I just got the Hercules Universal DJ.
These are the “features”
1 - Plain usb controller deck
2 - Usb controller deck with bluetooth “multi screen”
3 - Bluetooth only controller
3 is bad, you need the djuced app, and it seems it doesn’t really work on samsung tablets. The audio comes from the tablet. The djuced android app is not capable of using the usb input.
I tried 1+2:
In mode 1 the controller is a pure MIDI (2 midi in, 2 midi out, I have no idea what the midi out does), a 4 channel output with gain control per 2 channels (“mix out” and headphones out), a 2 channel input without any controls.
In mode 2 the controller stays the same. On your phone/tablet you need to install DJuced Master, and pair your phone with the deck.
The phone/tablet adds a number of extra controls, that is mapped to midi. The DJuced Master app has some more features that somehow interact with the DJuced 40 pc app. I have no idea how to run that.
I got the idea that the deck is slightly over usb spec, as my system that is able to power harddisks, kept in a device resetting loop. Plugging it into a powered USB hub fixed this problem.
anyway… on to the mapping.
