If you're looking for low latency, than you're propably looking for the
Linux rt-kernel. The generic kernel already does low latency very well,
but the rt-kernel can be a level higher.<br>
<br>
Don't know how much the hardware is relevant to the choice of a distro,
other than that of my own experience with NVIDIA graphic cards, in
which case I've come to believe that NVIDIA works easier on on "Ubuntu"
RT-kernels than on much of the competition, unless you compile the
kernel module yourself. Specifically in RT-kernels the difference may
be striking.<br>
<br>
I've tried Fedora withPlanet CCRMA, last autumn (on Pentium 3 and AMD
Sempron), but had to give up after loosing two harddisks at once (on
the same machine). I seemed to have problems with something to do with
no=acpi, or something on that road (I'm not a wizard at these things,
as you may have gathered). I made some extensive research on the
subject, but the solutions given on different forums were not enough
for my hardware, at least. Shutting down didn't work very well. Often I
had to use the Power button to shut the whole thing down. This was on a
clean Fedora + CCRMA system, with no other additions other than: <br>
a pci usb 2.0 card (which may have caused the problem due to IRQ, if I
understand correctly)<br>
a pci m-audio sound-card<br>
and a pci wireless network card.<br>
<br>
Puredyne uses the "Ubuntu" RT-kernel, to my knowledge (it's been a
while since I updated that machine),<br>
That is the system I use as a "production machine". <br>
The pre-installed Pure Data did not work for me. Neither on the 32 bit
system or the 64 bit system. The input sound was not right (distorted,
wrong samplerate, somtehing like that).<br>
However, the daily build of pd-extended (at this date being the release
candidate 5 (rc-5)), works perfectly. And the Ubuntu RT-kernel,
together with the minimal Puredyne, XFCE desktop is a dream for the
live musician.<br>
It "just" works for me.<br>
At home, when "rt" is not as important, but easy desktop-use is, I use
the standard Ubuntu (though not crash-free).<br>
<br>
Can't find a straight answer to which is the best system. I haven't had
stainless experiences with any of them.<br>
99% of the time, though, I prefer Ubuntu-based systems.<br>

trying out Ubuntu (or whatever) and finding out that i won't work
properly on your machine. I tried at least three different distros of
Ubuntu and Pure Dyne before i installed Fedora. I don't believe anybody
can tell for sure which distro will work fine on your computer, but
there has to be one. Just be patient! <br>
<br>
(Slightly off topic) Just in case, i'd recommend downloading and
burning Gparted Live and Super Grub Disk before you start experimenting
with various linux distributions. They'll come in handy when it comes
to formating your linux partition and accessing Windows again. <br>
Also, when you have a linux distribution installed, first thing you
should do is download and install the realtime kernel (when available),
and then try JACK to see what the minimal latency is. If it's not way
less than in windows then there's something wrong. Then download,
install and run Pd, and make sure it works normally (it didn't in
Ubuntu 9.04 on my laptop). <br>

guys, i'll definitely be looking at your suggestions, i think it's
pretty clear that i should make the move to linux, but i just haven't
gotten to it. i already have an acer netbook, but the issues there are
horrifying latency and breakup of the sound (at least on windows),
pierre's solution seems like my ticket for now, as i don't need to have
the system on me. although the bisquitbox, audiopint , beagleboard
,etc. seem like good possibilities.

I suppose that by "exclude" you mean you want to avoid interacting<br>
with your laptop directly?<br>
<br>
I don't know what platform you are on but you may want to consider<br>
using a netbook. It gives you more power than a beagle board, you can<br>
develop/test your stuff right on the thing, it is small and you could<br>
even fit it in a small backpack that you could carry on stage. If you<br>
are familiar with linux you should search linux-audio-users list for<br>
some info about getting it done. Ivica Ico Bukvic (who is also on<br>
this list) does a laptop orchestra with netbooks running linux, Ken<br>
Restivo uses an eepc for live shows as a softsynth and DSP (IIRC) and<br>
I was recently involved in a project where a mobile setup with<br>
netbooks, speakers and microphones was used and carried by musicians<br>
in backpacks:<br>
