Aggregate Device - DDJ SR & Traktor Audio 6 DJ with Rekordbox DVS

Hi,

I'm wondering if what I'm trying to do is possible, basically what I'm trying to do is use my DDJ SR and traktor audio 6 dj soundcard for DVS functionality. Although the traktor sound card is not certified or supported by Pioneer, I have been able to use it with Rekordbox DVS, my issue is that the DDj SR is not an external mixer so what I'm hoping to do is merge the 2 sound cards as an aggregate device on my mac so that I can use the DDJ as my output and the audio 6 for dvs but I can't seem to get it to work.

I've seen other posts where people have managed to do the equivalent with a DDJ T1 and sound card with traktor so I'd imagine it would be something similar with the DDJ SR and Rekordbox Dj

When I chose the audio 6 as my primary sound card, I can get the DVS to work and the DDJ functions also but only for controlling RB but and not as an output device i.e. I can't cue any tracks etc as the sound is being outputted from my audio 6 instead.

When I chose the aggregate device, I can't seem to get any DVS functionality whatsoever.

Any information would be a great help.

Thanks
