Cubase 12.0.60 hanging more frequently on exit

rickpaul · May 19, 2023, 9:17pm

For various reasons related to timing and schedule, I hadn’t been using Cubase Pro 12.0.60 (on Windows 10 Pro, fully updated) much until recently. Recent versions had pretty much done away with the hanging on exit that I experienced frequently in some early early versions of Cubase 12, but it seems like the more frequent hang is back, as I’ve had a couple of recent hangs after sessions of several hours (e.g. about 4.5 hours yesterday).

The specific scenario seems to be that I close the project first, then wait for the Windows close button to turn red when I hover over it, then try closing that, but it hangs. Yesterday I took a procdump after it had hung for some non-trivial number of (I’d guess at least 10) minutes. The DMP file (inside a ZIP file) can be found at:

I also did a quick analysis of this in WinDbg Preview, and it shows the following:

---------

Prior to killing the process (and also prior to taking the procdump), I checked in TaskManager to see what it was showing, and here is the result:

It may be worth noting that the project was running at 96 kHz (since I know there was some earlier Cubase 12 issue where the sample rate and time spent in Cubase apparently mattered with respect to likelihood of hang). In this case, though all the Microsoft Edge WebView2 processes seem to be a new thing (or at least I hadn’t seen them previously as Cubase subprocesses).

Hi,

Please make sure your plug-ins are up to date.

rickpaul · May 19, 2023, 10:59pm

I’m pretty sure my plugins should be up to date. I check for updates pretty frequently and update whatever needs it at the time.

ericmusicstrasbourg · May 20, 2023, 9:15pm

I have the same problem

synthmusic_51 · May 20, 2023, 9:51pm

Hello, I started to use Cubase with version 9 and it has always worked fine except this hanging problem. Then this problem almost disappeared maybe with Cubase 10 or 10.5 (I’m not sure).
And with Cubase 12… it’s back.

The scenario (several times a week) is like yours: I close the project then I hit the red Windows cross and nothing happens until I kill the task

OR (new case with Cubase 12)

all seems to be fine but when (for example the next day) I launch Cubase again, I see that it didn’t close correctly the time before…
Otherwise Cubase works well, so it’s not really serious but somewhat annoying.

I think that third-party plugins are faulty, because that often happens with some projects and not others. It seems that some plugins doesn’t clean up memory upon closing…
I have noticed that the following manufacturers are very often present in my “faulty” projects :
ToneBoosters (TB Barricade)
AIR Music Technology (great plugins but that sometimes freeze some projects).

My audio interface is a Roland QUAD-CAPTURE (see complete configuration by clicking on my nickname).

I hope that helps.

I believe I started with Cubase at 9.5, but only started using it as my main DAW for new projects around 10.5. I don’t recall having many hangs on exit in those earlier versions, but I did start seeing it with Cubase 11, especially in the case of Waves Nx series plugins (e.g. Abbey Road Studio 3, Ocean Way Nashville, CLA Nx) being live prior to Waves’ adding the ability to turn the head tracking off by default. Once I could do that, the hangs on exit became pretty rare, so I was attributing them to the extra (outside of Cubase) Window those plugins put up for head tracking (which I wasn’t using anyway for lack of appropriate hardware).

The hangs on exit came back big time in some of the early versions of Cubase 12. I don’t recall now if it was the first (.0) release or .10 or .20, but then it became regular. There was a theory (I think later proven correct) at the time, that there was some sort of counter (sample counter maybe?) inside Cubase that should have been a 64-bit variable but was only a 32-bit variable), and higher sample rates (I almost always use 96-bit) would see the issue earlier, while longer sessions could almost guarantee it with high sample rates. This issue got fixed at some point (.30 or .40 maybe?).

I haven’t used Cubase Pro 12.0.60 sufficiently yet to be sure of a pattern. However, I can say I had a pretty long session yesterday where I did not experience it. Just thinking about it now, though, it is possible I broke that session down into two separate sessions due to some other weird thing I was experiencing with getting sound from a specific track.

I have seen this one, with freezdump.dmp files created frequently with two specific plugins, and only for the first load after a reboot. The two plugins are Kontakt (both 6 and 7 had this issue – not sure about earlier versions as I was already using Kontakt 6 by the time Cubase 12 came around) and Guitar Rig Pro. To date, I have not noticed it with other NI plugins. I think there is something there about the length of time those plugins take to initiate (possibly reading their libraries and large numbers of presets, respectively?) because that first load after a reboot takes an extraordinarily long time (even if loading Kontakt standalone), and Cubase seems to assume it has become non-responsive, though it eventually loads and works fine. In that case, the freezedump is essentially a false alarm. I was trying to look into this with NI, but nothing they suggested ended up changing it, nor seemingly led to any clues as to what made it happen. However, a Steinberg developer did mention the thing about the non-responsiveness and the “simple” mechanism used here. (I have a pretty slow system disk and many, many plugins, though my sample libraries are not loaded on that disk – the disk they are loaded on is of similar vintage, but doesn’t tend to get bottlenecedk like the system disk can.)

I don’t have that plugin, or any from that developer. In the project I had running recently, it was mainly Waves StudioRack plugins, with other plugins loaded inside those, plus Ozone and a PSP Audioware dither plugin, plus some IK tape emulation plugins. On the virtual instrument front it was a few instances of Kontakt, EasyDrummer 3, IK MODO Bass 2, and maybe an Acoustic Samples guitar library that runs under UVI. But most of the virtual instruments and plugins on those tracks were frozen at the time of the hang. I think there were only a few live plugins on group tracks.

I am pretty sure that the plugins that were live at the time were up to date. (I actually checked this morning to be safe.)

rickpaul · May 20, 2023, 10:19pm

One additional note is that the WebView2 instances seem related to Waves StudioRack, at least when using it with StudioVerse (which I have been doing). I noticed this yesterday when inserting a new instance of StudioRack stereo, where there hadn’t been any instances of WebView2 in Task Manager ahead of that, but then inserting the instance created something like 3 instances.

synthmusic_51 · May 21, 2023, 1:01am

I also use many NI and Waves plugins. Kontakt and Kontakt Player are really really slow to load the first time in a session. It’s a well-known NI problem (even in standalone mode) that they attribute to some other programs like antivirus but I am not convinced.

rickpaul · May 21, 2023, 4:42am

At least on my system, the slow load of Kontakt (and Guitar Rig) is only the first time after rebooting the system. Thus, I am attributing it to needing to load whatever it is loading from disk, whereas after that it is likely cached in memory. It often takes upwards of 5 minutes on my system.

That said, some Waves plugins can also take multiple minutes to load on a first load (not just in Cubase, but also Cakewalk), though typically not as long as that first Kontakt load after rebooting.
