PCDJ DEX 3
PCDJ DEX 3 is a full-featured DJ software solution that supports audio, video, and karaoke mixing all in one application. Developed by Digital 1 DJ in the United States, it has been a trusted name in the DJ software space since 2000 and is particularly popular among mobile DJs, event hosts, and karaoke professionals who need a reliable all-in-one solution.
The software features a familiar dual-deck interface with large waveform displays, a central mixer section with crossfader and EQ controls, and a comprehensive music browser. DEX 3 supports 2 or 4 deck layouts with independent volume, EQ, effects, and transport controls per deck. Beat detection is automatic, and the sync feature keeps tracks aligned for smooth mixing.
Video mixing in DEX 3 is a standout feature. DJs can mix music videos alongside audio, with support for a wide range of video formats, transition effects between video sources, text and image overlays, and output to a secondary display for venue projection. The video engine runs smoothly even on modest hardware, making it practical for mobile DJs who project music videos at events.
Karaoke functionality is deeply integrated. DEX 3 supports MP3+G (CDG), ZIP, and video karaoke formats. The karaoke mode includes a singer rotation list, a songbook browser, key changing for singers, and on-screen lyric display. For professional karaoke hosts, DEX 3 offers the most complete karaoke management system of any DJ software, eliminating the need for separate karaoke applications.
The software supports over 75 DJ controllers out of the box, including models from Pioneer DJ, Numark, Denon DJ, Hercules, and others. MIDI mapping allows customization for additional controllers. An external audio interface can be used for headphone cueing and multi-channel output. DEX 3 also includes recording, broadcasting, and a selection of audio effects.
PCDJ DEX 3 is available as a one-time purchase with free lifetime updates — a rarity in today's subscription-driven market. This pricing model, combined with its reliability and all-in-one audio/video/karaoke capabilities, has earned it a loyal following among working DJs who need dependable software for paid events. The PCDJ Karaoki product is also available as a karaoke-only version for hosts who don't need DJ mixing features.
