The timeline arranger is the main area where the song is composed. It consists of a collection of events, such as regions, positioned against time. Some events (such as regions) will open separate windows for further editing when clicked.
The timeline arranger is split into a top arranger that remains fixed on top and a bottom arranger below it. This way you can pin tracks you want to always be visible at the top.
The following arranger objects can exist inside the timeline.

The following operations apply to regions.
Regions can also be looped inside the timeline, by moving the cursor to the bottom-left or bottom-right edge of the region, then clicking and dragging.
If the region is already repeated, it cannot be resized anymore until its loop points match exactly the region's start and end points.
Regions can be renamed by selecting them and pressing F2.
Audio regions can have fades. Fades are gradual increases or decreases in the level of the audio signal, and their positions can be adjusted by clicking and dragging the top left/right corners of the region.
Clicking and dragging the grey part up or down will adjust the curviness of the fade.
The type of fade algorithm used can also be changed by right-clicking on the fade and selecting.
The various types of fade algorithms available are illustrated below.
All audio regions have some additional, built-in fade in and fade out that cannot be disabled. This is used to avoid clipping and should be unnoticable.
