UltraMixer, as the name suggests, is a mixing program aimed at DJs. Fitted with two channels a mixer and library, it allows you to store your tracks and play them consecutively, adjusting sound settings along the way.
UltraMixer's interface is clear although first time DJs will probably find it handy to get grips with the different elements. Use of typical features like the crossfader, equalizer or cue are just like you would expect on a regular mixer. The UltraMixer library is well organized in a tree structure, and allows you to keep all your different tracks the way you're most comfortable with.
The installation process is long and awkward however and is probably aimed at getting you to purchase the more advanced, expensive version of UltraMixer. Within this download, there are three versions: professional, basic and free. You'll need a key to activate the demo, and the process takes too long.
UltraMixer is a powerful DJing application but the awkward and lengthy installation process to access the free version will frustrate and annoy many.
