Can you provide information about DJS trial and how do we use this for a Pioneer CDJ 400 through a USB cable to laptop to play music?
The application is available for downloading as DEMO version from its official website. I have installed it and it's working normal, only that you need to access the Preferences menu from File(F). Go to the DJ Play > Mixer/SoundCard. Select the sound card where the device is connected and then you can use it accordingly.
