DSS DJ is a professional audio mixing tool that comes with a couple of powerful features. It is based on one-click beat-matching and synchronization.
The user interface may seem crowded at first glance, especially for less experienced users. Since this program has been mainly developed for power users, beginners might have some difficulties adjusting to the DSS DJ environment in a short time.
The main menu offers you access to configure DSS DJ, but also to start recording a session (exported as a WAV file), while the browser enables you to manage songs, as well as create and modify song lists.
In the 'Configuration' menu you can select audio output, enable beat matching when automatic DJ-ing is on, and others.
The two decks are panels where you can play and loop songs, set cue points, scratch, include real-time effects, equalize, and kill frequencies, while the mixer resides in another panel, used to crossfade between decks, guide the signal to master and monitor outputs, to synchronize and mix songs.
You can basically play with bends, spins, reverse play, brakes, pitch, master tempo, an accurate automatic BMP counter, a beat-aware loop engine, a cut-off filter, DSP effects, and many more.
DSS DJ uses a fairly small amount of CPU and memory resources. The only downside when it comes to navigation is the fact that you cannot move the interface, but only maximize it.
In conclusion, DSS DJ is a great tool for mixing audio tracks, and it has many useful features even if it may represent a challenge for beginner users.
