It is great that Presonus has continued to update Universal Control. But I can't find a manual that describes the functions and proper set up, and the manual for my interface (Firestudio project) is from 2009 and refers to settings and choices in the menu that no longer exist while ignoring all the new ones. Universal control *needs* it's own separate manual somewhere on the site twhere it can be found (like by typing "Universal Control" into the search box, which was useless for me), and it would be nice to get an update to the product manual that reflects the changes that have been made. Because I now have a "low latency" choice under safe mode that doesn't seem to be described anywhere and exactly how the various settings relate to each other are very difficult to understand without any documentation at all.
