Pioneer DDJ-400 vs. DDJ-FLX4 - Is an upgrade worth it?
Pioneer DDJ-400 vs. DDJ-FLX4 – Is an upgrade worth it?
Pioneer DDJ-FLX4:

The Pioneer DDJ-400 and DDJ-FLX4 are somewhat close when it comes to what they offer in terms of features. FLX4 offers quite a few new creative solutions such as the Smart CFX or Smart Fader effects, and its visual design is quite a bit different from the plain black outer casing of the DDJ-400.

In general, as the price of both units is currently pretty close, getting the DDJ-FLX4 seems to be a better idea for a few additional features that it offers, and presumably for longer official hardware support.

Another thing is, that the Pioneer DDJ-FLX4 supports both Rekordbox and Serato DJ software, and moreover, it will soon also have official support for quite a few Android and iOS DJ apps. This isn’t the case with the DDJ-400, which will officially only work with Rekordbox (and is also supported by Virtual DJ).

Because the devices do not differ by much in terms of the mixing-related features though, the upgrade from the DDJ-400 to the FLX4 might not be the best idea if you’re already a a happy owner of the older 400.

Is the Pioneer DDJ-400 discontinued?

Pioneer DDJ-400 has officially entered the legacy Pioneer DJ gear collection with its discontinuation in late 2022.

Yes, the Pioneer DDJ-400 was recalled by Pioneer in late 2022 and is now officially deemed a legacy product. The controller has been moved to the archive section on the Pioneer DJ website and new units are no longer being produced.

With that said, if you own or plan to purchase a new DDJ-400, you have to keep in mind that it will become more scarce as the months go by, and you can’t count on it being supported for much longer in terms of official software updates and hardware service.

The Pioneer DDJ-FLX4 is the official replacement for the DDJ-400, and it carries over all of the functionalities of its predecessor while adding some more interesting solutions to the device’s feature set.

If you’re still interested in getting yourself a new Pioneer DDJ-400, you can either search for the leftover units at your local music equipment stores, or attempt getting one second-hand (for example over on Ebay).

All in all, while the DDJ-400 has been commissioned, it’s still a really capable and feature packed entry-level device that might be worth looking at if you find it at a good price.

Where does the DDJ-FLX6 stand?

Pioneer DDJ-FLX6 is the first DJ controller released in the FLX series lineup in November 2020.
Pioneer DDJ-FLX6 is the first DJ controller released in the FLX series lineup in November 2020.

Pioneer DDJ-FLX6 is a 4-channel entry-level DJ controller released back in November 2020. It’s the first Pioneer DJ controller from the FLX series, released two years before the FLX4. It’s known from its quite affordable price and two somewhat gimmicky features, namely the two Merge FX knobs and the Jog Cutter scratch automation functionality.

How does the Pioneer DDJ-FLX6 compare to the DDJ-FLX4? Well, first things first the FLX6 is a larger, 4-channel DJ controller with full-size capacitive jog wheels, and the FLX4 is much smaller, featuring 2 mixer channels and jog wheels which size can be best compared to the ones present on the DDJ-400.

While their general feature sets don’t differ that much, their form factor does. In general it’s up to you whether or not you’d like to have this kind of entry-level feature set on hand in a smaller, newer and somewhat more portable device (the Pioneer DDJ-FLX4) or in a slightly larger and more professional-esque form (the older Pioneer DDJ-FLX6).

Remember that the older FLX6 is also missing the CFX effects and the Smart Fader function which are present on the FLX4.

DJ software compatibility

What about the DJ software support? Well, the DDJ-FLX4 seems to be in the lead here.
What about the DJ software support? Well, the DDJ-FLX4 seems to be in the lead here.

In terms of the software compatibility these devices are a bit different (and the DDJ-FLX4 comes off as a somewhat more versatile one).

The Pioneer DDJ-FLX4 is first and foremost compatible both with Rekordbox and Serato DJ software. It unlocks full versions of Rekordbox, and allows you to use Serato DJ Lite once it’s plugged into the your computer. If you’d like to use Serato DJ Pro however you will have to do a paid software upgrade.

Here you can read much more about the main differences between the two versions of Serato DJ software: Serato DJ Lite vs. Pro (12 Most Important Differences)

This is quite notable, as currently there aren’t many DJ controllers that are able to support both Serato and Rekordbox. If you’re interested in a few devices that do give you that possibility, check out this neat list that we made: 5 DJ Controllers Compatible With Both Serato & Rekordbox.

Moreover, the FLX4 also will support Virtual DJ in the near future judging by the information we were able to gather from official Virtual DJ forums.

Yet another great news is that the Pioneer DDJ-FLX4 is said to be fully compatible with the upcoming Rekordbox DJ performance app which will be released somewhere in 2023.

The older Pioneer DDJ-FLX6 unlocks and supports both Serato DJ Pro and Rekordbox but has much better affinity with the latter (mainly in terms of audio the FX controls).

When it comes to the Pioneer DDJ-400, it officially supports Rekordbox DJ and can also work with Virtual DJ reasonably well. Currently there is no way to use the DDJ-400 with Serato.

Both DDJ-400 and FLX4 will unlock the full versions of Rekordbox when plugged into your computer, but only the FLX4 will also work with Serato DJ Lite (and Pro if you decide to upgrade).

Price and availability

Pioneer DDJ-FLX4 and DDJ-FLX6 is in general readily available both at official resellers stores and the official Pioneer DJ store over on Amazon.

The verdict – Should you get a new DDJ-FLX4?

The Pioneer DDJ-FLX4 is a great device, however not exactly a large step up from the DDJ-400's feature set.
The Pioneer DDJ-FLX4 is a great device, however not exactly a large step up from the DDJ-400’s feature set.

So, is getting a new Pioneer DDJ-FLX4 worth it? Should you upgrade from your DDJ-400? Our take on that is as follows: while the new and updated DDJ-FLX4 is certainly the better option if you don’t own an entry-level DJ controller just yet, if you do own a DDJ-400, it might not be worth to swap it for the FLX4 if you don’t exactly need the new Smart CFX, Smart Fader features and the updated looks which are the main selling point of this device.

While you won’t be disappointed with any of these, we’d advise you to go for the Pioneer DDJ-FLX4 if you’re currently planning to purchase your very first DJ controller.
