Kontol S4 can't control volume

Kontrol S4 mk2 just stopped having the ability to control the master volume in Traktor scratch pro 2.

I think it was after an update..but now I cannot get it to re-link to the action. I have never had success assigning control to specific knobs on the Kontrol via control editor.... so can anyone please give me a helping post???

thanks

Can you be more specific? A.k.a. does it control any volume when you turn the knob either way? The S4 controls HID volume. Any other type of controller would be "super midi" command script in a given .tsi file

Sidenote:The generic mapping includes the command and should work natively.

Try deleting the default mapping, disconnecting the S4 and then reconnecting it. Tractor should automatically recognize and load that remapping/controller settings. Keyword being should. Not sitting in front of your computer so it's hard to tell .

Hope this somewhat helps. If not there's always more troubleshooting we can attempt
