If I open a project in N10.1.0, check that the Input and Output settings are correctly loaded in Studio/Audio Connections, and then save the project; when the project is opened in N8.1.10 the Input & Output settings are not loaded. If I then load the correct Input and Output presets and save the project in N8.1.10, when I open the project in N10.1.0 again the Input and Output setting are no longer loaded! - and so on, round and round.
N10 and N8 are both auto-loading the same project when they are launched.
