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.

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.

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!

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'm using Rekordbox 7 on Windows and want to clean up my music collection. The source folder has around 5000 files, MP3s. I'd like to sort them into more consistent folders, tidy up filenames, and update the track titles and genre tags too.

My main concern is keeping the existing cues, loops, beat grids and playlists. I don't want to end up with duplicate entries or have to reconnect thousands of tracks one by one.

If you've done a cleanup like this, how did you handle it? Does Auto Relocate work well when both the folder and filename have changed, or would you tackle those separately?

Also, when updating titles/tags outside Rekordbox, how do you get those changes into the library without overwriting edits you've made inside Rekordbox (memory, hot cues,...)?

I haven't changed anything yet. I'll back everything up and test a small batch first, but would appreciate hearing what worked for others and anything to watch out for.

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.

I’m actively DJing for 4 years now, after a long break. For the first time I said I will stop using VirtualDJ or DjayPro and go with Pioneer gear and software. I bring my own equipment to the bars I’m playing because theirs are not well maintained.

Well it fucks me every time. Version 7.2.18
Yesterday Rekordbox decided to not show me the library browser, at all. I had to stop music and restart multiple times.

I have an M2 MacBook so there is no issue with computing power.

- I get glitchy waveforms
- I get waveforms that disappear at random times and instantly reload again.
- I get corrupted USBs and databases
- Search in library is unstable. I do not understand if it always searches for titles or artist name etc
- I have had stems stop working multiple times.
- I have had tracks not playing on my headphones.

I have never had those issues with VirtualDJ and so much cheaper hardware (controllers)

Sometimes Rekordbox reminds me of Serato. Serato has also been proven unstable for me.

Is there something I’m missing?

Hi All!

I have had two separately purchased SanDisk Ultra USB 3.0 64GB drives become severely corrupted(?) or completely bricked while exporting after updating to Rekordbox 7.2.19.

Both USB drives ejected themselves during the export process and showed errors about "missing" files that were not actually missing. This did not happen when I tried exporting with an older version, such as 7.2.16.

The USB power-saving settings were not enabled on either of the devices I have tried connecting these drives to. I have tested them on multiple computers and USB ports, with the same result.

I'm not sure if this issue only affects SanDisk USBs or other brands as well, but my Kingston USB exported successfully without any problems.

I have now had to submit RMA requests to SanDisk for both sticks because, after these incidents, neither USB will stay connected. They seem to be completely bricked? Only staying connected for 5–10 seconds at a time before automatically ejecting/disconnecting. The USB drives are not hot to the touch and do not appear to be physically damaged, burned, or otherwise broken.

Hopefully, SanDisk will approve the RMA for my previously working USB drives that are now essentially paperweights...

Please let me know if anyone else has experienced this issue. And, for everyone else, please be careful until it has been confirmed whether the new version of Rekordbox is causing this or not.

 

TL;DR:

I was exporting from Rekordbox v7.2.19 to two separate SanDisk Ultra USB 3.0 64GB drives when both of them ejected by themselves on separate computers and on separate occasions. Now, neither of them stay connected to any PC, laptop, or other USB port for more than 5–10 seconds before disconnecting/ejecting automatically.

I would love to have this version of Rekordbox as a backup on my laptop. I searched all over this sub and the internet, and could only find a download link to a third party website hosting the Windows version.

Pioneer / AlphaTheta / Rekordbox removed the install files shortly after a post went live here praising 6.8.5 as one of the best bug free versions of Rekordbox. Now they only link to 6.8.7 (I have this already).

If anyone has the 6.8.5 Mac OSX installation file, please reach out or upload it. Thanks
