I have recently bought the ice1712-based DSP2000 C-PORT from Hoontech and
I'm really satisfied with it. I only have a little problem: MIDI!
The card has 1 MIDI in and 2 MIDI out, and the 2 outs are working fine.
However, I can't get anything from MIDI in :-(
Anyone has that card and can confirm this problem or I have to check my
hardware? Maybe ALSA get confused? With aconnect I see 2 devices (0 and 32)
both as inputs and as outputs...
I've tried on the staudio.com forum and they suggest to test the card under
windows, but (ehm..) I don't have it...

I have jack installed and working now. So, now I'm trying to get
AlsaModularSynth compiled and running. Has anyone else accomplished this
in debian stable (woody)?
I installed libqt3-mt (along w/everything it depended upon), fftw-dev,
fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to
edit the top of make_ams to agree with the location of the qt3 libs, bin
and include directories on my system as best as I could figure ... but
I'm not sure I got it right:
it seems to compile OK when I do:
make -f make_ams
though there are a lot of warnings about comparing signed to unsigned
and other warnings that flew by. Are these benign?
Anyway. I end up with an executable ams. When I run ./ams I get this:
./ams: error while loading shared libraries: libjack.so.0: cannot open
shared object file: No such file or directory
I have that in /usr/local/lib/libjack.so.0 so creating this link appears
box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0
Is that the correct sollution?
ams: cannot connect to X server
I assume this is because X is running as me (eric) and not as root. I'll
try getting out of X and starting it as root as soon as I finish writing
this message. But, is there a way to let root connect to the X server
that's running as eric?
I was sort of ok (well, not really, but I'm giving it a try) with the
idea of running jackd and its clients as root ... but, running X as
root, too? that makes me more nervous, somehow... maybe I shouldn't be
nervous about that ... I'm not sure.
anyway. i'll give it a shot with a root X session.
I'm thinking that maybe I should patch and recompile the kernel and
recompile jack to enable capabilities so I don't have to run as root.
Do those of you running jackd as root also run your X session as root?
Thanks for listening,
PS If all of this has been covered before and my questions are annoying
you, feel free to send me to the archives. I try to follow jackit-devel,
but most of it seemed to go over my head before I actually started to
try it. So, re-reading the past couple months would probably do me some
good now that I have the real thing in front of me. -edrz
First the vitals:
The computer system is a 400 MHz K6-2 with 512 MB memory, and a Hercules
Fortissimo II (Cirrus Logic Soundfusion CS4624 processor) sound card.
The OS is Linux-2.4.20 (built up from Slackware-8.0, with kernel patches
and package upgrades). I have the following ALSA components installed:
alsa-driver-0.9.0rc7, alsa-oss-0.9.0rc1, alsa-utils-0.9.0rc7,
The kernel is mostly monolithic, with the following options (abridged to
include only those I know are relevant; if folks want the complete
listing, I can easily provide it):
ALSA is the only component that I have modularized (only because I don't
have the impression it can easily be just built-in, actually), and the
following modules are loaded:
Module Size Used by
snd-mixer-oss 11120 1 (autoclean)
snd-cs46xx 58096 1 (autoclean)
snd-pcm 50752 0 (autoclean) [snd-cs46xx]
snd-timer 9392 0 (autoclean) [snd-pcm]
snd-ac97-codec 26912 0 (autoclean) [snd-cs46xx]
snd-rawmidi 11808 0 (autoclean) [snd-cs46xx]
snd-seq-device 3824 0 (autoclean) [snd-rawmidi]
snd 27280 0 (autoclean) [snd-mixer-oss snd-cs46xx
snd-pcm snd-timer snd-ac97-codec
I've been using Linux with OSS and a Media-Vision Pro-Audio-Studio-16
soundcard for years, and have basically had very little trouble with
that combination. Upgrading to Linux-2.4.x caused the sound output to
be rather noisy, so I recently took advantage of the situation to buy a
new soundcard, and upgrade to using ALSA (which I've been wanting to do
so I can investigate certain rather exciting applications such as Ardour
and the new Rosegarden).
The applications I've been using for years with OSS, (notably Dap,
Mixviews, Aumix, and a few others) all appear to mostly be working fine,
presumably through the ALSA OSS emulation. Aumixer now shows some
lables (PhoneIn and Video) which don't correspond to any inputs I have
on my soundcard, while some others (IGain and Line1) don't appear to
have any use, given the way I'm currently using the card (signal from a
hardware mixer going to the Line input, and signal from the main, front
line output going back to the mixer).
I can play back sound files without any problem. In fact I've also tried
a few new (to me) applications, such as Audacity, ProTux, and (though
I'm having problems with it I won't cover here) Ardour, and they too
play back sounds quite nicely (the sound is "grainy", though, perhaps I
need to investigate the Low-Latency issues more, or increase the size of
some buffer somewhere).
I can send sound to the computer, and listen to that sound coming back
from the computer (adjusting the level with the "line" level in Aumix,
for example), but if I try to record that sound (in any of the
applications I've tried, including all those listed above), with "record
enable" selected in Aumix, I get no audio recorded (silent sound file).
Also, I find it interesting to note that I can record-enable only one
input source at a time (contrary to my old Media-Vision card). I'm
assuming that's a function of the hardware, though and can't be fixed in
Finally, we get to my questions:
- Can someone point me in the right direction(s) to find a solution to
this, so I can record audio (preferably from numerous sources) into
my computer? I'll be perfectly happy with pointers to documentation
(though I expect to get at least some to documentation I've already
read, because I think I've repeatedly gone through all the
documentation I already found myself), and suggestions to upgrade
- I've tried to start Jackd at system boot, with the following command
added to my rc.local file:
/local/bin/jackd -d alsa -d cs46xx -p 512 &
Jackd fails to start at that point (I'm afraid I haven't noted the
exact error message, but I can make a point of doing so next time I
reboot the system), but it does start when run manually from a root
shell. Does anyone have any idea why jackd might not start at boot
time, (perhaps the ALSA modules aren't loaded yet at that time)? If
I understand my boot sequence properly, kernel modules are setup
(via "depmod -a") before rc.local is run, so the modules may not be
loaded, but they should by that point be loadable (they load
automatically by the kernel in regular use).
- Is it possible to build ALSA into the kernel?
- on a slightly unrelated point, my new soundcard has a built-in
synthesizer with at least some features I'd like to explore. Though
I know this won't replace any of my hardware synths (or some of the
software synths I've begun to play with), I'd like to play around
with some of its built-in sounds, and probably use it (at least
until I get something better) as my "preset playback" device,
controlled from an external MIDI controller. Does anyone have
suggestions for how I might go about that? (again, simple pointers
to existing documentation would be more than appreciated).
In case people are wondering about my specific intended application,
I'd like to use a Roland Octapad to trigger percussion sounds from
the soundcard's built-in synth.
Thanks in advance for any pointers people can provide....

