[linux-audio-user] DeMuDi unusable on widescreen nVidia LCD

by Jon B

I have tried this twice. I install DeMuDi, and the installer works fine, but then when it actually tries to run, it SCREWS UP HARDCORE. The screen turns into nothing but purple and teal vertical lines. The first time I knew nothing about linux and gave up. The second time was today. I cleared out some room and made a new partition to experiment with distros, since my current system is very crash-prone and unorthodox. I know a little bit more this time, so I pushed ctrl+alt+F1 to get the regular prompt. But even that is screwed up, with black and white vertical lines everywhere. I can kind of see through them to read what I am typing, but not very easily. I have a (mostly) working low-latency-modified Libranet install on another partition. Maybe I could copy my XF86Config from there? Also I need the nVidia drivers, however, which would require my network card to be functional. I also need network card drivers to get my network card functional, which would require my network card to be functional. :-) It is a non-fun adventure! Any advice? For the Libranet install, I got the nVidia working with the Libranet installer here: http://libranet.com/support/2.8/0365 and got the network card working with the Libranet installer here: http://libranet.com/support/2.8/0316 (downloaded in windows and then opened in linux). More info about my installation here: http://mysite.verizon.net/negatron/linux/libranet8600.html Perhaps a suggestion for another distro / distro modification? (Feel free to point me to instructions instead of writing them out.) A 2.6 kernel would be nice, so I can have the integrated ALSA and low-latency, and so I can write to NTFS partitions, but none of the debian music distros seem to use it. Why is that? I like the idea of debian handling dependencies for me, but it hasn't really handled them that well in practice. I am not apt enough to fully get apt-get, I guess. So I would consider another package system, although I fear the alternatives are even scarier. Hmmmm... I could use LIbranet (or mepis or something?) to install a minimal system, dist upgrade to debian unstable, and then upgrade to demudi, right? That might be my best option...

[linux-audio-user] [ANN] LACommunity goes gentoo...

by Arnold Krille

Hi all, if you are not a gentoo user stop here, otherwise read on. All the english linux-audio-lists please accept my apologies for crossposting to german gentoo list. [DE: Gentoo-user-de, bitte vergebt mir das Crossposting an die Englischen Listen.] Today I decided to make my little but constant gentoo-portage overlay available for the public. It contains only some apps not in already in portage. Currently available are aeolus-0.3.1 with aeolus-stops-0.1.1, fmit-0.9.[89], museseq-0.7.0, tuneroid-0.9.4 and (not an linux-audio-app) ktechlab-0.1.2. You can access the repository via svn, the address is: http://roederberg.dyndns.org/svn/apps/portage-arnold/ If there is interest, I could also create a tarball, just ask... Feel free to use it and feel free to send patches or to apply for write access. Currently I am trying to follow the anounces on this list, filter away the apps, where gentoo.org is fast enough and add the remaining into my repo. The chances are better if I personally use this app. :-) Thanks for your patience, Arnold PS: [EN: This will be the last time I do such a crossposting. Promised!] [DE: Das ist das letzte mal, das ich so ein Crossposting mache.

There is another theory which states that this has already happened. -- Douglas Adams, The Restaurant at the End of the Universe

[linux-audio-user] [ANN] QjackCtl 0.2.14 released!

