What's new in rekordbox Ver.1.5.4
●MEP-4000 is supported.
*This product is on sale in limited areas, such as South America, India and China.

About rekordbox Version 1.5.4
Version 1.5.4 is only for MEP-4000 and new rekordbox users. Version 1.5.4 disables gapless playback for MP3 files encoded with the LAME encoder on players such as the CDJ-2000. Disabling gapless playback for MP3 files encoded with the LAME encoder in Version 1.5.4 will shift existing beat grids, loops or cue points of mp3 files encoded with the LAME encoder that have been analysed and adjusted with an older version of rekordbox. The offset value depends on the sampling frequency of the file: 24ms (in the case of 48kHz), 26ms (in the case of 44.1 kHz). However, it does not alter the audio play back on the CDJ's just visually inside rekordbox, therefore you do not need to reanalyse your tracks and redefine the beat grids, loops or cue points.
Pioneer will provide a tool to automatically adjust the beat grids, loops or cue point data in a future update. We recommend that you wait.
Thank you for your understanding.
