I am doing stems mixing and the effects on the x1's don't work. What am I missing? I have watched the videos by NI and they don't help. I am relatively new to Traktor and invested in the gear in order to really explore stems. But am getting very frustrated with the effects not working. From other threads I have read it seems that this might be an incompatibility with the x1 and stems? Is there a way to connect all the units that would fix this? I also have an S4 mk3 but I am hoping that I can retire it and go forward with the modular units.
