When the track is paused, the jog mode is Vinyl. CDJ-2000nxs: the ring on the VFD display goes off immediately, as my hand stops touching the jog, despite the fact that the jog is still spinning. The track returns to the CUE point. XDJ-RX2: even after my hand no longer touches, the touch_enable ring continues to glow and the track plays until the rotation speed of the jog drops below a certain threshold. It is necessary to increase the value of this speed threshold.

The CDJ's use a pressure switch to detect the jog action, whereas the XDJ uses a static sensor. You are correct that there is also a difference in the way the jog responds after the "touch" has stopped, but this is more to allow for actions such as a backspin. In the majority of use-cases, nobody is rotating the jog as you demonstrate after a scratch with the intention of it being a pitch-bend.

You are correct that there is also a difference in the way the jog responds after the "touch" has stopped, but this is more to allow for actions such as a backspin. - In backspin mode, when the track is playing, the CDJ and XDJ-RX2 work the same. It's good. In CDJ and XDJ, when backspin is performed, vinyl emulation (the ring on the jog lights up) continues until the rotation slows to a certain speed or stops completely, although the touch sensor was released earlier. This is the correct algorithm for behavior a jog. If the firmware took into account only the touch sensor, then backspin would be short, not realistic.
In the majority of use-cases, nobody is rotating the jog as you demonstrate after a scratch with the intention of it being a pitch-bend. - I agree, I did this to show that in the CDJ-2000nxs, in pause mode, the track returns to CUE immediately after releasing the touch sensor, even if the jog is still spinning. And in XDJ-RX2, the track returns to CUE only after the condition is met: (touch_sensor == touch_disable && jog_speed == 0 (or slow)) That is, in pause mode, the jog behaves like a backspin in play mode. But in the CDJ-2000nxs (and CDJ-800mk2 and other) in pause mode, this is not so. This difference is not in the design of the touch sensor. This is the difference in the conditions that are specified in the firmware. I would like this difference not to be. Thank!
