How to set up Audio Interfave with Kontrol s2 mk3

Hello,

why do you use 2 interfaces? Just setup one (with the asio driver if you use the komplete audio) and just use this. But if you set it up like that you need to setup the S2 as interface and the audio 2 mix knob to input. Headphones then of course connected to the s2

Yeah I saw in the manual that the direct monitor only works for the headphone output. So then it's not possible without software that routes the inputs to the outputs on the back of the audio 2 but this will add a delay but possible. So best is to only use the interface of the controller or buy an audio 6 and use this at home. If you don't want to plug and unplug the cables to the device you could use extensions too.

Here native also describes that you need a DAW to route input to the outputs on the back: https://support.native-instruments.com/hc/en-us/articles/4409573433361-Using-the-Direct-Monitoring-Feature-on-My-Komplete-Audio-Interface
