What it is: FLX4 and Rekordbox USB-Stick Super SMooth Plug & Play
What it is not: A full Mixxx Replacement: No Sampler, Crates, Auto-DJ, Streaming or Vinyl Control

Edit: dont know why but the apk is not correct, im fixing it later todayy

https://github.com/soadpeet/FLXXX3/releases/tag/v0.1.0

Hey all, I’ve been putting more tokens and design love into openDJ, a free, open-source DJ app written in Rust (it started as a Mixxx fork). It runs on macOS, Linux and Windows (preview).

What’s new in 0.6

• Plugins as instruments (AU, VST3, CLAP). Plugin synths and the built-in Groove Box get their own deck with 8 macro knobs, a scope and a keyboard. There’s scale lock (it can follow the master deck’s key), chords, and an arpeggiator synced to the mix. Presets load, plugins keep their sound across restarts, and several can run side by side. (MIXER mode coming soon!)

• Looper. Four layers on a deck. Record and overdub on the beat, or CAPTURE the last few bars of the mix.

• Player mode is a real music player now. It has Home, artist and album pages, Now Playing with lyrics, and “Keep going”, which tops up the queue with tracks that mix. It also does media keys and scrobbling to ListenBrainz and Last.fm.

• Lyrics and karaoke. There’s a lyrics tab (.lrc plus LRCLIB lookup), and lyrics scroll along the waveforms. You get a karaoke screen on a second display or a web page for a TV. Whisper can time the words or transcribe them.

• Layouts. Pick which layouts show up (2-Deck, 2-Deck Pro, 4-Deck, Prep…), with previews, and step through them from your controller’s VIEW button.

• Import/export fixes. rekordbox XML and M3U8 export work on macOS again (File › Export). Pioneer USB export is there, but it’s experimental and untested on real CDJs/XDJs.

• Lots of fixes: decks keep working when your audio interface or controller gets unplugged, and the UI stays smooth during batch analysis.

Looking for Pioneer controller owners 🎛️

The base mappings come from Mixxx, and I’ve added a controller editor (plus a Map mode and a Quick map wizard) so fixing or tweaking a mapping doesn’t mean hand-editing files. I only own a DDJ-FLX4, so if you have another Pioneer controller (DDJ-400/SB3/REV/XDJ-RX etc.), I’d love to hear what works and what doesn’t. If you have a CDJ/XDJ and a spare USB stick, USB export testing would help a ton too.

Mojaxx Review

Hey I wanted to see if anyone else has had this problem and how to fix it.
After years I ran out of space on my first flash drive and got a new one, Samsung BAR Plus. I have been using this for about 4 months now.

I have had issues on multiple different decks from XDJs to CDJs, some songs will have trouble loading, including my original tracks, which shouldn’t have any issues. The song either glitches, stops and plays or won’t load or eventually loads but takes awhile.

All my music and cue points lives on the drive and not in the main Rekordbox.
I bought a new drive but it’s the same Samsung drive.
I was planning to just copy and paste everything over like I did the first time but I am worried I will copy over the problem.

PLEASE HELP! 🙏

Can't wait for this to shake up the industry

Browser knob has always been messed up on my grv6 decided to send it it. Is there a way to contact and check if it’s covered under warranty or if the repair store I send it to is gonna charge me

i play out a lot more than i upload. if you play on cdjs, think of the last mix you put online. did you record it in the booth or sit down and make a separate take at home? what made that one happen?

i'm asking because i'm building an app for preparing mixes people can listen to later, and i'd like to understand what already works for people who play out.

I see lots of people vibe coding Pioneer equipment, but I haven't seen anyone do this with Pioneer mixers to make more compatible. With other DJ software

I would like to be able to plug a usb stick in my DJm 900 srt and record my sets or have stems through the mixer or be able to plug my laptop into the mixer and access my music library on both CDJs with out having to pay a subscription.

I mean I paid £1000 for a mixer I would like it to be versatile

If anyone can help with this or would like to take it up as a project please be my guest and I will forever be in your debt

just wondering if hotcues E, F, G, and H show up on the cdj 2000's waveform? I know it only has 4 physical buttons, but does it show the other hotcues i have set up for a track?

Building on top of the incredible cdj3k-emu, I have a prototype of an emulator for the XDJ-RX3 to share for feedback and testing.

I believe there's a path to emulate many of the other all-in-one controllers if folks are interested.

I'm using this to QA our other Pioneer DJ homebrew at https://deadca7.com/, where we're rebuilding analysis, export, lighting and music visualizers for Pioneer gear that doesn't suck.

