@Cristian > If you are setting an 8-bar loop (32 beats), you need to ensure that you have the 32 beat loop length selected:
Once it is active, you'll see this:
If your beat grid on the track / the analysed BPM are inaccurate, showing double what it should be, then a 32 beat loop would play only 16 beats of audio.
Please check that these are correct and if you're still having a problem, please record a video showing the loop settings as you activate them.
Regarding Traktor, Pioneer provides a base mapping for 2.6.8, but you are welcome to customize or modify the map as you desire. What is it that doesn't work as expected?
