Recording / Live Streaming on DJM 450

Hi,

I'm looking to get into live streaming with OBS software while using the following setup

1 x djm 450

2 x cdj 1000s w/ timecode cds and Rekordbox DVS

My issue is when I set the audio device in OBS to my DJM 450, when I record, it picks up both the track playing in Rekordbox DJ as well as the timecode sound. Is there any way around this?

When I go into the DJM 450 utility setup, obviously if I change all the channels to REC OUT, then everything works fine but I lose DVS compatibility which is no good to me! I'm hoping that I don't need to go down the route of buying a second soundcard and route the master out to the second soundcard!

Any info would be a great help!

Thanks