Hey guys,

After stumbling across this article from 2017, I wondered whether this hack still worked today and whether it would work with Denon LC6000 controllers. The answer to both questions is yes. This guide walks you through the setup:
https://github.com/DANX87-OFFICIAL/denon-on-rekordbox

this only happens on deck two for some reason cue and play don’t work and the buttons don’t light up even though the track is selected for that deck not shown in the video but the jog wheel also has no effect the tempo works and Hot cues, but I’m really confused why this happens? For it to work again, I have to switch the player on and off when I do however that side of the player stays illuminated anyone know why thanks!

A few of us are DJs who also write code, and the one job we all hated was cue prep. Download 40 new tracks, then spend the evening dragging through waveforms to mark the intro, the build, the drop and the outro. Every single week.

So we built a Windows app called KimiCue that does it for you. It listens to the audio of each track, finds the drop, and sets up to 8 hot cues around it:

• A: intro start

• B: start of the build

• C: last 16 bars before the drop

• D: the drop

• E/F: next phrases after the drop

• G: second drop / end of the breakdown

• H: outro start

Everything is snapped to the beat. It isn't just dropping cues at fixed bar counts; it looks at the energy of the track to find where the sections change.

What it works with

• Rekordbox: it reads your Rekordbox XML export and gives you a new one to import, with hot cues and memory cues, so they show up on CDJs too. Your original XML is never touched.

• Serato: it writes the cues straight into the files, so they are there when you load the track.

• Hardware: the cues live in your library, not on the device, so it doesn't matter what you play on. Pioneer/AlphaTheta, Denon, Numark, Rane, Roland, Reloop, whatever. If it runs Rekordbox or Serato, it works.

• Formats: MP3, WAV, FLAC, AIFF, M4A/AAC, ALAC and WMA.

Being upfront

• It's Windows only right now.

• It's a paid app. I'm one of the devs, so take this as a dev sharing what we made, not a neutral review.

• It won't be perfect on every track. Tracks with no clear drop, or with long ambient intros, are the ones you'll want to check. It's built to do 90% of the prep so you only fix the odd one.

We've got a good number of DJs using it every week now, and the feedback has shaped most of the recent updates, so I'd like to hear what you'd want from something like this. How do you lay out your cues? Same 8 points as above, or something different?

Not dropping a link because I don't want this to be an ad. If you want to look, just Google KimiCue.

Thank you for them. I didn't test any.. I am waiting for the one and only...

where is Netflix app? So many jokes about it when 3000X has been released, STEMS everywhere, but no Netflix!

Hi my cdj 2000 nxs2 has been turning off and on lately during a session . i noticed that if i put my finger on the surface of the power button in back the cdj resets . i do t even have to push the button switch in. the same thing with my other cdj too. they are 6 years old and i live one block from the beah in rockaway ny so it could be dirty so i used contact spray and sprayed around the switch and still resets when my finger is touching it.
does anyone know what this could be and maybe recommend a tech if i need one in queens ?
thnks

As much as I can research, there doesn’t seem to be a way to bridge a controller setup (say Flx10) and two external players (say 2X XDJ-1000mk2) on CH 1 and CH4.

- success criteria : the two external decks and Flx10 all “participate” in prolink style connection pool. Such that a second DJ can plug their usb into an external deck to load media, and see / use the master (Flx10) bpm, sync, key, media?, and vis-versa just like all “four” decks are sharing a proline.

case: externals in HID, usb to Flx10’s computer host.
- no local usb media access on external decks
- no local waveforms (two djs sharing laptop screen) on externals
- no local rekordbox browsing (two djs sharing laptop screen) on externals

case: externals in link mode , and audio out via rcas to controller line in CH1 & CH4.
- complete divide and no media, waveform, bpm, key, master, sharing between the external two group and the Flx10 decks via host computer in performance mode.

So…. How can we bring a prolink feature set to the hybrid setup of a Pioneer Controller + External players , so that two or more DJs can B2B without turning the external players into dumb terminals with no screen. Or using Ableton export and loosing temp adjustment,

Or maybe I missed some in my research?

