I agree!
The lack of a downloadable manual is very frustrating.

"With the new Melodyne online user manual, you are always reading the latest version of the text, as we are constantly updating and adding to its contents. Furthermore, you are not restricted to just reading the manual tours but can also watch the corresponding films as you go. That makes getting to know Melodyne much easier. And we are still working on the online manual: soon you'll have a search function, and other equally useful functions are set to follow. Look forward with us to a manual that not only helps you out but is also fun to consult! "
.... however I'd suggest this approach, while very clever, does not suit many users, and it's just arrogant to suggest otherwise; PDF, with it's built-in search function, is not obsolete!
It may work in Germany, but there are customers in many corners of the World where internet connections are still slow, unreliable, and expensive.
