Clemens,
Thanks for the response. One comment I forgot to make in the first
post. This MIDI interface works fine under Windows, so whatever causes
the problem is purely a Alsa MIDI issue. If we can figure it out, then
we can fix it.
I agree that it sounds like this sort of one note per timer tick.
When the interface is supposed to send a chord, it sends what sounds
like an arpegiated chord. It's all smeared out.
Is there some example code I could look at to understand implementing
a FIFO? However, if there is a FIFO Full indication, doesn't we need to
know _how_ it's indicated? I would assume it's different for all cards?
(Bus possibly similar for cards from the same manufacturer?
Also, this is the HDSP 9652, which is a single PCI card. Is this
problem showing up for the DigiFace/MultiFace type cards?
Thanks,
Mark
[excuse cross-posts... im just desperately trying to get some info on
this...!]
have establised so far its not the mouse, i dont think.... and its not
oss-emulation because alsa-player has the same problem.
there is sound coming out, but very heavily distorted...
also it seems only to be coming out of the right channel, the left
channel just has faint distortion....
never ever come across this one before!!!!!!
any help would be very much appreciated...
thanx

hi,
i'm just checking the archives re: patrick's problem with audio quality
under X, as my quattro is configured ok now but making only loud
feedback noise when i go to play anything....
my mouse section in XF86Config-4 is as follows:
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "PS/2"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons"
Option "Emulate3Timeout" "50"
EndSection
i'm using the trackpoint on my thinkpad 600E - should i change any of this?
i think i'm using gdm as well - at least, i have a file called
/etc/gdm-root.conf - no /etc/gdm.conf tho....
please help.... i'm really stumped for what might be causing all the
feedback noise as its never happened before in mdk 8.2.... everything
was fine there....
im using supplied alsa rpms from mandrake 9.0 (there was a long
discussion on the pros and cons of this before, have gone with the rpms,
against my preference but because its hard to extract them once
installed)....
thanx

Be gone foul bugs!
* fixed control output ports segfault
* fixed desktop installation prefix stuff
* fixed bug dealing with duplicate plugin ids
* now quits when you close the window
* added a "New" option to clear the rack
* rack is now automatically cleared when you load a file

Hi,
I'm looking for a platform for signal processing, who can be used in
command line mode ( matlab like ), but is based in low level code ( c or
c++ ), and block based signal chain. I wish i could find some kind of
front end to any standard plugin types.
It was desirable also that the standard plugin used is able to handle
data other than audio ( not so hard, i believe ), and in other domains
than time ( e.g. frequency, statistical, and weirdo like domains ).
Preferably it should have support for gui also, basically for plotting
graphics only.
thanks all,
Fabio
With help from a few kind people here, I got my ALSA sound working
with xine. However, this was at 8 bits of color depth, and the
video picture was not too good. So I tried 16 bits, which made xine
fail, as it did MPlayer. But at 24 bits, MPlayer came to life and
showed a picture that was (probably) as good as it gets.
But... MPlayer doesn't like ALSA sound. It tries to keep video and
audio in sync for 10 or 15 seconds; then it gives up and goes silent.
It says my system is too slow; one of the reasons might be slow
audio.
So I thought I'd try the via82cxxx_audio module that is in the
"official" 2.4.20 kernel.
But... I can't insmod the module. It complains
/lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: insmod /lib/modules/
2.4.20/kernel/drivers/sound/via82cxxx_audio.o failed
/lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: insmod via82cxxx_audio failed
(No, neither syslog nor dmesf offers more information.)
Am I missing a /dev? Which one?
Thank you,

Hi,
I just bought the obove card (an ES1969 Solo-1 apparently), in order to do
MIDI, but I cant seem to get anything to work.
$ cat /proc/asound/Solo1/midi0
MPU-401 (UART)
Output 0
Tx bytes : 1400
Input 0
Rx bytes : 0
Buffer size : 4096
Avail : 0
Overruns : 0
But I tried connecting the external midi device to ASM with kaconnect and
nothing appearing in the log window and the number dont change in proc
when I press keys on a keyboard.
I've replaced the joystick->midi cable and I'm not sure what else to try.
Help!

just a quick question (hopefully). In ardour I've been able to get a track to
playback while recording another track, but I can't seem to play more than
two tracks at a time, nor am I able to play two tracks while recording
another. Is this a ALSA/soundcard limitation (I have the intel 8x0 series)?
Okay, I lied, one more quick question... I've had ardour not play back samples
when recording and I can't seem to put my finger one what causes it to mute
the sample playback and what allows it to do duplex.
Thanks all
Jonathan
Just to let everyone know, I have created a new mailing list for the
OMRL at my studioconsul.net domain.
To subscribe, send a blank email to: omrl-subscribe(a)studioconsul.net
To unsubscribe, send a blank message to:
omrl-unsubscribe(a)studioconsul.net
To send messages to the list, send messages to: omrl(a)studioconsul.net
You will need to confirm your subscription or unsubscription to/from
the list. I also still need to figure out how the archiving system for
this list software works.
This is just a quick and dirty mailing list for now, so once I get a
server and the OMRL domain up and running, I will probably migrate it
over there. That should not be too difficult, though.
See you on the new list. :)

Hi,
I asked about this two weeks ago but got no responses. I'm hoping
this time I hear something back from other owners of the same hardware.
I recently purchased an RME HDSP 9652 card. The card is working fine
for audio, but the MIDI interface is a timing disaster. The interface
works, but won't keep time. A 2 minute song is Rosegarden takes abut
2:45 to play every time. You can hear how the HDSP isn't delivering
closely spaced MIDI events together, but is sort of smearing them out.
My machine is set up using the PlanetCCRMA system. According to
Synaptic my Alsa driver is from CVS:20021216. Jack is 0.44. This machine
works just fine with the MidiMan 2x2 interface. No timing problems at
all.
Has anyone else purchased this card? Used the MIDI interface on this
card? Gotten better results with this card?
Can anyone suggest how I could go about fixing this myself? I'm not a
programmer, so really hacking the code is doubtful, but this driver is
acting like there is just a basic mistake somewhere. Possibly I could
find it if I knew where to look.
I hope someone will respond to this email so we can get something
going to get this fixed. I really need this interface to operate soon.
Thanks in advance,
Mark
