Midi Connections Get mixed up when Changing Between Projects

Cubase 8.0.35, windows 10

Open First Project (activated by default) [11 vienna ensemble connections]
Open Second Project [Roughly same midi setup]
Activate Second Project
Activate First Project

Midi connections in first project don’t ‘remember’ - that is all the midi instrument and channel listings show up in the inspector but some (not all) of the instruments are routed to the wrong midi instruments and channels.


Thanks
