I have a S2 MK3 but I want to buy these controllers for using better the effects but also I want a more mobile setting with the X1 and Z1, but also would like to know if I can use the three together to have a 4 channel controller
Normally the Z1 will control your Decks A and B. So you might need to remap controls on the Z1 to be able to assign C and D mixer section.
If you need help with that, let us know.
Can you connect traktor s2mk3 with the combo z1+x1mk2 to mix on 4 decks? I need help for this
Like Stevan said. You would need to remap every control on the z1 from AB to CD.
The x1 is easy. It asks you what you want to control on startup.
Discovered this in the mid time... By default, the Z1 will disable monitoring on Decks C and D. It can be mapped but pre listen on Decks C and D won't work if Z1 is connected.
