DEX 4 is professional DJ Software for MAC and Windows that allows you to go far beyond simple DJing. The most versatile do-it-all DJ software available, DEX 4 enables you to intuitively mix music, music videos and host karaoke with precision. DEX 4 is the only DJ software with all the features you require to make any every gig a total success.

With our beat-grid based automatic beat mixing, AIUnmixEQ (stems), and key detection it's easy to blend tracks, allowing you to focus on the other aspects of your mix. Your audience will enjoy superior sound quality made possible by DEX 4's industry-leading custom sound engine whether you're mixing live or using automix.

Transport and DJ Mixer Controls

DEX 4 makes it easy to mix everything. The DEX 4 user interface and transport controls work much like CD Decks and include advanced mixer controls much like you find on high-end physical DJ mixers.

Real-Time Stems with AIUnmixEQ

Using PSDJ's exclusive AIUnmixEQ feature, DEX 4 can isolate individual parts of a song using machine learning, a flavor of AI. The industry refers to it as stem separation, or as PCDJ like to call it, real-time "unmixing". The feature works with any standard audio, video, or karaoke tracks, including supported streaming services such as TIDAL or Beatsource LINK. Enable the feature in DEX 4's options and use the EQ knobs and kill pads to smoothly separate songs into three isolated stems: Vocal, Instruments, Drums/Percussion.

Advanced Media File Browser

DEX 4 includes an advanced media file browser for all your music, music videos and karaoke files. iTunes playlists are also imported automatically so you can start mixing immediately. The included library filters allow you to view only the file type you want to work with, and the fast search feature displays results as you type. Create custom playlists or generate lists from directories on your hard drive. The 'History' list can be filtered by date so you can go back and re-use a previous mix set. Album art and color coding makes it easy to find the song/s you’re looking for. New "List Mode" allows for a more traditional column-style layout.

100+ Compatible DJ Controllers

DJ Controllers provide hands-on tactile control over DEX 4, allowing for more creativity while mixing. Over 100 DJ controllers from popular DJ equipment manufacturers are supported, which means zero-configuration required so you can get into the mix right away. Use multiple DJ controllers at once — DEX 4 will even detect when a controller is connected in real-time.
