Hi Michael,
Go To Tools>Options>Audio Engine, it looks to me like you are naming your port names in a way that prevents ease of switching your audio driver.
here’s how the setup looks for my main audio device ASIO Fireface USB is driver selected
here’s how the ‘Labeling’ appears in Audio Ports, please note these ‘Labels’ because that is what they are to Cantabile. They are in the left column under ‘Name’. In the 'Assignment column you see the names the asio driver provided or in the case of wasapi the names they provide.
Here is my second backup audio interface
And here is how the labeling looks for it. Notice the Names column still has the same 'Label" names but the driver from NI gives different connection names for the right ‘Assignment’ column.
If the Name columns are the same from Audio driver to Audio driver then when they are used in your songs they become universal on your different drivers. No more rewriting routes each time. If is the case please post back and let us know in the event it is something else.
Dave
