I believe there’s nothing, but I was curious about recent developments just because of convenience and curiosity since there was a very good library out there.
But thinking a bit more, several factors could impact users’ musical “philosophy”. For instance, Patterns have a significant presence in the SuperCollider, while non-real-time (NRT) synthesis hasn’t been developed in a user-friendly manner, although it could. And I remember software like Paul Berg’s ACToolBox that created NRT output for supercollider that felt like a different approach using SC. Unfortunately, he passed away and his system was not free software.
I wrote a bit about it here on Interval Algebra, and how it could be done in SC: Interval Algebra and Event Scheduling?
But those are just random thoughts. Nothing that would shift a paradigm.
EDIT: the only thing I know csound can do and sc can’t is playing SOUNDFONTS
