RE: Repeater latency

Odd to mention that keyboard musicians are more tolerant to latency
than guitarists or
drummers are. I suppose there are quite a few keyboardists out there who
do a lot of textural
pad-like sounds. For me, the attack of a note is crucial. Many
manufacturers get a lot of
interesting sounds when they forget about the attack. Few of them really
get the attack right
even when they're trying. Emu comes close. Kurzweil comes much closer.
Even though MIDI was developed in the beginning with keyboards firmly
in mind, it is
extremely lacking in the latency department. Ever try to layer 4 sounds
together and then hit a
simple 8 note chord? Talk about latency... Somebody's bad idea of an
arpeggio joke.
Ok, enough MIDI bashing. I'm curious about Kim's statement that 12.5
ms is a "particular
distance". I never thought about it in these terms. Of course it makes
so much sense. If I am
on a stage and I'm hearing my sound delayed by 12.5 ms, my body will
interpret that as being a
"particular distance". So how far away is 12.5 ms? I know that it's
really simple math, though
I'm unsure as to how much of a second is a ms. Is it .001? If so, then
the perceived distance is
a little over 14 feet away, or 4.3 meters (assuming 68 degrees F or 20
degrees C). Huh, I guess
this puts things in a perspective of sorts. I try to keep my onstage
monitors about 4 feet away
from my head, and on the same plane (3.5 ms latency through the air). To
this end, I am running a
pair of active studio monitors and placing them behind me. Since I'm not
using a live mic, this
works very well as monitors, and in smallish places, as PA as well.
Now, was this latency test done on Repeater version 1.0? If so, what
is the current latency?
I always run my keyboards through the Repeater on dry mute, mostly
because I can't stand how much
the sound degrades when I mix pre-Repeater and post-Repeater dry signals
together. This is both
the latency thing (phase shifting) and just that the signal has gone
through yet another A/D,D/A
process.
This also makes me wonder what the latency on my keyboard is and
whether I'm unconsciously
adapting for that (more than likely). There is also latency on a grand
piano, and great latency
on a pipe organ. And I'm always late to work...
