A
Loop is a small section of a media file that repeats continually. VirtualDJ provides a complete set of looping tools to quickly and easily select, execute, save and record
Loops .
In the
Starter Layout the
Loop panel offers just the basics. The size of the
Loop is displayed (number of beats) in the center and when clicked on, engages/disengages an automatic
Loop . Clicking on the arrows to either side of the
Loop button will decrease the
Loop by half or increase it by double it's size.
