When I work with MainStage there is no issue to connect with VEP5 on my Mac Pro ( Ethernet ) and my Mac mini 2012 ( Localhost ).
But when I quit MainStage , he disconnect properly of my Mac Pro but NO DISCONNECT instances( preserved and decoupled ) on My Mac mini on localhost !! I have to force to disconnect all my instances of VEP5 on my localhost !!
Same issue with a friend who as a Macbook Pro on localhost and a Mac mini on Ethernet and it is reproducible !!
The only solution I have found is to save my concert of MainStage when I quit : when I do this, it disconnect properly all my instances on the two computers.
I think this is a bug, but MainStage or VEP5 ?? Thank you for answer at this issue.
