Furthermore, the program enables you to easily drag-and-drop your favorite tunes into your current playlist. Once you finished making your selections, you can start constructing your mix.
All you need to do in order to edit a track is to double-click on top of it, and press the Play button. You are, then, able to set the beat levels for each loop you make (4, 8, 16, 32), shrink/expand beat intervals, shift the whole Beatgrid left/right, double/halve the BPM value (beats per minute), and many more modifications.
The program also conveniently comes with a built-in search engine, which helps you locate any audio file that you are looking for by simply selecting the search filters (title, artist, BPM, label, etc.), and afterward entering the keywords. You will obtain a fast and accurate result in just a few seconds.
