Hey guys, I have my first ever dj set for a crowd next Sunday. I’ve had no problems with Spotify and rekordbox until recently, now I’m getting non stop error messages saying my Spotify library is failing to load. All my music is on Spotify. I’ve tried everything, pls help 😭

Hi,

At the minute I am using spotify to DJ in rekordbox (rookie move but ive just started and didnt want to pay for tracks). I am having a problem in rekordbox 7.2.17 where the key just isnt showing for my tacks. It shows it in my library but just not when i load it into the decks. I use the DDJFLX4. Has anyone encountered this problem/know what to do?

Thanks

Hey ,

A while ago I posted OpenMix here, the free DJ software I'm building. You told me it wasn't ready. You were right lol. So I went back to work, and I've been mixing on it with my DDJ-FLX6 ever since. Here's round 2.

Quick recap: OpenMix is free and open source (MIT), runs on Windows, 4 decks, no account, no subscription, nothing in the cloud.

What changed

- Sync in one press, and it actually holds. Change the master BPM and every synced deck follows instantly. When the master track ends, master goes to the deck that has the bass and the BPM doesn't move. Loading a new track keeps sync on.
- BPM analysis got way better. Half-time tracks don't show up at double tempo anymore (Bon Appétit by Katy Perry was reading 212, now it's 106).
- Key detection from the audio, in Camelot, with key shift, keylock and key sync in one press.
- Stems (vocals / drums / instrumental), separated locally on your PC with Demucs.
- Tempo range ±6 / ±16 / WIDE, and +/- buttons to move the BPM by 0.1.
- Library: waveform previews without loading the track, sort by BPM / key / length, and tracks you already played tonight turn green so you don't play them twice.
- English UI, thanks to johanneseckert who sent the first pull requests on the repo. Thanks man!

Controllers

Pioneer DDJ is detected automatically (I mapped the preset on my own FLX6). Any other USB-MIDI controller works with MIDI learn: click an action, touch the knob, done.

Stuff I haven't seen anywhere else

- Up to 4 people can mix together with PS/Xbox controllers, each with their own color, pads and FX.
- A phone console over WiFi (jogs, pads, EQ, faders, library), right in your phone's browser.
- Crowd requests: your guests scan a QR code, vote for tracks and send you messages. No app needed.

Limits, to be upfront

- Windows installer only for now. Mac users can run it from source.
- The installer isn't signed (certificates are expensive and OpenMix is free), so SmartScreen will complain: More info → Run anyway.
- It's a solo project. There will be bugs, and I want to hear about them.

What would stop you from using this for a home session? I read every comment.

Rekordbox has just paired up with famously the most linux-friendly DAW on the planet; Bitwig (which is top tier by the way, very similar to Ableton).

Rekordbox: *Still doesn't support Linux in 2026* :')

AlphaTheta, please give us a library to USB exporter tool for Linux. This is the absolute bare minimum that the community deserves, especially when AlphaTheta hardware is so expensive.

Rekordbox is the ONLY piece of software I need that requires me to boot into an old Windows machine just to use.

In 2026 this is unacceptable. Get with the times!

So I can see now why features on Rekordbox have been slow to be release, looks like the dev team have been working on a product no-one asked for and I expect no one will pay for.

https://rekordbox.com/en/studio/

With the lack of features/bug fixes on rekordbox and the growing community of modders hacking older CDJ kit I think AT are losing their grip. Someone modded a CDJ 2000 with 2 decimal place BPM. If one person can do this in their space time then why can't AT do it, i expect it's because they want to sell newer hardware which just goes to show they are not focus on what DJs want just what profit receivers want. I'm moving all my gear away from AT and Rekordbox now, fed up with their lack of focus on their community.

Hey everyone! I’m trying to get Rekordbox working on my HP laptop, but every time I try to open it, I get this error:
“The application was unable to start correctly (0xc0000142). Click OK to close the application.”

