iTunes is incapable of showing keys.
For Traktor to show the keys, you have to make sure beaTunes embeds the data into your files.
It will only do so, if you check the box "embed non-iTunes data into file" in the beaTunes general preferences *before* you run the analysis.
And still no key tag is added to my song, not in the "key"field
in beatunes, neither in the comments on itunes. Dont get it, is
very frustrating. I use the program on windows, and the screens in
my beatunes like this earlier links are little bit different, but
the options are the same, only the option analyze key i dont see.
But the option replace exisiting key is availlable in the analyze
window. These are the steps i follow:
Open Beatunes (and itunes will also open)
Selected the option embed non-iTunes data into file
i select the option replace the excisting key
Analyze and nothing changes to my song, no comment no key in te
key field in beatunes, dont get it.
