here are the 12 arguments
Also, I dont want to just blindly create issues, but due to the new protocol having upto 6 players, it means that being "player 5" didnt work. (It came up as being pre nexus)
Hello @daffron and welcome! Thanks very much, I will definitely appreciate being able to ask you to try things once I think they have a better chance of working. Yes, there are a number of things that are going to need to change at various levels in my ecosystem of libraries and software in order to support players 5 and 6. No need to make a specific issue for that yet, unless you want to, but I haven’t started tackling it yet.
I am not working as much on this as I would like, because I am under a lot of stress right now, thanks to how badly the Wisconsin legislature (and the federal US government) is responding to the CoViD-19 crisis, and the general chaos building towards election day. But I hope to dedicate a good chunk of time working on several of my open-source projects today, I think that will even help me feel better. :smile:
Actually, since Gitter is not great as a way to track things, I will create an issue in the beat-link project about supporting six players for CDJ-3000s, and tag you there, so that I remember your kind offer when it comes time to test things. If you could attach log files showing what happens when it fails, that might help me avoid forgetting to fix some things, too.
Hello, @EvanPurkhiser and nice to hear from you! I have not seen this, no, I keep the menu items type table up to date with what I know: https://djl-analysis.deepsymmetry.org/djl-analysis/track_metadata.html#types-for-menus
I agree that looks pretty empty-ish, zero or empty-string values for everything except parent ID, which is 1. Do you know what was being requested which led to this response?
@tvrdennis_twitter My email said there was a question from you yesterday, but I can not find it in the chat history now. Did you figure out what you needed? If not, could you try repeating your question here? Did anyone else see it?
ah, I think I found it as "Playlist Writer"
Hello, @eric! Yes, that records performed tracks to a text file. If you want to do something slightly different, that code is a good starting point. There is also a section in the user guide which gives a walk through of how to build a simpler version of that tool: https://blt-guide.deepsymmetry.org/beat-link-trigger/0.6.2/matching#writing-a-playlist
Hey, @eric sorry I lost track of your question, it’s been a bit of a stressful week. The user guide walks through how to create and edit trigger expressions, please let me know if there are conceptual gaps that give you trouble. If you want something that is very close to what the built in Playlist Writer does, though (since that adds some nice UI), you might be best off just forking the project and editing the source for that.
hello everybody! i am writing you regarding a little help I need.
i want to use the beatlink with Ableton, to link the tempo from my CDJs2000 to it.
all good, I manage to do that, but since I don't own a pair of CDJs 2000 Nexus2, I can't "tell" beatlink to watch the tempo from Master.
i found a workaround in my head: create 2 triggers, one from player 1, and the other from player 2. now it's the tricky part: say i trigger the tempo from player 1 witch is playing and i have to move to the next track on player 2. i want player 2 to send the tempo information once player 1 stopped playing.
i have to do this with custom trigger enabled filter expressions.
finally here's my asking: can you please help me to do this as i don't know anything in programming Clojure or anything.
thank you and big up for Beatlinktrigger <3
Hello, @razmih12, and welcome! Unfortunately, CDJ-2000s don’t support sync, so you are going to be limited in what you can achieve, as you have discovered. Also unfortunately, I don’t have access to any of those players to try things and help write code. However, it sounds like you might already be close. When you say that you got it working with one CDJ, can you give me details about how you did that? I don’t think the newer Ableton Link feature can work, because that follows the master player, and there won’t be one with non-nexus players. So, were you using a trigger that was sending MIDI clock?
If that is what you are doing, I think you can get it to work. All you need to do is set the trigger to follow “Any Player”, and it will follow the tempo of whichever player is playing. When both are playing, it has to pick one, and I think it might just pick the lowest-numbered player. But since you are beat matching then, it should hopefully not matter. And once you stop one of them, it will be only following the other.
@brunchboy Hello! Yes, I will upgrade to nexus2 next year. I did the link procedure as I was reading in here: https://djtechtools.com/amp/2017/07/19/decoding-pioneer-pro-link-connect-cdjs-ableton-link/
I use an RME Fireface 800 to send the link to Ableton.
I tried your version with "any player" but when I preview a track quickly in cue and if it's not in the same tempo as the other player is playing, I get quick changes between the two tempos, and obviously the Ableton did it too, sadly...
So I'll just have to wait till I buy the nexus2. Thank you for your quick reply!

