DDJ FLX10 Track Separation Audio Issue

I am having the same problem. After playing with rekordbox for 30-45 minutes with track separation of one of the decks starts misbehaving. When choosing one or more stems the playback of the track is heavly distorted and not playable. Not using the stems the track sounds normal. when loading a new track the behaviour of that deck stays the same. The other deck and stems works fine. The only way to repair is restarting rekordbox. Which offcourse is not something you want to do when performing for public.

I have the same problem and I need help, I use the 3 Serato mixing platforms, virtual DJ and rekordbox and with all 3 it keeps making the annoying sounds ABC takes hours other times it does it often I don't know what to do anymore, it's like an annoying creak or a slight but annoying ground sound, I don't want that to happen in the middle of an event

Is there a solution to this issue yet? I'm having the same problem.  Thank you.

At the moment there hasn't any fixes. I can 100% confirm that changing the buffer limit does not really help and it is a software issue and not a hardware issue.

I have reported this bug and discussed it with support. I send them movies of the problem, and it is now accepted by support and under investigation like 4 weeks ago. Not heard back from them jet. Hopefully they can reproduce the problem so they can start working on a solution. And I can confirm it is a software problem, because I can reproduce the problem on different laptops and different controllers.

I have had this problem ever since I purchased the software. I've been asked to run latency monitoring and send results to Recordbox. No solution. I upgraded my laptop to 32gb, which is i7 as well. That didn't work. So I bought a new Lenovo 40gb, 4tb ssd, 15th Gen, 12 core, i7, and still the same issues, Track separation disturbs audio, & sounds like a skipping record. I do hope Recordbox will refund my money, since the product is defective

From this post I learned that the problem is coming from TS and make sense.

When I think about it, this issue occurs only when I have used track separation feature. Works fine at the start, but about hour and a half or two into my session the sound is terrible, everyone in the club are wondering what is happening and I stop everything. Then restart everything and start again.

Very embarrassing and frustrating.
