Since updating to the new osx when closing traktor the s4 won’t turn it self off and numerous lights stay lit after closing the program is there a setting which controls this to turn it off other than than the power button on the s4.
Even if you close Traktor and shut down the computer, the S4 is still on untill you hit the power button on the back. Wether more lights are on or not is irrelevant. Normal S4 behavior would have the USB symbol above Master lit while the unit is plugged in and turned on, but Traktor isn’t open. No lights when off (using the power button) of course.
Why mavericks has changed the lights behavior after shutting down Traktor, I couldn’t say, but it doesn’t really matter as long as everything works fine while using Traktor.
