Can't record sound Rekordbox + BlackHole

[carobsn]

Hello,

I've spent many hours reading posts on the forum and trying to fix my issue but it just doesn't work.
I simply want to record a mix from Rekordbox via OBS (no streaming). I had to install BlackHole since when i was trying to record the audio output, it would also record the external sounds via the microphone.
So I've installed all these software, created a multi output device in MIDI Setup, etc. Also installed both BlackHole 2ch and 16ch since I've read it could help. But nothing works. Now when i try to record the audio in quicktime or via OBS there's no sound at all.
I'm attaching the screenshots of all the setup i have. Hope someone can find where the issue is. Thanks a lot!

You are using DDJ400?

Did you try this ?

- YouTube

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

Mine is DDJ-200 and I have not been able to figure out how with rekordbox. I might be able to make it possible if I use Serato Pro + mapping + Serato Virtual Audio output.

Actually I figured out.

I am not using blackhole, fyi. Background Music is another virtual audio device open source software alternative that is compatible with M1 macs.

My equipments:
- Macbook Pro M1 ('14)
- Pioneer DDJ200
- Headphone with wire

Software:
- MacOS Ventura
- Rekordbox 6.6.11
- OBS Studio 29.0.2
- Background Music Virtual Audio Device (https://github.com/kyleneideck/BackgroundMusic)
- Audio MIDI Setup (included in MacOS)

1. Launch "Audio MIDI Setup"

Add an "Aggregate Device". Make sure that the name reads "Aggregate Device" case sensitive, otherwise Rekordbox will not recognize as we want. And then add devices, Background Music and External Headphones.

You want to make sure that you add "Background Music" first so that Rekordbox sees the Master output as Master output.

2. Launch "Rekordbox"

Go to the settings menu (accessible by clicking on the Gear icon in the main window), then open the Audio tab. Choose the "Aggregate Device" you just created as the Audio device to use.

Scroll down to Output Channels, select Headphone / Booth output as in the screenshot down below.

3. Set up system configuration.

Go open "System Settings" of your MacOS then choose Background Music as the output audio device.

"Background Music" has a configuration application. You can open it (I always use Spotlight search) and choose the built in speaker or anything else that you might want to use depending on your needs.

Now test your Rekordbox and DDJ audio outputs to make sure everything is working.

4. Set up OBS Studio

Now you can finally add "Audio Input Capture", choose "Background Music" as the input device.

Note: you are seeing a screen of iPhone because I am planning to use my iPhone as a video camera device.

IMPORTANT

You have to Audio Monitoring to Off or you will have a feedback problem. And you will also have to adjust the audio level accordingly.

That is all set. Now you can probably start streaming or recording. I hope that it helps.

Also thanks for helping me to write a script for another video I was thinking to make. It was a good opportunity and encouragement.

You can avoid the feedback issue by setting it up as detailed here

Normally, I'd report that as spam, because it matches what spam often does. If that link with a hidden URL went to something that appears unrelated, as they often do, I definitely would.
But because it goes to a post on another forum for a similar topic, I won't.

To be nice to everyone else though, and avoid setting off more spam detectors, can you copy/paste the answer here?

You are right, I agree with you.

Since nothing is coming through now, double-check that Rekordbox is set to output to the multi-output device. Also, ensure OBS is capturing the correct input source. Sometimes, restarting after setting up BlackHole helps. Have you tried testing with a simple recording app before OBS to isolate the issue? Hope you get it working! I am a college student and sometimes I feel the need to seek help in writing work. If you’re also looking for a trustworthy academic online writing service, I highly recommend Academized, which is available https://academized.com/ here. I used it for my economics paper, and the results were fantastic. The writer followed all my instructions and delivered a well-researched, professionally written paper that impressed my professor.

Thank you so much, you saved my day.
