Hi everyone, I’m having trouble with Mp3tag and need some guidance. Here’s my situation: My audio files are in FLAC format. The YEAR field in my files is in the format YYYY-MM-DD, for example 2021-05-15. I want to transform and distribute this information across several fields so that Djay…

I’ve spent a lot of time looking into it (even downloaded djay Pro) and came up with the following: Please delete RELEASEDATE → RELEASEDATE in Mapping/Tipos de etiqueta, matching a tag to itself seems to cause it to remove itself. [fe4d5e141837f81ac61be265b9d5d8a6068ece23_2_344x236] Admitted…

You can throw all this into the same Action: Try this: $regexp(%year%,(\d{4})(?:-|/)(\d{1,2})(?:-|/)(\d{1,2}),$3/$2/$1), it’ll capture 3 groups of numbers, separated by non-captured groups of - or /, then place them in a new order. To get the month value transferred over to TRACK, use an Actio…

[image] ohrenkino: Wasn't that already solved in this thread: Yes — in that post they solved extracting the month (MM) from the YEAR column (DD-MM-YYYY) and putting it into the Track field so metadata would be read correctly by Rekordbox. However, I have migrated to DJAY PRO and it appears to…

[image] Sithko: which I believe breaks the whole action chain. At least the $mid() function for TRACK should work as before as it simply looks at position no. 6 in the date string and takes the character and the next one. That would be the month, I think.

It didn’t work for me — I’m sharing the configuration of my tracks below. [image] If I run this action group, it leaves everything exactly as I want it (except that it doesn’t convert the “-” into “/”). [image] [Captura de pantalla 2025-10-29 a las 19.17.04] [image] And this is the action …

The key is being able to replace the “-” symbol with “/” in the YEAR and RELEASEDATE fields, and then have the TRACK field copy the MM value from YEAR.

All this confusion is because in DJAY PRO I can create smart playlists using filters, and I want to use the Track Numberfield (TRACK in Mp3tag and DJAY), Year (YEAR in Mp3tag and DJAY PRO), or Release Date (RELEASEDATE in Mp3tag and DJAY PRO) for that purpose. However, in the FLAC files I have, the Y…

I’m confused by your images as there’s different tracks with different years etc. between them, so I can’t see exactly what’s supposed to be correct :sweat_smile: Is the 4th image how you want it to end up or a result of your configuration? If all you need to do is change - to /, just stick a Repl…

@arb sorry, it’s not your fault — my native language is Spanish and my English is basically zero. I communicate with you through translators, and of course the image gets translated too, so I can’t tell what is correctly or incorrectly written. I’m going to edit the post so it’s easier to understand…
