Free version/Pro version 
UltraMixer is a DJ software that allows one to mix tracks with real ease. Though this software has a host of features, this disappoints. The first disappointment comes in the form of the graphical interface. When almost all DJ softwares come with a simulation of turntables that allows the DJ to scratch, Ultramixer doesn’t have one. Lack of effects like pattern editor or other important effects that may be required by any DJ makes this software an avoidable option at a time when better software are available that offer much more features.
However UltraMixer has the distinction of being the best bet when it comes to Linux or Mac users.
Features like flanger, cross-fading, 31 band graphical equalizer (making precision to the mixing) etc make this software a good option for playing music in parties, but this is a strict no-no for professional DJing.
Pluses:
- Simple interface.
- Talk option that minimizes the need to manually reduce the volume while announcing on the microphone (I really love this feature!)
- 31 band graphical equalizer.
Minuses:
- Scratching is not possible.
- Effects are minimal.
There are various options available that allow the user to use the software for free or buy the license that allows commercial mixing possible – Atomix mp3, VirtualDJ

Never tried my hands on mixing songs. :D
Well, what are you waiting for?? :D
In my opinion, UltraMixer is very good for professional dj mixing, its developed for daily use, so Ultramixer has a clean and intuitive user interface without distractive features you find in VirtualDJ.
I use UltraMixer for my dj gigs, its very stable, no crashs, no bluescreens!
So from my point of use, you can recommand UltraMixer as an alternative for VirtualDJ or BPM-Studio.
