I have a feeling my Kontrol S4 Mk2 requires it's jog wheels calibrated, since the left jog wheel no longer registers press/touches on top (which would normally stop a playing track). The right one seems to be intermittent, but only occasionally registering touch.
I've attempted to re-calibrate in Traktor by going to Preferences -> S4Mk2 -> Recalibrate Left/Right. It then asks "Press and hold its corresponding 'Load' button for 2 seconds".
For both jog wheels I cannot get past this step. Nothing seems to happen no matter how long I hold the "load" button for either side of the controller.
I have also tried to reset Traktor by moving Traktor Settings.tsi to the desktop to no avail. Device Updater 1.7.0 says my device is up to date (version 69). I've tried different USB cables and even a whole different computer.
I have also tried to calibrate with Controller Editor, by going to Preferences -> Kontrol S4 MK2 has no option for jog wheel calibration like is explained in the calibration guide: https://support.native-instruments.com/hc/en-us/article_attachments/205618865/Jog_Wheel_Calibration_Guide_English.pdf (I would assume the guide is written with Mk1 in mind?)
I had a strange thought - perhaps the new version of the software is no longer able to calibrate older controllers due to some software regression? I had the thought to run the older version of Traktor 2 on my Mac from a date closer to the release of the S4Mk2, however I am unable to install these older versions without an error "No previous installation found".
