Question / Help Need help with Windows -> Rekordbox -> VoiceMeeter -> OBS Studio -> Live Streaming (Part 1)

Hi,

Here we go again!

Objective: Streaming a live set through OBS Studio, using Rekordbox and physical Pioneer hardware gear.

NOTE: I don't need (or want) any sound coming out from my laptop speakers at all. The only sound that i want to ear, is the sound coming from my external speakers (and also the headphones connected to the mixer, of course).

NOTE 2: I also had made some improvements since the last post. I now have a sound signal in VoiceMeeter Banana coming from Rekordbox. The last step is to route that signal into OBS. This thread is better structured and can be read in a simpler way.

My HARDWARE setup is:

A DJM 450 mixer connected to two CDJ's via RCA cables. All these devices are then connected to an USB Hub. This Hub is then connected to my laptop via USB. The sound is going out from the mixer, using the Master 2 output, to an external amplifier (Pioneer A-20) using RCA cables as well. Finally, the external speakers are connected to this amplifier using the usual cables for this matter.

I also have two turntables (PLX-1000) connected to the mixer's Phono inputs using RCA cables. Nevertheless, i do not intend (for now) to use these two girls on my live streaming sets, anyway.

My laptop (firmware/BIOS, drivers updated) is a pretty powerful one as i have 2 SuperRAID SSD's, parallel processing, plenty of RAM, etc. So, this guy will never be a problem.

My SOFTWARE setup is:

1) Windows 10 Pro (updated);

2) Rekordbox (updated);

3) VoiceMeeter Banana (updated);

4) OBS Studio (updated and with an ASIO driver plug-in installed, if needed in devices).

What i did achieve: i have successfully obtained a sound signal in VoiceMeeter Banana, coming from Rekordbox, using a physical mixer, two physical CDJ's, a physical amplifier and two physical speakers.

What i didn't achieve (yet): getting this sound signal from VoiceMeeter Banana to OBS Studio using exactly the same gear described above.

My setup scenario, so far:

Image 01: Available devices installed in my O.S. (right now i have those VoiceMeeter as Playback defaults).

Image 2: Available devices installed in my O.S. (right now i have those VoiceMeeter ones as Recording defaults).

Image 3: Audio driver selected in the Rekordbox (the usual DJM-450 ASIO driver that comes out-of-the-box with Rekordbox does not allow it to work with other software, as OBS Studio, does it?). In this image, you can also see the mapped INPUTS of that VoiceMeeter driver as well as i have chosen External as Mixer Mode.

Image 06: The OUTPUT physical mappings between Rekordbox and the mixer.

Image 07: An actual proof that i have been able to "bring" sound from Rekordbox to VoiceMeeter Banana. As you can see in the image, i have green leds showing up. At this point, i'm completely able to play tracks on both physical CDJ's (individually), mix them through the physical mixer without any problems whatsoever and getting output sound on my external speakers (not the laptop ones). The different colors help identify the main settings that i have on each one of them. I am a knoob using this software so, i know there's an high probability of any of these settings are wrong or misplaced or whatever. But the thing is that i actually DO HAVE a sound signal here.

Image 08: The A1 Hardware Output mapped with ASIO: DJM-450 ASIO Driver. It seems that this driver is actually the original out-of-the-box driver that comes up with Rekordbox. Correct me if i'm wrong, please.

Image 09: The A2 Hardware Output mapped with WDM: CABLE Input (VB-Audio Virtual Cable).

Image 10: The System/Settings configuration that i have made in VoiceMeeter Banana to be able to have a sound signal here. I'm going to be honest: i don't have a clue if these settings have any impact on the sound that needs to go to OBS Studio or not. I think that A2 (or A3) OUTPUTS should be the ones that have to be mapped with the correct driver to achieve such objective, but i'm not sure how to do it. Nevertheless, these settings are working here, so far. I have tested a few different ones and try to reflect them in OBS, without any luck. Of course i would like to have any advice on how to correctly configure these as well.

This thread continues on (Part 2) as this forum only allows 10 images per post....
That second part is actually the most important as it refers to OBS itself.
 
Solution found. A simple one, as (almost) they always are.

RCA to 1/4'' cable connected from the external amp's Record Out to Laptop's Mic line in.

Sound quality stays good (from 24 to 16 bits at 48000hz) which, for a live stream is very very decent.

An additional logical mapping needed to be made from Mic to AudioMeeter Virtual ASIO driver (input).

Finally, in OBS, a simple mapping of the AudioMeeter output signal to a new Mic device.

So, resuming, External mixing from a DJM-450 with 2 CDJ's and two turntables, using Rekordbox and two cameras in OBS.

Cheers
