DJDANIEL  I am a BPM studio user for a very long time. When I started using MacOSX I always wondered to see if there is an equal software. Once I found UltraMixer I was impressed about the nice looking screens and the easy handling. I am still amazed to see UltraMixer growing and developing further and further. The stability is unbeaten from my point of view compared to other products like VirualDJ or Traktor. The best about UltraMixer is, it is soo easy to use. I don't need a fully fledged Screen, I just need two players and that's it.
