I have installed Trilian on Windows 11, using the "Spectrasonics Trilian v1.6 Factory Library [STEAM]" release. I followed the instructions, running the software updater and then the keygen to activate it.

The code from the keygen seems to be accepted, and when I click the Continue button in the Trilian app I am told to close and re-open the instance. But when I re-open it I get taken back to the Authorization screen.

If I select a Trilian instrument from the Omnisphere UI I get this error:
"Cannot load SoundSource "Bass Station Unstable Square" in Directory "Trilian Library". Try refreshing index in Browser."

I've tried clicking the Refresh button in the browser but it didn't help.

Any ideas??

 

Sounds to me like the patches for the plugin have not been properly applied. The NFO/install notes for the Trilian plugin you also installed should include a list of where to place the patch files. For my install there are 3 locations. 2 for the vst, and 1 for the standalone.

For authentication, in my case, both Keyscape and Trilian were authenticated at the same time Omnisphere 3 was. I didn't have to do each plugin separately.

 

The README for the release says:
"Place the «Trilian» folder to «C:\ProgramData\Spectrasonics\STEAM"
...then run the Software Update. Which is what I did.

I can see the Trilian library and instruments in the Omnisphere UI, but it's when I try to select an instrument that I get the error.

I've just tried installing the "Spectrasonics.Trilian.v1.6.6d.Incl.Patched.and.Keygen-R2R" release on top of it, but am getting exactly the same problem.

 

Adding another release on top of an already buggy install won't make it better.

Did you get your omnisphere install authenticated and working properly? If not, that will impact any other Spectrasonics plugins you try to install. As I wrote above, the authentication for Omnisphere applies to Keyscape and Trilian (assuming they are all patched correctly).

 

Yes I have Omnisphere 2.8.7 authenticated and running, and can access my Keyscape instruments. It's just Trilian that won't play the game

 

Did you check the permissions on the Trilian folder? The error you first posted sounds like it can't actually access the Trilian related files in the STEAM folder. Compare the permissions with your Keyscape folder/files.

Also, if you hit the logo on the interface, it returns to the splash screen, where you can hit the diagnostics button. Make sure you have the right locations showing there, and if you can't tell then screenshot them.

You can also try the old trick to move, rename to BAK, or delete the zmap file which forces it to rebuild the database.

 

Permissions on the Trilian folder (in STEAM) are Full Control for all users.

Which of the zmap.index files should I try deleting? (there are quite a few):
