Stream Rekordbox to OBS without soundflower

You need to have RCA's from your controller connected to Line In of Mac.

Then choose Audio Input Capture from Sources of OBS,
then from Device dropdown menu select Built-in Input (Line In).

If connections and settings are correct you will see the sound level meter in green.

No you don't...

I have a guide on this coming soon.

Pulse - have you done the guide yet?

Bits on the cutting-room floor, waiting for some approval from Japan. ;)

Looking forward to the guide! 

How we getting on with this guide Pulse?

And will OBS be able to display the current track from the CDJs (like master deck song)?

I've seen people streaming online using Pioneer CDJs and XDJ-RX and get the track titles automatically show, some even have fancy background images as well.
I'd like to do this also.

Is this DOA? Serato lets you send straight to OBS using iShowU without fiddling with mixlr / Soundcloud settings. Seems like a pretty clear win for Covid times.