by Rui Nuno Capela

Hi, QjackCtl 0.2.14 has been released. No big features, only a bunch of optimizations and cleanups. Check it out: http://qjackctl.sourceforge.net From the change log: - Put a limit on XRUN callback messages and statistics report rate, preventing the potential hosing of the GUI due to a XRUN cascade storm. The maximum reasonable report rate has been fixed to be one XRUN callback occurrence per second. - Set to ignore the SIGPIPE ("Broken pipe") signal, where available, as the default handler is usually fatal when a JACK client is zombified abruptly. - All conection view items are now sorted in natural case insensitive order, not just as audio port names as was before. - Got rid of those nonsense paranoid and rather stupid pseudo-mutex guards on the connections management framework and event notifications (nuff said :). - Optional confirmation warning on audio server shutdown, if there's some audio clients still active and connected (as suggested by Sampo Savolainen). - Check for <jack/statistics.h> on configure time (as of JACK 0.99.42+ CVS). - "Unlock memory" server setup option was added, allowing the release of memory used by common toolkit libraries (GTK+, Qt, FLTK, Wine) that were being superfluously locked on every GUI JACK client; number of periods has now the minimum allowed value of 2; server start delay widget converted to spinbox; setup dialog layout slighly changed. - Removed stand-alone usx2y driver support. Since JACK 0.99.41+ CVS, the special "rawusb" support on the Tascam US-122/224/428 USB Audio/MIDI interface controllers have been merged and properly integrated into the regular alsa backend driver. Being still experimental, this special mode of operation is now triggered only when "hw:N,2" is specified as the alsa device name (N = soundcard index of snd-usb-usx2y module). - Messages window limit is now enforced only when the line count exceeds in one third the user configured line count maximum; if Qt 3.2.0+ is in use, the QTextView widget is otherwise set to the optimized Qt::LogText format. - XRUN status items are kept double-dashed if none has been detected. Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-user] new synths rumored to be based on Linux

by Florin Andrei

Hot news from NAMM 2005 - it is rumored that the Alesis Fusion and the Korg Oasys (both demo'ed to the public for the first time at this NAMM) are actually using Linux under the hood. http://www.fusionsynth.com/ http://www.korg.com/gear/product_info.asp?a_prod_no=OASYS&category_id=1 Here's a video demo of the Fusion synth: http://www.sonicstate.com/news/shownews.cfm?newsid=1924 Pretty impressive: all the major synthesis techniques (sampling, virtual analog, physical modelling, FM), plus an 8-track sequencer, plus a 40GB hard-drive. More stuff from the NAMM: http://pigpendigital.com/namm2005 -- Florin Andrei http://florin.myip.org/

[linux-audio-user] linuxsampler cvs from this weeks compile problem

Hi! I just downloaded linuxsampler cvs at the beginning of this week.

[linux-audio-user] [ANN] MIDI to CSV Utilities 1.0

by Pedro Lopez-Cabanillas

Not a long time ago, somebody asked in Linux-audio-users mailing list for a commandline utility allowing MIDI to text conversion. I'm proud to introduce you a set of tools from John Walker, who wrote and released it into the public domain. I'm not involved in this project, only commissioned to announce and spread the truth ;-) There are two main programs: midicsv converts MIDI files into CSV (comma separated values) text. The complementary work is done by csvmidi. The CSV text is a very readable format for humans, and easy to process by Perl scripts (or any other suitable programming tool). Several simple Perl scripts are included showing how to do common tasks as transpose, extract and generate MIDI sequences from scratch. This software is well documented and bug free. It can be compiled for *NIX, and WIN32 systems. Direct download: http://www.fourmilab.ch/webtools/midicsv/midicsv-1.0.tar.gz More information: http://www.fourmilab.ch/webtools/midicsv/ Regards, Pedro

RE: [linux-audio-user] [OT] Switching workspaces or ping-pongingscreens?

by Henry Camacho

I highly recommend getting the two screens, or even three. I run 3 monitors here on windows, and I use Cygwin/X for windows to get a graphical desktop to my linux host. It works fairly well. HFC -----Original Message----- From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio-user-bounces@music.columbia.edu] On Behalf Of Christian Frisson Sent: Tuesday, January 04, 2005 3:15 AM To: linux-audio-user(a)music.columbia.edu Subject: [linux-audio-user] [OT] Switching workspaces or ping-pongingscreens? Heyall, I'm up to throw my little and only 15" CRT screen in the attic to replace it by a more space-friendly and hum-bucking 17" LCD screen. I heard that running a dual-screen workstation is very fashionable for musicians (or artists): the sequencer on the first and the mixer on the second for example. Thus I was wondering whether I should take advantage of the opportunity and buy two of them at the same time, from the same brand, same model, same series... to avoid being disoriented. But doesn't Linux enable us to switch virtual workspaces with a single key combination? So what's better: flicking keys or ping-ponging eyes? Wrists RSI's or strabism? Cheers, Christian
