Adding audio busses
From the Insert menu, choose Audio Bus (or click the Insert Bus button in the Mixing Console toolbar) to add a bus to your project.
The number of busses in your project will be determined by several factors, such as the number of outputs that your hardware supports, how you will be using and applying effects throughout your project, or how many audio channels you want to include in a channel mapping for rendering multichannel audio.
By default, all busses are assigned to the Master bus. In this configuration, you can use them for creating subgroups of tracks—for example, you could route all your drum tracks to a bus so you can adjust their levels together without changing their relative levels. However, you can also route busses to hardware outputs so you can use busses for sending tracks to external effects processors or for mixing on an external mixer.

Adding a bus
From the Insert menu, choose Audio Bus to add a bus to your project. A bus channel strip is added to the Mixing Console window.
You can assign up to 26 busses (plus the Master bus), and you can change the number of busses at any time.
TIP If the Mixing Console window is visible, click the Insert Bus button in the Mixing Console toolbar.
Renaming a bus
To rename a bus, double-click the label at the bottom of the channel strip and type a new name in the box (or press F2 to rename the selected bus). The channel strip in the Mixing Console is updated when you press Enter.
TIP Delete all characters in a custom bus name to reset a custom bus name to its default.
Deleting a bus
Right-click a bus channel strip in the Mixing Console window and choose Delete from the shortcut menu, or select a channel strip and press the Delete key.
NOTE When you remove a bus from a project, any tracks assigned to that bus will be reassigned to the previous bus. For example, if you have assigned 4 busses to your project (busses A-D), and later decrease the number of busses by one, the tracks assigned to Bus D will be assigned to Bus C.