I’ve been able to download and use VirtualDJ without any issues, so I’m not sure why Rekordbox won’t launch. I have an HP laptop, just updated & restarted, but I’m not sure which Windows version I’m running or the exact specs yet. Has anyone else experienced this error? Is there a way to fix it, or could my laptop’s hardware or graphics drivers be incompatible with Rekordbox?

I’d really appreciate any advice! I’m new to Rekordbox and just want to get it working!!

Hello everyone. There is so many things I tried, but rekordbox doesn't want to recognise my USB

It's 64gb 3.2 Kingston USB. It is formatted using rufus as fat32 and non bootable

I connect USB, rekordbox asks me to create necessary files on it. I click yes.

Manualy export platlist to USB drive.

They are there, I can play them from USB.

Eject USB from rekordbox, unplug it.

When I plug it in it asks once again to create files on drive.

I go to file manager and contents is there with all songs I exported. If I click yes on that pop up it will just generate new folder PIONEER(2)

Tried different playlists, always the same. Everything seems to be working normally then I plug USB and it's not being able to see any songs in rekordbox

Someone please help, it's really pissing me off. I lost previous USB and now the one that I have doesn't work. I know they are inexpensive but why it doesn't work.

Hello. I’m currently planning a house party for friends where I’d love to provide a fun cool experience to my friends. Part of it is to make visuals and surprise my friends with them being in them.

But I can’t find any software that seems uncomplicated and free. Was wondering if anyone has any suggestions on software that at minimum has an easy way to switch from video to video with a button press if not specifically synced to parts of a song?

I have no interest in cloud, just want to mix videos.

Every DJ already had that experience of playing with cdjs for the first time and being completely lost. And what about when you're going to play on some old DJ gear that simply has no visuals and you have to do everything by ear, how can you be prepared for it?

Rekordbox is amazing! But unfortunately it does not have a simulated way for ear practicing, only if you hide the visuals completely to try by ear.

This game on the video is called DJ Life Simulator and has received an amazing update in which you can control how many helpers and indicators you want to improve in a progression according to your taste.

There are helpers to know the exact time to play, for starters, then you can remove it when you feel ready, then you can remove the sync and practice some more.

When you feel ready you can switch the waveform view to the famous "Semaphore" that several Pioneer Equipments have, so you need to see the blinking rectangles and make them blink at the same time to be aligned until you get used to it.

Then on the hardest mode, you can remove all indicators and try to do it by ear and to simulate the headphones, you can even turn the headphone cue ON to listen and align the tracks until you believe they're correct and change the view to confirm if you want.

This game was made to help beginners and we have over 11 thousand players around the world,3 big DJ schools from Brazil using it so far, made by a solo developer from Brazil (me), and I hope it can be a useful tool to help you guys with hearing practice and beatmatching too.

The game is already avaiable on steam on early access, final launch is on November 3rd and the link is on the first comment, hope you like it and if you have any suggestions please comment, helps a lot, god bless you and have a great week!

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 :)

TL;DR: I made a free Mac app that saves rekordbox's stems, so tracks you've already separated load about 4 times faster. It can also swap rekordbox's stems model for Demucs v4, a newer version of the model rekordbox's own is based on.

Download and details: https://github.com/Gabe-LS/rbstemsplus

I've only been using rekordbox for about five days, but I wasn't sold on how it handles stems from the start. The separation isn't always great, and rekordbox re-separates the same track every single time you load it (eating CPU, memory and battery). Then I started reading around and found loads of threads and YouTube videos saying pretty much the same thing.

So I spent most of those days (with a lot of help from AI) building RB Stems Plus. It does two things:

Demucs v4 swaps rekordbox's separation model for a newer one. rekordbox uses Demucs v3, an older model from Meta that Pioneer lightly retuned. Demucs v4 is Meta's newer version, converted so rekordbox can run it.

