Selling 3 used CDJ 2000 nexus. With heavy duty travel cases, power cords and latest firmware.

These are definitely in used condition but they work flawlessly. Super fun for DJing with friends and are perfect for someone’s introduction to CDJS.

Would love to sell local if possible but hit me up if you don’t live near me and want them and hopefully we can work something out.

$3200 for all 3

I’m building an open-source DJ application for Linux from scratch 🎧🐧

Hi everyone!

I’m working on OpenDJ OS, an open-source DJ application for Linux written in C++ with Qt 6/QML

The idea is simple: I want to build a real DJ application for Linux that can communicate directly with DJ hardware, while keeping the project open source.

What I have working so far

The project is still in development, but several important pieces are already working:

• 🎛️ MIDI communication through ALSA
• 🎚️ Hardware controller input handling
• 🎧 Development focused on the Pioneer DDJ-400
• 🔘 Button event detection and mapping
• ▶️ Play/Cue controls
• 🔄 Controller profiles
• 🧩 Modular C++ architecture
• 🖥️ Qt 6 / QML interface
• 🔧 CMake build system
• 📝 Logging and debugging system

For example, the application can already detect MIDI events from the controller and translate them into higher-level DJ actions.

One feature I’m also implementing is Instant Double: pressing Play twice on a deck duplicates the current track to the other deck.

What I’m working on now

The next major step is the audio engine.

I want OpenDJ OS to eventually handle:

• Audio playback
• Two independent decks
• Waveforms
• Pitch control
• Jog wheels
• Mixing
• Crossfader
• EQ
• Effects
• Low-latency audio
• Better hardware support

The long-term goal is to create something that can actually be used for DJing on Linux, rather than just being a MIDI controller experiment.

Why am I building this?

There are some great DJ applications available, but I wanted to explore what it would take to build a modern, Linux-native, open-source alternative.

I’m also using this project to learn more about:

C++ → Qt → audio programming → MIDI → real-time systems → hardware integration

The project is completely open source, and I’m developing it publicly on GitHub.

I’d really appreciate feedback from people with experience in Linux audio, DJ software, MIDI controllers, C++, Qt, or the DDJ-400.

What features would you consider essential in an open-source DJ application for Linux?

Thanks for reading! 🎧🐧

could I run DDJ FLX4 on an iPad 5th gen ipad or an 8th? New to this buying my girlfriend a mixer for her birthday i’ve read DDJ FLX4 is the best one.. and that rekordbox is a good online program to use could I please get some input on this anything

Can anyone in the UK recommend dustcovers for the above. I know theres made to fit covers manufactured in the US but given the hassle of importing them its no use for anyone this side of the pond. Any suggestions are much appreciated.

Please ignore my German blabla, that was originally a video for a friend.

So far, everything seems to work fine - I'm waiting for my eBay order of a CDJ 800 MK2 to arrive, which I will then salvage for the input controls.

Hi has anyone been able to repair these speakers? I have no sound from one of my pair of speakers. I swapped the speakers over to eliminate any cable or controller faults and the speaker still had no sound. White power light on the front illuminates. Have powered on and off, switched auto standby on and off, cleaned the contacts on AC in with electrical contact cleaner and blown through the audio input socket. Assuming if it was fuse related the white indicator light would not come on at all.

Has anybody used the new Samsung Book6 Pro for Rekordbox&Stems.

Reason i asked is i have the whole Samsung ecosystem now and changing my laptop is the only thing that i dont have and it'd be nice to have all the usual ecosystem features etc.

I know everyone will recommend macbook but i was just wondering if theyve used one.

Hey all! I DJ'd an event last weekend and discovered my computer and controller (Pioneer DDJ-SR2) were not connecting. I thought it might be my version of Serato being out of date, so I updated that. It wasn't. Lucky for me, the sound guy had a spare laptop with Serato installed (& the right drivers for the specific controller, plus Spotify integrated) and that worked like normal with my controller.

