Mixer

The mixer part of the PIONEER DDJ-SZ is a hardware mixer and the audio routing is done internally. Every button, knob and slider is MIDI capable, however only some of them are assigned with VirtualDJ script actions, therefore some parts will not be visible moving on the GUI of VirtualDJ.
Note that even some parts control the GUI of VirtualDJ, those do not alter the internal software mixer. It is strongly advised not to assign any VirtualDJ script action (other than the default ones) to any other part of the mixer.
