CDJ emulator update: 8 supported decks, real-time NXS2

Some time ago I posted the CDJ-2000NXS2 emulator here: the deck's original firmware running in QEMU, waveform moving, audio playing. A lot has happened since, so here's an update.

The NXS2 runs in real time now. Playback used to fall behind and stutter, now it keeps real time properly, also with two decks linked over Pro DJ Link.

More players. The same emulator now boots seven older players as well, each on its own original firmware: CDJ-2000, CDJ-2000NXS, CDJ-900, CDJ-900NXS, XDJ-1000, XDJ-1000MK2 and XDJ-700. They're experimental. The CDJ-2000, CDJ-2000NXS and XDJ-1000 already play in real time with sound, the others load and play tracks but still run below real time. I'm working on getting them all up to speed and running in real time with audio, will take some time. The README has a table of what works on each player.

Since this opens the doors for easy modification, I've been patching it. There are 6 mods so far:

- 3-band waveform (CDJ-3000 style colours)

- phrase band on the overview

- Ableton Link

- TCNet (ShowKontrol, Resolume, lighting desks)

- OSC output

- MIDI clock over the rear USB port

The mods can also be written into a .UPD for a real deck. I haven't tried that on real hardware yet, so do so at your own risk.

No Pioneer firmware is included: setup asks for your own update file and builds everything from that. Runs on Windows, macOS and Linux.

Happy to answer questions, and open for new features or suggestions.

Auto Relocate Sucks, So I Made One That Actually Works

One time I used OneTagger to give thousands of tracks treatment to get a consistent file naming system on my local files; little did I know that it would break thousands of links in Rekordbox. I tried the Auto Relocate feature only to face the horror of being faced with the dumbest tool ever. Then I sat there, staring at the screen with thousands of songs with barely changed names, unchanged metadata, yet rekordbox was unable to find any of them.

RB lets you Relocate, and if you want to re-link, you have to do it one by one. Lazy as I am, I knew it wasn't on the table doing so for days on end; then the thought came up, "what if I could just fix it my way?"

So here you go, a tool with capabilities of doing what Rekordbox can't. Fully open source, GPL 3 licensed, completely free without asking for anything back.

--

Since then I've added Hot Cue managing functionality. a browser that scans your database, shows your RB library with focus on Hot Cues. What is really cool though is that, let's say if you've re-encoded a bunch of FLAC files to MP3. One would think you'd have to re-import the new file, right?

The only issue is that re-encoding like that will add some length to the song, and therefore will drift your hot cues off the grid, but not anymore.

Safely Re-encode how many files you want, Relink them with Relinkbox, then use Cue Manager to snap those hot cues back into place, all by clicking one button.

Read more in the link, feel free to ask questions, give feedback or contribute to this project :)

Rx4 rumors told me by some dj shops in Lisbon

Hi guys, I write you because recently I travelled to Lisbon and I had the chance of visiting some dj shops, mainly because I wanted to practise in a djm v10 and cdj setup, in the shop that I booked for playing with them, I spoked with the shop guy about some thoughts I had about upgrading my home setup and he told me that he had some serious inputs from alphateta that the rx4/ax version will come before the end of 2026 so he told me to wait before buying a new rx3, any thoughts on this?
From my side I would really love a rx4/ax with bigger wheels and still two channels, and maybe send return effects as the v5?, I guess that if it had 3 channels it would be insane but I guess it is hard to happen, the only thing that really scares me is that they do the same as with the AN and put everything on the screen, I love physical buttons!!!!

What are your thoughts guys?

XDJ-RX vs XDJ-RR for outdoor gigs?

I’ve been getting booked for outdoor gigs and want to switch to a standalone system. I currently use a DDJ-GRV6 with a 2020 MacBook Air, but my laptop overheats outside, causing the music to slow down and cut out.
I found a used XDJ-RX and XDJ-RR for $750 each. Most of my gigs will be small patios and rooftops, so portability matters, but I also rely heavily on Hot Cues for phrasing and use echo reverb and spiral.
Which would you choose at the same price, and would the RR feel like a downgrade coming from the GRV6?

