Any digital instrument also has latencies. Basically it is a matter of
playing the instrument you are using.
How are you measuring the latency?
with a digital instrument, in this context, it has to be from the time the
gesture is made that controls the effect, till the effect is heard by the
BTW, not to overstate the obvious, but...
A good way to measure total latency is with an oscilloscope. Hook up one
probe to the mic, the other probe to a wire coming out of an output on
your device. Then make a patch that sends the sound straight through, eg:

Also, for an electric guitar player, the difference between the latency you
get with an analog amp (not perceivable) and a computer with more than
10(?)ms latency, is very big. Maybe around 10ms would be "ideal", but
haven't reached that (yet?), but would really love to.

well, i play a lot in an orchestra. (doublebass) and i can assure you it’s a
problem you don’t get used to. (and that is not just me) sure you can adapt to
the situation but it is not ideal. let a pipe organ player play with a
conductor and orchestra and the fun begins :-) it works but it needs

I guess I don't get that since I've been playing that relative latency for
years. How is 10-15 ms not "real time"? It's not even really perceivable
unless you're doing lots of high rate short attack& decay stuff. At least as
far as I can tell. I must be slow.

No, it's the amp to ear, related to speed of sound in atmosphere
(around 300m/s).

We could do a patching circle/UDOO setup afternoon :D

H iSimon -
I haven't tried any but the built-in yet but I have a few USB interfaces
around here that I can try. I'm about to go on an intense trip but should
be able to do some tests when I get back, assuming nobody else has figured
this out first.

hey list,
does anybody that uses an udoo board have any recommendations on a
usb-soundcard? should be very compact.
i tried a cheap one from dx and i could not get any good results (loads of
xruns even with periods 3 and 1024 and up frames in qjackctl) this is on the
ubuntu version from udoo.