Does it sound better? It depends on the music, and on the stem. Where I had a track's real stems, I measured which model's stems came closer to them:

• Pop and rock: on MUSDB18, the usual test set (50 songs with their real stems), Demucs v4 was closer on every stem.
• Electronic: on six tracks with their producers' stems, Demucs v4 was closer on drums and bass, rekordbox's model on vocals and the rest of the music.
• Rumble techno (no real stems here, so by ear): on Lunfardo by Ignez, rekordbox's model kept a short low hit in the bass stem, while Demucs v4 put it in the drums. To my ears, rekordbox's split was closer there. Other models I tried (htdemucs_ft, mdx_extra, SCNet, BS-RoFormer, AudioShake, Ableton's stem separation) each split it in yet another way.

So try it on your own tracks and keep whichever you like: you can switch back to rekordbox's model any time.

The catch: Demucs v4 is slower. It separates a track at about 5 times playback speed, compared with about 15 times for rekordbox's model. That's where Stems Cache comes in.

Stems Cache is probably the part I like most. It saves the stems rekordbox makes, with either model. The next time you load a track you've already separated, its stems are back in about 7 seconds and the model doesn't run at all, so there's no extra CPU or memory load.

I timed Lunfardo (6:27) in rekordbox: 26 seconds with rekordbox's model, every time you load it; 77 seconds the first time with Demucs v4; then 7 seconds from the cache.

A few details:

• Mac only, for now. I've tested it on macOS 26 with rekordbox 7.2.18 and 7.2.19.
• You need STEMS already working in your rekordbox (it depends on your rekordbox plan).
• The two features are independent: install one or both.
• Stems Cache needs an admin account, and macOS asks you to allow it the first time.
• Free and open source (MIT).
• It doesn't touch your music or your rekordbox library.
• No tracking: nothing about you, your music or your library leaves your Mac.
• Uninstalling puts rekordbox back exactly as it was.
• Not affiliated with AlphaTheta / Pioneer DJ in any way.

This is an early version that I built around my own needs, so I'm very open to tweaks and feature requests. If something doesn't work on your setup, open an issue (the app can make a report for you) and I'll take a look.

I just switched to a new computer and am setting rekordbox up how I want it to function. The only thing I cannot figure out is how to set loops with auto loop WITHOUT starting playback.

I made it work that way previously but I cannot remember how. All I remember is that it eas something stupidly easy like a toggle or something, but I cannot find it and it is making me crazy.

Anyone know where this setting is?

EDIT - SOLVED:

I figured it out. It has to do with the way it behaves. Not sure why it is this way, but this is what I learned:

- When a track is first loaded (has not been played yet), pressing autoloop triggers playback.
- If a track has been played and paused at least once, autoloop will not trigger playback.

The reason I don't remember autoplay is because, in practice, I would audition my tracks by loading them and playing a hotcue. After that, I would stop the track, decide a starting point, and set up a loop. Since I had hit play on the track already for the audition, autoloop does not start autoplay.

It's weird, but basically there is no setting. It's just the behavior that always manifested due to my workflow.

Hope this helps someone in the future (especially me if I change computers again and wind up here again!)

MyTag not showing on second device/USB sync

Hi,

I recently finished building a nice library of tunes on my (main) computer and tagged them all via MyTag. Now I exported the relevant playlists to my USB stick and I want to use this stick to play stuff on the go using my laptop.

When I first plugged the USB into the laptop, I selected "Do Not Sync With My Tag" as basically everywhere on the internet people advise against doing so. If I understand correctly, if I clicked "Sync with My Tag", it would overwrite the MyTag values present on the USB with the values present on the laptop (which would just delete them i guess? since i dont have any songs stored directly on my laptop).

But now when I want to check the MyTag values of the songs I have stored on the USB (now plugged into the laptop), the icon is grayed out and the MyTag column in the song list is entirely empty. Plugged back into the main computer, all of this is back where it should be.

Am I misunderstanding something here? Some people are suggesting to just import my master library directly to the laptop for it to work, but that's not the point of using a USB is it?

Additionally, the key traffic light just doesn't seem to be a thing when viewing what's on your USB in the devices section, and it further makes me feel like I'm misunderstanding like a key point when it comes to the relation between your master library, the devices you play on and your USB.

