Set the project playback volume
You can set the basic project playback volume by dragging the Master Volume slider in the control bar. The Master Volume slider controls the master channel strip in the Mixer, and acts as a master volume control for the overall project. This slider not only sets the playback volume of your project, but also affects the overall volume of your mix.
Adjust the project playback volume
Drag the Master Volume slider left or right.
You can also control project volume using the Master track or using the master channel strip in the Mixer.
