there is also control latency in this case. When you tell it to do
something, how long does it take before it does it? Will it always take
exactly the same amount of time no matter what, or can it vary when the
system is busy with other tasks? When you are trying to tap things with
rhythm, this is important. It can be very difficult to guarantee this type
of operation in a non-realtime os, like windows, macos, linux, etc. That
is
why real-time operating systems exist.
Also "any recorded sound won't have to be played back until the next loop
round" is only true in the most simplistic approach to looping. For
example, what if you tap reverse while you are overdubbing? whatever was
just recorded needs to be played back immediately or you will get a pop,
and that pop could end up recorded in the loop since overdub is on...
