You mentioned the Simon Millward books - do you have the very latest one, Fast Guide to Cubase 6?
If not, I’d suggest buying it.
If I were teaching a university class on C6, I’d use the Millward book as the textbook. It’s far and away the best aftermarket manual available (and I have read all of them). Clear, easy-to-read, yet so thorough. It also includes several non-DAW specific tutorial sections (the EQ curve maps in particular are a fantastic reference, even for old coots like me.)
So maybe you don’t need a tutor? Just start at chapter one of the Fast Guide, read it slowly, and try out each example. Write in the margins too! And use a highlighter pen! (That’s what I did… just like back in college .
Seriously, it’s such a good book. Whenever I recommend Cubase to new engineers, I always hand them this book. Steinberg should include it with the software (or at least offer it in as an add-on).
P.S. Are you in the UK? If so, maybe you can contact Simon and see if he’s doing any local Cubase seminars.
