It's not that bad. I tested about 20 cards for a magazine, most of
them worked plug and play. All M-Audio USB boxes I tested, didn't work
well or at all, that's why I don't recommend M-Audio USB (I still own
a Quattro which I need to sell.) I also didn't like the Soundblaster
cards. But most others were werking just fine, including most Edirol
devices, the Tascams, the two Terratec cards (I now use a Terratec
Aureon USB and a Evolution UC-33 midi interface) and lots of others.
I didn't run real latency tests except lower the Jack period size
until it crackles. I could go as low as 128-256 with most cards. This
is audio latency. I didn't test Midi latency but USB is way fast
enough for Midi.
USB is no way horrible for audio. It's far from perfect, true, but
generally it just works and it's the only choice in its price range
unless you go RME. Did you look for PCMCIA cards once? There aren't
that many (I know only RME and VX-Pocket.)
Ciao

Hi List,
This may be somewhat off topic, but I figure some of you may well know
the answer...
I'm trying to set up an audio server to connect to my home stereo, and
have been looking for an app with the following features: web based
interface for playlisting, and playback through local sound card.
I've found plenty of options which provide streaming, but none which
play through the server's own sound system.
Any pointers would be welcome
Dylan

Hi,
i just wanted to let you guys know that i created a small wiki page
which tries to collect information about how to achieve low latencies
for audio work on linux 2.6.x systems and related topics.
http://www.affenbande.org/~tapas/linux-2.6.x-ll.html
If you have interest in the subject matter, please check it out. Plus:
It's a wiki page, so if you find errors, please correct them (i'm sure
there's plenty since i'm myself not 100% clear on all the issues). If
you think content is lacking, please add it. If you wanna discuss some
part of the wiki before making changes, please use the Feedback and
discussion page..
Have fun,
Flo

Something that helps to is to never remove your known working kernel
entry from your bootloader, and make your new kernel the secondary
manually selected kernel on your first boot. This way if your kernel is
hosed for some reason, you should always be able to recover your system
with minimal pain by rebooting into your default working kernel.
later,
Steve

the first time will take a few hours to get it right (tops), but by the time
you're done, you know exactly what you're doing. i can configure a kernel
from scratch in about 20 minutes... and i'm not a hacker or anything... i
just know what i need. i'm not saying everyone should build their own
kernel, but if you install your distro's sources (with their .config), it's
fairly risk free. just back up your old kernel. [OT: if you run lilo, don't
forget to run lilo after copying over the new kernel. TONS of people don't
realize this their first time]

Re-,
My turn to take a dive...
What about the Tascam US-/usx2y series?
Is full-duplex unavailable, when the 24bit / 48kHz scheme is set?
Should I wait some more USB 2.0 / FireWire devices to be ALSA-compliant before
buying a laptop?

first of all, sorry if this topic has been talked about to death.
At the moment i'm starting to get more and more into recording (both multi-track and synths, etc). I added on a second monitor and am now in the process of trying out different window managers (again). I'm using xfce at the moment, but i might try fluxbox again for a while.
Now for the question: which window manager are you using for audio work and why? I don't mean for this to start a flame war... notice it wasn't titled "what's the best window manager?" ;) I just want to take an informal survey of what everyone is using and see why people use what they do.
Thanks in advance,

About SoundFonts:
(reply to robert's soundfonts rants)
i havent used soundfonts at all (never), i was
planning to use them as a last resort not because
everybody has a bad attitude towards sf, but what
youve said that theyre monolithic, when im composing
i like to make new samples and load them in-the-fly to
a sampler and then process the sample more with fx and
stuff... and again... render to wave and then load- it
again... maybe change some rythmic structures and then
render again to audio and maybe the complete audio
chunk load it as a whole audio track in ardour or some
audio seq software with mixer to further process!!!
thats the way i like to make music, so the point is
that soundfount could let me achieve this easily? or
is it difficult to compile your own soundfonts... the
other problem i think ill encounter is that sequencers
cant record the audio directly from your soundcards
wavetable... (please correct if im wrong)...
on the other hand ive been searching for sf and ive
realized that maybe they will be very useful to me
because you can load pre-made drum kits like a TR-909
for example and use them easily just as if you had the
real midi module...
another question: my soundcard has 4 synths built in
right? does this means i can load 4 soundfont banks at
the same time???
on the other hand ive realized specimen is a great
sampler: everything i need (preview .wav, map
different regions, loop point editor, filter, though
more different filters would be very very nice...) and
i didnt know you could use it directly from rosegardan
through alsa midi , that excelent, just as if
specimen was a plug in, i can trigger samples from my
midi keyboard with an inperceptible latency, now i
would like to know several more things, like how to
apply ladpsa plugins to the sampler for example if i
want to use some of the ladpsa filters... how is the
audio routed from specimen back into the midi host
mixer (it displays audio in a channel called rec... )
but it has no slots for plug ins...
anyone knows how to do this??? could this be done? or
do i have to record the audio and then process it in a
standard audio track ?
thanx
ivan.

Hi all
I am trying to build fst against the tarball of wine found on the vstserver
site, the tarball vstserver-wine.tar.bz2. The version of fst I am trying to
build is 1.6.
I get the following output:

VSTServer, and VSTI compile fine.
Suggestions are welcome.

Well, they finally figured out why the Midiman quattro wasn't working
right, I have one, and its good for stereo recording, and if I can
eventually get an omni io for it I can get phantom power and volume
control and nice stereo inputs for condensor mikes (if I had them).
Usb is only really usable with decent layency for stereo playback and
recording. The Hammerfall multiface with the pc card interface is the only
game in town, until we can get am alsa driver for firewire, in which case
you'd open up the linux laptop to a lot more hardware.
