The Channel Strip plug-in window is organized in several sections: Input, FX Chain, Output, Dynamics, and EQ/Filters. The Dynamics and EQ/Filters sections can be independently shown or hidden. This lets you access controls or free up screen space, depending on your needs.
When showing the Dynamics or EQ/Filters sections, several tabbed panes of controls are available for each section. You can click a tab to show the controls for that tabbed pane. For Expand/Gate and Compressor/Limiter, and also for the For the EQ and Filter effects, clicking the corresponding control point on the graph display automatically shows the tab for Expander/Gate or the Compressor/Limiter, or the corresponding EQ band or Filter.
