Live Streaming with DJM 750k and OBS + Windows via USB

Hi there!

I'm just wondering if anyone has had any success live streaming from a DJM 750k using windows + OBS via USB

I've tried using this guide: https://forums.pioneerdj.com/hc/en-us/articles/115004806423

But I stumbled on the step in Rekordbox 'Click External for the Mixer Mode, and scroll down to configure the Output Channels'

There appears to be no option to change the 'Mixer Mode'

Also a few steps later within Voicemeeter Banana, when selecting the A2 output assignment - I have no option to select 'WDM: CABLE Input (VB-Audio Virtual Cable)'

Am I doing something wrong or is the 750k not compatable?

Please help :D
