now that the rane mixers have asio drivers you can pretty much count on the fact that its likely the best soundcard/mixer combo money can buy.
same with the new allen and heath mixer. im hoping to god a&h releases drivers for the xone:dx as well. the soundcard on that thing is a beast as well.
You can only get the timecode features of Traktor scratch pro with a Traktor Certified mixer. you can use most soundcards, but not for timecode control.
Well you can’t buy a scratch licence without the harware so that shouldn’t be a problem, just plug your Audio 4 or 8 or TA 6 or 10 into whichever mixer you like.
The 92 is one of the best mixers so I think you should keep it. I have a 4d and the sound card is great and is certified to use with scratch pro and sounds amazing as well. Either the denon 1600 is certified and the mackie d.2 and d.4 IMO those are the best combos sound card-mixer. At least the xone will sound equally good to the NI sound cards. The xone card is 10 in and 10 out so will be very similar to ta-10 and has thru option as well.
