Nuo Stems 4 Upgrade is 💯 worth it 🚀. EXTREMELY much better results than Nuo Stems 3. Results are so much better than stems generated by Traktor Pro, VDJ, Djay Pro, Rekordbox and Serato.

It does take quite a while to process the files, but I love the results. The Traktor integration is so fire. It's an awesome app!

Incredible work man!

NS4 stems sound awesome and the linked files are great!

NS4's ability to queue up my 5k tracks, saved me a billion of clicks in Traktor, while still getting full integration with linked stems in Traktor

I love it. I have a mixed bag of traktor s8 and pioneer rekordbox of flx10. It's flawless on Traktor. Cheers mate and keep up the great software!

I've used it and it is better at separating the stems than all the other DJ softwares.
Tore Douglas
Separation Quality is MUCH better, much more decisive on 'what sounds go to which stem' with little artifacts. Around Drops it's very clear Nuo Stems 4 has improved A LOT, to the point that the stems have pretty much no more disturbing 'drop artifacts'.

This is awesome—I’ve been manually replacing Traktor generated stems with Nuo-Stems versions, and it has been working great, but this will remove a lot of faffing around! p.s. I absolutely LOVE that you can generate ALAC lossless stems that sit inside the native Traktor M4A container, that link seamlessly with a lossless file in Traktor. That is very awesome.