For anyone who wants stem separation done thru a website

https://preview.redd.it/7h1iu95qdruh1.png?width=1154&format=png&auto=webp&s=ea554acb16d96d4f4a8c9e160cf47ef0fb16dd1f

Hey all,

I’ve been following the stem mods for the CDJ-3000, XZ, AZ and RX3, and the part that kept bugging me was the prep. Separating a crate on a laptop takes ages, so I put together a small web app that does it on GPUs I have at home.

You pick what you’re playing on, drop in some tracks, and it splits them into vocals, drums, bass and the rest with Demucs. You can preview the stems in the browser before downloading. For a CDJ-3000 running cdj3k-mods, it writes the stems in the mod’s own format so they should load on the deck. For everything else, including Denon gear and DAWs, you just get the stems as separate audio files.

It’s at https://www.clouddsp.ca if anyone wants to try it. It’s free, there’s no account, and files get deleted after 48 hours. I'm still improving the load times as I go.

Happy to hear any feedback, or if this is even useful to anyone.

Upgrading from flx-4 and want to upgrade, need advice.

I have around 2k to play around with. I want the closest thing to 2 cdj 3000x’s and an a9 /club standard since thats what most of my local venues use. I mostly play electroclash, hardstyle and hyperpop. Pretty much anything but house lol. Ive been looking at an rx3 but i need a second opinion.

Question about denon’s and pioneers ecosystem.

I got a really good value for a whole denon set up but like idrk. mint condition 2 sc5000 primes and x1850 mixer. 1600 for everything. Thing is all venues near me use cdj’s and i want to be comfy with that ecosystem. Id be upgrading from an flx 4. Its either that or an rx3, good condition 1800 bucks. Can rekordbox beatgrids and hotcues transfer over to these denons and which is more worth it? Which would be better for my situation. Please help

Back DJing. Is OMNIS-DUO the right choice for me?

That’s me back DJing after years out of the game, and I’m absolutely loving it again.
I play house, proper house music, always with plenty of old school classics thrown in. I use Rekordbox and, at the moment, I’ve been using the equipment in the bars where I DJ.
The problem, although it’s a good problem to have is that a few other bars around where I live in Thailand have seen me play and have asked me to DJ for them. I don’t own any gear anymore, so it’s time to buy something.
I’m about 80% set on the AlphaTheta OMNIS-DUO.
The portability and built in battery are a massive attraction. I can easily take it from bar to bar, and being in Thailand, the idea of being able to set up pretty much anywhere really appeals to me.
One thing worth mentioning: effects and loads of extra features aren’t important to me. I hardly use them.
I keep my mixing simple. Give me a good 1 minute mix, swap the bass at the right time, make the transition clean and let people hear the bloody song! 😂 That’s how I’ve always played.
I also want to stay with Pioneer/AlphaTheta because it’s the industry standard. I’m expecting to pick up some bigger gigs where I’ll be walking into a full CDJ setup, so keeping everything familiar makes sense. I’m comfortable on CDJs anyway, but familiarity is important.
So, for anyone actually using an OMNIS DUO, especially for bar gigs:
Would you buy one again?
Any drawbacks you’ve discovered after living with it for a while?
And for the way I DJ, is there anything else around the same price that you’d seriously consider instead?
Cheers from Thailand 🇹🇭🍻

Sync manager question

Hi! I’m wondering why every time that i update a song (title, artist…) or if I add 3/4 files, when I use syn manager it takes to sync my pendrive around 90 minutes? I’m using different sandsik extreme pro duo formatted for fat32 (mbr) and I’m using Rekordbox for max 7.2.19…

Thank you

would a dxs1080 be backwards compatible with a dxs1056?

the dxs1056 is a bit harder to get since its from older hardware like the cdj 400 and mep-7000 but the 1080 looks nearly identical and are found all over since they are used in the cdj-2000's and other more contemporary gear

im trying bring one of my cdj-400's back to life, it functions ok but the select push rotary doesn't do anything when pushed/selected and it appears to be a common issue

Aufnahme über OBS

Hallo,
Ich habe einen DDJ-GRV6 und streame meine Musik über Soundcloud. Möchte meine Sets wie bisher über OBS aufnehmen, leider habe ich seit einiger Zeit eine komplett unbrauchbare Audio und bekomme sie einfach nicht wieder clean.
Hat jemand Erfahrungen damit gemacht und kann mir helfen wie ich wieder meine Sets aufnehmen kann :)
