NI Audio 8 Interface w/ Ableton Live
my friend wants to purchase traktor scratch pro, and is curious if the audio 8 dj interface would work with ableton live as well?? for dj purposes 
yes it will work.
I use the NI A8DJ for Live and it works just fine.
I will be using the Audio4DJ with Ableton shortly, but I am guessing it will work just fine.
