Switching projects causes crash in Cubase Pro 8

Ongoing issue here with Cubase Pro 8.0.10 (and earlier versions including Cubase 7.5) on OS X when switching projects:

  • simply close current project (Cubase stays open)
  • load a different project (no matter if from “open recent”, from Finder, etc.)
    -> Cubase crashes (I would say 80%-90% of the time)

The Apple “Problem Report” always comes up with the same thread that crashed:

Thread 40 Crashed:: Baios Processing Thread
0 ??? 0x00000001360092b0 0 + 5200974512
1 libsystem_pthread.dylib 0x00007fff8e5fa451 _pthread_exit + 117
2 libsystem_pthread.dylib 0x00007fff8e5f9273 _pthread_body + 142

The “Baios Processing Thread” can can be at a different thread position, but it is always the exact same message. What is this?

Current setup:
2013 Mac Pro 8-core, OS X 10.10.2, Cubase Pro 8.0.10

Former setup (which had the same issue):
2009 Mac Pro 8-core 2.66 GHz, OS X 10.8.5, Cubase 7.5.3 and Cubase Pro 8 (initial release)

I’m not 100% certain anymore, but I think I had the same already with Cubase 7.

PlugIns used in current projects amongst others (these vary a bit depending on project):

  • VSL Ensemble Pro 5 (several)
  • NI Kontakt 5
  • NI Battery 4 (not in all, but most)
  • NI Massive
  • Steinberg PadShop
  • various Waves plugins
  • PSP AudioWare plugins
  • SoundToys (mostly EchoBoy)
  • u-he software synths (Zebra 2, Diva, Bazille, Hive)
  • Valhalla reverbs (the crashes also happened before I got these, these can’t be the culprit)
  • Expert-Sleepers “Silent Way” suite (to integrate a modular system)

I can send/post entire Apple Problem Reports as this is fairly easy to reproduce on my setup.


Just now had another crash. This time not from changing projects, but from trying to open a template. Crash happened immediately after selecting the template (nothing was attempted to load - it crashed right away).

Sorry for my english =V

I have the same issue, Switching project crashes Cubase Pro 8 all the times, I have to close the program when changing project to keep the changes I’ve made in the last one.

Sometimes crash when I import an audio track or create a new one. I really like Cubase 8, but is very unstable for me, much more than Cubase 7.5

It also gives me latency problems between tracks that never happened to me in C7.5, especially with Kontakt, and many times I must correct the latency in milliseconds on each track

My setup is:

MacBook Pro Retina 15,4"
Intel Core i7 Quad 2,6 GHz (Turbo Boost 3,8 GHz per Core)
16 GB de RAM DDR3 1600 MHz
1 TB SSD Flash
Nvidia GT 750M 2 GB GDDR5 + Iris Graphics 1,5 GB
Mac OS X 10.10 Yosemite

I think I’ll have installed Cubase 7.5 and Cubase 8 Pro at the same time, and work with both, but I paid for the upgrade and want it to be much more stable


Cubase Pro 8 also fails to detect some plugins that were detected either in Cubase 7.5

Too many issues slowing my workflow =(

I encounter the same problems : Cubase Pro 8 (8.10) often crashes when I open another project and I active it !
I’ve got a i7 2600, 16 GB, Windows 8.1

I just downloaded the version 8.0.20 and now it seems ok !!!

I am having a similar problem with Cubase 8.5 on my Mac Pro. It seems like Cubase will crash when it accesses the Finder, more often after Cubase has been running for a half-hour or more. Tasks like opening a project, doing a “save as”, choosing a file path to export to, and even quitting Cubase will cause a crash. Deleting prefs and disabling plugins has not seemed to make a difference. Any ideas?

Mac Pro (Late 2013) running 10.10.4, and Cubase
2.7 GHz 12-Core Intel Xeon E5
32 GB 1866 MHz DDR3 ECC
AMD FirePro D300 2048 MB
MADI Xtreme audio I/O via Thunderbolt

Crash Report Posted Here

I have similar issues on the two machines in my signature and the problem has been ongoing since C7.0. I have discovered that the chances of this “crash on quit/switch” are at their highest when I have used the internal preset systems of plugins such as U-He, Native Instruments, Waves, Arturia…etc. If I save my Project and close, the chances are high I will get a crash. After rebooting, I won’t have that problem quitting the same Project…unless I change a preset somewhere. If I work on a Project and don’t make any preset selections within any of the plugins, chances are it won’t crash when I close it or quit.

If you look at your crash logs, you’ll notice that memory allocation is crapping out by Cubase not being able to tell where the preset’s RAM address, chosen in the Project, was supposed to be stored at. This seems to be exacerbated by Cubase’s virtual memory scheme (VM regions) fighting with the memory schemes used by some of the plugins…NI immediately comes to mind.

It would seem that Cubase assigns a temporary memory location for presets chosen within the plugins and then forgets where they were, upon closing, as it does its file cleanup routines. I dunno, this is just an empirical guess on my part, but it’s something Steinberg probably has seen dozens upon dozens of times over the last 3 years and has (pardon the pun) not addressed.
