Hi, I prefer beatgrids, bmp calculations, and 2 player mode in recordbox…so once done - I put my USB into Denon Prime Go - and most of the beatgrids shifted to left 1/10th of a beat - out.
So I tried another way - output to xlm, import into engine dj - same again - beatgrids out, some BPMs wrong, and all cues green.
How do I get around this?
Analyse all your tracks in the Engine Desktop software then use their sun manager to export this music and database to a drive.
Denon products work best when they’re accompanied by the dedicated software, much the same as Pioneer products work best with their software.
Another thing I’d suggest is to update to the latest firmware on your players (if you haven’t already) and try again. I think there’s a file you can delete in the database that will initialise the Rekordbox import again.
Raise this as a bug if things don’t align as they should. I’ve seen reports of beatgrids and cues not aligning properly occasionally under some circumstances.
The import tool should work as intended and that’s to get someone who usually plays on Pioneer DJ gear a working solution if they find Prime players in a booth. It’s a ‘pretty much a quick fix’ should you need it but it should at least work properly.
We have several topics about the same issue:
The cause of the issue seems to be that different softwares use a different audio codecs to decompress audio files causing slight variations in the end result. Uncompressed audio files like wav should not be affected by this so I guess that is another point for using those.
Fix for this is either to use something like Lexicon that can mass shift beatgrids by a set amount of ms during database conversion or use the beatgrid editor on the player to shift it manually before playback.
This should be stickied 
It’s really not good enough. 30% are messed up - the rest fine - so can’t use a “do all at once” trick in Lexicon.
There should be a tool stating what encoders are needed for import, that match the export. It’s all done on the same pc so should be same.
Nightmare. This will make me move to pioneer. EngineDJ is so much worse than recordbox so why would anyone want to use EngineDJ.
Not according to this post 
You have lost me completely here tbh… Codecs are built in the software (Rekordbox, EngineDJ) so not sure how can you force one software manufacturer to use exactly the same one as their competitor 
Anyway, if the workarounds provided or the solution to just use the library management software that is meant for your hardware is unacceptable for you, I guess you will have no other choice but to sell your Prime GO and buy a equivalent standalone system from Pioneer.
I think you can post your sale ad on the forum, nobody will mind. 
Anyway, all the best
For the record, ive been using Rekordbox for years, and just as many of my tracks are out of line in there as they are in any other software… what you can do in Engine is quickly edit your grids whilst mixing to line them up, that way it never becomes an issue because any track you want to play is corrected within 5 seconds of loading it.
The latest update of Engine desktop has improved downbeat detection, so maybe re-analysing them all will work.
There is a known issue for .mp3 files where some DJ softwares consider the file header to be ‘audio’, causing a 26ms misalignment in their beatgrid. This causes some DJ database converters to have shifted beatgrids. For more info: DJ collection converters - DJ Knowledge Base
However, I don’t think this is the problem we have with EP. It seems that EP is doing it’s own beatgrid analysis on all tracks and completely ignores the Rekordbox/Traktor/etc beatgrids when loading tracks from those collections. I believe this is the cause because the ‘grid’ column is empty when viewing any collection. ‘grid’ becomes once the track is analyzed or loaded onto a deck. This means EP generates it’s own beatgrid from scratch. If it was using the Rekordbox/Traktor/etc grid, then that column would have been checked once you imported the Rekordbox/Traktor/etc collection.
Example: here is a playlist from my Traktor collection (which I synced/updated) which I imported into EP. I loaded track 10 onto a deck which took 1-2 seconds as EP generated the beatgrid. All other tracks have the ‘grid’ column empty, even though they have been gridded in Traktor. Interestingly enough, EP seems to import the key and cue points… but not the grid…
To further my suspicion that EP doesn’t import external grids: the EP manual has been updated between version 2.2.0 and 3.4.0: all mentions of importing beatgrids from Traktor/Rekordbox/etc have been scrubbed. Beatgrid import incorrect for Traktor or Rekordbox - #7 by Akuro This is extremely frustrating to me as all the marketing and documentation lead me to believe importing beatgrids from Traktor/Rekordbox/etc. was supported. Yet, Dennon seemed to admit this wasn’t the case… and haven’t added the functionality since. Meanwhile, all of us who thought Dennon would be an affordable alternative to Pioneer, still have thousands of tracks gridded in Rekordbox/Traktor/etc. Redoing every single beatgrid (even if EP beatgrid analysis was PERFECT) is simply not a realistic option. And paying for a subscription service to convert between formats causes things to become pricier again lol.
This has not been my experience with Serato Library imports
My Serato grids are imported to Engine DJ
I don’t use Traktor nor Rekordbox for library management.
Yes the grid remains empty when I add my serato as well but that does not mean my Serato grids are not going to be used.
What happens is that the first analysis pass in Engine will check for missing things - eg if BPM , Key or Grids are already in the file it will skip those and analyse for other things.
Then the grid column is populated
I have enabled Automatic Analysis, so once I add new tracks it’s analyzed immediately because I know it’s going to use the info from my Serato to do them:
Reanalysis on the other hand is a full analysis.