That’s strange. It uses the Java Preferences API, and so it depends on your OS. Since you mentioned the task bar it sounds like you might be in Windows, and I believe that means it uses the registry, but I’m not a Windows developer so I’m not precisely certain. If I recall correctly, it organizes its settings under the key
org.deepsymmetry.beat_link_trigger (yes, just confirmed that).
You can google how Java preferences work on Windows. If you can figure out where temporary directories are created, you may be able to find the log files (or check on a different machine to find the file path). I wonder if it stored window positions that are off-screen now? But it is supposed to detect that. Maybe I should add a command-line argument to clear the settings. But I would like to figure out what is going wrong in your situation.
Hi, sorry if this has been asked before but I can't see any results for it.
When using Traktor/DVS and CDJs, the tempo information (tempo slider) is detected by BLT but Ableton/Link doesn't recognise any changes. If I use a CDJ normally (no DVS) everything is as expected. Is there something i've missed? Any pointers much appreciatef

Hello, @RJBooty! This is the first I have heard anyone asking about this, but unfortunately I don’t really understand what you are trying to accomplish. Beat Link Trigger works with DJ Link Pro, and nearly all features of that protocol require you to be playing a track on the CDJ that has been analyzed in rekordbox to identify where the beats are, and so on. If you are using DVS, none of that is true right? So I would not expect anything to work.
However, Traktor itself can use Ableton Link these days, and so I would recommend you just use that directly, and ignore Beat Link Trigger. The fact that you happen to be using CDJs to control Traktor is irrelevant in this case, you’re not using the rekordbox ecosystem, so BLT is not helpful.
Hi @brunchboy , thanks for the reply!
It totally makes sense that BLT requires the CDJ to play a track, I guess in this case the 'track' is actually a timecode signal/file.
Though Traktor can indeed use Ableton Link, it isn't possible (as far as I can work out) to make traktor the Master tempo for Link. Which means you can't use tempo faders on CDJs/Turntables running Traktor DVS, as they are locked to the Ableton Link tempo.
I was hoping that there might be a workaround with BLT, as currently (if I use a CDJ in normal mode/not DVS Traktor) BLT acts as the master tempo and Live is the slave.

Yes, if you are playing a rekordbox-analyzed track, you can use BLT to control an Ableton Link session tempo, or you can allow Ableton Link to be master and control the tempo of the CDJs. That was quite a breakthrough in coding! But when you are just using DVS, I am not going to be able to do anything for you. I think that it is possible to have Traktor be the Ableton Link tempo master, but you will want to ask that on a Traktor forum for details. I have not been using it much since I moved to the rekordbox world.
I understand that a track has to have been analyzed in Rekordbox and that that's how BLT works, but as mentioned, didn't know if there were any other 'workarounds' for my approach.
If it's any help/insight, I am actually only really using 2 turntables with Traktor DVS, the CDJ doesn't need to be DVS, the issue is having Traktor as the master

Thanks for the replies, and of course for BLT! (Using it in a separate project, as it was meant for, and it's fantastic!)
And thank you for the kind words, I always love hearing from people who are using these projects.
Please let me know if you do get the chance!
Weirdly, have just come across this...(I have next to no understanding of code/programming, but maybe you can make more sense of it!)

Oh, sad news, that article says I am wrong, and for some reason Native Instruments have chosen not to allow Traktor decks to update the tempo of the Ableton Link session. So that’s something you’ll need to take up with them. But I’m afraid they are having such problems with profitability and layoffs, that it’s not likely to be a development priority for them any time soon. :worried:
Maybe someday that author will figure out how to release a portable version of their program that runs on any Mac, and ideally code-sign and notarize it so it runs without complaint (but that requires paying for an Apple developer program annual membership, so they may not. I do, in order to allow Beat Link Trigger to run without complications, but it’s a bit eccentric that I spend $105/year on that.)
If you have a Mac and you’re willing to trust an unsigned, non-notarized Mac binary (I wouldn’t recommend that personally) you could try following his instructions on how to reset the quarantine bit to run it. But going from MIDI clock to Ableton Link is a bit icky in the first place, Link is so much better than MIDI clock. Are there any other DVS programs you could use that have better Ableton Link support? I wonder if Mixxx does these days?
It looks like not yet: https://bugs.launchpad.net/mixxx/+bug/1625050
Ironically, before I got sucked into figuring out how to integrate with the rekordbox beat grid, I built a way for my lighting software to tie into the Traktor beat/bar grid: https://afterglow-guide.deepsymmetry.org/afterglow/mapping_sync.html#syncing-to-traktor-beat-phase
Standard NI being a pain!
Yeah not sure i'd use that Binary, I have other ways of sending MIDI clock and it's just nowhere near as good, as you say, as link.
It's only really traktor I use as I bought it many moons ago. I'll have a dive into some other DVS.
Might be a silly question, but would Rekordbox DJ/DVS work with BLT? The Rekordbox information won't be coming from a CDJ, but from the Rekordbox App on the Mac (I guess what i'm asking is if it's routable, somehow)
Afterglow looks interesting and a potential solution so I'll dig into it, and as it's to do with lighting might be super helpful for what we're doing.
If it's of any interest to you/others, this whole project is to gain (pretty much just) timing information from the CJDs/Turntables from Traktor/DVS system, send out (synced) CV information from Live and (synced) video from Resolume, to modular video eurorack system, final output to a projector and a TV wall. Currently, using BLT as it was meant to be used is perfect (albeit only using it for bpm information at the moment) so big thanks! Hopefully further down the line we'll look at using more of the triggers/BLT system to create something almost entirely automated
Afterglow is probably too experimental to be worth investing a lot of time into unless you are keen on building a really unique algorithmic light show using Artnet and DMX. :smile:
