Reply to S4 Killswitch Equalizer

Hey there,

sorry for such a beginners question first
I just recently got my Traktor Kontrol S4 and as far as I know there is no build in killswitch for the equalizer.

Ist there a method to map this somewhere on the S4?
Or is this not possible without an external controler or the the X1 for example?

Thanks for answers

Greetings !
