Serato DJ 1.7 is now available. Personally, I like Serato DJ's user interface and Pitch-N-Time more than Scratch Live but there is some issues still, hopefully 1.7 will fix most of them - because fixing all of them is not even realistic (lol). SDJ1.7 comes with new features - of course. This release includes a powerful new expansion pack, Serato Flip, as well as a number of important features, bug fixes and optimisations.
