Re: [LAD] [ANN] guitarix-0.04.4-1 release

by James Warden

Hi Hermann, wow, I forgot to test against jack1 ... mmmm, strange, they use the same API. I have no problem at all when using it against jack2. I will investigate a bit more later today and let you know. FYI, I use jack2 svn@3540.

It seems like with the default settings I could have at least 3 instances playing at the same time. Does it hurt if it is compiled for many voices and multiple instances are run with a low voice count each? In other words, does the compile with many voices impact performance even if these voices aren't used? Personally I think that the voice limit defined at compiletime is a problem, especially if it is that low. Most distributions out there are pure binary based, so they'll have to make a choice for their users with a wide variety of machines. Some switch at application start + sane default or auto-detection would be preferable. I usually only write scripts that build from source for my distro's community repository, like this one: http://aur.archlinux.org/packages/phasex-git/phasex-git/PKGBUILD where this isn't really an issue, but we are in the process of making a binary audio repository so we face that problem as well. > > Can I pass this at configure-time somehow or do I need to sed? > > You can override the definitions at configure time by passing new > ones as debug flags to the compiler: > > ./configure --enable-arch=athlon-xp --enable-debug="-DNUM_VOICES=12" Ah, thanks a lot, I will experiment.

Definitely, this was the best purchase I did, ever. The difference is huge, now it's really a joy to listen to music, understanding lyrics, hear and feel bass, stereo image.. it's really great.

[ANN] guitarix-0.04.4-1 release

by hermann meyer

guitarix is a simple Linux Rock Guitar amplifier for jack(Jack Audio Connektion Kit) with one input and two outputs. Designed to get nice thrash/metal/rock/blues guitar sounds. . . . Some new effect's in the amp section with new controllers, overworked tuner, overworked midi output (still it is experimental but can be usefull for rhythm blues or jazz or. . . fun) Many thanks to Orcan Ogetbil (Fedora) for give the right hint to impruve the tuner, and the patch's to create a proper Makefile and more, thanks Orcan. have fun ________________________________________________________________________ guitarix based on Gtk, a great part is also realesed as ladspa plugin. guitarix is licensed under GPL Projektpage with screenshots: http://guitarix.sourceforge.net/ download: http://sourceforge.net/projects/guitarix/ For capture guitarix make use of jack_capture ver >= 0.9.30 from Kjetil S.

phasex-0.12.0-beta2

by William Weston

Announcing phasex-0.12.0-beta2 I've been away from the dev circles for a while, but I haven't forgotten about keeping phasex up to date. The new phasex beta targets all of the current build/usability issues, and includes a ton of small changes and fixes: - Clearer licensing (code and samples GPLv2, patches public domain). - Reworked JACK connection code (can now survive JACK restarts when running multiple instances). - Initial support for sampled oscillator waveforms (Juno-106 and vocal waveforms currently included). - Sound quality improvements (super-clean chorus using hermite interpolation, cleaner envelope curves, smoothing added for pitchbender adjustments, and fixes for portamento and mono keymode triggering). - New parameters (pan, lfo support for resonance, fine-tuning for osc pitch and fm). - Fixed 64 bit builds. - Added new architectures in the x86 family. - Fixed file dialog problems with newer GTK builds. - New GTK theme and color scheme. - See the ChangeLog for more... This beta aims at being a stable release. All of the currently known showstoppers have been fixed. Builds under Fedora 8 and Fedora 10 behave well with jackd and jackdmp. Builds under Debian/Ubuntu and with jackdbus have not yet been tested. Any build and crash reports would be greatly appreciated, especially from distribution maintainers. I aim to release a stable 0.12.0 in a couple of weeks, including updated patches. Check out http://sysex.net/phasex/beta to download the latest phasex tarballs and Fedora 10 RPMs. Alternatively, you can try out the new git repositoty: git clone http://sysex.net/git/phasex.git It's nice to be back working on Linux audio!

Re: [LAD] New proposal for the jackd/jackdbus mess : adding "config" API

by James Warden

the existence of ~/.jackdrc is fine and using it in the future for legacy reasons is also a good thing. Its format, on the other hand, is questionable. I don't find it a good practice to call a server configuration file something that is more some sort of shell script, because the current ~/.jackdrc is nothing but a shell script. However, I am no jack dev, so you can dismiss my opinion if you like.

New proposal for the jackd/jackdbus mess : adding "config" API

by Stéphane Letz

Hi all, Here is an updated version that add a new (to be defined) "config" API in libjack.so. The idea is to provide a way to *share* multiple server configurations in a unique place for all control application. The important point are: - we are not allowed to break legacy use of ~/.jackdrc - we absolutely want to maintain server auto-start from clients So the overall suggestion is to *maintain* this ~/.jackdrc with it's current format and to define a new config API that will probably use another file (or set of files...). - legacy control application (Qjackcl for instance) can still use their multiple server configurations, they will not see and use this new share and centralized state, but I don't think we can do better. - new control front-end (jackdbus, jackOSC) would have to use this new config API. Comments? Stephane

my take on the jack/dbus issue

by Aaron Johnson

Hi all, Where I'm coming from--I use Arch Linux, so I'm a big believer in simplicity and modularity. And CHOICE. Enforcing a Dbus dependency into an architecture that already just works fine is, I dunno, procrustean "must have Dbus" insanity. So, I agree with Fons that something like Dbus seemingly take over the whole infrastructure of my Linux system, including a key audio component like jack, is a bad idea. I also agree that this Dbus stuff seems to be creeping in as a dependency into more and more software causing all sorts of instability and havoc with whatever it touches. I can also say from 12 years of using Linux, I've never had so many error messages or instability from any other piece of my system than from Dbus-related processes. One of the reasons I now avoid the major Desktop environments as much as I can, and use fluxbox, is the feeling that they are getting too big and unstable and not 'system critical performance' enough, and I think a lot of that has to do with this incredible 'dependency creep'. So, really, from my point of view, not only should Dbus NOT have anything to do with jack, it should be taken out into the backyard and shot so we can all sleep at night.... This reminds me of Debian/Ubuntu trying to determine what Linux is. For instance, instead of adhering to vanilla practices, Debian and Ubuntu folks change file system hierarchy standards, and no wonder things break so often on those distros. I remember using both and feeling "wow this is great, lots of packages" but also..."damn, this is the 3rd reboot today--Dbus error" I'm sure I've offended someone in the Dbus-loving community. I'm sorry. You ideally should be willing to listen to reports from the field... -AKJ -- Aaron Krister Johnson http://www.akjmusic.com http://www.untwelve.org

Denemo 0.8.4 release - Music Notation Editor

by Nils Gey

Sorry for the crossposting, but the statistics show that only some people have subscribed to all three lists. ------------ The Denemo project has released a new version of its music notation program. Denemo 0.8.4, which is available for Windows, Linux and MacOS (via third-party builds) as source and binaries. The software is distributed under the GPL. Some of the new features are improvements for scripting support and user-created commands and improved MIDI-output. Official support, beneath our website, is avaible via our IRC channel #denemo on irc.freenode.net. Denemos notation-functionality is ready for daily and professional use. For future improvements our team searches for additional developers. If you are interested in notation and midi-sequencing please join the team! Website: http://www.denemo.org Additional information: GNU Denemo is a free, GPL, open source music notation editor for Linux, MacOS and Windows that lets you rapidly enter notation for typesetting via the LilyPond music engraver. You can compose, transcribe, arrange, listen to the music and much more. Music can be typed in at the PC-Keyboard, or played in via MIDI controller, or input acoustically into a microphone plugged into your computer's soundcard.
