Matt Vanacoro has reviewed Dorico for Ask Audio (the same review can also be found on MacProVideo and a few other sites), and he says:
Dorico is a real life ‘if I had to do it all over again’ moment for a software development team, and I think it will definitely speed up the workflow of most notators. I’m a huge fan of the speed, ease of use, and workflow enhancements of Dorico. I’m excited to see where Steinberg takes it next.
