. The folders/directories suggested below are the defaults for most systems, but you may have a different preferred location.
