Hello everyone! I hope someone give me a help...how can i record the ZERO 4 master output on the Deck D of traktor in external mode without external sound card but using the internal mixer's sound card...?

with this set: http://imageshack.us/a/img10/6964/7k3v.png

and this: http://imageshack.us/a/img196/1064/dhmm.png

I record with ( 9: zero4 in 8 and 10: zero4 in 9) but only if I have activated the sampler and FX on all 4 channels...

If I want to use this effect: http://imageshack.us/a/img854/311/p4o9.png only on the channel 2 (for example) the other channels that I have unchecked are not recorded...

I try also to change all the channel on zero edit master and the traktor imput but nothing... can anyone help me?
