Yes of course - no problem.

Yes, I've performed in latent environments too and I know how it feels
to adjust to the latency and play the music in time. But it can
interfere with the flow especially of fast-and-improvised music in my
experience (personally and observing other beatboxers). So that's why,
for my kind of music performance, I find low latency to be important.

The more general point I made was that latencies tend to cause
performers to slow down. ``Chafe et al. measured the effect on
ensemble tempo for a simple rhythmic task when performers were
separated by various latencies (as in wide-area networking); they
found significant deterioration around 20 ms one-way latency (Chafe,
et al. 2004)'' (quote is from Wright 2004)
