I have saved 6 tacks with a different VSTi on each…all routing to a group channel. I selected all including the group channel when I saved the track preset but when I reload this track preset only the 6 instrument tracks are recalled and NOT the group channel.

Is it not possible for Cubase to remember to recall the group channel?

Ok I see now the method is to use the track archive facility to save and reintroduce multiple tracks to a new project.
