The Wikipedia article on Dorico has a quote from some review:
"There are now three ‘professional-level’ notation programmes available: Sibelius Ultimate, Finale and Dorico. However, the only one of the three under significant development is Dorico."
I wonder how widely that view would be accepted? I am a sporadic user of MS, and am quite contented with what it can produce; I wonder if there is any meaning to "professional level" other than "costs money". I also see the truly bizarre illustration given on the WP page of how Dorico "supports complex musical notation", which is a particularly hard-to-read version of Chopin's Ballade number 4. I can't tell whether the special feature of Dorico is supposed to be that it can combine the stems in that odd way, or what -- in any event it is a very misleading advert for Dorico.
Can someone give a quick rundown on the actual state of currently available programs (normally spelled like that, even in British English); I thought Sibelius more or less died when the team went off to Dorico. Remember that anyone can edit WP!
