Does anyone know if it is possible that someone has written a user manual for this software?
Received my copy from Amazon today, but there is no user manual provided, only instalation.
Regards.
You will find the user manual as a link to the .pdf when you Install and open the program. It’s in one of the menus at the top. Can’t remember the name of the menu right now as I am not at my studio but… You’ll find it easily.

Hi
…it’s “help/documentation”
As well as you can download all the manuals as *.pdf from the Steinberg Homepage
