Folks, Yesterday I did some improv using ardour2. I got a few tracks and wanted to save them in a .wav so I can listen to them easily. Unfortunately, as it turns out, I closed ardour2 and restarted it hoping to load my fresh project and make the .wav. But ardour2 segfaults while trying to load what I was working with for the past hour ! With this error: loading bindings from /etc/ardour2/ardour.bindings Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkWidget::cursor-color' of type `GdkColor' from rc file value "((GString*) 0x154d520)" of type `GString' Loading session /Share/Compotes/c26/c26 using snapshot c26 (1) Erreur de segmentation What's mind-boggling, in a Windows-shareware way, is that it cannot load what it was working with before. Now I can see it from here. Blame GTK. OK, what else ? Blame Fedora ? Blame the moon. The bit bucket in the sky. Apart from that, is there a solution to get these tracks )eg. project) back if only to be able to listen to them again ? Thanks for any suggestions. On the fun side of things, here's some 45 seconds I did last year, right after buying the audio stuff for the machine: http://www.geocities.com/alf32967/ Cheers.

Fwd: Hardware Choices

by Thomas Vecchione

I apologize if this goes out twice, I sent the first copy to the wrong LAU address, forgot about the server switch. Ok so later this week I get the final paycheck that will enable me to upgrade my Linux box some. At the moment it is running a single, single-core 1.6 GHz Opteron with a gig of ram. It has two CPU sockets Assuming a budget of around $500 I can get either... 2x 2GHz Dual Core Opterons ($420) 1 More Cooling Fan for the second processor ($30-$40 for the Zalman I am looking at) and maybe another gig or two of ram. or... 1x 2.4 GHz Dual Core Opteron ($380) And at least a gig of ram And a possibility of another SATA HD I am curious as to people's opinions as to what will fit better. I believe I heard Jack (jackdmp?) could only take advantage of two cores right now? Which makes me wonder if the dual dual-core option is even worth it at the moment? I would imagine it would help by offloading WM and similar to a third core, but honestly running e17 and a dedicated audio workstation means I don't have to worry much about that. Would it help with multiple instances of Jamin even if jackdmp doesn't support more than 2 cores or should I just got with the single higher clock speed dual core processor? The first thing this would get used for: At the moment I have a project I am working on and hoping to finish up by the end of August (Sorry due to copyright issues I cannot release it to the list as much as I would love to). This project consists of 24 tracks at 24/96. I am pushing the single HD I have for it, but I might be able to rearrange it down to a smaller track count for most of it, and for the rest once it gets going it is fine when it caches the audio into memory. With the amount of plguins I am running though the CPU is getting pushed hard, and there probably won't get reduced to much, I am looking at moving around seperate vocalists to allow the use of Jamin's scene preset to use this instead of a single band compressor on some of the vocals, would require two instances, instead of individual single compressors and eqs on each vocalist, to help prevent me from having to reset every function on the compressors and eqs by hand repeatedly, the scene function is very nice and Jamin contains the Compressor and EQ I would be ptuting there anyways, but obviously draws more power. The vocalists come and go(Live theater performance recording, cast of 13), often individual or in duets to quads, but occasionally in a large full cast number as well, thus the using the scene function to allow me to get multiple vocalists on the same track and cut down on overall processing maybe, but also to cut down on overall track count in most places. Thanks in advance for the help. Seablade

A new song using Qsynth/Steinway IMIS, Ardour, Zynaddsubfx on Musix

by Marcos Guglielmetti

Download from: http://www.musix.org.ar/ogg/tmp/Miles_de_lagos_MF7_master+6db.ogg Hi, This is my first song using the Freepats's Steinway IMIS soundfont (ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2), and my second one recording my acoustic drum live (not hydrogen sencuenced), the Colombo one. Mixer console: Phonic MU 802 I used 5 mics for the drum, but all the drum went into the 2 channels on my SB Live! soundcard, I splited the bassdrum and snare from the rest of it:crash,ride, and toms. The acoustic guitar it is a Mirr's made in China, recorded from line and mic, the MIDI keyboard controler it's a Kawai Spectra (i hate it). I used a SAMSON C 05 condenser Mic to record all I could: voices, guitars, ambient (drums). The bass and some distorted guitars are from Zynaddsubfx (attached). uname -a Linux Musix 2.6.21.5-rt18 #2 SMP PREEMPT RT Fri Jun 29 19:55:08 EEST 2007 i686 GNU/Linux Total number of Ardour's tracks:19 Well, and, oh, the Lyric: "Miles de lagos en mi mente, esperan tu voz y cuando llegue, será un rio Hago cosas para que la gente venta a mí, pero yo nunca iré hasta vos Soy como un equilibrista que hace los trucos que te gusta ver y oir, oh Y cuando llegues, no hará frío Puede el primer pétalo de primavera alcanzar mi pecho y descansar En el bosque me he dormido y unas aves han dejado un nido en tu lugar.

