Hi quietbox,
On Arturia's Homepage at the top center there is a button called 'Downloads' . When you place the cursor over this button a dropdown menu is displayed. Click on 'Manuals'. In center of page is a list of all the products. Click on 'Keylab' and at top of new page is a list of Keylab manuals in different languages. Click on your preference of language and the Keylab manual loads. Save this in you favorite fashion. I saved to my desktop. I, also, downloaded and saved the manuals for Analog Lab and Analog Factory.
Peace,
Steve
