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.
