UltraMixer
UltraMixer, as the name suggests, is a mixing program aimed at DJs. Fitted with two channels, a mixer, and a 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 may find it helpful to familiarize themselves with the different elements. The use of typical features like the crossfader, equalizer, or cue is just as expected on a regular mixer. The UltraMixer library is well-organized in a tree structure, allowing you to keep all your different tracks in a way that suits you best.
However, the installation process is long and awkward, likely aimed at encouraging users to purchase the more advanced, expensive version of UltraMixer. Within the download, there are three versions: professional, basic, and free. To activate the demo, you'll need a key, and the process takes too long.
Overall, UltraMixer is a powerful DJing application, but the frustrating and time-consuming installation process to access the free version may deter many users.
