+The main window is called the \textit{Program} window and is often just referred to as the \textit{timeline} \index{timeline}. Here is where you enter the main menu operations.
This timeline consists of a vertical stack of tracks with time represented horizontally on the track.
It is the output of the rendering operations and this is what is saved when you run the \textit{File} pulldown, Save command.
Immediately to the left of the timeline is the patchbay \index{patchbay}. The patchbay contains options that affect each track.
