Cubase 15 Pro: Spectral Separation / Stem Separator option missing (Win 11 25H2)

Cubase

Hi everyone,

I’ve recently updated to Cubase 15 Pro, but I cannot find the new “Spectral Separation” (Stem Separator) feature in my menus. It doesn’t appear under the Audio menu as expected.

Here is my setup:

OS: Windows 11 Version 25H2

CPU: Intel Core i7-12700H (12th Gen)

Version: Cubase 15.0.6 Pro

I have checked the Audio menu but the option is simply not there.

Is anyone else experiencing this? Could it be related to the Windows 25H2 preview/update or a specific hardware conflict?

Thanks for your help!

looks pretty straight forward. never used this feature myself. do you have the pro version? it most certainly is present in my Cubase Pro 15

I’ve followed all the steps correctly, but I still don’t have the option.

hard to say. are you sure you have the pro version active?

Upgraded to 15 from 14 pro

Same, and I don’t see this feature anywhere in the product. It’s literally the only reason I bought the upgrade today, to separate stems. And now I can’t. Makes no sense.

That’s cuz you have no track highlighted (from what I see).

You sure you first highlighted a mixed track? The prompt won’t appear in the menu till you do.

ME TOO,SAME PROBLEM :persevering_face:

Do you own Cubase Pro?

13

yes .I think that the problem is the operation system ,using os Mac Monterey :man_facepalming:

Same OS here, just gone to try it out and there is nothing in audio for stem separation. Looks like the minimum OS is literal on the specification for this to work, so you’d need Sequoia minimum.

Same here on Windows (updated). Using Artist 15

Not every edition of Cubase offers the feature. Which one do you have?
