Crash with Nuendo 14.0.32 when using SpectraLayers Pro 12.0.30.431

Had a small project with two audio tracks.

The 2nd track contained a song with 4 instruments (guitar, drums, bass, piano) and one vocal track. This track was activated to be edited with SpectraLayers.

Selected in SpectraLayers “Song entmischen” (en: “de-mix song”?).
After about, let’s say, 30 seconds, the computer screen froze for a minute.
Mouse movement/keyboard not usable.
Then Nuendo crashed, and I could again operate the device (use mouse, keyboard).

CPU: Intel Xeon E5-1680v4
Mainboard: Supermicro X10SRi-F
DRAM: 4×16 = 64 GB ECC RAM
SSD: Samsung 870 EVO 4 TB
GPU: nVidia RTX 4070
nVidia Driver 576.88
Nuendo: 14.0.32
SpectraLayers: 12.0.30.431
Recording Interface: RME HDSPe MADI FX, HDSPe FX driver v 2.27
Windows 10

Had the same problem. Roll back to the previous version of SL.

Also happens with SL11.

Not what I meant, rollback to 12.0.2x.

How is it possible to downgrade?
With the Download Assistant I didn’t see this older version.
And when looking at the Webpage they only offer the latest version.

Sometimes you can click the arrow beside the instal or re-instal button and you can choose an older version. To re-instal 12.02x I just checked my Steinberg folder in my Downloads folder and the older installation file was still there. Win 11.

Try here:

Well, that was, of course, the first place I checked. And if you had looked there before, you would have seen that this isn’t the solution, as only the latest version is available. Or am I missing something?

Unfortunately, the old FTP server no longer exists; everything now has to go through this — also the one you referenced — download section on the web server. Am I missing something? At the moment, it appears that you actually have to open a Steinberg support case just to get access to the previous one or two versions.

Every company knows that software is not bug-free and that not every issue can be fixed immediately. Therefore, it’s only logical that a fallback to an older version should be provided. Nearly every vendor does this, or at least offers a quick alternative download location — or allows users to tweak the URL to access older builds.

But this approach is not user-friendly and only creates unnecessary work on both sides.

Have a look at this post in the SpectraLayers forum which addresses a similar issue and provides a special build 12.0.31.432

Many thanks, will try that.

BTW, the older version 12.0.20.426, which I got from a friend, works also well.

I will uninstall 12.0.20 now and try the later one (12.0.31.*) as proposed by you.

Many thanks for this information; very kind from you :slight_smile:

This is the outcome of testing SpectraLayers 12.0.31.432.
I compared it with the older working version EDIT: 12.0.20.426.
The issue with 12.0.30 was, that it crashed.

The new version 12.0.31.432 does not crash, but is much less efficient working as you can see in the snapshot of my Excel file.
To unmix all instruments from a song of 05:15 mm:ss length, it takes more than double as long compared to 12.0.20.426.
Also significant for the new version is, that the CPU consumption raised much and that only the main cores are being utilized, the hyperthreaded core only to an unusual low degree. Whats really a bummer, the GPU does not seem to be utilized at all, nearly 0.
Something is loaded into the graphics cards memory, but its also only 82% graphic memory allocation compared to 100% usage in the old version.

All in all, nice that it doesn’t crash, but it looks as if the performance is completely down and the GPU is doing nothing.

Another note, if I start the unmixing and then immediately try to stop,
then in 12.0.20.426 nothing bad happens. If I try this with 12.0.31.432, then it crashes Nuendo.

I believe it was reported that it wasn’t consistently using the GPU even when it was selected. This is another reason I rolled back to 12.0.2x. That version works fine for GPU.
