LANDI TRANCE  Very nice i like this .

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.

JUCK  Very good and professional dj software for daily use. The current version 2.1.4 has many new features that makes mixing easy.

In my opinion it's the best dj software for the mac, if you like BPM-Studio on Windows.

There are many professional looking skins for modern screen resolutions, e.g. a skin for the iMac (1440x900 pixel).

Juck
