[linux-audio-user] HELP! udev fails at boot after plugging in MIDI keyboad on CCRMA

by Link Swanson

I just got a cheap "Quickshot MIDI Composer" MIDI keyboard and plugged it into my RME HDSP/MultifaceII. I had the keyboard powered on at boot and udev took longer than usual and then said "FAILED" and stops the entire boot process. I have no idea what to do, as I am a noob. The frightening thing is that I need to export four hours of High School choir and band recordings that I did with Ardour and need to be done tomorrow by 8:00a.m. or I won't get paid and the students won't have a CD to take with them as they finish the year. I need to get this done tonight but my system won't boot past "starting udev" If anyone knows what to try, THANK YOU! Link

[linux-audio-user] ecasound interactive mode

by Paul Coccoli

How do you add a second chain in ecasound in interactive mode? I can create one chain that reads a file for input and outputs to jack, but if I try to add another chain I get the following: ecasound ('h' for help)> c-add t2 (eca-control) WARNING: This operation requires that chainsetup is ... disconnected. Temporarily disconnecting... - [ Engine exiting ] ----------------------------------------------------------- (eca-control-objects) Disconnecting chainsetup: "command-line-setup". - [ Chainsetup disconnected ] -------------------------------------------------- (eca-control-objects) Added chains: t2. (eca-chainsetup) Unable to connect: Chain "t2" is not valid. Following errors ... were detected: (eca-chainsetup) Chain "t2" is not connected to any input.

(2.2-NO-CHAIN-OUTPUT) ERROR: Can't reconnect chainsetup. Well, ok, so then I quit, restart with 1 chain again, THEN create new input and output, and try to create a second chain: ecasound ('h' for help)> ai-add jack_auto (eca-control-objects) Added audio input "jack_auto". ecasound ('h' for help)> ao-add jack_auto (eca-control-objects) Added audio output "jack_auto". ecasound ('h' for help)> c-add t2 (eca-control-objects) Added chains: t2. ecasound ('h' for help)> c-list t1,t2 ecasound ('h' for help)> start (eca-chainsetup) Unable to connect: Chain "t2" is not valid.

Hmm. If a chain MUST have one valid input and output, but inputs and outputs need to be connected to a chain, THEN ITS A PARADOX AND MY HEAD EXPLODES! Seriously, I'm tryin the most basic thing in the world and I can't do it. Maybe it's just too late at night... paul

[linux-audio-user] lost recording capability of my soundcard

by The Quibbler

I don't know what happened. Less than a month ago, I could record, now I can't. Playback works, and I can hear the input through the speakers. It just doesn't get recorded. I think the problem started after a debian sarge update of KDE. I've played with every button in KMix, but nothing resolves the problem. I can't record from any imput source, no matter which I select in KMix. Can someone please point me in the right direction? It's a dual-boot system. I can bring up Windows, and record fine, so there's nothing wrong with the card. I'm using 2.6.10 kernel with ALSA, and it's a SB Live! card. And, as I said, everything was working fine a short while ago, so some setting must have changed somewhere. The weird thing (and maybe a key clue to you all) is that playback works fine.

[linux-audio-user] Music: Awakening the Avenger with percussion

by Thorsten Wilms

Hi! http://www.archive.org/details/avenger Folderol/Terry Blunt/Will J Godfrey's Awakening the Avenger in a mix with somewhat busy percussion by yours truly :) Questions and comments welcome, including sugestions for a more descriptive ... description on the Archive page. Thanks to Will for letting me work with his great material. Thanks to all involved in the nice tools used (Rosegarden, ZynAddSubFX, MusE, Timemachine, Sweep, Patchage, Om and many LADSPAs) and all the infrastructure. Special thanks to Dave Robillard for Om, making me forget my drum sample collection ... Oh, and to Loki for showing me via Smack how to get more out of it ;) Best, Thorsten Wilms

