From French developer Mixvibes comes the CrossDJ, a well equipped, reliable and neat designed software. While it's got one of the best beat mapping systems of the available DJ apps on the market, it's got a few too many limitations to be above the entry-level price it's at. What limitations? Well, you can only use a maximum of two decks, and there's a fairly weak collection of effects.
