Field Mappings
Lexicon supports more fields than all DJ apps do (Energy, Danceability, Popularity field but also your Custom Tags) which can be mapped to normal fields using the Field Mapper.
You can set up different field mappings for each DJ app you sync to and for writing tags directly to your music files. You can also use field mappings when writing your file (ID3) tags.
Editing Field Mappings
In the Sync window (open it with Sync to DJ app at the bottom of the sidebar) or in the Write Tags popup, use the Edit field mappings button to set up your field mappings.
A mapping has a source and a target. The source is a field from Lexicon and the target is a field that exists in the DJ app.
For example, all DJ apps have the Comment field that you can map to, but only VirtualDJ has the User1 and User2 fields.
Choosing a mapping Energy ➡ Comment will result in your DJ app Comment fields to look like "08 Energy". Energy, Danceability, Popularity and Happiness are always written as a two digit number followed by the field name, so they sort correctly. This format can't be changed.
When you import from that DJ app later, Lexicon reads these values back into Energy, Danceability, Popularity and Happiness and removes them from the field again, so they don't pile up with every sync.
Which fields can be mapped
The source list only shows Lexicon fields that the DJ app doesn't already have. Fields that the DJ app supports natively (see the table below) are synced directly, so they are not in the list. For example, Rating can't be mapped for Rekordbox because Rekordbox already has a rating.
Always available: Energy, Danceability, Popularity, Happiness, Extra 1, Extra 2, All Custom Tags and each of your tag categories (Tag Category: ...). Depending on where you sync to, these are available too:
| Target | Extra source fields |
|---|---|
| Rekordbox 6/7 | Grouping, Producer, Last Played |
| Rekordbox 5 | Grouping, Lyricist, Producer, Last Played |
| Pioneer USB | Grouping, Producer, Last Played |
| Serato | Lyricist, Mix, Producer, Rating |
| Traktor | Grouping, Lyricist |
| Engine DJ | Bitrate, Color, Grouping, Label, Last Played, Lyricist, Mix, Play Count |
| VirtualDJ | Lyricist, Producer |
| Djay | Last Played, Lyricist, Mix, Producer, Remixer |
| iTunes | Color, Grouping, Label, Lyricist, Mix, Play Count, Producer, Remixer |
| File tags (Write Tags) | Color, Last Played, Mix, Play Count, Producer, Rating |
If you want a field that is not in the list somewhere else, first copy it into Extra 1 or Extra 2 with the Copy field recipe (see Recipes), then map Extra 1 or Extra 2.
Overwrite
When you enable the Overwrite checkbox, Lexicon will overwrite the field with the new mapped value in the resulting track. If you disable overwriting, then the new mapped value will be appended to the original value.
Combining
You can choose to combine fields by mapping different sources to the same target. The results will be separated by a comma.
For example: Mapping both Energy and Popularity to Comment will result in "08 Energy, 05 Popularity".
You can combine as many fields as are available.
Engine DJ Color
Engine DJ does not (yet) support track colors. To get your colors from Lexicon in Engine DJ, you can create a field mapping. This will add the color name in the chosen target field. For example, the color Dark Red will be turned into "Red_Dark".
Custom Tags
The format of mapped custom tags is set in the Lexicon settings (General) with Field mapping Custom Tag format:
Hashtag, for example#Techno #VocalsComma, for exampleTechno, VocalsSemicolon, for exampleTechno;Vocals
See the Custom Tags manual page for information on how custom tags are handled.
