The sequencer is where the majority of time will be spent and where most of the functionality that the user sees resides. The main areas and functions of the Sequence tab are as follows:

### Reordering Rows

Models and timing tracks can be reordered directly in the sequencer by dragging their row in the row header (the names column on the left) up or down to the position you want.

### Song Structure Regions

Song Structure Regions let you divide the timeline into named, coloured sections - such as Intro, Verse, Chorus and Bridge - so you can see the structure of the song at a glance. Regions can be created from an existing timing track's marks.

Each region supports bulk actions that operate on everything inside it, including copying and filling effects across the region and applying a colour palette. You can also export one or more regions as new, self-contained sequences, which is useful for reusing a chorus or other repeated section.
