How else could you represent piano roll data than as a stream of events? I thought that was ubiquitous since the invention of MIDI.
Are you saying other sequencers are unable to render the same data as piano roll and score?

And on the notation-oriented side, you have things like MuseScore, Finale, etc. where there is an event model, but the UI itself doesn't have mature (or any) support for tracking mixer/knob automation (outside of what can be derived automatically from dynamic symbols).
Years ago, I used Logic in a musical theater context where I could build a constantly-updated demo for pitching/rehearsals/live-iteration and edit the final orchestration to be printed for the pit orchestra, both from the same living document. Could I have duplicated my changes in a DAW and notation software separately, and kept them in sync manually? Absolutely, and many creators do. But there's something special about having that holy grail at your fingertips.
Cubase, surely? I'm pretty sure it has done this for decades unless I am misunderstanding what you're saying.

I'm still a Logic Pro fan, but credit where credit's due!
