Interesting. Sonars optimizations that allow better low latency performance also implicitly means its using your CPU more efficiently, by keeping it busy. So its not impossible that it creates more heat on a loaded project.

Have you looked into background processes? Your symptoms sound like some background progress either consuming excess CPU or interfering with your audio driver. If it's only in this project it could also be a plug-in. Sonar cannot excess  cpu when it's not playing.

I now have to close and reopen the project, then the horizontal meters will come back and I can hit 1 to change to the correct workspace

This is most likely related to this issue which has been fixed for the next release. BTW the number keys change screensets, which are a different thing from workspaces.

I'm at 2025.07 Build 109, X64 ...

I've been noticing this issue for awhile, possibly even before moving to Cakewalk Sonar paid version ...

I often use the FX button on the control bar to bypass all FX, either for checking mixes, or to improve performance briefly while doing live recording. So to turn all the FX back on, I hit the FX button again ... BUT I've been seeing that often there are a few tracks where the FX bin shows Bypass FX Bin is still checked. It doesn't happen on all tracks, usually only a few of them. 

I'm reasonably sure it's caused by using the global FX bypass on the control bar. And it catches me by surprise because I'm not in the habit of checking every FX Bin after using global bypass.  I should say that I very very rarely Bypass the FX Bin on individual tracks ... my habit has been all or none.

Anyone else had this happen?

@Jim Stamper this has been addressed for the next release.

I have not used this new version much till now.

All With UAD 07-17-2024.cwt

File will not save in cwx or cwp format

It is a single track with feeds to many busses. It will save by right clicking on the track but not from the menu.

I know it is a lot of buses. I always start here and delete what I don't need.

@Max Arwood this was indeed a regression and it's been fixed for the next update.

I'll look when I get time but AFIK those names are not being explicitly managed by us but some middleware.

I believe it has something to do with how the framework manages duplicate names. The MRU from the standard file menu is directly managed by the UI framework.
If you have saved multiple files with the same name but in different folders, I think it puts the full path there so that the user can find out which file it actually is. Like below.



Otherwise, you'd have an MRU with 10 names that were identical so not very useful. 

It may not be ideal but its not something we're doing explicitly. I'll take a look and see its something we can control or improve.

Yeah Im sticking to that story 😛Auto correct never fails to amaze. And this is supposed to be Apple Intelligence no less.
Did you see the problem when opening files from the standard file menu or using Quick Start. Next time it happens find out how you navigated to the file.

Make sure you are scanning the vst3 version of melodyne or you can't use it as a region effect. 

Regarding the sign in message please post a video showing what's happening since describing it doesn't give us any clues.

Hmm I don't believe I've encountered that. Are you by any chance typing in full paths for golf babes  file names when opening them from the file dialog? 

 do you typically open projects via quick start, file menu by navigation to the folder or by double clicking the file in Windows?

If all you are doing is mixing try using splashtop. You will have to use wasapi shared to send the remote audio. Can't use ASIO. It works quite well to control a remote PC and listen to it's audio output. 

To use it on a local network is free but over the internet is a subscription. Fairly cheap though.

@Max Arwood I can't reproduce the issue where it displays that error message here unfortunately.

Edit: I can see the issue only if I OPEN your track template into the project then do a file save as and try and overwrite the SAME file. Please be explicit of the exact steps when reporting issues or include a video, since it's very hard for us to follow otherwise. 

If this is how you are doing it, why are you opening the track template from the file menu in the first place? Thats not the supported way to load track templates.
Track templates are intended to be opened and saved from the track menu not the file menu.

When will the delay caused by right-click dragging while playing music disappear??

If you are referring to lasso selection while playing its fixed for next release.
There was a similar issue with slip editing that was fixed for this release, that was a side effect of some update optimizations we had done for the clips view. See the release notes.

• Improved responsiveness when slip editing clips in the clips view during playback.

This worked in CWBL and in earlier versions of Sonar prior to the fee version. 

I'll take a look and see what's throwing the error.

In ASIO mode buffer size is not stored by the host. It is global across all applications and managed by the ASIO driver.
Sonar does not save or change the buffer size when the application starts up. It has never done so - in fact many ASIO drivers don’t even allow the host to change the buffer size. If its changing on you some other application is modifying it.

Back to my issue: It really IS the Focusrite Scarlett, even with the latest drivers and firmware. I tried the Tascam US-16x08, which I usually only use for recording, not for playback and it sounded fine. The only question is, why it hasn't happened with CbB.

I strongly suggest that you call Focusrite support and chat with them. Perhaps they have a different updated driver.

Your thread is confusing. There is no Sonar platinum or sonar premium. There is only a single Sonar now. 

What you get depends on your bandlab membership tier. Free vs membership.

If you load the exact same project in Cbb it is fine? 
One more thing to try is do a realtime bounce or freeze and see if there is a difference.
If you send your project file you can also CC me.

@JBS thanks for your report. We'll investigate it.

@cabrol also instead of using the freeze button do the same test by selecting the synth tracks and doing a bounce to track. Does it sound the same in that case?
This could be a plugin specific issue with bounce.

It's not possible in this case for an invalid file to have come from us because if so, every single user would have seen the identical issue.
Did you save a copy of the file before reinstalling? That would show if there was a difference. Even a single byte change in the file will void the digital signature, so disk corruption or something similar could cause such a problem as well. Looking at the file props as I showed in my screenshot would show that.

I’ve used CCleaner exclusively filtered to clean the registry but always saved a backup. Sometimes it will remove entries used by plugins because it doesnt know how stuff is being used.

Please beware of running these cleaner tools without creating a backup or restore point.

Removing redists can cause many apps and plugins to crash.

I was using Sonar (free version) yesterday with no problems. Today I get the message that I am not activated and the error message says "Sonar experienced a problem with activation. Please contact support. (20, 800b0100)". Does anyone know what this means and know how I can sort it out? If I use Sonar at the moment the save option is deactivated.

That specific error is telling us that the digital signature of the executable is invalid. The app will not activate without an exe properly signed by us.

There are only 3 ways this can happen.
1. Your exe is corrupted on disk
2. Something external removed the digital signature
3. You obtained the exe from a source other than Cakewalk installers 

The fact that installing to product center solved the issue further confirms that you had an exe that was not legit.

A proper exe should have a valid digital signature.

We default to that off because some users run into issues having too many projects open at the same time.
