&gt; Your may well perceive variations of latency, just not on a conscious level as a delay.<p>I agree. If you &quot;want&quot; to feel it consciously don&#x27;t type text on a keyboard but play a melody on a midi keyboard. A latency of 10 ms, let alone 100 ms, feels horrible. For instance, a 1&#x2F;16 note at 140 bpm has a duration of 107 ms!<p>I find it  quite fascinating that recording midi in, say, cubase is possible at a lower latency than editing a text file in Atom.
