New version 1.1
Old version 1.0
Release Notes New parameters: Auto-Gain and Output. Output allows you to reduce/boost the volume at the output of the plugin. This is great if you want to increase saturation without increasing volume. Auto-Gain automatically adjusts the output gain relative to the saturation so will keep the output volume at a more consistent volume.
