Request for Traktor Pro 4 Features - Multi core and multi stem separation

em5

Creating or recreating thousands of stems takes hours of right clicking on every track (well plus days of processing). Traktor Pro 4 is a great step foreword, and now is the time to add that stem generation option to the right click menu. This must be easy to implement. We would also like a few added lines of code to stem separate more than two(?) tracks at once for way more speed. Currently stem generation uses 2, maybe 3 or so cores and makes the playback stutter, with 30% or so total CPU utilization. Maybe a setting under "Multi-core Processing" of how many threads to create for parallell track analysis, stems and so on. If that's to much, you could comfortably assume most people have at least 8 cores, as creating a few more threads than there are physical cores makes no practical difference since there will be enough logical cores to carry them anyway.

Thanks in advance!

I agree!! it runs the same issue here, my 16 cores cpu usage is low, but the Traktor just… struggle!

I just noticed that if outputting audio on a PCI sound card (Yes really, PCI, Audigy 2 ZS), the audio DOESN'T stutter when generating stems. The graphs stutter as they always do though (ChatGPT suggested changing to NVIDIA studio drivers, tweaking its settings, disabling all sorts of stuff, 100% DPI, even running it in windows 7 comparability mode - Nothing touches the ~15 FPS). Something interesting is that when generating stems nvlddmkm.sys (NVIDIA driver) is spiking hard: DPC routine execution time: 1274 µs (😬 way over the safe zone)dxgkrnl.sys (DirectX graphics kernel) also high at 543 µs. Its not like RTX2080S can't draw a 2D graph (its the same on my laptop with intel iris XE, and my super old ****** emergency backup laptop)

Is the bottle neck in Traktor its graphic rendering?
