Advanced Playlists Editor for Traktor Pro (or APE for short) has been designed to ease the process of managing Traktor's collection while providing a set of advanced (yet very easy to use) tools that allow operations that cannot be performed with Traktor nor any other tool (such as iTunes).
Please note that this version of APE is still considered a beta which basically
means that (a) not all
features are implemented and (b) those that are,
are not guaranteed to work.
Also, the documentation included with this release is not complete but should
help you get started and take advantage of the many options provided by APE.
