Cubase 15 not supporting many VST3 on mac

I’m just trying a demo of Cubase 15 (I’m currently on 14). A huge chunk of my VST3 plugins are not supported. Including current versions of Spitfire and many others. Is this a bug or would I just loose all of those plugins? If so there a list of unsupported VST3 plugins?

Thanks for any help on this.

Cubase IS the VST Standard. If you’ve got plugins not working in it, it’s likely something to do with the plugin or your installation.

I have 181 licenses active on just my iLok and all of those plugins show up and work in Cubase. That’s not counting the ones that don’t use iLok that I use all the time like TAL synths and Audiority plugins.

What exactly do you mean by “not supported”? Do they end up in the Plugin Manager’s Block List? If so, you can try unblocking them. For most plugins, that actually works quite well in my experience and doesn’t necessarily mean the the plugin crashes and whatnot.

I am on 14 and only tried the Demo of 15, I cannot remember masses of plugins being blocked or having problems. In my experience maybe a couple of plugins can make problems with a new Cubase version, and usually updating them to the newest version fixes that.

It says “Unsupported Architecture (x86_64)” and it puts them on the blocked list.

Some Softube, PSP, Plugin Alliance, Spitfire, Nugen, Kazrog etc…

Are you on Windows or Mac?

More specifically: on Apple Silicon (M1…)? Then, unless Cubase is run in Rosetta mode, it cannot use x64_64 plugins. Best to install the Silicon native versions of the plugins.

Running in Rosetta will allow old plugins to work and there will be no noticeable performance hit as well.

I don’t have a Mac, but I guess that the above mentioned plugins should all have native versions by now, so maybe no need to use Rosetta anymore?

So not VST 3 plug-ins then.

no, VST3 plugins can also be “unsupported architecture” (see above Mac/Rosetta).

you’re likely installing more than 1 version of the same plugin and getting the error about the 2nd version, or something. Can you actually insert the plugins you want?

Unsupported architecture (x86_64) means the plugins are Intel while Cubase is running natively. All of those developers offer native VST3 versions of their plugins, I’d start from checking if they are up-to-date (I’m a customer of 5 out of 6 and run everything native since 2022).

I’m not 100% sure which (or if it applies at all here), but I remember some installers offering to either install Intel or AS, meaning there is no universal binary and one needs to choose when installing the plugin.

:joy:. Did you even read the title of this thread?
