Why does Cubase 7.5 come with GA one AND GA SE

As title suggests, why does it come with Groove agent ONE and SE?

Cheers

I guess to be compatible to projects from previous versions.

Yeah - you dont want to try loading an old proj. of yours in 7.5, only to get an error that a native plug cant be found.

Thanks, which one should I be using. I’ve been using ONE with success until I realised I also had SE.

Either I guess, whatever works for me?

GA SE has many more options and functionality. In my opinion, theres no reason to use GA One anymore, other than loading old projects. All my new projects are GA SE and/or Battery 3. Again, this is only my opinion.

The same opinion goes for Halion One. Halion Sonic SE is sooo much nicer.
