An audiotrack is a single channel device which allows you to add a library sample to your track. When you drag an audiotrack device to the desktop, a corresponding audio track is automatically created in the timeline. You can then drag a sample from the sample browser into the audiotrack's corresponding audio track in the timeline. NOTE: It is possible to drag a loop straight from the sample browser to the desktop. An Audiotrack will then be automatically created and the sample added to the timeline.
