Marc, I not only strongly agree with you that Dorico has moved the industry, but for that same reason, I hope Sibelius will remain competitive.
While I can’t imagine Daniel and his team ever becoming complacent (they certainly didn’t when they were the Sibelius team), I CAN see any parent company cutting back on development dollars once their product becomes dominant.
A perfect example was Finale before Sibelius came along.
A funny incident today:
Today (for the first time) I tried Dorico 2.1’s propagate properties. I selected all music from my edited organ part and looked for the context menu or menu to propagate its properties (back to the score). I could not find it. Made a quick google search, used the Help Menu to find the menu item - it was absent …
Actually I had read so much about Dorico’s 2.1 features that I simply forgot to download and update to Dorico 2.1 …
