Re: [LAU] [Rosegarden-user] [Rosegarden-devel] Fwd: Rosegarden's Future

by david

I believe that some of the people involved are, at least college-level educators. The English index is here: http://www.musix.org.ar/en/index.html When I try to go there, at the moment, I get a piece of garbage text; viewing source shows this heading in the source:  The Portuguese page is working fine: http://www.musix.org.ar/index.html Here's a page in their wiki with download links for Musix 3 beta: http://www.musix.org.ar/wordpress/?cat=16 On 05/18/2012 03:54 AM, David Tisdell wrote: > Musix is created by educators?

[LAU] Ambient quasi-Persian music

by Brett McCoy

New track I recorded not too long ago, sequenced with Rosegarden, recorded/mixed with MixBus, with some live guitar and flute and loops & samples via Kontakt. Uses a lot of elements from traditional Persian music also. http://soundcloud.com/brett-mccoy/evolution-of-the-ifritah -- Brett W.

[LAU] Mac Mini? (or, am I an idiot?)

by Josh Lawrence

Hi again list, sorry so noisy lately - I've got a Mac Mini. It's really nice, was bought late last year, 8 GB RAM, fast processor, etc. I love OS X, but I really, really, really miss Linux. I've been enjoying Tango Studio (an Ubuntu derivative), and would like to install it on my Mac Mini. Is this stupid? >From what I've been reading, getting this to work is a mix of BootCamp and rEFIt (http://refit.sourceforge.net/). Has anyone done this, and if so, what was the experience like? Thanks list. Josh

[LAU] Batch Convert .wav to .ogg and .mp3 with tags

by Ivan K

Over the next few months, I will need to convert a large number of .wav files to the .ogg and .mp3 formats. Because of the large number of files, I need to do this with scripts rather than with a tool like audacity. Sox works with the .ogg format fine but when trying to convert to an .mp3 file I get the message: /usr/local/sox-14.3.1/src/.libs/lt-sox FAIL formats: no handler for file extension `mp3' I realize that the mp3 format is proprietary, but I have the libmp3lame library installed which allows audacity to work with mp3 files. Is there any way that sox can be configured with this library to work with mp3? Or is there tool other than sox that people recommend? Also, it would be very useful when doing these conversions from .wav to .ogg and .mp3, to be able to set some of the tags in the header. Thank you for your help;

[LAU] [ANN] QjackCtl 0.3.9 quietly emerges...

by Rui Nuno Capela

Guess what...? the last of the remnants quietly emerges :) QjackCtl 0.3.9 has been released, finally! Website: http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Downloads: - source tarball: http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9.tar.gz - source package (openSUSE 12.1): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.sr… - binary packages (openSUSE 12.1): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.i5… http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.9-1.rncbc.suse121.x8… Weblog (upstream support): http://www.rncbc.org License: QjackCtl is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Killing D-BUS controlled JACK server is now made optional, cf. Setup/Misc/Stop JACK audio server on application exit. (a patch by Roland Mas, thanks). - Added include <unistd.h> to shut up gcc 4.7 build failures. - Make(ing) -jN parallel builds now available for the masses. - A mis-quoting bug at the command line argument string may have been crippling the (unmaintained) Windows port since ever, leaving its main function to start jackd dead in the water, belly down :) now hopefully fixed (following a mail transaction with Stephane Letz and Mathias Nagorni, thanks). - Currently a JACK2-only feature, the JACK version string display at the About dialog box, must now be explicitly enabled on configure time (--enable-jack-version). - A new so called "Server Suffix" parameter option appears to rescue on the situations where QjackCtl falls short on extra, exquisite and/or esoteric command line options eg. (net)jack1/2 differences. - Fixed D-Bus Input/Output device parameter settings, filled when either interface is selected for Capture/Playback only. (probable fix for bug #3441860). - Fixed Makefile.in handling of installation directories to the configure script eg. --datadir, --localedir, --mandir. (after an original patch from h3xx, thanks). - Main window is now brought to front and (re)activated when clicking on the system tray icon instead of just hiding it. - Add current xrun count to the system tray icon tooltip, if not zero (after patch #3314633 by Colin Fletcher, thanks). Enjoy && Have fun! -- rncbc aka Rui Nuno Capela

[LAU] Muse beta?

by Brent Busby

Just wondering what those who use Muse sequencer think of the beta 2.x release versus 1.x for usability/stability...or would it be best to stick with 1.x for actually getting projects done for now? -- + Brent A.

