Yes, I'd also be interested in more detail on that subject (being a
musician and having dont some VST programming in my time).

To all who're in LEWG: std::hive has been scheduled for a telecon on the
13th of December, 12:00 to 13:30 Pacific time. If you're able to attend
that'd be great. Thanks to all those who thrust their heads above the
surface in the mailing list to request this be discussed for C++23.
