Hi :) I have this problem too: http://ardour.org/node/2271 If I go back to the Suse 11.0 version before 0.116, it's 0.109, the message changes from "jackd: symbol lookup error: jackd: undefined symbol: clock_source" to "jackd: symbol lookup error: jackd: undefined symbol: _jack_get_microseconds". I tried to write with the German community (at Linux-Club Suse and Packman community) about such issues, but they aren't interested in their bugs and because they laugh about me, I'm not interested anymore to report anything to them. Everything I tried to inform about, should be wrong they say and laugh and there were a lot of bugs similar to that one, for audio and MIDI realtime applications from the standard repositories Oss, Non-Oss, Updates, Packman and VideoLAN. Also there are often versions that aren't good for professional work. I removed the jack package by YaST2 and then ... suse11:/usr/lib # rm libjack* suse11:/usr/lib64 # rm libjack* After I installed jack again, I got "jackd: error while loading shared libraries: libjackserver.so.0: cannot open shared object file: No such file or directory". Does anybody know a Suse community that is interested to solve those things? I'm fine with the Debian 64 Studio audio community. Isn't there such a friendly community for Suse (not JAD)? For some reasons I like to use Debian 64 Studio and Suse, but Suse often is a pain in the arse, because of a narrow views having community. Do I need to compile jack myself for Suse 11.0? Before I upgraded jack, I don't get any error messages. Cheers, Ralf

[ANN] LADITools 1.0-rc1 released

by MarcO'Chapeau

Hi all, After quite some time spent doing nothing, a lot of polishing from Nedko, a lot of suggestions from Kfoltman, and absolutely no effort from me to make things go faster... I am very proud to announce the first release candidate of LADITools 1.0 code name "flabbergasting-mademoiselle-sitting-on-my-hat" (yeah... I bought a new hat for those who wonder) LADITools is a set of tools aiming to achieve the goals of the LADI project (http://nedko.arnaudov.name/wiki/moin.cgi/LADI) to improve desktop integration and user work-flow of Linux audio system based on JACK and LASH. Those tools take advantage of the DBus interfaces recently added to JACK and LASH to ease the configuration and use of those two great softwares. Ok, sounds good... but what does it really do ? LADITools is a software suite containing various utilities to make your life a little easier when working with JACK and LASH clients. You will find in this suite : * The laditools python module (no interest for the end users) * laditray : a system tray icon that allows you to start, stop and monitor JACK, as well as start some JACK related apps (log viewer, connections...) * wmladi : a controller as a Window Maker dockapp. Uses the same menu as laditray * ladilog : a JACK, LASH and a2jmidid log viewer * ladiconf : a GUI to setup JACK's configuration * g15ladi : a JACK monitor for g15 keyboards You can download it from the LADITools homepage here : http://www.marcochapeau.org/software/laditools. Some updated screenshots will be made available soon. As far as docs and bug reporting are concerned, you'll have to come and ask on #LAD or #jack about it :) My thanks go to Nedko Arnaudov who is the brain hidden behind this plan to take over the world using DBus interfaces, Krzysztof Foltman who tests, suggests and code a lot more than I do, a lot of people from IRC who also made suggestions and contributions for the past year, and of course, the whole set of JACK/LASH developers who accepted to have a DBus control interface get into their repo :) Cheers, -- Marc-Olivier Barre -- --- MarcO'Chapeau ---- - www.marcochapeau.org -

Softsynths from Java

by Richard Just

Hey there, I have a Java app that can output Midi and I want to be able to access softsynths on a Linux system. Is there already a project out there that does such a thing? Would it be best to interface with Ladspa or Jack? Any info would be greaty appreciated! Richard

[ANN] QjackCtl 0.3.4 is out!

by Rui Nuno Capela

hi, A semester has gone by, since last release, with no big news on this front. Alas, on the verge of the coming one-dot-oh release of the mighty JACK Audio Connection Kit, here goes one fine update of its old and aged Qt GUI front-end: QjackCtl 0.3.4 is out! Nothing much new to see but you might welcome the patchbay snapshot revamp, which might finally do the right thing, and the rand new translations that are getting in place: German (de), Spanish(es), French (fr) and Russian (ru). Many thanks to all involved. With no further ado, the good stuff is ready from the usual places. Website: http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Download: http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.4.tar.gz Weblog: http://www.rncbc.org License: QjackCtl is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: 0.3.4 2008-12-05 Patchbay snapshot revamp. - Introducing the very first and complete translations in-package: German (de), Spanish (es), French (fr) and Russian (ru); credits in TRANSLATORS. - At last, after years of retarded procrastination, the old infamous patchbay snapshot feature has been the subject of a almost complete rewrite and it does try to give a way better mapping of all actual and current running client/port connections, both JACK (audio, MIDI) and ALSA MIDI, of course ;) - On Setup/Settings/Parameters dialog, all device selection options are now reset to default when disabled interactively. - Grayed/disabled palette color group fix for dark color themes. - Qt Software logo update. - Fait-divers: desktop menu file touched to openSUSE conventions. - ALSA PCM devices now only listed/enumerated iif strictly compliant with the audio mode criteria (Duplex, Capture-only or Playback-only) as kindly suggested by Nedko Ardaunov. - JACK client/port aliases may now be displayed as a global user option (see Setup/Display/Connections/JACK client/port aliases). - Lighten up the connections line and highlight colors, as seen to fit best on some darker background themes. - Patchbay snapshot fixed to differentiate socket clients according to its type (Audio, MIDI or ALSA-Seq), avoiding the mess and gross mistake of hanging disparate type ports under the same client item. - JACK_DEFAULT_SERVER environment variable is now appended to the X11 unique application identifier, allowing for having multiple instances each controlling its own JACK server, besides the default one. - Due to some trouble with newer Qt >= 4.4 applications regarding font size configuration, a new global user option is now available to the rescue: Setup/Misc/Defaults/Base font size (default is no-op). Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc at rncbc dot org

