I am very much a computer programming dummy. Windows programs were invented for me lol. When you say mapping, I have no idea what you are talking about. As far as using it as a mixer, I already have a good mixer that I use, so it would not do me any justice to run it that way. The item is less than 2 years old. I got it at a Best Buy that was going out of business. I used MIXXX on a few linux computers that my friend built for me, so I was familiar with the way it works and when I saw the reviews on the SCS.4DJ I noticed that it is indeed identical in the way it operates, so I had no problem spending the money for it. I guess I will just get the laptop that my wife and I were looking at and download MIXXX to it and buy a splitter so I can cue tracks and just use the wireless mouse to operate the program. The SCS.4DJ will then become a backup device.
