Control room tab: Between 1 and 2 second lockup when switching between Stereo and Mono

Hey, guys.

Toggling between stereo and mono in the control room view of the right panel was instantaneous in both 9.0 and 9.5. In 10, the song locks up for between one and two seconds, then resumes in the new mode. Specifically, the UI freezes and audio stops for this duration. When it resumes, the switch to mono or stereo behaves as expected, and the song position updates to where it would have been were there no lockup.

I’m able to reproduce this in a very simple project with one audio track and no vst instruments or plugins. I first posted a question about this in the general forum. The only feedback I got was from people on Macs, who reported it working normally. I’m on Windows 7, so it may be specific to Windows. Since I can’t reproduce the problem in 9.0 or 9.5, it is in any case specific to 10.

Steps to reproduce:

  1. Open a project with at least one audio track in 10 and begin playing
  2. In the control room tab of the right panel, click the button to toggle from Stereo to Mono or vice versa

I frequently check my mixes in mono and this is disruptive enough that I’ve gone back to 9.5 for the time being. Hopefully it will be included in the next round of fixes.

Let me know if there’s anything I can do to help on this one.

Hi,

I can see, you report this several times on different places of the forum here already.

I mentioned it in the regular forum first because I wasn’t sure if it was a bug, then put it here once I was. I did also mention it in the guy’s thread about going back to 9.5 from 10 as I thought people would list their show stopper issues there and have it be useful, but since you mention the duplication I’ll delete it from that one. Apologies for the redundancies.

By the way, my understanding is that this is the place to report bugs, but I’m not entirely sure of that.

If that’s not the case and there’s a different place to report them, could someone please point me in the right direction?

Hi,

Yes, this is the place.

I’m still not able to reproduce it. How many Output Buses do you have in the Audio Connections? Could you attach your preferences folder, please?

I noticed this too, simple audio setup with just 2 output busses (using RME FireFace UC).
When I clicked on MONO in the Control Room, all went mute and stopped for few seconds until it continued to playback in MONO and vice versa.

Hi,

More details would be appreciated…

Do you use 32- or 64 bit float Processing Precision? Is ASIO Guard enabled? What ASIO-Guard Level do you use?

I’ll gather as much info as possible and will follow up. Where would I see the preferences folder for 10?

Hi,

On Windows you will find the Preferences folder here:
%appData% Steinberg/Cubase 10 64bit. Zip this folder and attach it, please.

Thanks, Martin.

There is no Preferences folder in the folder you mentioned (see screen shot for contents). There is, however, a UserPreferences.xml file, which I’ve included in case that’s what you meant.

I have no connections in the Outputs tab, and a single stereo connection used in the Control Room tab. I’ve included screen shots for both of those, as well as a screen shot of the full VST Audio dialogue to give you all those settings. My audio interface is a Yamaha TF5 mixer, which connects via USB with the appropriate Yamaha driver.

Is it possible when trying to reproduce that you’re using a stereo bus from the Output tabs rather than monitoring via the Control Room? That might be a significant distinction.

Please let me know if there’s anything else I can do to help with the debugging (I pay the bills as a software developer so I’m used to the adventures).



Here’s the VST Audio screen shot and the user preferences xml file. Apparently there’s a limit of three attachments.

By the way, I zipped the entire Cubase 10_64 folder in case that’s what you meant by “Preferences folder” but at 3.5 megs the website said it was too large to upload.
UserPreferences.zip (12.6 KB)

Hi,

Yes, the Cubase 10_64 is the preferences folder. Could you share it via Dropbox or similar, please?

I rested with both: Stereo Out and Monitor 1.

Here’s the zipped up file, thanks.

Hi, Martin.

The only other variable that comes to mind is the operating system, so I just ran Windows Update, installed all updates then rebooted a couple of extra times for good measure. The problem remains.

Are you testing on Windows 10 or Windows 7?

Hi,

I’m testing on macOS 10.13 and Windows 10.

Thanks, Martin.

I’m experiencing the problem on Windows 7.

Windows update was run just a few days ago and it’s completely up to date.

Hi,

Yes, I can see it in your sign. Unfortunately I don’t have any Windows 7 machine, where I could test.

No worries, man. I appreciate you trying to help as much as you have.

Since Windows 7 is a supported OS, I’m sure the Steinberg guys have a testing environment for it. Are you able to forward this bug report to the appropriate people so it can be fixed in the next maintenance release?

+1
I am on MacOS 10.12.6. All my settings are the same as in 9.5, except I switched to 64-bit float Processing Precision in 10.

Your’e experiencing the bug as well?
