It seems Dennis Ritchie [1] passed away last week end. He was the inventor of the C programming language and core developer of UNIX. I guess we are all relying in some way or another on this man's research and inventions in our 'contemporary computer lives'. Lorenzo. [1] http://en.wikipedia.org/wiki/Dennis_Ritchie

Client connection to JACK fails with socket error -- help?

by Simon Kalteis

Hello all! My name is Simon, I am a long-time user of JACK on Debian-based Linux systems. I prefer to compile JACK myself so I always set the JACK-packages in Debian to "hold", remove everything from /usr and put my build into /usr/local. Starting with Debian 6.0 "squeeze" (Kernel is 2.6.38-1-686 #1 SMP), this seems to cause problems somewhere. I checked out jackdmp from SVN yesterday, build was ok. jackdmp starts up, QJackCtl is able to connect and the connection graph shows up. But any other client I want to use with JACK causes the following error: [snip] Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started [/snip] My test client of choice is mplayer. (SVN r3418) I checked whether the runtime linker uses the correct libs: /usr/local/bin/mplayer libjack.so.0 => /usr/local/lib/libjack.so.0 (0xb718a000) This should be ok. The list of file descriptors for the running jack server is [snip] jackd 13063 simon cwd DIR 8,6 36864 146594 /home/simon jackd 13063 simon rtd DIR 8,6 4096 2 / jackd 13063 simon txt REG 8,6 22899 223189 /usr/local/bin/jackd jackd 13063 simon mem REG 8,6 145629 236929 /usr/local/lib/jack/jack_alsa.so jackd 13063 simon mem REG 0,16 82493164 2070826 /dev/shm/jack-1000-0 jackd 13063 simon mem REG 8,6 1153328 391304 /usr/lib/libasound.so.2.0.0 jackd 13063 simon DEL REG 0,16 2995543 /dev/shm/jack-1000-2 jackd 13063 simon DEL REG 0,16 2995541 /dev/shm/sem.hTRyxy jackd 13063 simon DEL REG 0,16 2070960 /dev/shm/sem.2Jamky jackd 13063 simon mem CHR 116,5 241895 /dev/snd/pcmC0D0p jackd 13063 simon mem CHR 116,6 241896 /dev/snd/pcmC0D0c jackd 13063 simon mem REG 8,6 1323460 246009 /lib/i686/cmov/libc-2.11.2.so jackd 13063 simon mem REG 8,6 116600 228035 /lib/libgcc_s.so.1 jackd 13063 simon mem REG 8,6 149392 245993 /lib/i686/cmov/libm-2.11.2.so jackd 13063 simon mem REG 8,6 30684 245999 /lib/i686/cmov/librt-2.11.2.so jackd 13063 simon mem REG 8,6 9736 246001 /lib/i686/cmov/libdl-2.11.2.so jackd 13063 simon mem REG 8,6 117367 245998 /lib/i686/cmov/libpthread-2.11.2.so jackd 13063 simon mem REG 8,6 958479 223178 /usr/local/lib/libjackserver.so.0.1.0 jackd 13063 simon mem REG 8,6 975012 214075 /usr/lib/libstdc++.so.6.0.13 jackd 13063 simon DEL REG 0,16 2070886 /dev/shm/sem.5FWprn jackd 13063 simon mem REG 0,16 1012 2070831 /dev/shm/jack-1000-1 jackd 13063 simon mem REG 0,16 70712 1906270 /dev/shm/jack-shm-registry jackd 13063 simon mem REG 8,6 113964 228057 /lib/ld-2.11.2.so jackd 13063 simon 0r FIFO 0,8 0t0 2070809 pipe jackd 13063 simon 1w FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 2w FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 3u CHR 116,7 0t0 241899 /dev/snd/controlC0 jackd 13063 simon 4u unix 0xece16900 0t0 2070957 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 5u CHR 116,5 0t0 241895 /dev/snd/pcmC0D0p jackd 13063 simon 6u CHR 116,6 0t0 241896 /dev/snd/pcmC0D0c jackd 13063 simon 7u unix 0xece166c0 0t0 2070959 socket jackd 13063 simon 8u CHR 116,1 0t0 2555 /dev/snd/seq jackd 13063 simon 9u unix 0xece16000 0t0 2070962 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 10u unix 0xf4c71200 0t0 2995537 /dev/shm/jack_(default)_1000_0 jackd 13063 simon 11r FIFO 0,8 0t0 1906200 pipe jackd 13063 simon 12w FIFO 0,8 0t0 1906200 pipe jackd 13063 simon 13u unix 0xf4f81440 0t0 2995542 socket jackd 13063 simon 17r FIFO 0,8 0t0 1906224 pipe jackd 13063 simon 18w FIFO 0,8 0t0 1906224 pipe [/snip] So the server apparently has sockets open -- question is why are clients except QJackCtl unable to connect to them? I am out of ideas. I basically recompiled everything from source a few times (including alsa-lib, libsndfile, jack, mplayer) and nothing changed. I appreciate any help on this problem. Thank you very much in advance! Simon --

