I'm using Traktor Pro 3 on Mac High Sierra with Audio 2 mk2, Kontrol X1 mk2 and a pair of CDJ-350's which all play via a 4 channel DJ Mixer.
I have Traktor set up as 4 decks. Audio 2 controls decks A and B, the CDJ's control C and D
Whenever I open Traktor and load a tack into decks A and B, I have to adjust the Audio 2 because deck A will not play any sound via the mixer (the deck in Traktor works as normal, display moves, etc) and deck B will play out of 2 channels on the mixer at the same time.
I have to adjust the Audio 2 left volume (which is the 'main' volume) up which makes deck A play on one channel and deck B play on one channel.
Why do I have to do this every time, I never used to. The only things that have changed since are, I've moved house 🤷♂️ and fitted a different USB PCI.
I know this is a first world problem and going to sound whiney but it's really annoying to have to do this every time due to how my setup is 😅
Updating Traktor has not resolved the issue either.
Thanks
