[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

ZynAddSubFX Usability Survey

by Mark McCurry

Hi there linux audio users, Over the past several years the ZynAddSubFX team has been trying to modernize our versatile synth. It has gained some pretty significant features such as MIDI learn, LV2/VST plugin versions, near full realtime safety, and remote user interface support. One thing which hasn't changed all that much structurally though has been the user interface. As a next major step for the project is a full rewrite of the UI, replacing the current junk-drawer of knobs with a much easier to navigate and explore interface based off of a mockup by Budislav Stepanov [1][2]. This UI will be a single window design, which will be resizable, present more consistent means of interaction, present more interactive views on synthesizer data, and be built with touch interfaces in mind. In order to make this a possibility I'm going to be working full-time on this for a few months and releasing it under an open-source eventually model. As this is a huge project and zyn is relatively well known in the LA community, I'd like to solicit feedback about this interface project and general usability/interface issues that already exist. This feedback is incredibly valuable and it will help greatly in making this next step forward what the larger community wants. Here's a short survey on the topic: http://goo.gl/forms/st8xv3s2I9 For those of you which might be interested in hearing about this project as it progresses, there's an announcement-only mailing list at: http://eepurl.com/bS2Z0P Thanks for taking the time to read this and providing any feedback, --Mark ZynAddSubFX Developer [1] http://zynaddsubfx.sourceforge.net/mockups/mockup-2014.html [2] http://budislavtvp.deviantart.com/art/ZynAddSubFX-UI-UX-Concept-2015-455890…

CMS for self-hosting audio files?

by stephen.doonan＠gmail.com

Does anyone know of or can suggest a CMS (content management system, such as the many MySQL/PHP, Ruby, Python or newer GOlang alternatives that produce dynamic HTML webpages on the fly or static websites) that are focused on self-hosting of audio files at one's own Internet domain? SoundCloud.com, BandCamp.com, ReverbNation.com, PicoSong.com and others are 3rd-party audio file hosting solutions/websites, but some people (such as myself) might prefer to host audio files (podcasts or music, etc.) at their own domain. Thanks and best wishes, Steve

LMMS tune (LAC 2014)

by Louigi Verona

Hey everyone! A couple of years back I made a short tune during LAC 2014 and never released it. While it's not something super special, at the same time I always like to show off how LMMS sounds, even with stock sounds and synths. So here, a short, not properly complete tune: http://www.louigiverona.com/files/cosmos_2.ogg -- Louigi Verona http://www.louigiverona.com/

[ANN] Qtractor 0.7.7 - The Haziest Photon is out!

by Rui Nuno Capela

Hi everybody, On the wrap of the late miniLAC2016(a)c-base.org Berlin (April 8-10) [7][8], where this Yet Same Old Qstuff* (continued) workshop [9] babbling of yours truly (slides, videos[10]) was taken place. There's really one (big) thing to keep in mind, as always: Qtractor [1] is not, never was, meant to be a 'do-it-all' monolith DAW. Quite frankly it isn't a 'pure' modular model either. Maybe we can agree on calling it a 'hybrid' perhaps? And still, all this time, it has been just truthful to its original mission statement--modulo some Qt [2] major version numbers--nb. it started on Qt3 (2005-2007), then Qt4 (2008-2014), it is now Qt5 full throttle. It must have been like start saying uh. this is probably the best dot or rather beta release of them all! Now, Qtractor 0.7.7 (haziest photon) is out! Everybody is here compelled to update. Leave no excuses behind. As for the 'mission statement' coined above, you know it's the same as ever was (and it now goes to eleven years in the making [11]): Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sf.net/qtractor/qtractor-0.7.7.tar.gz - source package: http://download.sf.net/qtractor/qtractor-0.7.7-25.rncbc.suse.src.rpm - binary packages: http://download.sf.net/qtractor/qtractor-0.7.7-25.rncbc.suse.i586.rpm http://download.sf.net/qtractor/qtractor-0.7.7-25.rncbc.suse.x86_84.rpm Git repos: http://git.code.sf.net/p/qtractor/code https://github.com/rncbc/qtractor.git https://gitlab.com/rncbc/qtractor.git https://bitbucket.org/rncbc/qtractor.git Change-log: - LV2 UI Touch feature/interface support added. - MIDI aware plug-ins are now void from multiple or parallel instantiation. - MIDI tracks and buses plug-in chains now honor the number of effective audio channels from the assigned audio output bus; dedicated audio output ports will keep default to the stereo two channels. - Plug-in rescan option has been added to plug-ins selection dialog (yet another suggestion by Frank Neumann, thanks). - Dropped the --enable-qt5 from configure as found redundant given that's the build default anyway (suggestion by Guido Scholz, thanks). - Immediate visual sync has been added to main and MIDI clip editor thumb-views (a request by Frank Neumann, thanks). - Fixed an old MIDI clip editor contents disappearing bug, which manifested when drawing free-hand (ie. Edit/Select Mode/Edit Draw is on) over and behind its start/beginning position (while in the lower view pane).

Fluidsynth: map each channel to individual jack audio output

by Lorenzo Sutton

Hi all, I have also posted this on the fluid-dev list, but maybe there is some wisdom on LAU about it as well :) What is the current status of synth.audio-channels and synth.audio-groups on Linux with jack? By starting fluidsynth with something like: fluidsynth -a jack -o synth.audio-channels=4 -o synth.audio-groups=4 \ -o audio.jack.multi=no I do get 4 pairs of jack audio outputs. However the behaviour isn't as expected at least according to this (very old post): https://lists.nongnu.org/archive/html/fluid-dev/2004-02/msg00027.html Ideally is there a way to have each channel routed to a separate audio output on jack these days? Any help appreciated. Lorenzo
