I said it may not suit your needs. I run them on 2 seperate laptops, and the beatlock is my ears. When I used to play on 4 CD players, I had to really on my ears and skills to match multiple tracks and still do. I didn't let the software match everything for me. I am just saying, different people like different tools. I am glad you love Traktor, Some people love Serato, and I have never seen a 4 deck serato running on one machine, but I also never hear anyone say it wasn't pro caliber software. I wish you luck getting everything set up to suit your needs.
