Serato DJ has a brand new look and a greatly improved software layout, optimized for simplicity and a great experience. The new interface also offers two and four deck view modes for four deck controllers, alongside improvements to the cue point and looping controls, which now allow you to display either 8 cues, 8 loops or a combination of both depending on how you perform.
