Well i didn’t go through all posts in this thread, but just to make sure u do the right thing.
to move “VSTi outputs” channels in the order u want to show up in the mixer , u should move those outputs up or down from project window inside the vsti instruments folder. inside that folder u can move vsti folder up or down or move specific output channels of the vsti in subfolders (those who have the keyboard sign next to them).
** maybe there is an option in preferences to synch mixer and project though, (im not next to cubase right now to check)
