Is Pioneer DDJ-400 Discontinued? (What’s Next?)
First things first – the size & weight

In the picture above you can see the actual side-by-side size comparison between the Pioneer DDJ-FLX4 and DDJ-FLX6. When it comes to the weight of these controllers, the FLX4 weighs around 4.63 lb (2.1 kg), and the FLX6, around 8.38 lb (3.8 kg) – so almost twice as much.
Pioneer DDJ-FLX6 – DJ Controller Overview
As you can see in the supplied image, the Pioneer DDJ-FLX6 is closer in size to higher-end DJ controllers such as the Pioneer DDJ-1000. The Pioneer DDJ-FLX4 on the other hand is almost the exact same size as its predecessor – the Pioneer DDJ-400.
While none of these devices are exactly portable when it comes to their sizes, as you will see in a while, the FLX4 is (will be) compatible with an upcoming Rekordbox DJ app.
Jog wheels – main differences

The capacitive jog wheels on the Pioneer DDJ-FLX4 are the same size as the ones present on the DDJ-400 – so around 5″. Their surface is a little bit less of a “fingerprint magnet” than the ones on the DDJ-400 and the DDJ-FLX6 but other wise in terms of sheer functionality these are close to the same.
The Pioneer DDJ-FLX6 has two 8″ jog wheels which are almost the exact same size as the ones present on Pioneer CDJ-2000/3000 players. Don’t let them fool you however, the jog wheel platters on the FLX6 are not mechanical – they make use of the very same capacitive touch detection mechanism that most entry-level DJ controllers utilize.
In summary, the Pioneer DDJ-FLX6 has the slight advantage of bigger jog wheel size and the LED virtual needle indicator in the middle of the platter.

FX controls – pretty similar
In terms of audio FX controls, both devices make use of a traditional Pioneer DJ “Beat FX strip” approach in which all main FX controls are located on the right side of the mixer section.
Both DDJ-FLX4 and FLX6 feature much simplified Beat FX implementations which while pretty pleasant to use, don’t come close to the Beat FX strips on the Pioneer DJM mixers (and this is expected at these price points).
In that matter, in terms of basic audio FX controls the FLX4 and the FLX6 are rather similar (and so is the DDJ-400).
Where the devices do differ however, is where the additional audio FX features come into play. The Pioneer DDJ-FLX4 has its unique Smart CFX and Smart Fader functions, while the Pioneer DDJ-FLX6, has the exclusive access to the Merge FX & Jog Cutter features. More on these right now!
Smart CFX & Smart Fader on the DDJ-FLX4

There are two features that are unique to the new Pioneer DDJ-FLX4. These are the Smart CFX & Smart Fader functions.
Smart CFX is similar to the Pioneer DJ Color FX – it enables you to set different creative pre-made audio FX macros to the CFX knobs on the mixer (the knobs under the low EQ knobs).
Here are all the available Smart CFX effects as of now: Phantom Echo, Reflect Echo, Mobius Echo, Vaporize, Noise Chopper, Cyber Jet, Cyber Pitch and Twister.
All these have been recently covered in a video by DigitalDJTips, so you can head over to it for a quick presentation on how they actually sound.
The other feature – the Smart Fader has to do with the FLX4’s crossfader.
When you press the Smart Fader button, you will be able to perform software assisted track transitions with automatic tempo changes alongside with automated echo FX. This feature works the best with tracks that actually differ in tempo by much. It’s quite a nice gimmick!
Both these features are entirely exclusive to the Pioneer DDJ-FLX4 as of now.
Merge FX & Jog Cutter on the DDJ-FLX6

Pioneer DDJ-FLX6 has its own unique features, an these are the Merge FX knobs and the Jog Cutter mode.
Starting with the Merge FX knobs (explained in more detail here), they are in essence there to make transitions between tracks with vastly differing BPM easier (similarly to the Smart Fader on the DDJ-FLX4).
When you activate the Merge FX knob by pressing it, you’ll be able to turn it to use one of a few advanced audio FX macros that will help you to transition out of the track you are currently playing. There are quite a few combinations of the Merge FX with Rekordbox, much less with Serato DJ.

The Jog Cutter mode allows you to mimic scratching without you touching the crossfader – it automates its complex movements for you.
There are a few jog cutter scratches you can make use of – you can choose each of these by activating jog cutter mode and moving the jog wheel platter to one of a few zones. You can read more about the jog cutter mode here.
In all honesty, the jog cutter mode can be really finicky and hard to time well at times. If we were comparing the additional FX features directly, we would absolutely take the Smart CFX on the DDJ-FLX4 over the access to the Jog Cutter function available on the DDJ-FLX6.
Compatible DJ software

Pioneer DDJ-FLX4 is compatible with both Rekordbox and Serato DJ. But there is a small catch here.
FLX4 works with Serato DJ Lite out of the box, but to use it with Serato DJ Pro, you would have to purchase a software license separately – keep that in mind, as the Lite version of Serato is really limited in comparison to the real-deal Serato DJ Pro.

