PCDJ DEX 4 for PC: How to Download & Install on Windows

Want to mix music like a club DJ, host karaoke, or play music videos from your laptop? This pcdj dex 4 download for pc guide shows you how to get the software on Windows 10 and Windows 11 and try it free. PCDJ DEX 4 is a professional DJ mixing program with four decks, automatic beat matching, AI-powered stem separation, and support for video mixing and karaoke, all in one package.

PCDJ DEX 4 is the current version of PCDJ’s DJ software, with the latest release being DEX 4.1. It is built for working DJs who need reliable mixing, for mobile DJs who host weddings and parties, and for beginners who want a full-featured program without a monthly fee. It works with MIDI controllers, timecode vinyl, and streaming services, and its free trial lets you test the full program in 30-minute sessions.

1. What Is PCDJ DEX 4?

PCDJ DEX 4 is a DJ software application for Windows that mixes audio tracks, music videos and karaoke files. It gives you four decks, so you can mix two songs while a third one is cued up and a fourth is ready, and it detects tempo, key and beat grids automatically, so tracks stay in sync without constant manual adjustment.

The 4.1 release adds AI track analysis that finds the tempo, beat and downbeat, detects the structure of a song, sets cue points automatically, and rates each track’s energy and mood. It also suggests the next track to play, which helps when you are building a set on the fly. The program supports DVS timecode vinyl from Serato, rekordbox and Traktor, works with a wide range of MIDI controllers including the RANE Four, and can stream music from TIDAL.

2. Key Features

  • Four-deck mixing: mix up to four tracks at once, with beat grids, sync, key detection and automatic cue points.
  • AIUnmixEQ stem separation: split a track into vocals, drums and instruments in real time, and apply effects to each stem separately.
  • AI track analysis: automatic tempo, beat and downbeat detection, song-structure detection, energy and mood ratings, and next-track suggestions.
  • Video mixing and karaoke: mix music videos and host karaoke with CDG and MP3+G files, synced lyrics and a dedicated karaoke mode.
  • DVS and controller support: timecode vinyl support for Serato, rekordbox and Traktor, plus broad MIDI controller support including the RANE Four.
  • Automix and recording: automatic mixing for background sets, built-in recording, streaming support, and a rebuilt effects section.

Tip: let the AI analysis finish on your whole music library before your first gig. Analysed tracks load with beat grids and cue points already set, so your first mix will be far smoother.

3. System Requirements

  • Operating system: Windows 8.1, Windows 10 or Windows 11 (also available for macOS 10.15 and newer)
  • Processor: Intel Core i5, i7 or i9, or AMD Ryzen 3 or better
  • RAM: 8 GB minimum, with 16 GB recommended for music libraries over 300,000 songs
  • Storage: 200 MB of free disk space for the program, plus room for your music library
  • Graphics: a dedicated graphics card with at least 512 MB of memory, or 1 GB for 1080p video mixing
  • Audio: a DirectX or ASIO-compatible audio interface for the best sound quality
