Recording Karaoke performances with UI24R

[PBrilino]

I’m trying to record outputs 3 and 4 as a stereo wav file on my Mac. I think I’m following the right process, but for some reason, the wav files show up as zero bites, and they’re not playable.

1. I’ve made sure that I’m getting audio out of 3 and 4:
   
   
2. Made sure I have the right channels selected when hitting record:
   
   

When I click record, I see the files in my Recordings folder, but they are zero bytes and won’t play:

Not sure what I’m missing here…any thoughts?

Thanks!

Can you upload the gig file?

Edit: or some print screens of connection? Wiring view

[PBrilino]

Sure. Here’s a screenshot of the wiring view and the gig file.

What happens when you record the corresponding input?

I just tried that, but it gave me the same result. Basically, what I’m trying to do is to record a backing track from the Karafun Karaoke app on my mac, along with a mic from my UI24r interface so I can record people’s Karaoke performances. The Karafun app doesn’t have any routing in it, and by default it just plays through outputs 1 & 2 of my interface. That’s why I have it routed from input 1&2 on the interface to 3 & 4 on the outputs.

The audio routing all seems good, because I can hear everything through my speakers, but the recording just outputs those empty files for some reason. I’ve tried recording several minutes of audio, and it still results in the same zero byte wav files.

That will not work, you need an interface with loopback option
For example like an RME interface.

Well… I have an UI24R and it’s very flexible routing wise; why not record on the UI24R itself?

Sounds to me like there is no audio coming into GP to record

[PBrilino]

Yep, I think that’s what I’m going to do. I was hoping to record directly on my mac because it would be a little bit easier to access the files, but I guess it’s easier just to record to a USB stick on the ui24r.

The Karafun app doesn’t have any routing in it, and by default it just plays through outputs 1 & 2 of my interface.

To make this to work, you need to route audio between apps, i.e. from Karafun to Gig Performer. Check out Blackhole – BlackHole: Route Audio Between Apps

When you feed audio into Gig Performer. it will then effortlessly record it. Give it a shot.
When you install Blackhole, look at the Karafun audio settings and select blackhole.

Then create an aggregate device on your macOS combining your audio interface and Blackhole.
Start Gig Performer and process your sound further any way you like and record your dry/wet audio streams.

We are probably missing something?!…

I think the issue is related to the fact that patching is a littlebit tricky on UI24r.
DAW Input Channels 1+2 are Master Out, 3-10 are Aux Busses
So the Input Channels are starting on 11.

Try recording 13+14.