In terms of Virtual DJ, on the official Virtual DJ forums, there are already rumors about the device becoming compatible with VDJ software somewhere later this year. As this is the replacement for the ever-popular Pioneer DDJ-400, it’s only natural that support for DJ software like Virtual DJ and Mixx will come sooner or later when more devices become available on the market.
Pioneer DDJ-FLX6 on the other hand, is also compatible with Rekordbox and Serato, but this device actually will unlock the full version of Serato DJ Pro when plugged into your computer.
With that being said, the support for features such as Merge FX and Performance pad mode labeling and functionality are much worse when using the Serato DJ ecosystem with your DDJ-FLX6. Better stick to Rekordbox for best results!
Mobile devices support?

The USB-C port located on the back of the device is prepared for the mobile DJ app support. There is a rumored Rekordbox DJ Mobile App coming soon so stay tuned for that!
We can also find a charging port and an Android “mono-stereo” switch on the back of the DDJ-FLX4 – this might indicate that: the FLX4 will be able to support mobile DJ apps while being simultaneously powered from an external power bank, and it will be compatible with Android OS to some extent.
The presence of the Bluetooth LED on the front panel of the DDJ-FLX4 is also notable. The situation with mobile devices support should clear up somewhere near the end of the year.
Pioneer DDJ-FLX6 doesn’t officially support any mobile apps.
Pioneer DDJ-FLX6-GT?

After the release of the Pioneer DDJ-FLX4, the older DDJ-FLX6 actually got an updated look with the following release of the Pioneer DDJ-FLX6-GT.
Pioneer DDJ-FLX6-GT – Did Something Change?
While this one is a simple re-skin of the original FLX6, it introduces nice change to the jog wheels finish, which makes them more pleasant to use (and less fingerprint-prone). It’s also nice seeing that the FLX series seems to be finally getting some attention from Pioneer DJ.
Price and availability
Both Pioneer DDJ-FLX4 and Pioneer DDJ-FLX6 are already readily available in a handful of online stores and marketplaces. Here you can check their availability both in the official Pioneer DJ Amazon store and on Ebay.
It is to be expected, that due to the high demand for Pioneer DJ entry-level devices (which we certainly know from the DDJ-400 shortage episodes) the Pioneer DDJ-FLX4 might get sold out pretty fast.

Pros & cons
Let’s quickly go over all the advantages and disadvantages of the Pioneer DDJ-FLX4 and the FLX6. Then we’ll get straight to the summary and the final verdict!

Pros:
- The reasonably priced successor of the Pioneer DDJ-400.
- Smart CFX & Smart Fader features.
- Kept all the core DDJ-400 features and added more.
- Compatible with both Rekordbox & Serato DJ.
Cons:
- Quite an average integration with Serato DJ software.
- Doesn’t unlock the full version of Serato DJ Pro anyway.

Pros:
- Full size 8″ capacitive jog wheels.
- 4 mixer channels on board.
- Merge FX & Jog Cutter features.
- Comes also in a graphite-colored variant.
- Compatible with both Rekordbox & Serato DJ (unlocks Serato DJ Pro).
Cons:
- No XLR outputs (just like on the FLX4).
- A quite clunky FX strip implementation.
- Still a bit limited when compared to only slightly pricier devices.
The conclusion – which one should you get?

To sum it all up, the Pioneer DDJ-FLX4 is just as great of an entry-level DJ controller as its predecessor – the Pioneer DDJ-400. It’s a device that’s great for beginners, and it’s probably one of the best choices on the market right now when it comes to DJ controllers for people who want to smoothly get into DJing while not breaking the bank.
Pioneer DDJ-FLX6 on the other hand, is a small step up from the DDJ-FLX4’s feature set. It has 4 mixer channels and full-size 8-inch capacitive jog wheels on board, while still maintaining a very similar control layout to the one present on the FLX4. While the FLX4 features its brand new Smart CFX & Smart Fader FX, the FLX6 has its unique Merge FX & Jog Cutter FX combo.
If you can justify getting a larger 4-channel device for around double the price of the basic DDJ-FLX4, you can consider going for the FLX6.
Our advice here however, would be to either start off with the FLX4 and possibly upgrade later, or go straight for the higher priced semi-professional DJ controllers. The price of the DDJ-FLX6 (and the price difference between the FLX4 and the FLX6) hardly justify the purchase.
If you’re considering getting the Pioneer DDJ-FLX6, you could also go all-out and get yourself the best DJ controller in the league – the Pioneer DDJ-1000. Here is our detailed comparison of the DDJ-FLX6 and the DDJ-1000 if you’re interested: Pioneer DDJ-FLX6 vs. DDJ-1000 (Direct Comparison!)
