[linux-audio-user] Low latency with 2.6.16.16 vanilla

by Wolfgang Woehl

Hi, I want to try what Lee mentioned a couple of times recently: Low latency audio performance with 2.6 mainline -- no mingo-patch, no rt-lsm (athlon xp 2600+, asus a7v8x-x, hdsp. On a 2.4.26 with lck patches this system has good lowlat performance, solid jackd with -p 64 -n 2, so the hardware should be ok. Ah well, looong dropouts on deep reiserfs walks that never show up in jackd's messages but that's hopefully another story). Got 2.6.16.16 from kernel.org. If I understood Lee right I could expect a jackd with -p 64 -n 2 to work just fine but it doesn't. Loads of xruns. What am I missing? What can I do to find out? With make oldconfig I come across some questions I'm unsure about. Are these answers right? Thanks in advance. # IO Schedulers # CONFIG_IOSCHED_NOOP=y CONFIG_IOSCHED_AS=y CONFIG_IOSCHED_DEADLINE=y CONFIG_IOSCHED_CFQ=y CONFIG_DEFAULT_AS=y # CONFIG_DEFAULT_DEADLINE is not set # CONFIG_DEFAULT_CFQ is not set # CONFIG_DEFAULT_NOOP is not set CONFIG_DEFAULT_IOSCHED="anticipatory" --- # Processor type and features # # CONFIG_HPET_TIMER is not set # CONFIG_SMP is not set # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set CONFIG_PREEMPT=y CONFIG_PREEMPT_BKL=y --- # Firmware Drivers # # CONFIG_HZ_100 is not set # CONFIG_HZ_250 is not set CONFIG_HZ_1000=y CONFIG_HZ=1000 --- CONFIG_SND_RTCTIMER=m CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y -- Wolfgang

[linux-audio-user] music notation

by glauber alex dias prado

hello im new to this list, how this is the first time let me introduce myself, im 23 years computer graphic fan and also a music fan, i live in brazil and have one kid and a woman that i love, if someone wants to know more about me you can visit my messed site www.greboide.dahora.net (im still getting the hangs on web producing but im not too much worried about it now). Now im not a musician and this is a skill that i dont know if i can get one day, for now im looking for some info on making midi scores to composite together with my 3d videos that i do using blender. I would really aprecciate if someone could give me some directions on learning these things, first im considering buying a midi keyboard that i consider will make it more dynamic than using the virtual keyboard or a notation editor like the one at rosegarden. i have a relative good system here to make this and most apps are running and i already made some sound/music but nothing that worth it, the apps that i got running and think that can be usefull are theses: jackd ardour xjadeo(for video synchronized playback) jack-rack and ladspa plugins zynaddsubfx jack-dssi-host (fluidsynth,xsynth and hexter) clavier and vkboard freewheeling hydrogen rosegarden perhaps there is more but i think that these ones are enough for now otherwise it can get too much complicated. so my general question is where can i find composing infos like tutorials or whatever but the most important to me is make my own music or perhaps make a partnership with one but i would really like to be able to compound it, thanks for those who can give me some directions.

[linux-audio-user] experience with doggiebox

by Julien Claassen

Hi all! Sorry for crossposting, but I wasn't sure, who could answer it more apropriately. Does anyone of you ever have had experience with doggiebox http://www.doggiebox.com Is the format of their drumkits known? It seems to me this software is kind of free. And they seem to have a few nice and free kits. Thus I thought perhaps one could convert them to hydrogen or soundfont. It looked straight forward enough. Any ideas, hints, whatever? Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net - the Linux TextBased Studio guide

[linux-audio-user] [ANN] OpenJay needs you! Help request

by J_Zar

Hi to all Linux Audio Users / Developers... I would like to stress my help request so I forward this mail to give some more attention... OpenJay.org is an opensource DJ site where you can find information and programs for djing and playing music with opensource software. OpenJay.org has been established 3 - 4 years ago. OpenJay.org has been recently updated to the Joomla web platform. The new graphic design has been coded by me around some past artwork of Ayo [http://www.73lab.com] (thanks Ayo!). During the upgrade there were some data which I can't save: unluckily the whole download repository. This is not necessarily a bad thing: repository was outdated and somewhere broken. However the point is that I really need some help to build it again. So I ask you to consider the idea of registering an account at OpenJay.org and submitting downloads that you know in the proper categories (Please do! Please!). (Please, use file upload only if needed! If not needed link to the download page of the item...) But this is not the only thing I need. I'm looking for people... and probably...for you! Hereunder, the short list of people and things I'm looking for... - users to reconstruct and improve the download repository - 1 or more moderators for the Forum - 1 or more operators for the IRC channel - 1 or more article / news contributors and software testers You should consider the following notes: - the more we are, the better it is; - duty and help may be discontinue and this is a personal promise not a contract! - OpenJay.org does not require a 24h duty but probably a couple of hours per week and no more Please help me (and you at the same time)! ;-P Ciao -- ---------------------------- Gianluca Romanin (aka J_Zar) ---------------------------- OpenJay.org Webmaster ----------------------------

[linux-audio-user] Interesting Tidbit: The Midas XL8 uses Linux

by Jordan Nash

According to the May 2006 edition of Pro Audio Review (Page 12, Column 1, Paragraph 3), the Midas XL8 Digital Console uses Linux: "Like many other devices these days, the XL8 is built on a Linux platform, which has proven to be both stable and secure, compared to other common operating systems." I just thought that it was a bit interesting. Anyone want to take bets on how long it will be before DigiDesign switches over? ;-) Links related to this: http://proaudioreview.com/ http://www.midasconsoles.com/xl8.html -Jordan

[linux-audio-user] jack crash in alsa_driver_run_cycle

by c

so i figured i'd finally try to get jack working. since maybe in the past year something has changed to make it not crash after a minute or two of use.. trying to build with portage FEATURES="nostrip" CFLAGS="-ggdb" USE="debug" jack-audio-connection-kit-0.100.7 or 0.9999, compilation fails here: /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: .libs/alsa_driver.o: relocation R_X86_64_PC32 against `alsa_driver_run_cycle' can not be used when making a shared object; recompile with -fPIC without the -ggdb and debug, it will compile, but it crashes in the same or similar function mentioned above... this is with gcc-4.1.0 and alsa 1.0.11, on an ATIIXP/Turion and EchoMia/Athlon64. both running 2.6.16 or .17 (non -rt) with stock config and ALSA disabled in the kernel.. interestingly , compiling everything (jackd, alsa-lib, alsa-driver, glibc, and any jack-using apps) with gcc-3.4.6, the crashes happen much less, but still occasionally. in the kernel messsagelog it says something like (pid 23234: trap divide), where 23234 is the pid of jackd.. this has been happening ever since i switched to amd64 and ive never found a solution...any ideas?
