Channel overlaping (poltergheist)

Hello again,

I’m having a small problem with recording on the channels. As you can see in the attached video https://youtu.be/nGjx4oKGPPE, when I open a new project, I set one channel for the guitar and another for the vocals. However, when I’m recording the (electric) guitar, the vocals are also recorded on the same channel. How can I prevent this? I understand that the guitar strumming is being picked up by the vocal mic, because I can hear it, but the amplifier signal is also being picked up. Both channels are coming out mixed with the same signal (electric guitar and vocals).

I suppose it must be a settings issue, but I can’t figure it out. Could you please tell me what I’m doing wrong (besides everything else)?

Hi, @smokeadvisor

What we see is the record occuring in the Guitar track, as expected as it’s the only one being Record activated. Nothing is recorded in the Voice one, as expected also. The problem is that, beside this, your video doesn’t tell us a lot : we don’t see what’s left in both channels when you stop the record process.

Beside this, could you precise how the guitar is amplified ? There are the two separate tracks, each one having its own hardware mono input, but this doesn’t let us know what’s upstream the Streaming 1 input for the guitar track, in example. Additionaly, when the recording occurs, I see no input signal in the Guitar track meters : rather strange. I would double check all your connections and be sure that the audio signal coming in your interface actually goes in Cubase (any Direct Input Monitoring setting involved ?).

If nothing is recorded in the second (Voice) channel, something else is also occuring during playback, probably related to your audio interface output configuration.


EDIT - Another thing : be sure that there is no other sound source involved, such as an eventual onboard sound chip, which wouldn’t have been deactivated.

Hi Cubic13,

Good afternoon. First of all, thank you very much for replying to my message. I’ll go to your comments and see if I can answer them correctly. Regarding the video, you’re right, the vocal track is missing. In this second video, both tracks are recorded https://youtu.be/CdA4uPbuygI.
The guitar is amplified by a Tonex Pedal and goes into line one of my UR24C through a DI box.
The microphone goes directly into line two of my UR24C.
Regarding the recording, there is a signal in Cubase. You might not hear it because my capture software isn’t picking up the audio correctly (I need to check why).
In Cubase, while reviewing the track routing, I’ve seen that despite assigning different routings, both tracks “magically” end up on the same path.

As you can see, I finally managed to get each track to have its own routing, but they’re still recording the same signal. I’m going to check if my house is built on an Indian burial ground. In the meantime, if you have any information, I’d appreciate your help. :wink:

The strange thing is not wether I’m hearing something or not, but rather that there is an incoming audio signal that seems to have the exact same level and behavior on the time line, despite each channel having its own input and devices configuration. This, with no equivalent signal incoming in the audio tracks. So, few other questions (while scratching my head…) :

  • Any other device (or software, who knows…) that could mix the two signals upstream ?
  • What is the mic that you are using for the Voice track (dynamic, condenser…) ?
  • How each channel behave when monitoring one (using only the Monitor button in each track inspector), then the other without recording ? Same exact sound in both channels ?

Beside this, I guess that there is a dedicated ASIO driver for your UR24C unit : I would get rid, in the Studio > Studio Setup > Audio Setup panel, of the Steinberg built-in ASIO driver and install, then load the former instead, if there is one. Tedious, as you’ll have to make all the routing/busses creation again, but worth a try, I guess.

Did you only open OBS to record the video, or do you always have it running while you’re using Cubase? It would be a good idea to simplify your configuration–make sure there’s nothing but Cubase running–to rule out any signal-routing side-effects from other software.

This is odd. You’re recording on two tracks, and there’s no activity on either meter. I would disconnect everything and start over with configuring only the first Mono channel. Don’t add the second until you have it working correctly.

Hi again Cubic,

Thank you so much for your input. I’ve finally solved the problem https://youtu.be/ZQquCYWaRjo. For whatever reason, the ASIO driver configuration wasn’t done correctly; I imagine the installation of a plugin must have done something to it (I’m guessing).
To fix it, I did the following: In the safe mode dialog box, I discarded the configuration, so when I restarted Cubase, it asked me to reconfigure the audio.
At this point, I reconfigured the ASIO inputs and outputs and in the audio settings, I assigned a single mono input bus with two channels. The hardest part was accessing the safe mode dialog box, as I had to create an error to see it. I don’t think it was the best way, but oh well, I managed.

Thank you so much for your help.