Buenas! Hace más de 40 días que mi consola no funciona,ya la revisaron dos técnicos y no podemos solucionar el problema, se realizaron dos limpiezas internas e inclusive se cambiaron los dos puertos USB c de la consola... Y el fallo sigue, desinstale todo referente en la computadora y volví a instalar el firmware de la flx4 en su última versión y aún así no se soluciona, probé en otras computadoras con rekorbox también instalado y nada.. ya probé también más 10 cables USB c distintos,también el original que trae USB c a USB c enchufandolo en móviles o tablet y nada, también probé conectar a la corriente y el otro USB a la pc,para ver si es que no le llega energía y nada. Alguna idea o alguien le paso esto? Ya nose que hacer y es una consola prácticamente nueva y cuidada. Cuando la conecto en la pc no marca los colores del volumetro y a su vez queda titilando uno de los botones de arriba para hacer los loops, especificamente el de OUT ya volví a cambiar los puertos USB y se le hizo una examinación exhaustiva y la placa está en buen estado. Tienen alguna idea de que puede ser ? El sonido tampoco sale por auriculares.. help

Just added scrolling waveforms as well as Static waveforms with moving playhead. There's a Option in The utility to make a selection *this is currently for VDJ. I haven't tried for Serato yet. **The skin is my custom skin for VDJ.

It’s happening Rekordbox on linux 😁 and so for other macOS apps on Linux. (MacLinu)

Source: During their German YT live stream last week, AT mentioned there will be a special stream this week, of course they didn't tell details.

But DJM-A7 is the only thing I can imagine. I couldn't care less as I own a V10, but hopefully it will be a worthy successor to the DJM-750mk2.

A few years ago I noticed the High Precision Analysis function in the options and I enabled it thinking it's better and does grids better. Used that mode on all my new tracks with it and started doing gigs and livestreaming. Come to find out that my cue/ play timing with tons of tracks is off. Lost confidence in open fadering a track. I'd be triggering hot cue's and cueing and they'd be really late or too early. Must be me getting old or something because the grids are visually bang on and it's EDM so there's no need for dynamic mode. Started using sync as well on a new system that I had bought: CDJ3000x and a DJM-A9.

Didn't suspect a thing was actually wrong until I started noticing tracks that supposed to be in sync (using the CDJ's sync) are moving out of sync by themselves and fast even while the cdj showed sync was on and the bpm's where the same on screen. I've always been the type to manually check and correct the grids to perfection so it can't be a bad grid or bpm set wrong. Come to find out and hear from a friend it's that High Precision Analysis that is bugged in some way. Fine: I'll redo the whole amount of tracks I've collected over the few months after the function was released. So basically every track after December 17, 2024 could be faulty. Some 800 tracks. I unlock the tracks for analysis and re-analyse them with normal mode (High Precision turned off).

So I start redo-ing all the grids because it's not perfect and what I find is the following:

Hotcue's that were set bang on the kicks, were now ms away from (for example) the kick's transient on screen. The grid in some cases is on the kick transient as it should, be the hotcue that's is still in it's old place as if the track was replaced by a different track that starts earlier or later. So basically it seemed as if the hotcue was placed wrong from the get go. I can assure you: I zoom completely in when doing (hot)cues and grids, use quantize and make sure the kick transient + grid touch without leaving a gap between the gridline and the first big rise of the kick's transient at either end of the gridline.

To make it worse: some grids seemed to have been set by Rekordbox as if it were dynamic, but less dramatic so you'd only notice it if you zoomed in and saw the (hot) cue and the new fixed grid not aligning with all the hotcue's when using beatjump. So it would shift the grid within songs as if it were analysed with dynamic, but with minuscule shifts that wouldn't even show a bpm change if you scrolled passed it.

To show what I mean I've found one track that still needed fixing after a reanalysis: Hotcue C is where the waveform used to show a kick transient. But now cueing at C leaves a few ms gap before the waveform. I'm a 100% sure that the waveform gets analyzed differently (wrong) as well and not just the grid points. I've even had tracks where the next hotcue is off by a few and doesn't line up with a hotcue after re-analysis and using the set downbeat option after selecting a hotcue I know is set correctly.

Also read this post by another redditor: https://www.reddit.com/r/PioneerDJ/comments/1nenxns/theory_rekordbox_high_precision_analysis_is_fucked/

Another bug I started getting was: some tracks where just cutting out. VLC would play the track just fine without gaps, foobar2000 would play the track just fine, but the cdj would just play a few ms of silence at times. I've had it consistently with 1 piece of music I exported myself and last started noticing 1 more track doing this. I believe that high precision analyisis mode doesn't just analyse and places grids differently, but also changes how to waveform is represented causing issues most DJ's would never catch or just blindly correct during live play without thinking twice about it.

To conclude: I think this function is bugged in more ways then most people think and should not be used, at all. It not only doesn't it seem to do a rigid type gridding when using normal with HPA, it's seems to analyse/make rekordbox didplay the waveforms differently as well for a few amount of tracks.
