Using a seperate mic. to broadcast via Traktor, together with my Z1

Hello out there !

Im going to Dj on a radio live broadcast. To do shoutouts, i need a microphone. I got a second Headset (Turtle beach - USB Headset), which i want to use as a mic. on Deck C in Traktor, while using my Z1 and X1 together as usual on Deck A and Deck B. (My Heaphones for mixing are connected to the Z1)

The problem is i only can choose my Turtle beach OR the Z1 as an audio device.

How can i fix this ?

Thanks in advance !

 

I did exactly the same as you recently:
You need to create an aggregate device in your computer audio settings. NI have a few help pages on this.

It might help for you to do some device mapping.
I did it to use a fader from the Z1 to control the fader on deck C. When MODE button is lit i can control faders C and D when not lit A and B... (needs to be "soft takeover")
