In reply to
me how I have plug/map the mixer with the soundcard/ableton please

I'll overlook your use of that smiley

You need to be clear on how you are recording your set. Are you recording it in Ableton itself? If so, why? Surely if you are, you are not picking up audio from your CDJ's. Anyway, in which case, you will not be able to send the DJM effects into Ableton, you can only record those effects from the external out from that DJM mixer. You will have to output your REC OUT from the DJM into your Line In on PC/Soundcard and use another application, for example Soundforge or Audacity, select the recording source as Soundcard Line In and then set it to record. This is the only way to pick up all 4 audio channels and utilise the effects of the DJM.