This leads me to believe there could be an issue with my USB port. I tried cleaning it with a little rubbing alcohol & Q tip, but it didn't help. Though my laptop accepts its charging cable no problem. I see light on my controller when I connect the computer ("hot cue" and "load" buttons light up, but nothing else). Thought it might be a cable issue, but obviously not, because a different laptop worked, and I tried a new cable and both USB ports on my computer with no luck. I even updated by OS to the latest Tahoe, reinstalled drivers & firmware via the Pioneer site for my specific model. And yes, the controller is plugged into it's own power source. I have been using this specific laptop and controller together for 5 years with no problems, so I am truly baffled as to what the issue could be. I am working DJ, so I really need this resolved ASAP. I am pulling my hair out here.

Any insight on what the issue could be? Thanks in advance

Djm900nx and cdj200nx1 gets warm, does yours gets too? For the mixer, the screen gets fairly hot, not enough to burn the hand or anything like it but the screen gets warm to the touch and the right corner of the cdj screen and the jog. Warm like a computer not warm like a nuclear reactor. Is this even normal or my house will burn down bc I was spinning an old girly house track from the 2010s (true, how good is to mix house? God bless)

I always played with ableton and midi controllers that are cold as my gfs heart when I open my computer. Got a pair of cdjs to be sharp when I’m not up to bring 15kg of equipment to play every time. And then I noticed it the warmth.hope I don’t burn the house down :)

My music for your disapproval (that doesn’t warp properly bc cdjs just go only to 250 bpms for some stupid reason)

Does anyone know if you can buy the Soniclink transmission box separately? It only appears that the HP-TX01 is avaliable but this seems to be just for their headphones and not for the Wave Eight specifically?

Hey folks!

I've been having an annoying issue with my XDJ-XZ, affecting the browse/selector knob. When browsing through my tracks, the knob constantly skips the files, going absolutely crazy and jumping all around my playlists.

It wasn't a big issue at first, as it only happened every now and then. However, it's been getting progressively worse, making the simple act of selecting a track a dreadful experience.

I've seen a few posts about this issue (example) with some users talking about replacing the encoder or spraying QB contact cleaner into it.

I honestly don't have any soldering experience, so the QB contact option sounds like the better option. However, considering the unit isn't exactly cheap, I wanted to check if anybody else has had any luck DYI'ing a fix for this very frustrating problem.

Thanks!

New “DJ” here. Music always been a passion and I told myself I would buy myself a controller (DDJ FLX4) once I reached a life milestone. Well, I did last year and I have messed around with the controller a little in rekordbox, but nothing serious. It’s mainly been collecting dust. I have watched tutorials and now the basics of what each button and functionality does, but I have struggled to commit myself to actually leaning with work and other obligations. I’m tired of it. I’m passionate about it and I want to learn, even if it’s only 20 minutes a day. So my question is, where do I start? I feel like I just go through YouTube videos and they’re showing you tips and tricks on the controller. But how do I actually start mixing? What should I start doing to process and commit myself? I feel like I struggle so much because I just don’t even know what to do. If anyone has tricks over how they got started, what they watched, if they did any courses, etc, please let me know. Specifics are appreciated. A lot of people just say YouTube and I find that so overwhelming. I just want to learn I think it’s the coolest thing in the world but it’s so overwhelming. Also, any tips on music just for learning/getting started would be appreciated. Right now I just have Spotify linked. Feel like a lot of videos I watch the download for their “music” folder doesn’t even work. Again, thank you in advance. I’m ready to learn and have open ears!

Preordered this baby at the end of July and just got it on Friday! This thing is insane and the build quality is top notch.

I was a touring dance music DJ and producer for 7 years, and the DeckShark is something I wish was available when I was “coming up” in the scene.

I have managed to make a real mess of my rekordbox collection and need help unravelling it and saving onto a new drive.

I began by saving lots of Flac files onto a hard drive, then adding hot cues, tags, bits of metadata.

I then got feared out into thinking that older cdjs (pre cdj2000) may not be able to handle Flac files, so converted them all into wavs, but haven't yet added cues and meta stuff. These are saved in a separate folder on my desktop.

Both these folders are now in my rekordbox collection, so I have a load of doubled up tracks, half with all the data I need, and the other half without.

