I use traktor it came with the mixtrack. I had to buy the traktor pro
software in order to record audio and have all the sound effects. If you
buy the numark mixtrack pro it comes with virtual dj which I suggest. The
pro comes with the built in headphone and audio jack which is important to
have or else you have to buy an external sound card that costs the same
difference as the normal and pro versions. But yea it is fun I bought it a
little while ago have been messing around thanks if
