I contacted the support few months ago because I could not tag my AAC files. The key information shows up in mixed in key but when I import the files in rekordbox, the key won't show up in the key field... Thus, I have to use the comment field to tag my tracks which is not convenient at all for me because I used to use the comment field for other purpose. Tagging was working fine in previous versions of mixed in key...
Is there any chance to see an update coming soon because when you pay a certain price for a software but you can't use it fully, it's a little bit annoying :)
Thanks a lot !
This is an issue we've been having with the most recent versions of Rekordbox. It's definitely something on our To-Do list of things to fix on the next Mixed In Key update. It seems to work fine with MP3 files. The issue happens with WAV and AAC files.
We will let you know as soon as we get a fix for it.
