External Effects / Audio Connections have been talked about quite a bit, was hoping to see it improved myself in V11 but tis not the case.
Why Why Why can I not save my External FX Routing? - Cubase - Steinberg Forums
And again…External Effects - Cubase - Steinberg Forums
just to list a few
Anyways, your External FX should not be resetting/clearing every time you start a new project.
do this test for me just to be clear and reduce what is maybe going on.
1.) Start a completely new fresh empty project not based on a template.
2.)As a test, route a few of the external fx how you would want them (just do a few as a test)
3.) Save this project.
4.) Close this project and Cubase.
5.) Restart Cubase
6.) Again, start a completely new empty project
7.) Are the External FX you routed still there?
