I use Traktor Kontrol S4 mixer and Traktor Pro 4 software. I'm having a problem with deck volume faders possibly due to the settings that must be adjusted. When I bring the deck volume fader down on my mixer it does the same on the software screen which is fine. But when I load track to a deck, the fader on the screen jumps up to full volume while my volume fader on the mixer is still down. Please advise how to make the software follow the unit. Please be more detailed. Thanks in advance for your help.
