Most Daws have this. Does Cubase 6?
Save all maxer settings as a snapshot in different sections of the song. Sorry if this has been covered.
Oh how I wish! 
“Most Daws have this” which ones specificaly ?
How do they get round the clashes with the normal automation?

I think it just takes a picture of all the used automation tracks at any given point and adds a node.
Hmm seems like no one knows the daws that that have this feature.
