Notes
By default the mixer of the 4 TRAK will follow the 3-1-2-4 Mixer Channel order. A different mixer order can be applied either from the Mixer Options menu (right above the Crossfader in the 4 decks default skin) or from VirtualDJ settings (MixerOrder setting in OPTIONS)
The 4TRAK is a stand-alone mixer and can operate without any software running on computer