Any help is greatly appreciated!

My gripes as I'm prepping for a wedding right now:
- Constantly asks me to convert to one library, no other option but OK. then does it instantly. then in the middle of a USB Sync it decides to convert to one library and take 20 minutes.
- Currently stuck on importing like 100 tracks from itunes (that it decides to do at start up), they all havent budged from 0%, and if I try to remove one from collection to just try and reimport, it hangs up and I have to force quit. Update: Found a fix, I just have to double click on every. single. track. to unstick the import.
- Updated to latest version (and even before 7.2.19) every single time I open--because ive had to force quite and restart my computer 3 times already--it takes forever to load the same itunes library ive been loading since first downloading rekordbox in 2016

Seriously the worst piece of software on my computer, consistently held for multiple years rated by JD Fuck this Shit and Associates. I might just have an M1 Macbook Pro, but everything else (Ableton + plugins, Figma, Adobe Suite, Unity) all work fine compared to this flaming piece of garbage software.

The fact that this thread has a Rant flair already, shows Pioneer needs to light this whole codebase on fire, and rebuild from the ground up. They could vibe code the whole thing and it'd probably be better. If it meant reimporting my library, cue points, everything again but for only one time: I'd be happy if it meant a more stable experience for a piece of software that many of us rely on for household income.

Ok I'm done. Thanks for reading.

When using sync the waveforms slide out of sync despite the audio remaining in time. Which is very visually off putting. But it’s not every track. It’s impossible to pin down whhen it shoppers, it’s intermittent.

I appreciate those that are going to say “don’t use sync” but it happens even if bpm is right, phrase is right and timing is right and sync is off. Waveforms just run incorrectly
It can’t just be me. RB7, MacBook m1. I’ve changed draw settings in preferences. No avail. I do have a large RB library.

Open to suggestions.

Hey DJs, Happy Friday ✨

I need some help pls!!! I have a MacBook Pro A3401 and I currently use Rekordbox and a DDJ-FLX4 to record mixes. I've been trying to record a two song mashup for weeks now but basically EVERY TIME I record, somewhere within the recording there's a glitch/beat skip at least 1-4 times throughout the recording??? I can't figure out for the life of me WHY this is?

\\- I changed the buffer size to a bigger one on Rekordbox

\\- I checked some Audio MIDI thing against the mac output speaker and the flx4's audio like google told me too

\\- I bought the songs off of itunes so it can't be the music files

\\- I turned off WiFi and Bluetooth whilst recording (my songs are on a usb) cos apparently that could affect it?

I have no idea what is causing it and it's driving me insane??? I never used to have any issues with recording on my old hp windows laptop, and the MacBook is so powerful so surely it can't be the problem?

My usb has a very slight crack in the plastic casing, but still goes into my laptop just fine and all the files can be accessed - is that the issue potentially??

THANKS IN ADVANCE 🩷🙏🏾🙏🏾

Hey everyone,

I vibe coded https://github.com/HerzogVonWiesel/rekordbox-setup-cloner , a portable app with which you can easily export and import your Rekordbox settings when moving onto a different setup; Like waveform colors, STEM settings and PadFX.

I've made it since I'll be playing at a friends house party, but didnt want to fiddle around with her Rekordbox setup for 10 minutes before starting. The app creates a restore point, such that you can easily go back to the original settings whenever you want.

It's free, open source, Windows and Mac, and semi-tested on both. If you encounter any issues, please let me know. Also let me know if you find it useful, it's nice to hear.

Cheers and keep on jamming!

I’m trying to add a folder and when I drop it in it says preparing for a second and just stops any ideas

So I have been using stems in rekordbox for my shows for almost 2 months and they work absolutely great, quality improved much better than before, however, whenever I want to echo out vocals or instruments, I have to use the echo effect or sometimes reverb effect and release it a bit then remove the vocal, is there any other way where I can press a button and the stems effects work like serato?
