SoundSwitch Supports Virtual DJ 2018 using the Open Sound 2 Light (OS2L) Protocol
This video explains how to setup SoundSwitch with Virtual DJ.
Virtual DJ Folders.
At present, SoundSwitch only supports Virtual Folder in VDJ and does not support Favourites Folders or Filter Folders.
If you have set up your Virtual DJ library to use Favorites Folders, you will need to create Virtual Folders for each Favorite Folder and move the tracks from each Favorite Folder to the new Virtual Folders.
