Thanks Len for the useful feedback.
I was going to say 10ms is about where I start to feel
disconnected from
what I am playing, but I realize I am thinking one way and round trip
would be about 20ms. So 16ms might be well workable.
Psychoacoustic tests (many of them from the CCRMA SoundWire team and
others) shows that 21-25ms is acceptable to keep a steady tempo. Larger
values make the performers slow down, very low values make them accelerate!
AFAIK in musical instrument design the 10ms figure is taken as a threshold
for your instrument response (e.g. keypress --> sound), but in performance
the values can be higher as said.
Your inputs are interesting, and yes, I think AES67 could be the first step
towards integration.
More soon...
