Virtual DJ Free has some limitations compared to its paid edition, but it remains a viable option when you want to play the DJ back at home. The idea is that you won’t be able to use any DJ related hardware, such as mixers, controllers, etc.
Being software only offers pitch control, many decks, mixers, gain controllers, and equalizers.
More advanced users may take advantage of master tempo, beat-match features, smart loops, and different additional plug-ins, especially useful when one needs a special sound effect. Video and karaoke are also available in the free version.
