I switched from Finale to Dorico about a year ago. It was like night and day in terms of user-friendliness. Finale felt heavily loaded down with legacy garbage. On Windows, it (really the Aria player) insisted on complete ownership of my audio output, too, which was a real pain.
> Finale felt heavily loaded down with legacy garbage It seems like the letter fully confirms & validates your feeling. ;) There’s just no GUI software started 35 years ago that’s still alive and feels modern and unbloated. Okay, there might be something, but I want to see the examples that prove me wrong. Things that come to mind are like Photoshop or Word, both bloated with legacy and might be dying to web apps. Or…
I'm sure there's a lot of old niche software that feels modern and unbloated. Nuke[1] is 31 years old and Houdini[2] is 27. Maya[3] is 26 years old. I would say Maya feels bloated--but at larger places I've worked, people have avoided the newer viewports with more features because the "legacy" viewports are so fast.
It may be hard to make it feel "modern," but I love how optimized "old" code can be if they've been able to resist rewriting it.