New Release : horgand 1.0
News in v1.0 (19/06/2003)
-Added small auto-accompaniment, Looped Drums and a Bass line in
a wave table way.
-added chord recognition
-some free drum loops and bass samples.
-bugs solved in DSP effects, now more stereo, minus noises :-)
First i want to say something, personally i dont like any kind of
organs, because many people use it for work, and this is not good for the
musiciens. In fact i wonder the day when the musiciens dont want to record
anything, anymore. Only write the papers, and play live, that's music.
Please read the Readme file for how to add new loops and other questions.

I'm considering building a Linux DAW and have a few questions. First
of all I have a Delta 1010LT soundcard. Does anyone have experience
with using that card on Linux? Any caveats I should know about?
Secondly, I think I've narrowed down my mobo/CPU combination and
wonder if there's anything to watch out for there. Here it is:
CPU: AMD Athlon XP 2400 Thoroughbred 2.0 Ghz 266Mhz FSB
Mobo: Asus A7N8X Deluxe NVIDIA nForce2 SPP, nForce2 MCP-T chipsets
Also, related to hardware, there seems to be a myriad of hard disk
choices out there. The mobo seems to have built in support for
standard ATA IDE and SATA. I haven't read the manual yet to find out
the details, but I'm thinking about going the older ATA100, 7200RPM
route since the drives are about half the price. Am I shooting
myself in the foot by doing this? Should I buy a PCI IDE controller
or is it possible to get reasonable results from the onboard
controller? What are some drives you have had success (or failure)
Finally, I would like to be able to record in remote locations
without having to bring along a monitor, keyboard, mouse, etc. I was
thinking about using my laptop to open a remote X session on the main
box. Is that a practical scenario or would that drain too many
resources on the main box to be productive?
This is mainly an experimental project. I don't need this box for
everyday professional use or anything. I'm just trying to build a
Linux box on a shoestring and hopefully get it to work with the audio
stuff. I'm really trying to keep costs down to around $400 US --
pipe dream maybe, but we'll see.

Dual head works great with my system using an ATI 8500 card. I am

latency kernel. The ATI drivers run well on my system and drive both

I am using the 2.5.73 kernel, and ALSA works great
built in, using the proper config options. Now I
have a need for jackd support, and so I'm guessing
that I will have to go back to the tarball distro
in order to give the --with-jack option to the configure
With the 2.4.x kernels, the instructions were to
select "sound card support" (soundcore) and nothing
else. Would that be the same as checking ALSA support
in the kernel with no other options?
Hello, Everyone :)
Does anyone know of a good volume leveler that I can use on Red Hat 9?
To clarify what I mean (if you didn't figure it out already), I want
something I can run wav or mp3 files through and make them about the
same volume, so that when I make CD's from varied sources, I don't have
any jarring, unpleasant transitions between songs. I would prefer a
command line utility, but I will be willing to try a graphical program
if necessary :)
I already searched for this item on Google, and on freshmeat as well :)
Thanks in advance for your help :)

Has anyone successfully used a pci-pcmcia converter to let them use cardbus
sound via pci? I've got a vxpocket, and I certainly can't afford to shell out
$2-300 for another soundcard. Would using a converter be a suitable solution?
