"A Passionate Tribute" is a 3 song EP made in Linux. You can hear that on bandcamp: https://lotfi.bandcamp.com/album/a-passionate-tribute-ep or download the tracks from: http://carlorat.me/carpenter.flac http://carlorat.me/fulci.flac http://carlorat.me/bava.flac This is totally hobbystic, I made it just for fun, in my home. My setup looks like this: http://i.imgur.com/9cpuZLe.jpg And yes, the amiga is playing as a soft synth in some part. The acoustic drums were recorded in another house, and they are these: http://linux-audio.4202.n7.nabble.com/A-short-story-from-zero-to-recording-… Here is a couple of words about song meanings: http://carlorat.me/quote/apassionatetribute/ Cheers -- Carlo Ascani | carlorat.me skype: carloratm irc: carloratm@freenode

Slow but pitch-correct video playback

by Philipp Überbacher

Hi there, I encountered a nice piano learning video including hands and animated keys, but since it is playing at original speed it is way to fast for me to learn that song. In case anyone is interested, it's this video and I think it's rather nicely done (don't hate me for the music :P): https://www.youtube.com/watch?v=Ej6MF5KjuOc I found one way which sort of works (after settings LADSPA_PATH) but it sounds quite horrible. Is there a better way to do this? http://markplusplus.wordpress.com/2006/10/01/pitch-correct-play-speed-with-… Is there a stretchplayer for video? Regards, Philipp

Problems with real time kernel, thermal throttling and cpu freq governors.

by Rafael Vega

Hi all, I'm re-posting this issue here since there are more real-time kernel users here than in other lists/forums and I'm hoping to get attention into this issue. In short, when running the RT kernel from Debian Jessie repos (3.14-2-rt-amd64), the scaling governor cannot be changed and the system hangs if the cpu temperature reaches the thermal throttling threshold. More info here: http://forums.debian.net/viewtopic.php?f=5&t=117613&p=554270#p554270 Has anyone experienced this issue? Anyone else running that kernel version from the Debian repos? Any other RT kernels for Debian out there that I could test? Thanks! -- Rafael Vega email.rafa(a)gmail.com

express card on new laptops

by Len Ovens

Is expresscard the slot that can have a firewire interface? It seems that some of the "rugged", "milspec", (expensive) laptops like this one still have it: http://www.dell.com/us/business/p/latitude-7404-laptop/pd?p=latitude-7404-l… I was actually looking to see if there were laptops that came with plugs with a high insertion cycle rating.... but there is no mention of that. -- Len Ovens www.ovenwerks.net

Re: [LAU] [LAA] Announcing LibreMusicProduction.com

by Bent Bisballe Nyeng

(Sorry for bluntly moving this thread to LAU list for my reply) Thank you very much for the amazing site. I think this more or less exactly what this community needs (and maybe the result of you questionaire from a while back Gabriel?). One thing I would very much like on the site is a subscription for email notification on new articles. Would this be possible? I know you explicitly asked for feedback to go through the forms on the website, but I figured this might be of interest to others in the LAU community as well.

Current way to get ZASF as a plugin?

