hi all,
i'm not really familiar with the ladspa development process, but is
there any quality assurance for ladspa plugins?
i have been implementing some of my filters as ladspa plugins, but when
trying to compare them with others, i found, that some of the plugins
did not do, what i expected them to do (a white noise generator did not
generate white noise, a shelf filter was highly unstable when changing
parameters) ...
of course, all plugins are free (as in speech), without any warranty,
but i still think, that there should be a certain amount of quality
assurance, if we want people to use the ladspa plugins ...
have there been some thoughts of introducing some kind of ladspa qa?
best, tim

hi
in an alsa-seq enabled application i would like to automatically connect
to all available "hardware" midi devices on startup.
however i have found no way to find out, which clients are real midi
devices and which are not.
my first attempt just connects to everything except itself and client-0
("system"), which is rather sub-optimal, as it includes the "midi
through" which tends to lead to wild midi feedbacks (our application
_can_ do midi through too...)
unfortunately i haven't found any documentation.
what i have found is:
- http://www.alsa-project.org/alsa-doc/alsa-lib/group___sequencer.html
(saying that "user clients" have ids 128..191; this is fine, to filter
out other applications, but not enough for me)
- http://alsa.opensrc.org/index.php/Aconnect (which gives a "simplistic
guideline for client numbers": 0..63=internal; 64..127==devicedrivers;
128..?==userapps; this would be perfect, but unfortunately this just
seems to be outdated information; e.g. i have 4 hw-midi devices
connected and they are assigned the numbers 16,20,24,28)
any hints?
or iam i totally out of my mind for trying to (optionally) a(uto)connect
on the application-side?

Hi,
Does anyone know the status of Timidity's development aside from the one
posted on its sourceforge website (timidity.sourceforge.net)?
The Japan URL, timidity.jp seems to be down as well for the longest time I
could think of.
In any case, it's still great software and I use it a lot (and will most
definitely continue to use it for some time).
Is the project (almost) dead? Where could we see traces of its life?
Thank you very much.
Best Regards,
Carlo

Greetings,
I'm trying to compile Wine 0.9.44 as a 32-bit executable on an AMD
64-bit system (that is, with -m32, not in a chroot). I've done this
successfully in the past under 64Studio, but my recent crash & reinstall
has introduced something (or left out something) that leaves me unable
to build Wine. Here's the problem point :
gcc -c -I. -I. -I../../include -I../../include -D__WINESRC__
-D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing
-Wdeclaration-after-statement -Wwrite-strings -Wpointer-arith -g -O2
-D__i386__ -o interlocked.o interlocked.c
{standard input}: Assembler messages:
{standard input}:38: Error: suffix or operands invalid for `push'
{standard input}:39: Error: suffix or operands invalid for `push'
{standard input}:46: Error: suffix or operands invalid for `pop'
{standard input}:47: Error: suffix or operands invalid for `pop'
make[2]: *** [interlocked.o] Error 1

make[1]: *** [port] Error 2
make[1]: Leaving directory `/home/dlphilp/src/wine-0.9.44/libs'
make: *** [libs] Error 2
Here's the code in question :
__ASM_GLOBAL_FUNC(interlocked_cmpxchg64,
"push %ebx\n\t"
"push %esi\n\t"
"movl 12(%esp),%esi\n\t"
"movl 16(%esp),%ebx\n\t"
"movl 20(%esp),%ecx\n\t"
"movl 24(%esp),%eax\n\t"
"movl 28(%esp),%edx\n\t"
"lock; cmpxchg8b (%esi)\n\t"
"pop %esi\n\t"
"pop %ebx\n\t"
"ret");
And here's my GCC :
dlphilp@64studio:~/src/wine-0.9.44$ gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
Maybe I need to use a different gcc version ? Whatever, there's nothing
on Google that clearly points to a solution, so I turn to the GLAD team
(Giants of Linux Audio Development) for guidance. Any suggestions or
advice that might move me towards resolving this difficulty ?
Best,

Thanks, Cedric, but I still got no joy. :(
In fact, I received exactly the same error message, i.e. referring to
push, not pushl as I'd expect. Any idea why that happened ?

Hello,
my friends and I are developing a Computer Game and it should run on
Linux, Mac and Win. Now we're thinking about Audio Effects. Generell
reverb, compressor with sidechain (to compress the signal when speech is
active, so its clearly heard, no matters how the player has set his
audio balance. you know... like in Radio Stations).
We are using FMod4 and searching for a platform indipendent effect
system. Maybe there is LADSPA port to windows? Or have you other
suggestions?
greetings,
Nils

still IMHO, i think this is quite a good idea, the two service must refer to
the same data. It's a little bit in the way of ""libfreesound""
Hello everybody,
Finally, after what does seem like ages (mainly because there literally
has been ages) since the last release, here is finally what we have
decided to call MusE 0.9!
MusE is a multitrack midi/audio sequencer with support for internal and
external softsynths, in the same vein as popular commercial music
applications like Cubase, Logic, etc.
MusE has been in transition towards a redesign dubbed MusE 1.0 and there
wasn't supposed to be any more development in the old (0.7,0.8, now 0.9)
branch.
But, due to fresh developer interest and lots of angry users, we decided
to resurrect the old codebase :)
(I didn't mean the part about angry users, we love you all! :-) )
The MusE homepage is at:
http://www.muse-sequencer.org
The download is available at:
http://sourceforge.net/projects/lmuse/
Some major changes since 0.8.1:
- Working -old style- automation system, pretty much all parameters
should be automatable, audio and midi.
- Redesigned Solo/Mute system, works much better
- lots of "things" added
- lots of bugs fixed
(exchange quotations as needed)
