Pioneer DJ Announces rekordbox version 4.2.1 and RMX Effects Plus Pack!

rekordbox version 4.2.1 Packs New Features

RMX EFFECTS Plus Pack for rekordbox dj Offers Fresh Creative Possibilities

Torrance, CA (August 2, 2016): Pioneer DJ is bringing new features to its free music management software, rekordbox. Available today, rekordbox version 4.2.1 delivers a new way of easily recording analog sound sources, so you can effortlessly manage digital and analog music in one library.

Using its audio analysis technology, rekordbox detects the silence between tracks and creates a separate file in your library for each one, so you can press play and record a whole album from an analog source to individual tracks without resetting the recording in between songs. Thanks to the new Normalize function, when DJs use recorded tracks, their volume will automatically standardize, so there’s no need to edit levels in advance. Pioneer DJ is also making it easier to find the perfect track to play next in a set with its new Matching feature. Users can audition tracks in rekordbox and mark the ones that mix well together, then when DJing on certain multiplayers (CDJ-TOUR1, CDJ-2000NXS2), they can choose to display the matched tracks with the track that’s currently playing (firmware update required). 

Pioneer DJ is also releasing the new RMX EFFECTS Plus Pack for rekordbox dj. Taking the Scene FX from our RMX hardware – effects units used by DJs and producers for live performances and track-making – the Plus Pack brings exciting new ways for DJs to unleash their creativity and make unique sets.

Additionally, to further improve the accessibility of rekordbox, the application now supports all languages supported by Mac OS and Windows, including Hebrew and Arabic.