by Phil CM

Hi everyone I'd really like to be able to finally use the new and shiny ZynAddSubFX in Qtractor (latest from source). I tried the "zynaddsubfx_dssi" but even ghostess could not start it: ⚡ ghostess /usr/lib/dssi/libzynaddsubfx_dssi.so ghostess: ghostess starting... ghostess: failed to load plugin library /usr/lib/dssi/libzynaddsubfx_dssi.so Then I build the full monty using the latest source tar.gz on SF <https://sourceforge.net/projects/zynaddsubfx/files/latest/download?source=f…>, because I could not get the git master branch <https://sourceforge.net/p/zynaddsubfx/code/ci/master/tree/> to compile (I'm using Ubuntu 14.04 with 3.13.0-36-generic). Now ghostess does load something ⚡ ghostess ~/src/zynaddsubfx-2.4.4/build/src/libzynaddsubfx_dssi.so ghostess: ghostess starting... ghostess: instance 0 on channel 0, plugin 0 is 'libzynaddsubfx_dssi/ZASF/inst00' ghostess: listening using ALSA MIDI ghostess ready I get a small window with just a "UI" button ; when clicked, it reveals a window with a "Send test note" that works! :) Just a sine wave "a" but still. There are "bank" & "program" menus, but they don't seem to work. In Qtractor, I get basically the same thing, without the test sound :/ It seems to be lacking both UI definitions and instruments. I also tried building Carla and puttin bin/carla.lv2 in my lv2 dir, carla showed up in qtractor LV2 tab but failed to load with suil error: Unable to wrap UI type <http://kxstudio.sf.net/ns/lv2ext/external-ui#Widget> as type <http://lv2plug.in/ns/extensions/ui#Qt4UI> [31mexec failed: No such file or directory[0m read() returned 0 force killing misbehaved child 11048 (start) [31mCarla assertion failure: "fPipeSend != -1" in file ../../utils/CarlaPipeUtils.hpp, line 422[0m [31mCarla assertion failure: "fUiServer.isOk()" in file CarlaEngineNative.cpp, line 935[0m [31mQVariantMap DBusMenuExporterDBus::getProperties(int, const QStringList&) const[0m: Condition failed: action (...) How can I link all this together? Wow, I'm on it since early this morning!? Thanks to anyone who's listening. Phil PS - I tried the "zynadd" package (can't find the sources/repo) w/o any luck PPS - WAIT! I missed the " ZynAddSubFX" entry in the LV2 list! This is from Carla (I tested it by trying to remove the carla.lv2 dir) ; It does load (and a song save / qtractor restart yeld no error) only I can't neither load a new instrument (I cloned the instrument repo <https://sourceforge.net/p/zynaddsubfx/instruments/ci/master/tree/> and selected the dir as the default) nor seem to affect the sine sound playing (I turn the knobs, say ADSR in *edit instrument* and nothing changes)) so now I don't have ZASF but can see it from where I am :) Thank you for your patience.

QMidiArp-0.5.2 released

by Frank Kober

Hi, QMidiArp 0.5.2 has just seen the light of the day. It brings mainly two improvements. One is a comeback, that of tempo changes on the fly, and that now includes also tempo changes of a potential Jack Transport master. Also the Jack Transport starting position is finally taken into account, so that QMidiArp should be in sync also when starting the transport master not at zero. The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen! Note that for compiling in NSM support you will now need liblo as dependency. Enjoy, and enjoy LAC in Graz this year Frank ________________________________ QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. Everything is on http://qmidiarp.sourceforge.net qmidiarp-0.5.2 (2013-05-09) New Features o Tempo changes are again possible while running, both manually or by a Jack Transport Master o Jack Transport position is now taken into account when starting, QMidiArp used to start always at zero o Muting and sequencer parameter changes can be deferred to pattern end using a new toolbutton o Modules in the Global Storage window have mute/defer buttons o Global Storage location switches can be set to affect only the pattern o Non Session Manager support with "switch" capability (thanks to Roy Vegard Ovesen) General Changes o NSM support requires liblo development headers (liblo-dev package)

[ANN] Super Announcement - All MOD software for your PC

by Gianfranco Ceccolini

Hello Linux Audio Users and Developers In less than an our the MOD Duo Kickstarter campaign will go live and so it is with great pleasure that the MOD Team makes the announcement of the desktop versions for our entire software suite. Some of this software has already been announced in the past but, as part of our Kickstarter campaign, we put the necessary effort to have them running in a regular Linux environment and not just inside the MOD. All instructions in Github were also updated in order to yield working elements when followed. Most of this software has been under development for almost two years and their history is related to the development of the MOD itself. Being so, they carry some differences in workflow when compared to other LV2 programs and our current effort is being put on correcting those differences. The softwares are: MOD Client - run your LV2 plugins using the MOD interface. https://github.com/portalmod/mod-client —————————————————————————————————————————— MOD SDK - plugin interface creator Use this program to create the HTML interface required by the MOD Client. If you don’t create an interface the plugins still work, but their icons will be a tuna fish can with just the ON/OFF button. When you click on the gear symbol on the upper right side of the icon you have access to the Plugin Settings Screen in which all parameters are visible. The MOD SDK is Python based and can be installed by typing “pip install modsdk” As the MOD Client, it runs on your browser and requires a mod-workspace folder (or link) in which you place your LV2 bundles. Just run “modsdk" in your terminal and point your browser to localhost:9000 There is also post on our blog about the SDK: http://portalmod.com/blog/2014/09/the-mod-sdk —————————————————————————————————————————— LV2BM - tool for analyzing and benchmarking LV2 plugins Allows to select which URIs to test Uses minimum, maximum and default control values to run the plugins Uses several controls combinations in the full test mode The output shows the JACK load percent —————————————————————————————————————————— Plugins - CAPS-LV2 LV2 port of the CAPS suite of LADSPA plugins. - TAP-LV2 - LV2 port of the TAP suite of LADSPA plugins. - Pitch shifters - http://github.com/portalmod/mod-pitchshifter Capo - up to 7 semitones up pitch shifting SuperCapo - up to 24 semitones up pitch shifting Drop - up to 12 semitones down pitch shifting SuperWhammy - continuous pitch shifting from -12 to 24 semitones Harmonizer - scale interval generator - Utilities - https://github.com/portalmod/mod-utilities Switchbox - A/B box for audio signal routing SwitchTrigger - 4 excluding channel selector ToggleSwitch - 4 non-excluding channel selector Gain (mono and stereo) Filters (LP, HP and BP) - 1st, 2nd and 3rd order Two way mono crossover - 1st, 2nd and 3rd order Three way mono crossover - 1st, 2nd and 3rd order - Distortions - mathematical simulations of classic distortion circuits BigMuff DS-1 Muff Fuzz - SopoperLooper LV2 simplified port of the SooperLooper. All plugins from our repository have the HTML MOD GUI included. In our Github repository - www.github.com/portalmod - we also have plugins that were forked from the original repositories. One of our aims is to trigger a dialogue with the developers, deprecate our forks and add the MOD interface to the original plugins but that depends on the developers and creators and shall be discussed in a one-to-one basis. Wish you all the best Kind regards Gianfranco The MOD Team

