Having created an input transformer preset, I decided to use it in another project. I found my preset in the drop-down menu and chose it. So far so good.
Then I saved the project and closed Cubase. When I reopened the project later, the configuration was set properly, but the drop-down menu showed No Preset instead of the preset name.
This is unfortunate because the fact that I am using one of my presets is not documented in my project now. I think that when you use a preset and don’t change it, its name should remain in the drop-down menu so that you can see which preset you used.
Cubase 12.0.40, Windows 10, Surface Pro Tablet (i5)
