Key Signature writing into ID tags of songs?

Is there a way to write the song keys into the ID tags so the key is recognized in other programs such as serato, tracktor, etc. I am using serato itch with numark ns7fx and would love to not have to manually insert the keys into the song. especially with for the 12,000 songs I just added to my library.

Hi Mitch,

Sorry, we’re not familiar with the other apps’ data structure. But generally speaking, djay stores its data under this folder: /Music/djay/

You could write an Applescript that reads djay’s data and stores/exports it.