[ANN] Qtractor 0.6.3 - The Armed Hadron beta release!

by Rui Nuno Capela

Ah, the equinox... Twice a year a cherished planetary alignment checks in on schedule, once again. The little rock gets another round from its warmy solar furnax, from which were forged. The pale blue dot gets yet another round and to no surprise, another tinier dot gets here around: Qtractor 0.6.3 (armed hadron beta) is now released! Release highlights: * Revamped mixer (un)dockable panels (NEW) * Plugin preset selection sub-menu (NEW) * LV2 Time position/transport event support (NEW) * Constrained plugin multi-instantiation (FIX) * Automation curve node resolution (FIX) Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. nb. Despite the old Qt4 stance, but still recommended, Qtractor does build, runs and does it all on Qt5 for quite some time now. However, the former recommendation prevails as the despicable LV2 plugin GUI X11/embedding support through libSUIL just does NOT work on modern Qt5. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sourceforge.net/qtractor/qtractor-0.6.3.tar.gz - source package (openSUSE 13.1): http://download.sourceforge.net/qtractor/qtractor-0.6.3-13.rncbc.suse131.sr… - binary packages (openSUSE 13.1): http://download.sourceforge.net/qtractor/qtractor-0.6.3-13.rncbc.suse131.i5… http://download.sourceforge.net/qtractor/qtractor-0.6.3-13.rncbc.suse131.x8… - quick start guide & user manual (still outdated, see wiki): http://download.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - wiki (help wanted!): http://sourceforge.net/p/qtractor/wiki/ Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Make the mouse-wheel to scroll the plugin list views, when not hovering a direct-access parameter slider. - Mixer widget gets (un)dockable Inputs and Outputs panels, also with their respective title captions. - Plugin instantiation is now constrained as much to prevent any audio channel output overriding. - Existing plugin presets may now be selected right(-click) from plugin list context-menu (ticket by Harry van Haaren, thanks). - So-called "painting" over multiple selected event values, while on the MIDI clip editor view pane below the main piano-roll (eg. note velocities, controller values, etc.) is now split into two similar painting modes, whether the sub-menu Edit/Select Mode/Edit Draw is set on (free-hand) or off (linear). - Drag-and-copy of plug-in instances across tracks or buses (ie. cloning) now also copies the direct access parameter setting (ticket by Holger Marzen, thanks). - File/Save As... now prompts and suggests an incremental backup name for existing sessions files. - Zooming in/out increment is now augmented by whether shift /ctrl keyboard modifiers are set (on a ticket request by Holger Marzen, thanks). - LV2 Time position event messages for plugin atom ports that support it is now being implemented. - Attempt to break extremely long audio file peak generation on session close or program exit (as reported by EternalX, thanks again). - MIDI Controllers Hook and Invert properties are now properly saved for tracks (after bug report by Nicola Pandini, thanks). - A segmentation fault when closing with VST plugins open has been hopefully fixed (after a patch by EternalX, thanks). - Messages standard output capture has been slightly improved as for non-blocking i/o, whenever available. - Automation curve node editing has been slightly improved in regard to time positioning and resolution.
