UDP was originally chosen because OSC was meant to replace MIDI for
performance controllers like keyboards and all the new keyboard/neck like
controllers out there. At 100M net speeds tcp would show timing issues.
There are now better ways of doing things and faster networks. For mixer
control, tcp would be better because surity of message delivery is more
important than speed.

There are other control solutions out there that might be better than OSC
because they are more firmly suported.

OCA which is now AES70... and so no longer free to look at... though of
course free to use. OCA is a two way protocol from the start and the
controlled device is supposed to give the controller enough information to
create a controller (on glass anyway) on the fly. It has more of a
standard way of talking about controls.

There is muscle https://public.msli.com/lcs/muscle/index.html which is
used by Harrison Console in their digital consoles

both use a path like structure

So long as there is an amazing choice of standards, it will take a long
time for OSC physical knob controllers to show up... the Wing is perhaps
proof of that. OSC 1.0 made it out the door, OSC 1.1 has gotten lost and
was never finished and OSC's main site is effectively static. I think
sendosc, touchOSC and Lemur seem to be all that keeps OSC alive. Maybe the
Wing will change that in the same way the Mackie Control did (almost 20
years after OSC 1.0 was released).

Hmm, I just took a look at http://opensoundcontrol.org/ and it seems
things are worse not better. The OSC 1.0 spec now points at
https://web.archive.org/web/20030914224904/http://cnmat.berkeley.edu/OSC/OSC-spec.html
There is however a pointer to the sugestion of what OSC 1.1 might have
been: https://zenodo.org/record/1177517

So http://opensoundcontrol.org/ is now just a rough few lines that point
at some archives. OSC is still alive only in the libs and the SW that uses
them. This is maybe enough as OSC has proven useful enough to stick around
anyway. That anything has been done on the http://opensoundcontrol.org/ in
the past year is perhaps a sign of hope.