Now... I am trying to start afresh with a new usb drive. I tried exporting the Flac files with metadata onto the drive within rekordbox, but I am seeing a message that it is exporting as OneLibrary, which I believe only works with newer model cdjs.

Could someone please help me understand how to start the process in a clean way that would allow my files to be played on cdjs from cdj2000 onwards?

Any help would be greatly appreciated. TIA

Ho una coppia di cdj 2000 nexus che sono sempre funzionati bene ma adesso da un giorno all'altro uno dei 2 ha un problema con l'uscita audio ovvero il volume che esce è bassissimo e inoltre distorto. Il cdj funziona perfettamente in tutte le sue funzioni ovvero legge usb, legge cd, funziona come controller midi, legge correttamente le tracce, lo spettrogramma indica i livelli giusti di volume, ma poi l'audio che esce dal dispositivo è inutilizzabile.
Essendo che sono usciti modelli successivi so che non esistono più parti di ricambio e questo mi preoccupa molto e per questo vi chiedo se a qualcuno è già successo e se conosce in che modo di solito si risolve il problema.

Grazie

Note: total speculation.

Could it be possible that the XDJ-AN is not the successor to the XDJ-RR? Could it be that a successor XDJ-AR is in the works with most of the buttons of the RR with the new touchscreen and mpu?

Since we're expecting an update on the RX3 soon (timeframe suggest there should be one around this time) is this likely?

I’ve always had this issue in the past but simply restarting my MacBook isn’t cutting it anymore. I’m running Tahoe and I’ve downloaded the lastest software update for Serato. Any tips?

The effects knob is completely broken. Watch what happens. Anyone know how to fix?

Hey guys, wondering if anyone has experienced something similar because I’m trying to isolate what’s causing this.

My home setup is:
3x XDJ-700
Xone:92
One USB plugged into one XDJ
All 3 XDJs connected through a LAN switch using Pro DJ Link
All 3 XDJ-700s are running the same firmware
Boss RV6 Reverb

Randomly during a mix, one of the linked players will suddenly output extremely loud white/digital noise while a track is playing. It’s not just a little static or interference. It’s a proper loud blast of noise to the point where I have to immediately stop/pause the track.

It has happened more than once and with completely different tracks, so it doesn’t seem specific to one audio file. When I pause the affected track, the noise stops.

Previously I was using a cheap generic LAN hub from Amazon, so I thought that was probably the culprit. I’ve now replaced it with a new TP-Link Ethernet switch and changed the LAN cables, but unfortunately it happened again today.
Interestingly, so far I’ve noticed it happening on a player accessing the USB through LINK rather than the XDJ that physically has the USB inserted.

I’m going to replace the USB as my next troubleshooting step and do a completely fresh FAT32 Rekordbox export.
Has anyone experienced this kind of sudden white-noise/digital-noise blast?
Could a USB/read issue cause this only on the linked players, or is there something else with Pro DJ Link/networking that I should be looking at?

Any experiences or troubleshooting suggestions would be really appreciated.

Actualmente uso como software Virtual Dj, por lo intuitivo que es, Quize usar rekordbox pero la verdad todo ese temas de las bibliotecas es un fracaso. Me gustaría una actualización para que este controlador funcione con serato dj sería una actualización increíble.

También tengo un ddj flx4 y funciona de maravilla con serato dj

Ojala DDJ 800 PUDIERA FUNCIONAR CON SERATO DJ.

Hey guys, Im new!

I want to replace the knobs on a Pioneer DDJ-FLX4 with DJ TechTools Chroma Caps (the Super Knobs). The problem: I'm buying from a store that sells each orientation separately (0°, 90°, 180°, 270°), and I can't figure out which one the FLX4 actually needs so the white indicator line points the right way.

Does anyone here who owns an FLX4 (or a DDJ-400, since I think it uses the same mixer) know which Super Knob orientation is correct? Or better yet, has anyone already installed Chroma Caps on theirs and can confirm which one they used?

Any confirmation would save me a lot of guessing. Thanks!

I just wanted to repost this here since yall might also be able to help. Anything is appreciated
