Ok… I got it to work… … Thanks nia_y27 !!! Now I also discovered that if you know your basic XML… its easy enough to add other documents … whatever you want … as long as the entry in help_url.xml is pointing to the right location:
Here is a snippet of additional help menu items I added… All of which open the appropriate manual on my MAC. I should mention that its probably a good idea to save a copy of this file in an alternative location… along with your documentation… because the next time you run an update to Cubase … The help_url.xml and all additional folders will be removed and replaced with the default directory… and if you saved your docs under “documentation” folder within the Cubase installation folder… All those Docs go bye bye! ( I belatedly discovered this when I updated to Cubase 9.0.20!)
In the future, I’d like to see Steinberg put in a script that will search for a documentation folder and just add the entries to the Help menu. It wouldn’t be a very difficult script!
