I won't discuss your arguments, because they are all true. What I wanted to state is that for us, classical composers who only work with entering notes and the necessary midi editing, the possibilities aren't anywhere near the fantastic possibilities of audio editing.
I'm a longtime Notion user and a Studio One user for 3 versions, so I know exactly what works fine and what doesn't in my practice. You don't hear me complain, because other DAWs have their flaws as well. (I used to work with Logic Pro X also.) But in Version 3, you wouldn't want to now how many crashes I had when working with Vienna Ensemble Pro and MIR Pro. Even without VE Pro, S1 regularly quit for no reason known to me...
I remember experts telling years ago that the days of traditional midi were over. Now, 20 years later, we still work as if nothing has changed. The only difference are the instrument libraries being much more realistic and sophisticated and therefore more demanding.
Some useful suggestions for traditional composers who want to create a decent mock-up of their scores: better humanising features; automated tempo changes (has improved in version 3), but can be made a lot more fluent by drawing or using a slider; insertion of key switches from an editable preset series, adaptable to all instrument libraries like some sort of graphical interface; an exact import of midi data from a Notion score which doesn't work properly now (sometimes it's a real mess); correct midi rewiring in both directions; (Notion-)score image following the piano roll when editing in either the score or in the piano roll; understandable names for CCs (not like dummy1-12-23) when editing sound patches - the common ones are present, like volume, velocity... VSL says that there are so far no exchanges between Presonus and Vienna, except for some minor presets in Notion. That's the reason of the many crashes (so they say).
These are only some suggestions. Older suggestions in Notion (like playable mordents - multiple feature request - have never been realised). But the audio editing functions are really miraculous and improve version after version. Do you understand my point now? A DAW works in two directions: audio AND note input. In my case, I hardly ever work with audio...
For the rest, only positive comments. It's a great DAW and I wouldn't want to work with another one, but I do hope that they will take into consideration the note-bound composers.
