Pioneer DJ hit the ground running with this one, following the massively popular DDJ-400 the best selling entry-level DJ controller, this is the next in line, you could of even called it the DDJ-400 MK2, but pioneer decided to refresh this brilliant DJ controller with a new name as well, this is the DDJ-FLX4. The new controller really does offer a lot of bang for the £££, with REKORDBOX DJ software included, and on top of that this controller comes with Serato DJ LITE. So you can check which software works for you. Not to forget this will work with iPhone and android. So all bases are covered. Just choose your device, be it a mac/laptop or phone and you are in the mix. 

The DDJ-FLX4 is an affordable unit that inherits key traits from the professional layout of the DDJ-400 – a standard for entry-level controllers – but its user-friendly design makes learning to DJ easier. There’s a choice of DJ software to mix music with, including free use of Performance mode in rekordbox for Mac/Windows. And when the major update to rekordbox for iOS/Android comes out in early 2023, you’ll be able to use the DDJ-FLX4 with your iPhone, Android smartphone, iPad, or Android tablet. Serato DJ Lite is also free to use with the controller, and you can upgrade to Serato DJ Pro if you buy a license or take out a subscription. All these software options give you the choice to play music files stored on your device, as well as tracks from TIDAL, Beatport Streaming, Beatsource Streaming, and SoundCloud Go+ (paid subscriptions may be required).

You’ll find it easy to start DJing when you get your hands on the DDJ-FLX4, even if you’re a complete beginner. The design is clean and user-friendly so you can find your way around the controls, and you’ll find plenty of tutorials in rekordbox to guide you through the basics. There are two brand-new features that make it easy to create professional-sounding mixes too: Smart Fader for effortless transitions between two tracks, and Smart CFX, which applies combinations of effects to the music with the turn of a single knob.

When you’re ready to share your performances with friends and followers, the DDJ-FLX4 is the perfect piece of kit. Its USB audio output of the sound from the microphone means you don’t need external equipment such as a mixer or soundcard to add your voice to your mix. Instead, the sound from the microphone is output from the controller along with the music, so you can easily share your set via a stream from a single computer

rekordbox and Serato compatibility
You can use the DJ software rekordbox or Serato DJ Lite for free by connecting your PC/Mac to the DDJ-FLX4 to complete your DJ setup. And if you want to upgrade to Serato DJ Pro, you can buy a license or subscription for the premium version of the software. 
Multi-device support
Whether you want to connect to a PC, Mac, iPhone, iPad, or an Android phone or tablet, the DDJ-FLX4 is versatile in its design. Even better, if you use the controller with rekordbox for iOS/Android when the update becomes available in early 2023, you’ll be able to connect to your device via Bluetooth® or USB cable. So, there’s nothing to hold you back from giving DJing a try.
User friendly portable design and professional layout
The layout of the controls on the DDJ-FLX4 makes it easy to learn to DJ and is inherited from professional Pioneer DJ products. Everything is simple to use and neatly arranged, which also makes the controller compact enough to take anywhere you want to practice or perform.
Brand-new Smart Mixing features
Don’t know how to mix? Don’t worry, you can get started right away with the Smart Fader feature, which automatically adjusts the volume, bass volume, and BPM of the music so you can smoothly transition from one track to the next by simply moving the channel faders or crossfader. This means you can have fun straight away and get a grasp of other fundamental DJ skills such as EQing. Plus, with Smart CFX, you can put your own stamp on every song by simply turning a knob to apply a combination of effects that will add drama to the sound.
Seamless integration with selected streaming services
rekordbox is compatible with a different choice of streaming services. So, depending on the DJ software you use, you can pick from millions of tracks available on the TIDAL, Beatport Streaming, Beatsource Streaming, and SoundCloud Go+ platforms (subscriptions required) and mix them together on the DDJ-FLX4. You can even use all the controller’s effects and performance features to spice up your favorite songs and create your own sound.
USB audio output for microphone sound
The DDJ-FLX4 makes it simple if you’re keen to MC or sing over the top of your sets. You’d usually need a separate mixer or soundcard to blend the audio from the microphone with the music before inputting it to your computer or device, but the DDJ-FLX4 mixes the audio for you. So, you can connect the controller to a single device and hear the sound of your mix together with the sound. This also makes the DDJ-FLX4 an ideal choice if you’d like to live-stream your sets because you can do it all from one device.
