You can add arrangement markers to a project to create different sections, such as an intro, verse, and chorus, and then move the sections in the Tracks area to quickly rearrange the project. Arrangement markers can be particularly useful when you have added some material (recordings, loops, or media files) to the project and want to try out different arrangements.
By default, arrangement markers are eight bars long. The first arrangement marker begins at the start of the project. Each additional arrangement marker you add starts at the end of the previous one, with no space between. Arrangement markers are most useful if you add them to every section of the project, so that you can rearrange the entire project.
You add and edit arrangement markers in the arrangement track, which appears at the top of the Tracks area. When you add an arrangement marker, it is eight bars long. You can resize it to cover the section of the project you want it to include, and rename it to reflect its place in the project.
Note: If you add arrangement markers to a project, then add a Drummer track, Drummer regions for each arrangement marker are added, with the length and name of the regions corresponding to the markers.
