No, the default location is:
~/Users/yourusername/Library/Pioneer/rekordbox
Or for the full path,
/yourharddrivename/Users/yourusername/Library/Pioneer/rekordbox
If you are using the database externally, then it would mount differently, and rekordbox can be told to look in that location, but as you're doing something a bit custom, you may need to edit the settings file. See my article on cloud database storage here.
