[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

[LAU] NAMA, non-distructive?

by Hart Larry

Thank you MR Hawaii, I forgot I had installed that, but looking in its man-page, makes references to non-distructive editing. If I understand the concept, I would think editing out portions of sound would certainly be destroying an orriginal. Meanwhil, if I run nana -t and a file name, I get the following error: Found config file: /home/chime/.namarc YAML::Tiny found bad indenting in line ' consumer:' at /usr/share/perl5/Audio/Nama/Assign.pm line 283. So please, how do I fix this-and-would NAMA be an interactive editor? Thanks in advance Hart

[LAU] Alternative FluidSynth GUI?

by Dan Capp

Research tells me that QSynth seems to be the only currently available/usable GUI for FluidSynth, but I get big xruns whenever I try and use it. FluidSynth itself doesn't cause me problems (I know because I'm able to use the FluidSynth-DSSI plugin fine in Rosegarden etc). The problem is that I want to use FluidSynth with Ardour3, but Ardour3 doesn't support DSSI plugins yet. So the only solution I have is to find a standalone interface for FluidSynth and then to link up using Jack. I looked at the old GUI 'FluidGUI' but it seems to be so old that it won't properly install on recent versions of Ubuntu. So does anyone know of: 1) A GUI for FluidSynth other than QSynth and FluidGUI?... or 2) An application other than the above 2 which would allow me to load soundfonts? Thanks in advance. - Dan

[LAU] irqbalance

by Brent Busby

On Debian/Ubuntu systems, the irqbalance package which tries to push interrupts across all your CPU's fairly, has been part of the base system for a long time. On Gentoo, it's an available package, but not installed by default. Is irqbalance recommended for RT audio? Deprecated? Doesn't matter?

[LAU] Praxis LIVE v2.2.0

by Neil C Smith

Hi All, Praxis LIVE v2.2.0 is now available for download from www.praxislive.org This is the first release to upgrade the OpenGL renderer to Processing v3. Feedback on whether this is working well would be appreciated. Full change log - * OpenGL video pipeline updated to Processing v3.0.1 / JOGL v2.3.2. While providing major performance and stability improvements, this is a major change and there is the possibility for some regressions. Please update carefully and report any issues. * Optional support for GStreamer 1.x. This can be set under Tools / Options / Video / GStreamer (requires restart). Unlike GStreamer 0.10 support, this requires a system installed version of the GStreamer library on all platforms. Windows and OSX users who want to experiment with this feature can download GStreamer from http://gstreamer.freedesktop.org/download/ * New core:tracker component, and simple table-based tracker editor (use popup menu and Edit patterns to access). More advanced editing features to follow. * New routing components - core:routing:every for allowing through every n-th message, and core:routing:order to prioritise dispatching of messages. * New audio:clock component for more stable timing in BPM (quantized to internal processing buffer size). * Internal (and outdated) help removed and replaced with link through to online manual at http://praxis-live.readthedocs.org * TinkerForge bindings updated to v2.1.5. * Added ready and error ports to video:capture and video:player. Can be connected to play or pause to auto-start playback when new file or pipeline loaded. * Many minor bug fixes (see commit log).

by jonetsu＠teksavvy.com

Hello, Basically the subject line says it all. It is the demo version. The X86_64 ran well, stuff was seemingly installed, and then what ? Restarted Ardour 4.4, the FC-70 limiter does not show up in the available plugins. Thanks.

[LAU] [ANN] QjackCtl 0.4.1 is out!

by Rui Nuno Capela

Yup, that's true: QjackCtl 0.4.1 (fall'15) is out! QjackCtl [1] is a(n ageing but still) simple Qt [3] application to control the JACK [2] sound server, for the Linux Audio [4] infrastructure. Website: http://qjackctl.sourceforge.net Downloads: http://sourceforge.net/projects/qjackctl/files - source tarball: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1.tar.gz - source package: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.sr… - binary packages: http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.i5… http://download.sourceforge.net/qjackctl/qjackctl-0.4.1-24.rncbc.suse132.x8… Change-log: - Probing portaudio audio device in a separate thread (by Kjetil Matheussen, thanks). - Messages standard output capture has been improved again, now in both ways a non-blocking pipe may get. - Regression fix for invalid system-tray icon dimensions reported by some desktop environment frameworks. - New hi-res application icon (by Uttrup Renzel, Max Christian Pohle, thanks). - System tray icon red background now blinks when a XRUN occurs. - Desktop environment session shutdown/logout management has been also adapted to Qt5 framework. - Single/unique application instance control adapted to Qt5/X11. - Prefer Qt5 over Qt4 by default with configure script. - Override-able tool-tips with latency info (re. Connections JACK client/ports: patch by Xavier Mendez, thanks). - Complete rewrite of Qt4 vs. Qt5 configure builds. - French (fr) translation update (by Olivier Humbert, thanks). License: QjackCtl [1] is free, open-source Linux Audio [4] software, distributed under the terms of the GNU General Public License (GPL [5]) version 2 or later. From the footnote department: for quite some time there's an alternate github.com repository [6] which is kept in sync with the sf.net one [7]. However, this doesn't mean that the QjackCtl project is about to migrate to a brand new hosting whatsoever: the original upstream source code repository is, will be, as ever was, always kept somewhere else still in this world and universe.

[LAU] Did you know that...

by Dave Phillips

There is a VST plugin that runs Pure Data patches http://pd-pulp.net/ The Oxe FM synth is now available as a native Linux VST https://github.com/oxesoft/oxefmsynth There is a Renoise tool that provides an interface for the processors from the Composers Desktop Project. http://forum.renoise.com/index.php/topic/41882-new-tool-30-cdp-lua-tool/ Nick Dowell's amSynth now works as a native Linux VST http://amsynth.github.io/ RtCmix has the beginnings of an IDE useful for Linux users https://github.com/jwmatthys/cmixide Commercial interest is higher than ever, with samplers from Renoise (Redux) and discoDSP (Bliss), synths from u-he, discoDSP (Vertigo), and Tracktion (MicroSynths). Bitwig continues its climb towards a 1.2 release, the betas finally have JACK transport control and support for loading FXP/FXB presets into synths such as Obxd and Extent Of The Jam's DigitsVST. Lots of movement on the DAW front, with updated offerings from Renoise, Mixbus, and Tracktion. Good times for Linux-based musicians. Best, dp

[LAU] Migrating from Garage Band to Free Software: Choices?

by worik

This is slightly OT as Free Software on Windows will do just as well.... My colleague with whom I make a lot of music has been squeezing her creativity through a "free" version of Garage Band on a iPad. She has had a great time with the UI but is beset by all the problems we all know of with such products. She does not own, and cannot afford, a Apple computer so cannot really get the benefits of Garage Band. In the Free Software world what would be the best next step? Is there one? I am flumoxed because I have a different approach (I prefers issuing instructions to moving icons) and Garage Band is a complete mystery to me. cheers Worik -- Why is the legal status of chardonnay different to that of cannabis? root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand) I voted for love
