What do you recommend? Kontrol f1 or x1

The F1 is a very good controller, but mostly dedicated to Remix Decks. They expands Traktor functionalities, allowing to easily add loops and one shots to the normal Track decks.

The controller you already own (S2) is already capable of controlling them, but having less pads limit a little bit this function (you have to switch “pages” to control the same amount as F1.

The F1 is also “moddable” and can like this also become a valid step sequencer for the sounds loaded in a Remix deck

Also the Stems Decks can be controlled with the F1 (but, once again, also the S2 has some control on them)

Kontrol X1 seems a little bit redundant to me if you already own a S2, but YMMV

Summing things up: with the S2 you already have some controls on every Traktor aspect. The F1 will surely add a lot, with better control on things like Remix Decks, Stems Decks and eventually Sequencer. The X1 having a S2 would be a no for me

Todo lo que necesitas saber en español:

Resumiendo: con el S2 ya tienes algunos controles en todos los aspectos de Traktor. El F1 seguramente agregará mucho, con un mejor control en cosas como Remix Decks, Stems Decks y eventualmente Sequencer. El X1 teniendo un S2 sería un no para mi. Bastante mejor dos Kontrol F1 para controlar dos Remix Decks 😉
