You are aware of the fact that there is a full team of people (aka the former Emagic crew and more) are working on Logic? Honestly I cannot see how things should go faster, because in my opinion Logic updates were pushed out very frequently during the last 1.5 years.
Maybe the old, full team is still there, I wouldn't know, but I'm sure most of them are still around, and others too. I'm not saying that there isn't a team working on Logic - the last update certainly proves that there is.
But in terms of "I cannot see how things should go faster": it's a question of priorities. Cubase had, for instance, expression maps almost 10 years before Logic got their Articulation Sets. Steinberg and Avid have had a dedicated staff working on notation only for a long time; Avid took over Sibelius in 2006, Steinberg took over the original Sibelius team about 5 years ago - while *many* of the wishes I and many I know have had for Logic since before Logic 8 was released still aren't implemented. So it's not about "how things could go faster", but about what kind of priorities Apple has for Logic.
Don't get me wrong, I'm not one of those "Logic is dead" guys. We certainly have seen some nice stuff since the Logic 8 days. But it looks as if Apple has a rather extreme lack of interest in composition related features and the situation of composers in general (since they mention all kinds of stuff about a piece when listening to them - except who wrote it).
Things have gotten a little better lately, but the thing about not mentioning composers etc is something which should have been in there (in iTunes) from day one.
Having said that, Apple is extremely successful when it comes to making money, and I respect them for that. But they're not the company they were, they're a mainly a phone/car/watch/"post PC" company.
One of the reasons why they have so much success is maybe the fact that they ignore/postpone the kind of wishes a small group like composers and VI users often have, and go for what most people want: entertainment and 'pop culture'.
Logic is soon 30 years old, but is still missing solutions for wishes like multiple automation lanes in the editors, ability to move channel strips in the mixer, a customisable colour palette, a lot of score functionality, full freeze (which unloads samples and other RAM), a separate unload function doing the same (important for large templates), proper track naming (as opposed to channel strip naming), proper display of accidentals... and much more.
Some of the stuff I personally miss the most are some of the composing oriented features Sibelius has had for a long time (which Dorico, made by the same team, doesn't have either). So I'm not saying that there are someone out there who does everything/most stuff that's important for users like myself right. I just wish there was.
If almost 30 years of development without all these functions is 'fast' for you, at least one of us need to redefine how we use 'fast'.
When Apple acquired Emagic, they had maybe around 10 000 employees. Now they have more than 120 000. Maybe 50 of these work on Logic related stuff? Whatever the number is, I think the staff should have been large enough to give the kind of users I'm talking about more attention.