[linux-audio-user] An experimental version of Musix 0.49 will be available in a few hours/days

by Marcos Guglielmetti Gmail

An experimental version of Musix 0.49 will be available in a few hours/days Main features: * kernel 2.6.16-beyond4.1 (it might support installation in SATA hard drives) * knxinstaller -optional- (advanced installer taken from Kanotix distribution) * 460 updated software packages * ALSA 1.0.11 audio drivers for kernel 2.6.16-beyond4.1 * Note: kernel 2.6.16-beyond4.1 does not have the realtime patch from Ingo Molar applied, but its performance is quite good (it was tested). "Beyond4.1" refers to a series of patches that were not applied to the traditional kernel yet (vanilla). Musix 0.49 will at least give hardware support for new sound cards, etc. We hope you can test it and report errors or success. Musix 0.40 is much more tested, and we suggest to use this version in long-term if you do not have hardware detection problems. Musix 0.49 is thought for those who have new computers and/or hardware compatibility problems. -- Marcos Guglielmetti * Director del desarrollo de Musix GNU+Linux, 100% Software Libre * Descarga el CD de Musix: (www.musix.org.ar) (www.pc-musica.com.ar/musix) * Videos, programas y otras cosas en: ftp://musix.ourproject.org/pub/musix/

[linux-audio-user] Nord Modular Editor in Wine

by Michael Wagner

Hello there, I have searched the archives to find out, if it is possible to run the Nord Modular Editor from within wine and transfer patches from / to the Nord MicroModular. Unfortunately I haven't found any useful information. The editor itself seems to be working. The MIDI-Interface in Setup -> MIDI shows up as well, when I click one of the enable checkboxes (well, there are no port numbers showing up (every (physical) port has the same name), so i cannot assure that I chose the right ports; I have a MOTU MIDIexpress XT, by the way), but as soon as I click "Apply", the wine process goes into uninterruptible sleep state. Is it actually possible to connect the NM1 / MicroModular with the editor in wine? Has anyone managed this? Thank you very much in advance. -Michael

[linux-audio-user] Indentity change?

by Folderol

I was somewhat dismayed to find that both my e-mail handle and given name are extremely common on the net, and I'm somewhat concerned at the prospect of possible confusion as other musicians, DJs etc are included. I have taken to using the name Will J Godfrey on all ID tags for my music, and on my homepage title. It will probably take a while to change all the existing files. Eventually I'll move the website too, but will maintain a link for the foreseeable future. This is just to let you know so you won't think one of 'me' is being ripped off! -- F

[linux-audio-user] Generating x frames of silence wav.

by Alex Polite

I need to programatically pad a wav file with x frames of silence. I figure the best way of doing is to generate a wav file containing x frames of silence and concatenate the generated file with the original. Problem is I don't know how to generate the silence. The method I'm using now feels kind of backwards. I generate two sine waves that are phase shifted in relation to one another and then I mix them so that they cancel one another out. sox -t nul /dev/null /tmp/tmp1.wav synth $secs sine create 1 0 0 sox -t nul /dev/null /tmp/tmp2.wav synth $secs sine create 1 0 50 soxmix /tmp/tmp1.wav /tmp/tmp2.wav /tmp/tmp3.wav sox /tmp/tmp3.wav -r 8000 /tmp/silence.wav I guess there's a more elegant way of doing obtaining the same result? I'd also like to be able to specify the amount of silence to be generated in frames rather than in seconds. -- Alex Polite http://flosspick.org - finding the right open source

[linux-audio-user] Quatafire 610 and freebob: recent news?

by Jose Henrique Padovani

So: I have visited six motnhs ago the freebob site and became very curious about Quatafire 610 under linux... The site has not changed to much since then. Any news? It would be a very nice interface to use in any system. (linux, mac, win...) I have particular interest in intercative music on Puredata then low latency would be a important thing.. Another thing that would be nice know is if anyone knows about freebob integration on Debian based distros like Ubuntu. I thanks anyone that has news or sugestions (not RME, please: to high prices on my country). J.H. _______________________________________________________ Abra sua conta no Yahoo!
