NO rant , just facts Cubase 13 Audio engine Spikes compared to Cubase 12

Acustica stuff doesn’t play nicely at all with Cubase in my experience. I have stopped buying their software as a result. Sienna is unusable for me at 128 sample buffer. Completely unstable inside of Cubase, or running inside of Audiogridder locally.
I swore off buying any more of their plugins after my experience with Sienna. I made them aware of issues, and they did the bare minimum to get it to stop causing Cubase to hang on exit, or randomly freeze and that was it.
I did end up getting Mystic recently… I don’t even attempt to use their plugins until I have completed all tracking, and upped my sample buffer to 1024.

I tend not to believe the hype with Acustica. There are much better optimized algorithmic based plugins that have much smoother workflow, and either just as good, or better results.
Pulsar Audio, Pulsar Modular, Vertigo Sound, Wavesfactory, Relab, Universal Audio, Tone Projects…Etc.

Ummm , i think am @Norbury_Brook Markus was sort of trying to point out , they are very system specific , my whole last build was geared round Acustica , but by G’s own admission , the new Hyper tech is geared round the new processors so , i’m an advocate for keeping old tech alive especially if it’s the top of the chain tech so , between Steinberg having some sort of Over Sampling leak and AA having Naffed up over sampling on it’s last 4 releases ive decided to go back hardware based , lighter load on the Cpu .
Everything was fine till their Ash Ultra release and then iyt completely Naffed up my system , unrepairable but unlike Steinberg , who jumped on the Situation and acknowledged there was an issue , AA tried to keep everything closed , you were not allowed to discus with others to see if they had had the issue and more importantly a resolution , the post was deleted and i received a warning for posting the Vid showing the issue . THAT was the limit , over 2k spent on their plugins and you get treated like your nothing . Steinberg on the other hand showed willing for resolve which is the most important thing to me . 5 days after my machine broke and receiving 7 messages from AA users that were to SCARED to speak up in public AA released fixing for 4/5 of the latest plugins for guess what ’ broken Over sampling recall issues ’ .
I will not even entertain loading their software now , i want total stability , not plugins from a company that release everything at an intro price because you are beta testers .Also bare in mind AA are meant to be a Steinberg Partner which makes it a little bit more of an issue .
As you can see im still not over the heartache caused but goods came out of it , this DAW is pro setup , All crash dumps from C12 and windows dumps were checked for the issues while the new install of windows was installed . It’s flies like never before .

Ive discovered the new black Valve compressor can do most of AA stuff if you add the stereo enhancer just before :wink:


getting my 7950x made a huge difference to how many AA plugins I could use . Having the AVX instructions makes a big difference as AA seem to make good use of it.
Did i read that the current gen of INTEL CPU’s has dropped support for AVX? that might be a reason they’re not performing as well…not sure about apple silicone.


me too

Been using 13 for 1 week now. Im still using 11 (never liked 12) and the difference on the same machine just proves that the issues are with 13. Stop thinking your daw is doing something weird or your cpu isn’t good enough. Its all rubbish.

C11 runs just fine with now sudden CPU spikes. In 13, all i have to do is load up ZebraHz which is almost what, 10 years old? ) and the meter goes up all the way.

Unacceptable. A simple public beta prior to release would prob catch these major issues. Everytime i have issues, Steinberg points to “it must be some plugins” when the reality is: All plugins i have work fine in Live, Bitwig and whatever else I have. None of them even ever crashed due to one. But Cubase? God forbit. Im more than happy to beta but when I pay for an upgrade, I dont want showstopper bugs and performance issues. In 2023.

MacBook Pro M2 Max here, both Cubase 12 and 13. Very busy project runs fine if I have one or more of my VSTs record armed/enabled, but as soon as I don’t, ASIO Guard peaks and spikes and playback stutters and stops. It doesn’t exhibit this behaviour on my PC.

This is at a small buffer size of 64. If I raise it to 768 I can just about playback in the busiest parts of the track, but the ASIO Guard meter is completely full.
Again, on my PC (9900K processor) it pretty much plays well at 64/128 buffer size no matter what track I select and ASIO Guard stays calm around the 3/4 mark.

Oh and finally, if I select any Halion track, that simply makes it peak out regardless of whether it is record armed/enabled or not…

Ok, it seems Halion Sonic 7 is the culprit… disable this VST and I can even playback the project at 32 samples whilst selecting any track, record enabled or not. Is this a known thing that I’ve missed? It definitely seems very resource heavy in slightly odd ways compared to other VSTs.
ASIO Guard is still a little higher and stretched compared to my PC, but seems stable enough now.

The first project I opened in 13 tanked from measure 1. Nothing but stuttering. As a percentage, I can say there’s more silence from stuttering than there is music playing.

Interestingly, the projects from 12 mix down fine in 13. It’s just everything else.

And if I start a new project in 13, it’s fine up until I get to around 3 instrument tracks. Then it starts stuttering, again.

Ive been getting great results with my new install and C13 , even with older projects BUT the ASIO is still erratic and a little dicky bird tells me that there’s a maintenance update coming pretty soon
