Traktor Kontrol S4 - Using 4 FX Units
In the Traktor Pro S4 default configuration only two of the four available FX units are used. In this setting the eight deck/FX assignment buttons on the S4 controller can be used to assign FX unit 1 and FX unit 2 to each of the four decks.
Things change a bit when you enable all four FX units in the Preferences/Effects dialog box. Then, four of the assignment buttons are disabled. The other four can be used to enable/disable the pre-defined assignment between FX unit and deck. Each deck then has its
own dedicated FX unit: deck A uses FX unit 1, deck B uses FX unit 2 and so on. The new assignment is shown in the following picture:
In a way this restriction makes sense if S4 is the only controller you use. You have one dedicated FX unit for each deck. The effect parameters for FX unit 1 and FX unit 2 respectively can be controlled by the corresponding FX section on the controller if the focus switch button on the controller is set to deck A and deck B. If you switch the focus to deck C and deck D the FX sections on the controller allow you to change the effect parameters for FX unit 3 and 4.
It would have been even better if Traktor could remove those FX/deck assignments that can no
longer be changed anymore in the default mapping after you switch to 4 FX units mode. Let's assume you
have assigned deck A to FX unit 2, then the assignment is still active after enabling 4 FX unit mode. The simplest way to remove the assignment is using the buttons in the Traktor GUI.
The manual states about using four FX units: With the four FX Units 1-4 activated, channels are differently routed to the FX Units. […]This routing cannot be changed, only activated/deactivated.
This information is wrong: The routing, here the assignment between decks and FX units can still be changed. The only thing that cannot be changed is the embedded mapping that restricts the deck/FX assignment in the way described above.
Getting all Deck/FX assignments back
If you use another controller next to the S4 it can still be useful to be able to assign FX unit 1 and FX unit 2 to all four decks. To achieve this I created a small user mapping for the S4. It overwrites the restrictive default assignment in 4 FX units mode and re-enables the four disabled assignment buttons. You can download the mapping here:
Pro S4: User Mapping to reset FX/Deck assignment in 4 FX mode
This mapping can best be used together with my S4 mapping for Traktor Kontrol X1. This mapping
- allows you to control the effect parameters for FX units 3 and 4
- gives you direct control of the volume and filter knob for each individual sample slot
- gives access to Hotcues 5-8 of deck A and deck B
