I’m also in the process of learning Cubase Elements and Pro 10.
Lynda dot com has two old courses on Cubase 7 and 8. I completed the one on 7 and am halfway done with the one on 8. Most of what was taught in those courses was still relevant to Cubase 10. Also picked up the Cubase 10, Retrologue and Groove Agent courses for a good price from Born to Produce and will jump into those next. Born to Produce also has a 6 part freebie on YouTube that introduces you to Cubase Elements 10.
