Same here, home-officing as well, a few short trips to ccrma to pick up
things or first stuff that cannot be done remotely. Not really doing
whatever I want, though (well, a little bit :-). Been working on
(trivial) stuff for our weekly streaming online concerts / jam sessions
(the "Quarantine Sessions", up to #14 this coming Saturday, see ccrma's
web site). Some SuperCollider code to "spatialize", reverberate and
control them remotely and then feed the ambisonics 3rd order mix to a
binaural decoder and mastering processor for the remote audience :-)

At home?? I imagine this was pre-covid?

Good to know. I have to re-start my measurements (curious about the
Zoom), there is just too much to do. But as I am at home I don't know if
it would be worth it (smaller rooms, so shorter ir's - at ccrma I was
down to only about 200Hz already)