LV2 AMS Plugins (0.0.2)

by Aurélien Leblond

Hi Guys Just posted on Sourceforge a new version of these plugins. I added: - a CV to Hz convertor and Hz to CV (seems to be working ok, the VCO is now in tune) - The VCA module from AMS (called VCA Lin and VCA Exp) - The ENV module from AMS With those, it should be possible to create very simple modular synths in Ingen. >From the few test I have done, things seems to be working fine, but feel free to provide any comments and feedbacks! The file can be downloaded from here: http://sourceforge.net/projects/avwlv2/files/ Aurélien

That's weird, the error is in the lv2-c++-tools... I might have something missing but I can't figure out what... Anybody that can help?

LAC 2012 - Save the date: April 12-15 at CCRMA/Stanford University

by Bruno Ruviaro

Save the date! Linux Audio Conference, April 12-15, 2012 @ CCRMA/Stanford University The Linux Audio Conference (LAC) is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse programme of music. The upcoming 2012 conference will be hosted at CCRMA, Stanford University, on April 12-15. Stay tuned for more details on how to submit your work online. The website will be up and running by mid-October. The Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University is a multi-disciplinary facility where composers and researchers work together using computer-based technology both as an artistic medium and as a research tool. CCRMA has been using and developing Linux as an audio platform since 1997. http://ccrma.stanford.edu Stanford is located in the heart of Silicon Valley, about one hour south of San Francisco, California. This is the first time LAC will take place in the United States.

[ANN] rtirq update

by Rui Nuno Capela

greetings, rtirq, the init script that automagically tunes up your system for audio, has been updated as much for better avoid duplicates when alsa device drivers share their irq line with something else. here you can find the upstream tarballs: http://www.rncbc.org/jack/#rtirq or, this very latest: http://www.rncbc.org/jack/rtirq-20111007.tar.gz nb. rtirq only applies to preempt_rt or threadirqs enabled kernels (>= 2.6.39) byee -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

LV2 AMS Plugins

by Aurélien Leblond

Hi everyone, I posted the first version of some of the internal AMS plugins ported to LV2. So far, only the following have been ported: - Analog Driver - Amp - LFO - Noise2 - VCF - VCO2 Please note that the code is extremely raw, and so far I think it makes sense only to run these plugins in Ingen. Any comments or advises, feel free :) Oh, and here is the URL: http://sourceforge.net/projects/avwlv2/files/ Aurélien

Re: [LAD] Internally representing pitch : A new approach

by Jeff McClintock

Don't base anything on 7-bit MIDI, it's too low-fi for a modern system, plus it's keyboard-centric (i.e the concept of each note 'stuck' at a single pitch is too restrictive). Plus it's being replaced by hi-def MIDI. My suggestions: * Use at least 32-bit floating point to represent pitch to give high accuracy. * Base pitches internally on octaves. E.g. 440Hz = 'octave 0.0', 880Hz = 'octave 1.0' etc. An octave is a fundamental unit of pitch which is not biased to any particular tuning system. Don't use plain frequency in Hertz, Hz are very un-musical because they do not scale the same way as our ear perceives pitch. * Separate the concept of 'key number' and 'pitch' (MIDI seems to confuse people on this point). A key-number is NOT pitch and vice versa. This is so you can... * Support two 'keys' playing the same pitch, this is critical for stringed instruments like guitars. * Support 'bending' pitch on each note independently. * Support the concept of re-triggering a voice that's already playing, this is important for any percussive instrument. E.g. hitting a cymbal twice in quick succession should not trigger the sound of two cymbals playing together. Best Regards, Jeff SynthEdit