[LAU] Surround Sound

by Mac

I'm looking around for a way to get surround sound into a PC and be able to route it with JACK. So there are two parts: - What physical connection is needed on the PC (i.e. I have a blue ray player or cable box spewing surround sound...maybe hdmi?) Any body have experiences with particular interface cards? - What software goes between the hardware above and JACK? Ideas? Comments? Recommendations? Thanks, Mac

[LAU] Track Cue List, "Red Book" CD Mastering, and CD burning

by Kevin Cosgrove

Hi all, I need to master an audio CD of a live concert. I'm doing the mixing in Ardour, and that's going just fine. But, I have questions for some upcoming steps. - In the export section of Ardour (I'm using 2.8) I've seen stuff about exporting CD markers, or something to that effect. How is that used? - I need to burn a CD that's got song markers, but no gaps because that sounds strange (to me) in a live show. Is that controlled by Ardour, or the burning program, or both? How? - What Linux CD burning program(s) can make use of the CD cue info exported by Ardour? - I need to make my master CD conform to "Red Book" standard. What Linux CD burning program(s) will do that? One thing I'm told about "Red Book" standard, for instance, is that track one starts at -2.0 seconds, with the audio beginning at 0.0 seconds. I don't have to do as many steps in Ardour as I've indicated. It would be nice to use as few tools as needed. If another program between Ardour and CD burning, e.g. Audacity, makes the overall job easier, that's fine by me. Any advice people? Thanks... -- Kevin

[LAU] USB on ThinkPad T520

by plutek

greetings! i've been running AVLinux5.0.3 on a ThinkPad T61p for a while now.... with an ART USB Dual Tube Pre, i can run Jack at 64 frames, 2 periods (2.9msec latency), and run a puredata test patch of mine with almost no xruns -- maybe 1 per hour or so. now i've got a new ThinkPad T520, and if i start jack on USB at 64*2 i get hundreds of xruns in seconds. to run the same test patch without crashing, i have to go up to 256*2 (11.6msec). i've tried stopping a bunch of processes, and unloading kernel modules (mostly related to wireless and networking, and the hald-addon-storage polling), but it makes no difference. on both machines, i always lock the CPU's at max speed, and kill screensavers and DPMS. any help on where to look to solve this would be most appreciated! cheers! .pltk.

[LAU] Very frustrating problem with JACK and exporting through mixbus

by Jason Jones

Hey guys.. I recently acquired a RME Raydat interface (works like a *charm*, and I love it!), but ever since I installed it, I'm getting a random error when I try to export my tracks, and it's driving me bonkers. Previously to installing the Raydat card, I had used ardour for approximately 10 years, and have never experienced this problem. The problem is about 75% of the time, when exporting, the GUI will just sit there and do nothing, maintaining the "export" button depressed continually. Within QJackctl's "message" window, I see the following error: JackEngine::XRun: client = ardour was not run: state = 2 JackFreewheelDriver::Process: Process error 00:31:20.920 XRUN callback (1). The remaining 25% of the time it exports just fine, without issue. Needless to say, this is extremely frustrating. Googling the problem returns nothing but the snippet of code which contains the error message itself, which can be found at the link below: http://www.trac.jackaudio.org/browser/jack2/branches/pipelining/common/Jack… Any help would be greatly appreciated. If more info is needed, please let me know what I can get you. Also, thanks to everyone who assured me that the Raydat card works well under Linux. It really does work like a charm.
