I’ve been getting some concerning drop-outs lately in my Mac Studio M1 Ultra, a machine that has far more power than required by Cubase and many instruments loaded, unless of course there’s something wrong with it, but I don’t see anything weird in any other software.
At first I thought it was a project I downloaded from the VSL tutorials page, and those projects all use the Vienna Ensemble Pro server to load the instruments, but I don’t like that workflow, so I like each track in Cubase with its own instrument. So I converted that project in a way to be the same but use the VSL Synchron Player in each track.
Once I finished, I started playing back the timeline and just a few seconds in, it started stuttering. I would press stop, then play again, and same thing. I don’t want to make this ten pages long, but basically it seemed to me that Synchron Player was the culprit, because this was a rather short number of tracks compared to other projects I had opened and played without problems. In fact, recently I downloaded the Cubase project Lorne Balfe posted for Mission Impossible Fallout, which has over a hundred tracks, and since the project was from 2016, I had to replace everything but a few things, because even the libraries that he had back then were under Kontakt 5, so either I was going to do this project in Cubase 12 Pro Rossetta mode or replace everything with Kontakt 7 and my instruments.
Well, that project played from start to finish without any hiccups. But this smaller project, that had mostly the Synchron player with two VSL libraries was so heavy that it felt like using a machine from 1995.
So I thought it was that the VSL player and/or libraries were not optimized for Apple Silicon and that was it, after all, I searched online and many people were having the same issue.
But shortly after that I started noticing that Cubase Pro 12 was causing my mouse to stutter, like I would be moving the pointer and suddenly it froze but a quarter second later it would appear where it should’ve been. I will note here that I have a Microsoft Sculpt mouse that is USB, but I have the USB receiver connected to a USB extension cable that goes to my Mac, so the receiver is less than a foot away from the mouse.
Then I noticed that more and more, projects that had barely any tracks, were also playing with hiccups, and the audio performance meters were showing the peak going all the way to the right while I was hearing those hiccups or drop-outs, whatever they’re named.
Obviously I did all the usual troubleshooting, like setting the interface buffer to 2048, disk preload to 6 seconds, enabling and disabling the ASIO guard, etc.
The internal storage in this machine is 4 TB, and it’s the fastest drive I’ve ever had. According to the Blackmagic Disk Speed app, it goes up to 7 GB/s. At this time it’s not full, even if it’s close to, but it has 400 GB of free space.
So this kind of thing should not happen in a machine this fast. Everything in this machine is insanely fast, and every app that I use in it is just as fast. But there’s something going on. If this happened a year ago, I would probably go for the sure thing, meaning backup, wipe the drive and install the latest macOS version.
But that’s not an option anymore, because in the last year I have bought so many libraries that the 4 TB drive is not enough for all of them. I had to buy an OWC 4 TB SSD to put the rest of the libraries. So the usual downtime to make a backup, wipe the drive and reinstall macOS plus all the apps I have is a process that takes me several days before I had all these libraries. Right now, it would take me two weeks of reinstalling everything I have, because I know that it’s not just a matter of making a backup of all the libraries and then just install the software from each company and relink. For some companies it is, but I have read that people have had trouble doing that with Spitfire libraries and other companies as well.
So I need to find a solution, and see what’s causing all these spikes in CPU usage that I keep having. Granted, this seems to get worse the more tracks I have, because I don’t get them all the time. But today I started a new project, then dragged an audio file, and that caused a peak.
I already trashed the preferences recently, before Cubase 13 came out. I can try that again, but it’s a royal pain to set everything again the way you want it.
Any suggestions?
