Why does my mono group look like a stereo group?

Hi - Such a basic question, sorry …

I want to pan the output of a group channel hard right.

Initially I had set up the group as a stereo track, but when I panned it hard right, I still heard its output in the left channel.

So to try to fix that I created a mono group (as in the pic, with the red pencil highlights), and routed the stereo group to that mono group.

But I noticed the track on the mono group had a left and a right channel display. Shouldn’t that be a single “mono display”?

So confused … please help!


Well, it doesn’t at my place with C12.0.30. Which Cubase version do you have?

Anyway, I think you should rather have a look why you still heard something in the left channel when you panned the group track hard right. If all the routing is correct and you solo the group, there should be nothing on the left channel
Have you checked that you don’t have e.g. any FX-Channels set up on your tracks or group, like a reverb, but that FX-track is routed to your Stereo Out? That would explain why you still hear something on the left side.

Thanks, @fese .

Pro 12.0.30 here.

I will go back and recheck my routing for the nth time, thanks for answering how it works on your system.

There is still something i don’t understand though, as in my attached pic in OP: Why does the mono group have fader display showing a L/R channel (“circle #2”, the one to the right of the one circling the word “mono”)?

Can’t help you there, I just created a mono group track, and it only has one bar in the meter, just like a mono track. Maybe there is some setting that I don’t know about.

Thanks again, @fese .

Anyone else know why my mono group track has a L/R fader display, as in pic in OP?

Thanks in advance for any help :slight_smile:

Addendum: I can add that, weirdly, the stereo group has fader display suggesting it is actually mono (has only one bar, not a Left and Right bar)!

Totally confused here! I guess I’ll try to start project in safe mode and see what things look like …

And thanks please for any ideas what might be causing those apparent “wrong” group mono vs stereo fader displays!

It’s because you are routing the Mono Channel to a Stereo Channel (ALL VOX). The panner is determining where the Mono signal will be placed within the Panorama for ALL VOX.

Hello alexis,

I took my project, deleted the stereo electric guitar group and created a new one, now in mono. I get that

I think it is the same that you have. But now, if I pan to the left, I get more MONO sound to the left side. Same with panning to the right. You don’t have stereo sound anymore, but can balance how much is in each side with the pan control, just as raino said above. And you can’t set the panning in individual tracks anymore.

Atention: I wrote a post some minutes ago with other results, but must edit it, as I had made a big mistake in my setting.

Like Raino wrote it depends on what the destination track’s channel count is, AND what your meter is set to.

If you have a mono source going into a stereo destination track then you get a panner. If you set your meters to post-panner then you’ll get the two ‘bars’ which reflect the panning. If you set your meters to post-fader they will reflect levels after the fader but before panning which means you only get the one bar… as far as I recall…

You should always think of these things as separate but related:

Create tracks as needed with the required channel counts.
Set meters according to the information you need to see.


A lot of us always use Stereo Channels/Tracks for everything, even Mono content. That way things work as expected and there is no need to waste your time or energy trying to manage the Stereo/Mono interactions. I highly recommend adopting this approach.


Thank you @raino and @MattiasNYC and @Knopf !

My original goal was to have all the backing vox (“Aaahs”) be hard panned right (always using a stereo group … the mono was only added to troubleshoot the following problem):

But what happened was I panned the Stereo Group (“BV AAAH Stereo”) hard right, and still heard a lot coming out of the left channel - can’t figure out why!

I’ll triple check all the routings again for the nth time … it sounds like operator error on my part … can’t be anything but, right??

Thanks -

Apologies all around … Control Room set to Mono … :roll_eyes: #f’inembarassed

Yes, that makes sense, I forgot about post panner meters. I’ve always been irritated why the default is not post-panner, it is rather confusing if you move the panner and the meter doesn’t reflect it.

I’ve been making my vocal ins mono, I’ll just change things to stereo from here on in.

Thanks, @raino !

Though early on in mixing i like when the meters are set to input, so i can see how hard i am hitting certain plugins

Just be aware that having every track in stereo will probably increase the CPU usage for plugins on those tracks as they now have to compute the double amount of data.
Personally I work mostly with mono tracks, at least for mono-miked signals and usually don’t have problems with that. Each to his own, I guess :slight_smile:

Same here. I also like that with mono tracks I get a clear indication that the audio on the tracks actually is mono. With stereo tracks I can’t tell as easily.

The way I deal with that is while all the Audio Tracks are Stereo only some have Stereo content while the others are Mono. So for the ones with Stereo content I use Stereo Combined Panners but for the Mono content Stereo Balance Panners. That way it is really visual which is which.

I stopped using Mono Tracks a few years ago. One thing that pushed me there is that you can’t use stereo effects on Inserts - like a multi-tap delay on a mono vocal Channel. So when ever I wanted something like that I had to route it to a Stereo buss first, or add a Stereo Audio Track and drag the mono content onto it. Eventually I realized why not start here to begin with?


That’s an interesting idea.

This can also sense from a technical standpoint, because the Stereo Balance Panner is basically a connected fader for the left and right channels. If you have a stereo recording, where for example the left mic is a Cello and the right mic is a Violin, hard panning to the left will actually make the Violin disappear.

The Stereo Combined Panner instead behaves like two mono panners for both channels, ensuring that no details from the original stereo source are lost.
