Real Time Stems - Traktor 4

Rajiv Cassie

As grateful as I am that we have stem separation now. Will we ever see real time stems being implemented in to Traktor?

I understand that for most house or techno DJ's that real time isn't a huge factor.

But, for open format club DJ's, it would really be beneficial.

I can fully understand your point of view as an open format dj. but as you know, preparation is also a honorable way and will not affect you that much in creativity on the fly.

I found this quote today on djtechtools:

Traktor Pro 4 features stem separation powered by AI, and iZotope’s powerful RX technology. We can’t share too many technical details, but we have the same upgraded machine learning as the new RX 11, which is based on the most modern neural network available, plus our own pre and post-processing to further increase the quality of separation. For Traktor, we’ve decided to prioritize quality over speed and have chosen settings that work well across all genres. For now we are not exposing these settings to keep it simple and consistent across the entire collection.

The current implementation is CPU-based, and optimized for CPU-processing (as opposed to GPU). In a future update we could expose more parameters to give users more control over the speed and quality tradeoff, but we’re waiting for more feedback on the feature as it ships in Traktor Pro 4.0.

Maybe we'll see "real-time" stems in a future update.

In addition to what Owner said (great quote, by the way), I think that maybe fully harnessing machine-learning resources beyond the CPU, like, say, Nvidia GPU chips or in Apple's case the built-in machine-learning Neural chip inside Apple Silicon (M1, M2, M3) will come in a future 4.x release.

Indeed, perhaps a "let's deliver this feature now, instead of later when we can program those chips" perspective could've been part of the internal discussions in the development team. Just making a wild guess here, based on what Owner quoted.
