hello i'm using the traktor program for mixing and when i analyse my mp3 songs to it i can see the sound key for every one of it. now if i use (example) the mixmeister bpm analyzer and then i trag the song in to mp3 tag folder and push the save option. i will automatic see in my windows folder the bpm that mixmeister taged in to my song. can i do the same thing with the sound key? and if not how else can i do it without taking one by one the mp3 tracks seperate....

thanks!

I doubt that you can do it with MP3tag.  
To find the BPMs you have to use an external application that interprets the audio-part of a file.  
Mp3tag does not edit or manipulate the audio part. It edits the heading or trailing tags.

Does your traktor program store the "keys" in a field (I cannot see a field that looks a place to store that information)? Or does it determine that information at runtime?  
I do not know a program that also supplies this information for a batch job.

Traktor reads the Key Information from a tag called INITIALKEY.

You can setup MP3Tag to show a custom input field for this tag on the left hand side. Check the config options for the "Tag Panel" in the Preferences to set this up.
