I assume PreSonus decided to go with their Show Page in regard of "Live" performance.I'd try it on your computer, on my it's almost as stable or unstable as Studio One. It's usable, but Live and Bitwig never crashed on the samé laptop (I don' t remember Live crashing the last decade).
With the use of the arranger track they missed that goal by miles already. And I don't think that Presonus rewrites S1 from scratch now (with a clip launcher they'd at least have some sort of a way more usable arranger feature, so maybe they will implement that).
And they actually can add fundamental changes to their software. I watched an interview with main devs of the DAW and they said that, developing Studio One, they've made sure they'll be able to add and change anything in the future(for example, when there is a new tech, method, standart, instrument etc. in the industry). Of course nobody can tell if they were telling the truth, but I don't see any reason not to trust them(why would they lie anyway...).
