Existing Project and Template


is there a way to use an template on a existing project for adding ladspa plugins. fader and panning Settings?

You cannot apply a template to an existing session; You can create a template from an existing session, and then use that template (which will include plugins etc) when creating a new session.

Sadly, because the material of a upcomming demo uses the same instruments, mics and settings. And a template in such way would be nicely.
Is there a way to run a second instance of ardour and routing the tracks to the template created session?

Why not load all the material (all wav-files from the different songs) in the same session and use automation to adjust volumes and such at the beginning of each song.
