Craig you are right on this 100%.
Here's the thing though... I use 3 different daws and a supplemental notation (sibelius) program that I also modify to be more functional with midi. With 2 of my 3 daws, steinberg is the lead in development of the standards those daws use. these daws are sonar (my primary) and cubase (my secondary) -- the third is reason. I think what a lot of people are failing to realize is that you have a company which developed fundamental standards that most daws use (asio and vst) forces everyone else has to adapt and catch up to. I literally think that people sometimes gloss over the fact that vst3 was under development while steiny was also working on ways to integrate that standard into their own daw and synths, putting every other developer and competitor literally YEARS behind the curve - I don't think Native-Instruments has released a single vst3 at this point and they are one of the leading players in the field.
I use Sonar for most of my work. I use cubase for detailed specifics that I can't get in sonar (like per-note vst3 expression - even though i think that their editing scheme is way too convoluted) and vst connect for collaborating with some folks on the other side of the globe - that was honestly the only reason i bought it. I also use it for their staff view quite a bit because their expression maps are easy to use.
With platinum I am going to be using mix recall a whole helluva lot I can say. Do I use staff view in sonar?? On almost every project. Does it usually suit my needs? pretty undeniably. Would I like to see it updated? yes, but I also see we're on the downslope of technological advancements right now and sonar is about 2-3 years ahead of the other major daws on the market that are based on the standards defined by a primary competitor.
I really think staff view will be updated at some point, but like i said in a prior post is that when cakewalk does it it will be done right.
I would prefer first vst3 per-note expression because I think cake would develop something that would be much easier to use than cub***. Some more ARA enhancements would be good as well.
In the next couple of years I would be expecting steinberg to have a major overhaul of notation since they hired daniel spreadbury and his team. This can be seen as nothing less than a competitive advantage.
What I do know is that in 2 versions sonar nailed vst3 and ara and are applying ara specifically in very useful ways.
So, on the downslope predict what your competitor is going to hit next and meet them full frontal with a better solution out of the box.
