I don't know of any human endeavour that requires lower latency or
more precise timing than music.
A friend used to work on set-top boxes, with fairly slow hardware.
They had demonstrations of two different ways of handling
inability to keep up
with the data stream:

Potential customers always thought they wanted the first approach,
until they watched the demos. Human vision fakes a lot of what we
"see" at the best of times, bit hearing is more sensitive to
glitches.
Having the ears being able to hear millisecond differences in sound
arrival times is key to our ability to hunt and evade predator's.
Not only that, but the slight non-sylindrical shape of the ear
opening 6 canal cause _really_ minute phase shifts, but they are what
makes it possible for us to differentiate between a sound coming from
directly behind vs directly ahead.
While our eyes have a time constant closer to 0.1 seconds.
That is, I blame natural selection on the above.
Supposedly, we devote more of our bran to hearing than to vision?