[ANN] QjackCtl 0.3.1 (unstable-qt4) is out!

by Rui Nuno Capela

Greetings y'all, Just one week after a no-regrets migration, here comes this second iteration over the Qt4 framework for the JACK Audio Connection Kit "cutie" GUI front-end that everybody loves or at least ought to :) QjackCtl 0.3.1 (unstable-qt4) is out! The main feature on this release, besides for the bug-fixes, is that it's the very first time ever QjackCtl is made available to build and run on all major desktop platforms: X11/Linux, Windows and Mac OS X. Yes you read it right, Windows, and it is thought to behave consistently on all those. One just have to take advantage from the Qt4 open-source edition and license which in fact is the same as QjackCtl's: GPL2. Yes, there's no turning back. QjackCtl is definitely a Qt4 application, this release marking the departure from the old, aged Qt3 code base, despite this one being tagged as "stable-qt3" anyway. The current branch has "unstable-qt4" on its middle name still, but not for long ;) Being a so-called shallowed bug-fix release, the change-log says some thingies that were shoved out, and nothing about the ones that still are creepin': - The current DSP load percentage activity is now also displayed on the system-tray icon tooltip. - An illusive but nasty Connections/Patchbay item tooltip crash bug has been hopefully fixed (Qt >= 4.3). - Now using QSystemTrayIcon class facility if available (Qt4 >= 4.2) making the system-tray option available on most platforms, notably on Windows and Mac OS X (EXPERIMENTAL). - Usage of QProcess class has been severely refactored, now using QProcess::start() instead of QProcess::startDetached(), giving much tighter control over the started jackd(mp) process. Downside is that QjackCtl lost its ability and option to leave the process detached upon quitting the application. Too bad. - A new eye-candy bit has sneaked in: server mode display, that is the RT indicator, now blinks when server/client is started/active. - Combo-box setup history has been corrected on restore, which was discarding the very initial default (factory) contents. - Now that Qt4 is accessible to open-source Windows appplications, there's some experimental stuff sneaking in for jackdmp support on win32 (http://www.grame.fr/~letz/jackdmp.html). - Connections list items were initially sorted in descending order by default. Fixed. Client items are now naturally sorted, again. As usual, the source tarball might be found here: http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl Cheers && Enjoy, -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

qjackctl: cannot set 44100 sample rate from 48000 default -- Planet CCRMA with Fedora 6

by Luis Cordova

Hi, I cannot cannot set qjackctl sample rate from 48000 default to 41000 in my Planet CCRMA with Fedora 6. See below.

[ANN] Qsynth 0.3.1 (unstable-qt4) released!

by Rui Nuno Capela

Greetings, So after the great Qt4 migration, which was almost couple of weeks ago already, here comes the so-called shallowed bug-fix release of this "cutie" FluidSynth GUI: Qsynth 0.3.1 (unstable-qt4) has been released! As said, some bug-fixes have popped in and others are still hidden in the closet. Notable changes were: - Now using QSystemTrayIcon class facility if available (Qt4 >= 4.2) making the system-tray option available on most platforms, notably on Windows and Mac OS X (EXPERIMENTAL). - Combo-box setup history has been corrected on restore, which was discarding the very initial default (factory) contents. - One programming error has been corrected, which was affecting the editable preset combo-boxes usability. - Soundfont context menu is now available again even when the setup dialog soundfont list is empty. - About form link is now browseable externally. - Updated README-OSX (thanks to Ebrahim Mayat again). Grab it while it's hot: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth Enjoy && Cheers, -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
