I have installed C12 on my brand new iMac M1 and unfortunately the export of files (audio mixdown) takes incredibly long. It takes me ca. 2 minutes to expert an 18 minutes audio file. Just audio, nothing complicated. I had no such problems with C11 on my five-year-old intel-based MacBook.
PLEASE HELP!
Do you know if Cubase is running in Rosetta mode? If you are running native and you have intel plugin’s saw somewhere that can slow things up. I just have a new M1 MacBook Pro M1 Pro and so far so good. Did you get 16G of ram? How many tracks? How may plugins? Maybe it is a plugin that is causing the issue.
If you go into Activity Monitor (spotlight search activity) you might be able to see what is holding it up.
Anyway, hope this helps and you get it sorted out.
Hi, Cubase is running native. Yes, I do have 16 GB ram. I had installed Waves’ “DeBreath” plugin, but deinstalled it, as I could not really make use of it. Just now, I have 13 tracks and it took nearly five Minutes to export just one of those tracks (a 25 Minute file) in .mp3. This can’t be the way it is supposed to be, can it?
Take a look at the bigger thread over here, the issues seems to show up when exporting to a different sample rate than the one you are working on in your project, thats why it most probably did not affect everyone.
Same here. MacBook M2 Max is incredible slow at exporting. It nearly is as slow as a real time export. Any suggestions?
Running on a M1 macbook here and when I first got it, everything was super fast. Now offline mixdown takes twice as along as the realtime. It’s not the difference in samples rates as suggested above - I have both at 44.1/24 and tested different settings, still slow. I am running on Rosetta still, because Stainburg and Universal Audio can’t get their act together either.
Did anyone make any progress on this slow issue though?
same same, mac mimi m2 pretty slow with very simple exports. i first tried native but C12 was crashing a lot! with rosetta it works but still the exporting is slow. are we doomed to go back to windows 
I’m on a MacBook Pro M2 Max on Nuendo 12.0.70
Export is extraordinary slow compared to my Windows machine. Allthough the realtime performance from the MacBook while working, outperforms the Windows machine by far! So I don’t get it… super annoying.
Export speed is mind-numbingly slow. For most of my projects it’s about the same speed as real-time, and it’s still not fixed in C13.
There are at least a couple of problems. For one, Cubase is using the wrong buffer size during the export. This slows down the export, but it also means the export isn’t processed the same as when you’re playing back the project, which can lead to audible differences.
The bigger problem is the under-utilization of the CPU during the export. It’s hard to understand why Steinberg hasn’t fixed this.
How do you know that?
IIRC whith higher buffer sizes my exports are much faster than with lower ones, so I cannot confirm that.
Didn’t really take a look at the CPU usage during export lately, but the last time I looked it was using quite a lot of CPU, but not 100% (don’t know if that would even be possible).
I measured it in plugin I wrote for that purpose.
100%? That would be impossible. However, during an export it should be using more CPU than during playback, but that’s not happening. That’s the primary reason the export is so slow. My exports are typically no faster than real-time playback.
Are you using an M1, M2, or M3 cpu?