IM like GUI for netjack

by torbenh＠gmx.de

hi... now that the backend is mostly done, i am thinking about a GUI for netjack. i already found gtknetsource.py on my HD, i started mucking with that some months ago. i plan to extend that thingy now. but setting up the connection, and getting IP addresses of users is still a PITA. i am thinking along the lines of an IM like thing, based on jabber. i am not seeing good options to making this available in the various IM clients. thats why i would rather like to have modified jabberd running on jackaudio.org or at the consortium servers. it would not support chatting or stuff. only show who is online. and if a session is running. it would only make the IP of a user available when he agrees, to open session... blabla... security. so basically you click on your buddy, to open a session. buddy agrees. IP of buddy is transmitted. tool measures connection. provides you with some options. ie compression ratio, number of channels, latency, who is master ? and starts the netjack session. thoughts ? -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

[ANN] zynjacku version 2 released

by Nedko Arnaudov

In this release: * zynjacku codebase updated to the latest state of LV2 art. Especially, event MIDI port synths are now supported. * The tarball now contains lv2rack - a host for LV2 effect plugins. * Saving/restoring of presets. Does not work for dynparam plugins yet. * LASH support (autodetected at runtime). * Lot of general fixes that should make zynjacku more usable. I would like to thank Krzysztof Foltman for adding support for some LV2 extensions and Martin Raspaud for helping with slv2 compatibility during my LADI quest. zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK MIDI input port (routed to all hosted synths) and one (two for stereo synths) JACK audio output port per plugin. Such design provides multi-timbral sound by running several synth plugins. zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid parts for synthesis itself and you have flexible part that allows synthesis to suit your needs. lv2rack is a host for LV2 effect plugins. You need slv2 library, Pyhton bindings for PATH and lv2dynparam host library to compile zynjacku tarball.

ASUS mobo NEW thread - started OT for another tread

by Ralf Mardorf

In reply to Subject: Re: [LAD] Audio vs ASUS M2N-SLI Deluxe mobo Date: Sat, 29 Nov 2008 08:55:17 -0500 From: Gene Heskett Organization: To: Ralf Mardorf CC: linux-audio-dev lists.linuxaudio.org References: <200811290046.51317.gene.heskett verizon.net> <4930F02B.5030109 alice-dsl.net> Hi Gene :) before it gets too confusing, I'll isolate the ASUS mobo audio and ASUS mobo MIDI issue. I got another reply off-list about the MIDI issue. Here it is, including my answer: Subject: Re: [LAD] Audio vs ASUS mobo - MIDI Date: Sat, 29 Nov 2008 14:34:42 +0100 From: Ralf Mardorf To: References: wrote: > On Sat, 2008-11-29 at 08:32 +0100, Ralf Mardorf wrote: > > >> If I try to use MIDI applications like Rosegarden, Qtractor and soft >> synth like Qsynth (using an USB MIDI IO device and a Envy24 based sound >> card) I only get crashes. >> > > I got that on kernel 2.6.26-rt when I upgraded from 2.6.24.

I tested Suse 11.0 with the distro's real-time kernels, not with the Jengelh once. Suse 11.0 at the moment is 2.6.25 and I tested 64 Studio 2.1 with the default real-time kernel 2.6.21 and a self compiled real-time kernel 2.6.24. I know that the ASUS M2N-SLI Delux has another chipset than my ASUS M2A-VM HDMI, but because both mobos are relatively new, there might be something in common. MIDI applications crashes without any useful messages for my ASUS M2A-VM HDMI with an AMD BE-2350 CPU using Suse 11.0, 64 Studio 2.1 default (Etch) and 64 Studio 2.1 upgraded to Lenny. Another user has a Gigabyte ga-p35-ds3l with an Intel q6600 CPU and the same problems, he now runs Windows for MIDI work, but started with 64 Studio, Arch and Sidux, he also tested different kernels. His mobo is fine with XP, Cubase SX and Halion, 100% stable. I don't have any Windows install for my computer, so I don't have any information about this. For my mobo Linux is stable for any thing else, but MIDI applications, resp. when I try to run MIDI applications, often their audio clients, resp. JACK fails. I still hope it will be possible to solve the problem. I have the latest BIOS version for my mobo. Until now I only tested 64-bit distros and never a 32-bit version. What mobo, CPU and distro do you use? Thanks, Ralf
