USB NEWS FLASH!
The latest hotplug upgrade from SID now installs uhci-hcd without its being
requested in /etc/modules. This module still does not unload correctly,
however, so I guess I need to blacklist it so I can shutdown normally ...
ugh--blacklisting this does not work (the original usb-uhci had been
blacklisted as well and always loaded--at least ext3 is working!).
The new hotplug loads a lot of stuff, in fact:

(Those -5 errors apparently are not preventing the MIDI usb devices from
operating. Can cat /dev/midi1 and see my key-presses.)
However, the MIDI devices is the only one I have connected to one of the two
(older system) USB ports. Should not hotplug load any of these other should I
plug one of them in? I have no X-box, no dongles, no nothing.

Thank for the many ansawers I've received. Anyway, that still doesn't work.
I've typed jackd -S -d alsa -r 44100 & but the prompt don't come back
there's always a problem (xrun ...don't know what it's meaning) and when
I try the jack metronome , jack_metro --bpm 120 &, the answer is :
[moebius@localhost moebius]$ jack_metro --bpm 120 &
[1] 2307
cannot connect to jack server
[moebius@localhost moebius]$ cannot connect to default JACK server
jack server not running?
[1]+ Exit 1 jack_metro --bpm 120
[moebius@localhost moebius]$ jack_connect metro:120_bpm alsa_pcm:playback_1
cannot connect to jack server
cannot connect to default JACK server
jack server not running?
Well, if someone has another(s) idea(s) ....
cordialement,
Well, I'm always trying to get midi audio recording working, or at least
just one of these :) ; well, I'm trying very hard but .... nothing's
working ; I'm trying since a long time but .....
I have a P4 computer and mandrake 9.2 with a low latency kernel (
2.4.22-21mm.2mdk).
Well alsa is running and when I launch alsaconf, it says that my sound
card is "intel 8x0 Silicon Integrated Systems [SiS] Sound Controller"
(in fact, sound is integrated in the motherboard (an Asus P4S8X-X), and
the motherboard doc says that the chip is an ADI AD 1980 6-channel audio
codec) ; in an another place, I've also seen SiS 7012...... Alsaconf
don't perform the last thing, playing a song 'cause something is missing :
Loading driver...
/usr/sbin/alsaconf: line 568: rcalsasound: command not found
Setting default volumes...
===============================================================================
Now ALSA is ready to use.
For adjustment of volumes, please use alsamixer or gamix.
Have a lot of fun!
So I'm trying to launch jack and, as root, I type #jackd -d alsa -r
44100 and here is what I get :

Well if someone have any idea, it would be nice to get this working ; I
really need to make music with linux, I don't want to be obliged to run
my atari falcon with cubase audio until the end of time !!! But, really,
I don't know what to do....
cordialement,
Hello,
I have a couple of related questions I am hoping some kind soul on this
list might clarify. I'm currently running Fedora Core 1 with
the CCRMA kernel 2.4.24 + CCRMA alsa RPMs.
I'd like to write a small test program to send/receive to a midi
device connected to: 1) midi port on sound card, 2) midi port on
USB MidiSport 2x2. The output of aconnect -lio shows
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 64: 'Rawmidi 0 - ES1371' [type=kernel]
0 'ES1371 '
client 72: 'Rawmidi 1 - MidiSport 2x2' [type=kernel]
0 'MidiSport 2x2 Port 0'
1 'MidiSport 2x2 Port 1'
When looking in the /dev directory, I see different flavors of midi
devices (eg /dev/amidi0, /dev/dmmidi0, /dev/midi0, /dev/rmidi0,
/dev/snd/midiC0D0, etc.) My test program needs to open a connection
to the appropriate devices. So, my questions are, what device does
alsa map to the sound card midi port and what device would I use
for the USB connected MidiSport?
Thanks in advance for your help.

Was wondering if it is possible to write a relatively simple startup
script to start Jackd, AlsaModular synth with my specific file/patch
(AMS will start Jack on its own too) then patch capture 1 & 2 to AMS
then AMS to PCM's out, and then "wire" my midisport 2x2 port "A" to AMS
midi in?
It would be nice to boot at the gig, click on an icon and have
everything come up. Also, I run everything 'su root' in a console too.
thanks
P.S. Running Mandrake 9.2

Your milage will vary ;) It depends on the positions of the monitors,
how loud they are, how loud the sound sources are, and how picky the
musicians are. It's just that it's much harder to get away with delay in the
monitors than it is in the mains. If you can make it work, more power to
you!
I wish you well in your endeavor!

The latest version of the realtime Linux Security Module is now
available in the usual directory, <http://www.joq.us/realtime>.
This version handles the new concurrent groups mechanism Linus
introduced in 2.6.4. It still works with earlier 2.6 kernels. There
are no functional changes. Unless you are running 2.6.4, there is no
reason to upgrade.
The realtime LSM is an installable kernel module that enables realtime
capabilities for any 2.6.x kernel without needing to directly patch
the kernel. It was written by Torben Hohn and Jack O'Quin, who make
no warranty concerning the safety, security or even stability of your
system when using it. It is provided under the provisions of the GPL.
Thanks to Martin Habets for pointing out this kernel change and then
showing me how to handle it.

Hello,
I see that you have security capabilities built in. Do you need to enable it
somehow to get jackstart or other applications which require caps to work?
I can't get 'jackstart -R' running without Joq's realtime module I was
talking about..

hmm.. excellent. I am thinking of mixing onstage monitors and PA while
recording. At what latency do you think the delay would become noticeable?

I have the exact same problem and the exact same questions. I haven't seen any responses to Greg's email, so I thought I would reiterate the question. Anyone have any insight?
