Implement on-the-fly live stems separation technology in Traktor would be a killer feature.
It's a pity Algorithm or Atomix already did that whereas the stems concept was developed by NI.
NI's got the best DJing hardware on the market for that purpose.
With izotope technology, and the fact that computers nowadays have lots of processing power (such has the Apple M1 Pro or later), should make it possible to implement the feature.
