One additional tip to Terry’s extensive workflow description:
You can select what info you want to copy to your memory stick and which order you want the CDJs to display search criteria. Also you can specify the settings for the CDJs. So when you put in your USB stick it will say it has found config file do you want to load it. Confirm and it’s set to your personal preference.
So, while you are patiently waiting for the automatic analyzing to take place, be sure to read the manual on those options and make sure you understand what they do. That way you can tune RekordBox to do what you want.
Good luck and greetinx.
