Before doing any troubleshooting it is a good idea to check the tag writing settings in MIK which can be found in the Personalize/Update Tags tab.
Once files have been analyzed by MIK, you have to tell your other software to read the file tags again. Instructions for doing this in most popular DJ apps can be found in the Personalize/Connect with DJ Software tab in Mixed In Key. If you've followed these instructions, and still don't see your keys for some or all of your files:
- Check to see what file format your audio files are - only certain file types can be tagged and read in your DJ software, the most commonly file types that have full tagging support are MP3, MP4/M4A/AAC, FLAC, and AIFF. WAV files are not tagged by MIK because they do not contain ID3 tags and metadata support for them is so poor.
- It could simply be a glitch that the tags weren't written correctly the first time. You should select the files in MIK's browser, right click on the selection, and choose to retag the files. Once the files have been retagged follow the procedure for refreshing the tags in your DJ software again.
- If you had file renaming turned on in MIK, you won't be able to refresh the tags in your music library software. When MIK renames the files, your library software will have the incorrect file name, and the files will need to be reimported or the filenames changed back to their original state. To correct this please select all of the files in MIK's Browse Collection panel, right click on the selection, and choose "Remove Keys from Filename." You should also turn off the file renaming option to prevent this from happening again.
- If you are using iTunes: When you go to refresh the tags by updating the metadata in iTunes' Get Info window, DO NOT update the comments. If you did you just erased the tags that MIK wrote. To refresh the tags in iTunes you need to be updating one of the metadata fields THAT YOU DO NOT PLAN ON USING.
Go to iTunes Preferences -> Advanced tab and uncheck the "Keep iTunes Media folder organized" option. This setting is misleading because iTunes will still sort your files into Artist/Album folders with it turned off, but if you have it turned on you're giving iTunes the ability to automatically rename files and make changes to the metadata in your files.
In the same tab you will see an option to copy files to iTunes Media folder. This feature can be turned on or off but you need to be aware of which setting you are using. If you have this turned on, you need to be analyzing the files from iTunes Media folder, not the files in your Downloads folder. You can drag and drop files from iTunes and most DJ apps directly into MIK, which is my preferred method of adding files because it helps to avoid this problem.
- The files might be stored in a folder that is read only, or the files themselves might be set to read only. Right click one of the files that isn't updating in your DJ software and check to make sure that read&write permissions are enabled. Another easy way to test this is to drag a file onto your desktop and analyze it from there, then add it back to your DJ software. If it then works, the problem lies in the folder containing your music files.
- If you are using Traktor, note that the 'check consistency' menu option is only found if you are browsing files in Traktor's collections. If you are looking at the files in the iTunes playlists in Traktor or Serato software products, the files need to be updated first in iTunes. Note that the key will not show in the Key column if you are browsing iTunes playlists in Traktor or Serato because iTunes does not have a Key field. You have to use the comments field or import the files into Traktor or Serato collections if you want to use the Key column in those programs.
- If you are using newer versions of Traktor 2, the keys written by MIK to the INITIALKEY field will show in Traktor's "Key Text" column. If you do not see this column, you can add it to the browser by right clicking on the browser headers and selecting it. To avoid having Traktor overwrite our keys, when files are analyzed in Traktor check everything but Key in the analysis options pop-up that shows before Traktor analyzes files.
- If you are using Serato and .m4a (AAC or ALAC) or .mp4 files and you don't see the key in the Key field of Serato you probably need to update your Serato software. MP4 files don't contain a standard InitialKey tag, so the industry has adopted a custom tag. Older versions of Serato (think 2011) did not support this custom tag.
- The ID3 tags may be in a strange format that is causing them to be incompatible. Stripping and converting the ID3 tags can often fix this type of problem, but we would much prefer to fix the incompatibility by making an adjustment to our tag writing code. Make a backup of a few files before performing this procedure, and if it works send the backup files to us by following the instructions in the next step. Instructions for the strip and convert can be found in Tip #3 here.
- If you've checked the above troubleshooting guide and still don't see the keys in your DJ software, please upload one of the files that you have analyzed but isn't showing its key to speedyshare.com, send the download link to [email protected] and we will take a look at it. Also, please include a brief description with the file so that we will know what the file is in regards to. The more information you can provide the better the chance of finding a quick solution. Things like where you had MIK write the key, what software you are trying to view the key results in, what operating system you are using, and what version the software is are all helpful.
