Hi, I was a long term jackd1 user and my first action on a new linux installation (mostly using Ubuntu) was normally to remove pulseaudio as it was badly configured and/or buggy. Things have changed and I really started to like PA for everyday stuff. And then jackdbus came along which together with the device reservation API and the jackd sinks promised to make using these two things together more easy. This mostly works fine, except for the device reservation bug in PA which is easy to work around though: - Make sure no audio process is actively using the soundcard you want jackd to use - Run pulseaudio -k - Run jack_control start I have noticed some issues with jackdbus though: a] jack_control start sometimes doesn't work at all after the first time it failed to aquire the device. A killall -9 jackdbus is in order to restore it b] after some hours of operation jackdbus starts to eat 100% cpu on two of my four cores. Are these known issues? I use Ubuntu 12.10 and jackd: fps@mango 12:08:21 .../Games/Xonotic/ $ jackd -v jackdmp 1.9.9 [...] How to diagnose the 100% cpu thing more closely? The ~.log/jack/jackdbus.log shows nothing suspicious. Thanks and regards, Flo -- Florian Paul Schmidt http://fps.io

[ANN] Vee One Suite 0.3.1 - One second bug-fix release

by Rui Nuno Capela

hello there, a new batch of the Vee One Suite of old-school software instruments, primarily slated for Linux, featuring synthv1 [1], a polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], a drum-kit sampler, are on the loose now. as previously, they come in a couple of expressions, such as: - a pure stand-alone JACK client with JACK-session and both JACK MIDI and ALSA MIDI input support; - a LV2 instrument plugin. interesting changes for this bug-fix release are: - improved filters parameter sensitivity (cutoff, reso). - envelope generators stage curves now gone a little more old-schooler and analog-like, hopefully improving on the punchy and click-less sound front. - experimental LV2 Time designated port support (Delay BPM). - preparations for Qt5 migration. - sample loop points were missing the LV2 UI state restoration. (samplv1) all are free, open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. enjoy the Carnival!

[ANN] Sqorlatti 0.1.3-b (music notation editor)

by M Donalies

Currently, it's just for display and editing. There's no playback yet. And it's still pre-alpha, so you can expect it to crash without expending too much effort. Just a few bug fixes. I've included the changelog to 0.1.3 as well, since the announce didn't make the list. If all goes well, the next release should be sometime in March. Website: http://sourceforge.net/projects/sqorlatti Download (bzipped source tarball): http://downloads.sourceforge.net/sqorlatti/Sqorlatti-0.1.3-b.tar.bz2 Changes in Sqorlatti 0.1.3-b: * Fixed bug when trying to edit data in Score Dialog. * Set initial background color of Staff Editor to white. Changes in Sqorlatti 0.1.3: * Converted configure/build system to cmake. See the INSTALL file for more information. * Added default tab tunings for std guitar and bass to Score. * Added combo to select tab tuning to track dialog. * Cleaned up some C-style casts and fixed some sloppy code involving const. * Added edit modes (select, insert, and delete) to StaffEditor. * ToolBar in StaffEditor with common note durations. For use in insert mode. * Allow add/remove notes to chords and tuplets. * Cleaned up Staff Editor drag & drop a little. There's still not much consistency checking, though. * Added some user preferences, in particular, Staff Editor font size and background color. These preferences get stored in $HOME/.config/Sqorlatti (the usual place for Qt to put QSettings data). On the initial run, you probably want to change the Staff Editor background color. You can do this through the main window menu Tools->Preferences->Staff Editor. Known problems: * cmake cleanup not very good when doing in-source builds. * Undo for inserting events and containers through MasterView not combined into a macro, so separate commands are issued for insert and edit. It's not really wrong, just inconvenient and confusing. * Editing tab tunings not yet implemented. -- 7:8

Re: [LAD] [LAU] So what do you think sucks about Linux audio ?

And my library drumstick-file is available under a free license, offering this functionality to any interested developer. For me, this says everything about the worse problem in the Linux audio development community. Regards

Mudita24 release 1.1.0

by Tim E. Real

Hello. I finally rolled an archive. This is for the benefit of ye kind packagers out there, and everyone, as I notice the version in Ubuntu for example is still the old version which has broken alsactrl profile support - can't save/load profiles. There has been no changes to code for a while, except that I just now removed the SVN version from the About page. However, the most recent major changes from a while ago are important, such as profile fixes, and are not in the last release, so it is important to get this release out there. Mudita24 is a modification of the Linux alsa-tools' envy24control(1): an application controlling the digital mixer, channel gains and other hardware settings for sound cards based on the VIA Ice1712 chipset aka Envy24. Project home page: http://code.google.com/p/mudita24/ Download source code: http://mudita24.googlecode.com/files/mudita24-1.1.0.tar.gz Let us know if any problems. Thanks. Tim. The Mudita24 project. The MusE project.

NASPRO 0.5.0 released

by Stefano D'Angelo

Hi all, Here comes a new release of NASPRO, 0.5.0 this time. No new features, just bugfixes and "regular" updates. The components being updated are: * NASPRO core: untested fix for semaphores on Mac OS X, build system fixes; * NASPRO bridge it: build system fixes; * NASPRO bridges: dynamic manifest URIs changed, updated LRDF-equivalent data matching newest CAPS releases, build system fixes; * LV2proc: fixed bogus warning w.r.t. lv2:sampleRate ports, updated manpage, build system fixes. ino, gino and FreeADSP have been undergoing experimentation in the last months and their future is uncertain at this point. Enjoy! Stefano
