4GB File Limit on Orchestral Templates????

Hi Martin, I cannot upload a 4GB template. All I can say if if you have ALOT of massive Kontakt libraries, and a free afternoon, you could do what I did and create a track for every single articulation in each of those libraries until you have thousands…

I’m not sure about the track preset suggestion but I’ll keep it in mind.

I will also post a feature request so that when we use Import Tracks from Project we have the ability to use CTRL or SHIFT to select quickly a large number of tracks. Checking them off one by one is very tedious, and I certainly don’t want to do Select All.

This turned out to be quite easy to reproduce, actually.

New project
Add 16,000 disabled Instrument track instances of Halion Sonic SE. (I added an organ, disabled the track and then repeatedly invoked select-all, duplicate track)
Save project
Try to reopen, project is corrupt.

Note, Cubase memory use exceeded the physical memory (16gb here) and was using the page file, so things got very slow. I was able to save the project though. Cubase could not quit afterwards, and never let go of the more than 16gb ram it had reserved, so I forced it to terminate.

Thank you Steve!

Wow, Steve! I’m impressed! :slight_smile:

So does this mean a bug with Cubase? I’d like to understand why this is happening…

I’m also able to reproduce this. Last file size (when I cannot open it anymore) is 4.29GB.

Reported to Steinberg.

Thanks Martin. I look forward to being able to use 16,001 tracks in my next composition, Maximus Tracksimus.:laughing: :unamused:

Hi Martin,

I’m having the same basic problem (although my .cpr filesize upper limit is 1.99GB), and have lots of corrupted files, crash dump files, and other potentially-related data that I could provide to Steinberg.

Please check this thread:


I am having a similar problem.
Track count is around 5000.

Each track has an instance of Kontakt and is disabled.

It seems that I have hit some ceiling because the project file is about 2gb, but when I add just a few more tracks the size jumps to 4gb and the project become unreadable (error says project was built with Cubase 1.x).

I am using 9.5 Pro on a 32gb Windows 10 64bit system.


This should be fixed in the next update release.


Could you try with Cubase 9.5.30, please? It should be fixed for a files in range 2 - 4 GB. Files bigger then 4 GB are not fixed, as far as I know.

Please, when will file sizes above 4gb be fixed?

No, Unfortunately, no.
10.0.30 is still corrupting my cpr file after it reaches 3.99 GB((
