① Library browsing is possible on the product when a library is created using the "rekordbox" music management software included with the CDJ-850. Library browsing is a function allowing you to search for and select music files by categories (album, artist, track, playlist, history, etc.) specified with rekordbox.

② In addition to the above, music files can also be selected using libraries created on the MEP-7000 with Library Editor (library creation software for the MEP-7000).
