I connect OUT B from Behringer Digital Pro Mixer DDM4000 to Scarlett 2i/4, on Ableton -> Preferences -> Audio Input Device -> Scarlett 2i4 USB. on Audio Track I select Audio From Ext. In, but no signal arrive on 1/2, 1 or 2 (??)

  • I don't own/know the parts - therefore just general things I would check: is there some bundled software - either with the Behringer or the Focusrite - which can show you if there's any signal arriving at your computer? Did it work before and if, what did you change?

You know what, idk if the 2i4 is the right Audio Interface. I just purchased the DDM4000 yesterday and the sales person was telling me that you need at minimum the 4i4. I have the Native Instruments DJ 8 Audio Interface so I'll try to use that one, but want to connect it to Ableton as well, though really just wanted to plainly mix out of Traktor...
