[linux-audio-user] kfusd module (oss2jack) unknown symbols with 2.6.13

by Salvatore Di Pietro

Greets to all, I am experiencing problems during the build (and consequently modprobe) process of Kor Nielsen hacked version of kfusd module for OSS2JACK, fusd-kor-1.10-9. I am on Slackware 10.1, kernel 2.6.13 and 2.6.13.1, gcc-3.3.4, glibc-2.3.4. As far as kernel version 2.6.12.2 the module has always been built and modprobed correctly, these are excerpt from console: root@slack101-sal:/usr/src/fusd-kor-1.10-9# make . . [build output...] . . make -C /lib/modules/2.6.13.1/build SUBDIRS=/usr/src/fusd-kor-1.10-9/kfusd EXTRA_CFLAGS=-I/usr/src/fusd-kor-1.10-9/kfusd/../include modules make[2]: Entering directory `/usr/src/linux-2.6.13.1' Building modules, stage 2.

Has anyone been able to use OSS2JACK with 2.6.13 ? Thanks in advance! -- salvuz POST FATA RESVRGO Linux registered user #291700 | machine #174619 get counted on ---> http://counter.li.org/ <---

[linux-audio-user] [ANN] ALSA MIDI Kommander

by Pedro Lopez-Cabanillas

ALSA MIDI Kommander is a DCOP [1] interface exposing many ALSA Sequencer [2] features for shell scripts, Kommander scripts [3], or KDE programs requiring MIDI Sequencer services. A few MIDI utilities have been developed with this tool, which can be used both as programming examples and as real work tools. The main program, "kaseq" is a single executable, used as a DCOP service program. It runs as a daemon, allowing only a single running instance, and providing a system tray icon to give visual feedback for MIDI activity, and a way to control the program execution itself. It depends on KDE 3.x and the Qt library. More information at this provisional project site: http://kmetronome.sourceforge.net/kaseq/ Downloads http://sourceforge.net/project/showfiles.php?group_id=134956&package_id=164… Source packages http://prdownloads.sourceforge.net/kmetronome/kaseq-0.2.3.tar.bz2?download http://prdownloads.sourceforge.net/kmetronome/kaseq-0.2.3.tar.gz?download Copyright (C) 2005, Pedro Lopez-Cabanillas <plcl AT users.sourceforge.net> Released under the terms of the GNU General Public License (GPL) References [1] DCOP http://developer.kde.org/documentation/other/dcop.html [2] ALSA Sequencer API http://www.alsa-project.org/alsa-doc/alsa-lib/seq.html [3] Kommander http://kommander.kdewebdev.org/

[linux-audio-user] midi keyboard controller

by sergio

i have been looking for a midi keyboard controller to use with the linux music machine i am putting together... i would like something that fits the following description... is cheap: i am thinking of maybe spending 100 to 150 usd. works with linux: i am looking for a keyboard that has no synth or anything.. just piano keys and maybe a few programmable controllers.. smallish footprint: i don't need 88 keys.. a couple of octaves is fine. i was thinking the m audio oxygen 8 looks like a fun little gig.. does anyone know if this works with that kinda setup? does anyone else have any other suggestions? thanks! ___ peace, sergio photographer, journalist, visionary www.coffee-black.com

[linux-audio-user] [ANN] remix.linux - a creative commons enhanced audio CMS for linux audio users

by Shayne O'Connor

What is remix.linux? remix.linux provides a place for subscribers of the Linux Audio Users list to share/remix/extend/master each others work, with the freedoms offered by Creative Commons licenses. It is inspired by ccMixter and powered by ccHost. While the emphasis is on samples and remixing, anyone who doesn't have access to a webserver to put their original songs may upload complete songs here (though you are encouraged to make the seperate tracks available, too). What Can I Do on remix.linux? You can upload samples, songs, accapellas, spoken-word, remixes, midi files, flac, ogg, mp3, your sample of a duck-fart, etc, etc ... so long as they were created/recorded with a Linux Audio Application. You can rate submissions, review them, remix them, explain them, ignore them. You can stream all submissions/artists/tags, or subscribe to podcast feeds of them. How Do I Use remix.linux? Just register here: http://remix.machinehasnoagenda.com/media/register It is quick and simple and doesn't even require a confirmation email! Once you have signed up, create your profile and start uploading/downloading/remixing!!!!

[linux-audio-user] is Edirol R-1 linux friendly?

by Emiliano Grilli

Hi all, I wonder if the portable recorder Edirol R-1 (http://edirol.com/products/info/r1.html) can be used with linux. I read that is a "USB 2.0 Storage device" - (WindowsXP/2000/Me, MacOS9.2 or MacOS X, OS standard driver) so I guess it should work out of the box, but a direct experience from a linux user would fugue any doubt ;) Thank you in advance. -- Emiliano Grilli Linux user #209089 http://www.emillo.net

[linux-audio-user] LinuxSampler bug?

by Julien Claassen

Hi all! I've just recently installed the latest release of linuxsampler (0.3.3?) and I've got a problem. I only use telnet to access LS. If I want to shut the sampler down (really quit the server), it tells me something like: Stopping diskthread... There it just hangs eternally. I have to kill it. It doesn't stop my work and playing, but it is nasty and I suppose not the way it is expected to be. Anyone the same problem, fixes?

[linux-audio-user] IP audio transport

by Matt Rockwell

Greetings, I am new to the list and linux audio as I have taken over engineering a radio station. We will be building a brand new studio on campus in 2008, and I have already started to meet with the architectural committee. The more I consider our mission and where broadcast audio has the potential to go in the future, the more I find I would like to implement an open architecture infrastructure for the facility. At this point, one of the largest questions I am facing is the transport of the audio around the plant, and potentially around campus. The UW has invested a tremendous amount of effort in building a multicast capable infrastructure to handle communications needs of the campus into the future, so we will certainly have pipeline available if we wanted to get data from point a to b. The question is what type of transport would be capable of interfacing with what type of in-house switching and routing? The in-house needs would be a system capable of replicating something along the lines of what Z-sys:http://www.z-sys.com/pp_routing.html equipment is capable of providing. My first choice would be to replicate this type of routing in software as well [JACK on a large scale]. The question then leads into what will be the transport method? Cobranet http://www.peakaudio.com/CobraNet/Background.html is certainly promising with actual market availability, but it is still proprietary. I ultimately envision a system where an artist (DJ) sits at a terminal and has the capability to patch their own inputs with ALSA and JACK, bring everything up on a control surface for tactile use, and route to air, stream, or file. I welcome any comments in any form which anybody wishes to contribute. I will also continue to form my train of thought here: http://mattrock.net/WSUM/. Thanks to you all for providing an environment which has been long overdue to the audio world.

[linux-audio-user] csound5 lpc question

by Julien Claassen

Hi! I'm trying to get some tests with lpc done with csound5. The problem I have is: my csound5 doesn't have it's own lpanal, so I used lpanal of csound4.23.something. it runs fine and outputs its analysis-frames. But when I run a simple test, it only outputs to cracks with a lot of silence in between. My orchestra looks something like: [header] instr 1 ktim line 0, p3, p3 a1 buzz 15000, 110, 64, 1 ; function 1 is a sine GEN09 krmsr, krmso, kerr, kcps lpread ktim, "voice.lpc" aout lpreson a1 out aout endin The audio-material, which I analysed was simple speech. Am I doing something wrong? Should I be sure to use one of lpanal's options to get good input for lpread/lpreson?
