Hello All,
I have a few general questions for those people using DeMuDi,
- Which version are you using - woody or sid?
- Is anyone using a sid DeMuDi over a sarge (or even woody) base Debian?
- How much software are you replacing with upstream source balls or CVS
versions?
- How 'usable' is your setup - I doubt that many have a workhorse
solution, although there seem to be a few success stories on this list
and elsewhere, but is it still really just experimental (in the Debian
sense of the word)?
Thanks
Darren

Darren,
I have a few general questions for those people using
DeMuDi,
- Which version are you using - woody or sid?
Sarge. as i mentioned in a previous email, the "official release" of
this will be in a few weeks. i was lucky enough to do a workshop with
one of the developers a week ago, so i really got a lot of the bugs out!
- Is anyone using a sid DeMuDi over a sarge (or even
woody) base Debian?
is there a Sid Demudi?
anyway, for the record, here's what i did to get it running:
i installed Woody with the ext3 file system, then updated to Sarge,
built my own custom kernel with the low latency and preemptive patches
[don't forget the devfs and reiserfs support!], compiled my Alsa and
Jack, and got the Demudi apps. so, technically, i am only half-using
Demudi. i skipped using the kernel, although i have gotten the newest
kernel version running nicely on my laptop, there were still some issues
with it keeping its Alsa settings and such. also, some hand-tweaking is
required of the /etc/fstab to add the /dev/shm file system for the Jack.
next step is to ditch the ext3 file system and replace it with reiserfs
for smoother low latency operation, but that is beyond anything that
Demudi would do right now...
- How much software are you replacing with upstream source balls or CVS
versions?
i still get Alsa and Jack from source. especially Jack, as i want to
seriously optimize it right now, so i am trying as many tweaks as i can
find in the compile. i am not sure if the Demudi Jack version is
optimized for realtime operation by users [instead of root, which
crashes the shm file system anyway under Demudi], and if it is, then it
may not be possible to use it with an ext3 file system on a 2.4.20
kernel without lockup. if Guenter or somebody else has patched the
2.4.20 Demudi kernel package against this, it is not a problem. but i
don't know if all this is worked out yet.
other than that, there are almost zero sound apps which i have gotten
from upstream. many of the Demudi Sound Apps packages in the Sarge are
compiled from CVS versions [espc. PD, Ardour, etc...], although probably
not the LATEST in many cases, although the PD and related externals
versions I can vouch for specifically as being only a week old!
- How 'usable' is your setup - I doubt that
many have a workhorse
solution, although there seem to be a few success stories on this list
and elsewhere, but is it still really just experimental (in the Debian
sense of the word)?
with Jack fine-tuned, i see my setup being highly usable... plugging PD
and Ardour together alongside my HDSP card is my main goal, and i think
i am almost there. right now, it is just as experimental as i am.....
best,
Derek

Thanks for the info Derek - this is very useful.
Where do you get sarge DeMuDi? Both agnula.org and demudi.org mention
woody & sid, but nothing in between.
Basically, I'm trying to get a musician friend off an old Atari
ST/Notator setup (which is preferable to Windows). Although problems are
to be expected at the moment, it needs to be somewhat usable. I'm hoping
this can work, because as a developer and an ex sound engineer it's an
area I can really get my teeth into :)

Darren,
the Sarge version of Demudi is unofficial [actually, the source below is
Guenter Geiger's own development version], so use with caution. try it
by adding this to your apt-get sources:
deb http://devel.demudi.org/demudi sarge demudi
then 'apt-get update'
if you want to use the Demudi kernel, you will still have to do a few
things:
1) first, after upgrading to Sarge, 'apt-get install demudi-base'. once
the Alsa, Jack and kernel packages have been installed, add the line
initrd=/initrd.img
to your lilo.conf BEFORE rebooting [don't forget the 'lilo' prompt
after this...]
2) mkdir /dev/shm
3) add the following line to /etc/fstab:
none /dev/shm shm defaults 0 0
[this is a virtual file system which Jack uses. you will run Jack as
user, not as root. if you run it as root, it will make a logfile in
/dev/shm that will jam up everything, and you will have to remove this
file to continue.]
4) reboot. if all goes well, you will boot into Demudi kernel, and then
you can 'apt-get install demudi-soundapps'.
5) Demudi uses info from an app called Discover to configure your Alsa
settings for your soundcard. this wasn't too reliable last I checked, so
if Alsa doesn't keep your soundcard info after each reboot, I recommend
you configure it manually, with info from the Alsa soundcard matrix on
the Alsa site, in the following places:
/etc/asoundrc
/etc/modutils/aliases
look here for more tips on this if you don't know how to do this:
http://myweb.cableone.net/eviltwin69/ALSA_JACK_ARDOUR.html
good luck,
Derek

hmm, funny, I don't have this problem. I'm not 'running' demudi, only a
few items including the kernel (2.4.18-586-demudi installed _long_ time ago) but things
like alsa + jack and many others I compile myself. I run jack as root (it doesn't
allow me run with -R) and /dev/shm in fact gets filled with some stuff but it cleans up
afterwards... Maybe I didn't run it long enough? What am I doing wrong? :)
jack version 0.67.2.

Michal,
as Guenter Geiger pointed out on the PD list a little while ago, Jack
has gone through a lot of changes in the past few months. one of them is
this shm thing. the no-running-as-root thing is Demudi specific. so, as
the old sayin' says, if it ain't broke, don't fix it! i guess this
shouldn't be much of problem if you compile all your jack-aware apps
yourself, and haven't gone for any really new versions. but maybe the
latest CVS versions of PD would need this new Jack. dunno know for sure,
as i am not a devloper :-)

trouble using jack / MIDI editors - more to do with fact I'm running it on a
P133 (well somebody had to!). Have not had time to recompile kernel & mess
about with cvs yet. (Too much actual playing music to be done - Guess I'm not
enough of a geek :-). Otherwise fairly useable.
DeMuDi is still in beta, but an updated distribution has been promised for
sometime soon.
