@winkar > First, you don't need to use the aggregator with SSL. Because the output audio device for SSL is the SL box itself, it doesn't even use the CDJs as audio devices. I would check to see that you have both of your CDJs set to ADVANCED HID mode (under the utility menu on the CDJ). You should have each deck connected before you load SSL and then the display will show "DECK: A?" and you can then select the other decks on each of the players.
Don't worry about the translation, there's a Google translator over there you can use! ---->
