I'd like to show the Key a track is in as COVERART.
The key is analyzed by Mixed In Key which writes into the COMMENT-tag and INITIALKEY-tag of a MP3-file.
Traktor collection (Green lined is desired outcome):
Something like:
If INITIALKEY is equal to 1A, then embed C:\pictures\CoverArt-Key-1a.jpg
If INITIALKEY is not equal to 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 1B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, 9B, 10B, 11B, 12B, then embed C:\pictures\CoverArt-Key-None.jpg
The action of the type "Import cover from file" allows you to enter a format string.
So you can enter more or less any combination of text constants and variables as you like to create a filename for the cover file.
E.g.
Format string: C:\pictures\CoverArt-Key-%initialkey%.jpg
should create a filename as you described it.
I don't want to create a filename for the cover file, I want the already excisting pictures, to be embedded in the mp3-files.
Which one to embed, depends on the INITIALKEY-value of that mp3.
In the action "Import cover from file" you need to create a filename to address the file you want to embed.
I made a suggestion for the combination of text constants and variables which also includes the initialkey value.
