Forwarded, sorry for the cross-posting: The JackLab Project announces its first public release Promotion association planned The technical manager of the JackLab of project, Oliver Bengs, released the final 1.0 version of the JackLab Audio Distribution (JAD) today after development period of over eight months. JAD 1.0 is based upon OpenSUSE 10.2 with the addition of a real time Linux kernel for fast audio processing with the professional audio server JACK. JackLab 1.0 includes one of the most comprehensive selections of open source audio and multimedia software to date. The Enlightenment D17 window manager (with 'KDE-lite' tweaks) is used by default, with the option of using the full KDE 3.5.7 instead. JAD 1.0 aims to lower the Linux entry barriers, making things as easy as possible for musicians and multimedia content creators, and it offers complete compatibility with openSUSE 10.2. The Smart package manager is included for quickly and easily updating or adding new software and the YaST system tool is included for easy graphical system administration. The system is immediately operational after installation for tasks such as multi-track recording with Ardour 2, real time audio synthesis with ZynAddSubFX , MIDI sequencing with Rosegarden, video editing with KDEnlive, and graphics manipulation with programs such as Inkscape and Gimp. Unlike most other existing Linux audio distributions JAD 1.0 offers complete support for ASIO. Thanks to WINE you can useWindows VST host programs such as Reaper or EnergyXT2 with a very large number of VST plugins, with latency as good as native Linux JACK audio applications. Simply add the wineasio driver to the WINE registry and these applications can then be used as easily as if from native Windows. This is all easily done and well-documented on the JackLab wiki. In addition, native VST for Linux is supported by JOST, a powerful modular host. Some native Linux VST plugins are included with the distribution but there are more that can't be included for legal reasons. JOST also supports LADSPA, the native Linux Audio Developer plugin format. JackLab comes with over 300 LADSPA plugins. JAD 1.0 is the result of a collaboration of musicians and free software developers and enthusiasts. This community was started by musician and media producer Michael Bohle in order to improve and promote the development of pro-audio under Linux. OpenSUSE was selected as the basis of JAD because it is a very user-friendly version of Linux. The project is independent from OpenSUSE but intends to give back to the community by improving SUSE's support for pro-audio and multimedia creation. In order to safeguard JAD and its future development, a registered promotion association [JackLab e.V.] is planned. JackLab e.V. will sponsor activities of the JackLab community such as workshops, participating in shows, and holding developer conferences. Hopefully it will also fund the development of exciting open source audio projects. The project would like to thank all the testers and early adopters for their assistance in creating JAD 1.0, along with all the good discussions in blogs, forums and magazines. The overwhelmingly positive response from musicians was very encouraging. We received feedback from the whole world, where JAD 1.0 is now used in recording studios, schools, workshops and youth centers.

But I don't know if it would work well with a regular package manager (in terms of packaging work, updates, etc.). Stefano

ladspa qa?

by Tim Blechmann

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 -- tim(a)klingt.org ICQ: 96771783 http://tim.klingt.org Desperation is the raw material of drastic change. Only those who can leave behind everything they have ever believed in can hope to escape. William S. Burroughs

alsa seq client ids??

by IOhannes M zmoelnig

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? mfg.asdr IOhannes PS: i guess this question might be more appropriate on one of the alsa lists, but since i am subscribed to lad and not to one of these, .... PPS: sorry if this comes through 2 times; i originally sent this email from an non-subscribed account...

No Timidity Development for the last 3 years

by Carlo Florendo

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 -- Carlo Florendo Softare Engineer/Network Co-Administrator Astra Philippines Inc.

[OT] assembler guru needed

by Dave Phillips

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[2]: Leaving directory `/home/dlphilp/src/wine-0.9.44/libs/port' 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, dp

LADSPA Windows OR Effects on all three major systems.

by N. Gey

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
