I need something that can do the same as the MixedInKey program (Add info for the key of a song in my traktor menu)
All of my mp3s have blank information for the KEY of the song and i need something that can do this, but i can not afford to pay for one at the moment.
This program is called rapid evolution. Its not as glamorous to look at as mixed in key, but it is free and it does everything you need it too. I use rapid evolution 3 on a Lenovo laptop running Windows 7 and have not had any issues running it while traktor is running.
