Since the revamp of the Steinberg website and the introducton of the Steinberg Download Assistant I can’t find the Cubase demo projects anymore. They used to be alongside the patch updates, along with the manuals. The older versions (8 and 7) still have the installers, updates and manuals, but the demo projects are gone.
I probably* won’t lose any sleep over this, but sometimes I get nostalgic for such hits as “Put The 5 On It”, “Live Forever”, “Eight Good Reasons”, and more. They are in fact very good learning resources – you can see how someone else approached the production, as well as showcasing the new features of each release.
(* definitely won’t)
