Hi I bought a Lexicon Lamda sound card with cubase LE. Now I have two questions: I learned to use cubase in school. We had Cubase SX. What is the biggest differences between the versions, you think? I only use my cubase for home recordning and mixing. You think there's functions I'll really need that I can't find in Cubase LE? I have lots of old cubase projects that I had looked forward to remix, but my Cubase LE can't open Cubase SX - files? Is there any way for me to solve this problem?
