Is anyone familiar with how smp_affinity works? I have a dual
processor (xeon p4 single core, hyperthreading off) machine and while
experimenting/tweaking I discovered IRQ's with smp_affinity values
besides 1 or 2. Is this typical behavior?
Thanks,
Ben
Hi everyone!
I just compiled a sound generator, which can be controlled vai MIDI, it uses
simpe raw-midi and jack as output, via bio2jack.
Now I have horrible latency 0.2-0.5sec (rough estimate). Where should I
start looking in my setupt. I know others had the software running without
problems.
Sorry for being so abstract, but I'm not allowed to mention the software.
:-( But I could post parts of the source if necessary.
My setup is:
Debian Lenny with custom built kernel 2.6.24-rt1
JACK subversion 0.109.0
jack-commandline:
jackd --timeout 4500 -R -d alsa -d hw:1 -r 48000 -p 128 -H -M -z shaped
ALSA version 1.0.15
Any idea where to optimise?
Kindest regards
Julien

hi,
does anybody already use this interface and can recommend it? I'm
looking for a "non-USB" interface and would prefer a cardbus device.
Basically I love my currently used Lexicon Omega USB card, but when
dealing with some synths the USB-bus seems to come to it's limits...
I use kernel 2.6.25.4-rt4 in opensuse 10.3 on a Thinkpad R61 with T8100/2GB
thanks and best regards

I was using coaxial output in my SB audigy 2 planinum for both DIGITAL
and ANALOG audio output. But after a while (I do not know the real
reason, maybe a kernel upgrade or my LIRC configuration attempt) I
couldn't get any analog audio from coaxial, i was getting only digital
output. Analog output was only coming from analog output. I undid my
configurations etc. But I did not succeed. I googled a lot and there
was no solution for my problem. I want all my audio output from
coaxial, so there would be no need switching to analog to digital back
and forth in my sound system. If anybody can lead me to a solution or
help me, I would be appreciated.
Thanks in advance.
Saw this come across the CDM feed today, and was hoping someone could help
me track down a similar app that'd work under Linux; I'm interested in
sequencing a collection of sounds in a semi-random rhythmic fashion -
Anything ya'll know if that'd fit the bill?
I'm also interested in software at all along the lines pseudo-random /
glitchy / fractal / math inspired music.
Thanks!

This could be worth a read:

It's something I'm interested in doing myself, but haven't had the time to try it yet - I'd be interested in your thoughts on GIMP & MIDI.

That's very impressive Niklas - as if they took all the instruments out
of a symphony orchestra and replaced them with power tools!
Thanks - I downloaded the whole album.

Does anyone know of a piece of software for Linux that will analyse a
voice singing and generate the equivalent MIDI. This does not have to
be real time, though that would be a bonus.

Hi
I'm trying to compile zynaddsubfx from svn on ubuntu 7.10, and suspect
my libjack's too old:
atte@ajstrup:~/music/synth/zynaddsubfx$ jackd --version
jackd version 0.103.0 tmpdir /dev/shm protocol 16
First I enabled this in Makefile.inc:
LINUX_AUDIOOUT=OSS_AND_JACK
atte@ajstrup:~/software/zynaddsubfx/08_06_09/src$ make
<snip>
JACKaudiooutput.C: In function ‘void JACKhandlemidi(long unsigned int)’:
JACKaudiooutput.C:120: error: ‘jack_midi_port_get_info’ was not declared
in this scope
make[2]: *** [JACKaudiooutput.o] Error 1
make[2]: Leaving directory
`/home/atte/software/zynaddsubfx/08_06_09/src/Output'
make[1]: *** [Output] Error 2
make[1]: Leaving directory `/home/atte/software/zynaddsubfx/08_06_09/src'
make: *** [all] Error 2
Then I applied zyn-jack-midi-branch-adjust.patch:
atte@ajstrup:~/software/zynaddsubfx/08_06_09/src$ make
<snip>
g++ -O6 -Wall -DOS_LINUX -DALSAMIDIIN -DFFTW_VERSION_3 -DASM_F2I_YES
-ggdb `fltk-config --cflags` -DJACKAUDIOOUT `pkg-config --cflags jack`
-c -o JACKaudiooutput.o JACKaudiooutput.C
/usr/include/jack/midiport.h: In function ‘void JACKhandlemidi(long
unsigned int)’:
/usr/include/jack/midiport.h:72: error: too few arguments to function
‘int jack_midi_event_get(jack_midi_event_t*, void*, jack_nframes_t,
jack_nframes_t)’
JACKaudiooutput.C:122: error: at this point in file
make[2]: *** [JACKaudiooutput.o] Error 1
make[2]: Leaving directory
`/home/atte/software/zynaddsubfx/08_06_09/src/Output'
make[1]: *** [Output] Error 2
make[1]: Leaving directory `/home/atte/software/zynaddsubfx/08_06_09/src'
make: *** [all] Error 2
Any idea? I asked this once before (but forgot the answer + about a year
has gone by): What's the best way to install zyn with all the latest
stuff (mutex hotfix and extended mono)? Are they all in svn?
