There is no reaction when you press the first (left-most or top-most) button on an FX section of your TRAKTOR KONTROL controller (e.g. TRAKTOR KONTROL S8 / S4 / X1)
The FX Unit is set to Group mode. In Group mode, there are only three control buttons, each switching an individual effect on and off. The left-most button has no function, as indicated by its absence in the software interface.
Note: If you do not see the FX Unit in the TRAKTOR software, you can enable the option Show Global Section in the TRAKTOR Preferences > Global Settings.
Set the FX Unit to Single mode. IN Single mode, the left-most button (ON) switches the effect on and off while the other three buttons / knobs control individual parameters of the effect.
You can switch between Single and Group mode by doing any of the following:
- Click on the number of the FX Unit
and select Single or Group from the drop-down menu.
- Select Single or Group under FX Panel Mode in TRAKTOR Preferences > Effects.
- Switch between Single or Group directly from your TRAKTOR KONTROL controller. Please consult your controller's user manual to learn how to toggle between FX Panel modes.
