Hello, I propose to collect in this thread a list of audio programs which could give a great contribute to the linux audio experience, but can't due to halted development, leaving them in a usable or less usable state. This list could then be used for developers in search of some worthy/interesting project to contribute to. I propose two programs who aren't developed anymore: rezound jack-rack I really love them and I feel sorry there's no developer taking care of them. Hope this can be useful Renato

X Window Midi Arp Toy

by james morris

I think this has some potential if it were realized as an application with it's own window space and dedicated widgets rather than as a bash script utilizing xterms and window-manager window-placement. It maps the positions of the popup xterms to note-pitch and note-velocity. I don't know though, it's probably been done already.. I sent it to LAU.. Here's the text describing it further, which probably is a good idea to read quickly: http://jwm-art.net/art/text/xwinmidiarptoy.txt Here's the actual BASH script: http://jwm-art.net/art/text/xwinmidiarptoy james.

Re: [LAD] dead audio projects worth resuming

by humbert.olivier.1＠free.fr

Hi, I made on linuxmao.org a glossary for softwares. You can find the master's page here : http://www.linuxmao.org/tikiwiki/tiki-index.php?page=Glossaire+des+logiciels When I begun this project, it was a single listing-page with all softs that have a dedicaced page on linuxmao.org, but after watch this first list grown and grown and grown, I decided to cut it on : 1) actual (has an update since january 2009) : http://www.linuxmao.org/tikiwiki/tiki-index.php?page=Liste+des+logiciels+li… 2) almost-actual (last update between januray 2005 and january 2009) : http://www.linuxmao.org/tikiwiki/tiki-index.php?page=Liste+des+logiciels+li… 3) museum-section (last update before 2005) : http://www.linuxmao.org/tikiwiki/tiki-index.php?page=La+section+mus%C3%A9e there is too a special page with ladpsa/dssi/lv2 plugins and host/protocol : http://www.linuxmao.org/tikiwiki/tiki-index.php?page=Liste+des+greffons and few others that you can find on these pages. All of this is in french (enjoy ! ;) ) That being said, if at the begining, i was alone on this work, now it's a team work and we made "software versions surveillance" each month, so, it's up-to-date. Bye, and happy to hear something who make me thing that reZound can will be reworked/update :D Olivier, http://www.linuxmao.org

Has anyone ever played a plugin in realtime ... [related to:] hard realtime performance synth

by Emanuel Rumpf

Has anyone ever played a plugin in realtime ( live )... ...and I don't mean a one-finger melody, but a mutli-polyphonic piano piece, eventually with sustain held down, which resulted in about 20 to 40 simultaneusly processed voices. I just realized, that I've never been able to do that. Neither almost. Frustration. But on my digital piano, I can to it. That thing is some years old and definitely doesn't have 2 x 2 GHz processors available. Anyway. The answer so far has been: That system is more dedicated, thus it can, while my PC cannot. The conclusion: I'm working with a wrong system ! - It doesn't allow me to work the way I intend. Damn. What did I buy this system for ? I don't need those 2 x 2GHz for word processing - right ?? This makes me wonder: Which one is the system for my requirements ? Which one is able to make some softsynths / samplers process 30 voices in less than 9 milliseconds ? Could my system be extended or modified in order to suit ? How then ? We have dedicated hardware for graphics, why not for audio ? Sincerely -- E.R.

Re: [LAD] Anyone testing the new TerminatorX release?

by gerald mwangi

Hi, for the timebeing mp3 support is broken is sndfile doesn't actually support it. You'll have to use wav files. What do you mean by "It won't connect to Jack"? You dont see the Terminator outputin qjackctl? Or you cant connect them? Check the prefs if you've enabled Jack as the output.

[ANN] Non DAW and Non Mixer 1.0.0

by malnourite＠gmail.com

I'm pleased to announce the release of Non-DAW and Non-Mixer version 1.0.0. Some version numbers have been skipped, as a lot time as gone without an official release. Those who have followed Non-DAW via git will only notice a few changes, most of them pushed very recently. The chief advancement provided by this release is the long overdue inclusion of the Non-Mixer. This completes the Non triad and should cover the needs of many, some in ways I haven't yet imagined (it covers my needs almost completely). Non-Mixer is a stand-alone modular mixer application for JACK. It hosts several internal modules, one of which hosts LADSPA plugins. All parameters can be controlled through the GUI or externally via Control Voltage signals [the native control sequence output of Non-DAW] (but a MIDI<->CV gateway program exists, for other uses). It has the unique feature of each strip having its own JACK client, which has promising implications for parallel processing. Non Mixer also has a fast, light FLTK GUI, which finds no problem in rendering hundreds of strips. I have plans to add support for DSSI plugins. Currently, Non-DAW and Non-Mixer are kept in the same repository, even though they are entirely independent applications. I have already begun to restructure the repository and build system and I plan to split the repositories for the two projects out completely, as time allows. This release is dedicated to Deanna, whose untimely demise, in addition to the rumors of my own death, has reminded me of my mortality and the necessity of realizing my dreams while I still have the opportunity. I will not be discouraged, so don't bother trying. I will resist blind adherence to the status quo, as I always have--but now even more fiercely. Progress will not happen on its own. It must be forced along by individuals of power, wisdom, and vision; which we should all aspire to become. But I digress. Non-DAW and Non-Mixer (and Non-Sequencer) can be acquired via git from the URLs listed on the Non website: http://non.tuxfamily.org A shortlog from v0.5.0 to v1.0.0 follows: Jonathan Moore Liles (224): Remove dependence on FLTK >= 1.1.8. Make mute and solo buttons more colorful. Fix offset error in selection rectangle. Don't lose track of timeline focus when window loses focus. Provide a keybinding/menu entry for track renaming. Add action to set range from region position and length. Handle very long port names. Make normalization work properly with looped regions. Improve the appearance of rec/mute/solo buttons.

User can temporarily disable snapping by holding down 's'. Make it optional (Options/Behavior/...) wether or not stopping the transport disables global record.

setting a runlevel at the boot prompt?

by Jörn Nettingsmeier

hi everyone! here's a question for sysadmin type low-latency adepts: i have a general-purpose notebook that doubles as a lean and mean recording machine. it's opensuse, which means it works nicely with most bells and whistles, but it also has an awful lot of questionable stuff running that interferes with stable low-latency performance. so i usually boot into a ll kernel and kill everything i don't need for the duration of a session. to ease that job, i have put the (unused) runlevel 4 back to work: basically i copied rc5.d into rc4.d and ruthlessly deleted everything i don't want. now "sudo telinit 4" will slim down my process list. since the runlevel corresponds with the need for a ll kernel, i wonder: is there any way to tell the kernel (via grub) to tell init to ignore the initdefault in /etc/inittab and go directly to runlevel $FOO? and while we're there, doing a kexec instead of a warm reboot would be so sexy - has anyone played with that yet? tia, jörn

linuxsampler plugin ?

by Dave Phillips

Greetings, I'm testing the Linuxsampler plugin with Ardour3 SVN. The plugin loads correctly, and when I launch the Fantasia GUI it identifies itself correctly in the interface. I can load a MIDI file in A3 and watch it play the keyboard on the LS plugin. Everything looks good, but there's no sound. There's also no instance of Linuxsampler in QJackCtl. When I run LS + Fantasia standalone I noticed that it doesn't autoconnect to JACK. Perhaps this is the problem, but I can't find where to configure LS to autoconnect. Any suggestions ? This is a low-priority issue for me, but it'd be nice to figure out what's happening. Best, dp
