[after writing this I found
http://lists.agnula.org/pipermail/users/2005-June/006358.html in the
agnula-users archive. many of the same points are raised, but it appears
not yet corrected in the wiki.]
[and now I've found and have begun reading the more recent thread:
http://lists.agnula.org/pipermail/users/2005-June/006417.html
still I'm wondering which of the deb lines below is correct]
There seems to be some inconsistency on the agnula pages on the correct
apt sources line. I want to try adding demudi to a fresh debian sarge
install.
Here: http://demudi.agnula.org/wiki/InstallApt
it says use this:
deb http://demudi.agnula.org/packages/demudi testing main
and in the FAQ:
http://demudi.agnula.org/wiki/DocumentsFaq#Upgradingexistinginstallations
it says use this:
deb http://apt.agnula.org/demudi testing main local extra
Are those 2 apt sources the same? if not which is correct?
These instructions from the FAQ are somewhat confusing:
"* from the command line issue:
# apt-get install demudi
* install the tasks you are interested in. To have a look at them run:
# apt-cache search demudi
The task demudi installs them all."
It should probably tell the user to apt-get update after editing
sources.list. Also, the two statements above appear to be contradictory,
or at least out of order.
Installing package demudi appears to only install some pixmaps and pngs.
Attempting to install any of the demudi-<foo-task> packages returns
saying that it's not available and is replaced by demudi. Maybe these
only work if you use taskselect?
I must be missing something pretty basic here.

New subject: [linux-audio-user] Hardware recommendations
Hey all,
I'm relatively new to computer audio recording, and have been using
Linux for about a year and a half, and I need some recommendations as
to what hardware I should get.
I'm trying to set up a recording studio capable of at least recording
drums (4 or 5 channels?), guitars (2 channels), bass (1 channel), and
vocals (1 to 4 channels). I also need a MIDI controller. I'm looking
at the RME Hammerfall line of products because of what I've heard
about their compatibility with Linux.
The equipment I already have is:
1. A couple SM57s, as well as a set of drum mics
2. An EZ-BUS (8 track mixer with optical ADAT i/o, 2 channels XLR w.
phantom power), unless my friend in Mexico sold it (this will also
determine whether or not he's my friend).
3. A computer.
My questions:
1. From what I understand, the wordclock available in the 9652 models
is to syncronize all the audio, and that sounds like something I need.
Is this true?
2. The DIGI line doesn't have MIDI, and the HDSP line does. How hard
would it be to use an emu10k1 midi in and syncronize it with the rest
of the audio? Is it worth the trouble?
3. I was looking at a Berhinger ADA8000, because it would provide 8
channels with phantom power, and ADAT I/O. Does this look like a good
idea? Any other suggestions?
So that's where I'm at. I don't want to spend TOO much money, but I
also want something as functional and versatile as possible.
Thoughts?
Thanks,
Nathan

yes, all of your digital audio devices should be clocked from one source.

line does. How hard
would it be to use an emu10k1 midi in and syncronize it with the rest
of the audio? Is it worth the trouble?
don't know about that, but i use an HDSP multiface, and it is delightful
-- rock-solid for both midi and audio. i use it as my wordclock master
as well.
3. I was looking at a Berhinger ADA8000, because it
would provide 8
channels with phantom power, and ADAT I/O. Does this look like a good
idea? Any other suggestions?
i use an RME octamic and a focusrite octopre (both with the digital
option cards). they're both great. the focusrite has a basic but useful
dynamics section on every channel, and is perhaps slightly more "open"
sounding. the octamic, on the other hand, has a cool resettable peak
hold feature and can be operated on batteries. the multiface can also be
operated on batteries, so if off-the-grid portability is at all useful,
a laptop with multiface and octamic gets you eight channels without ac
power.

I just picked up an edirol UA-1000 in the hope that it would "just
work" w/Linux. The feature set looked perfect for what I wanted to do
- 4 mic preamps, 1 high-z interface, 4 balanced line inputs, midi...
It's not recognised properly by linux (at least, at present), and
panics the system on removal.
I'm going to play with it for a few days but it's already got one flaw
that makes me want to send it back - when my laptop's plugged into
power it feeds hum through the whole system via the usb connector.
So I'm looking over the various bits of RME gear in the hope I can
assemble something that WILL work under linux 'cause I'm sick of doing
stuff in windows. It looks like the RME cardbus card (299$ US) + the
multiface (~700$ US) will work best. I wish it came with mic preamps
but I guess you can't have everything.
Is there any hum issues with the RME stuff, or any alternative
box/card/firewire/usb-2.0 thing that works well under linux that
combines both balanced 1/4 I/O with mic pres?

That was a kernel bug, you need to update your kernel to 2.6.12 or get a
newer ALSA.

Sounds like your laptop is poorly shielded. I'm not sure this is the

Ha! I wonder how good edirol has been about releasing detailed

As it was, after upgrading to the 2.6.12+alsa+patch git kernel I

Hmm, that's not good. A machine check exception normally indicates a
hardware problem. Are you overclocking the machine?

No. Box (an emachines m6805) seems otherwise reliable (uptime in
multiples of days)
I think that's just a warning message saying that it will log machine
check events, not an actual machine check...
I will attempt a build from the clean 2.6.12 sources later on... but I
wanted to ask if I was maybe missing something in the usb-audio init
or in /etc/hotplug that would be notifying the kernel of what exactly
was plugged in - I don't know anything about the usb hotplug
system....

A friend of mine with a Mac Powerbook had (has) the same problem.
I forget what his USB to MIDI converter is, but it is outboard.

got one flaw that makes me want to send it back - when my

same for me on a Dell i8200. I do not guess that this has
anything to do with the device itself but with the shielding
of the notebook. There are many circuits in a very small
chassis, so this can happen.
I have put in two rechargeable batteries which grants me 5h of
audio work without hum when disconnecting the power supply.

I also have a Dell 8200, what I've done is remove the grounding and the
noise is gone. (yes, I know you shouldn't do that...)

yes, it's dangerous. Very dangerous.
A further thing one could try is to put an optical coupler
between the notebook/soundcard and the rest of the audio
equipment. Any experiences?
