[LAD] [ANN] Boss DS-1 simulator LV2 plugin

by Gianfranco Ceccolini

Greetings Linux audio users and developers We are very happy to announce the DS-1 distortion stomp box simulator. You can download it at https://github.com/portalmod/mod-distortion To install use "make & make install" and you'll have the bundle in /usr/local/lib/lv2 folder. It uses a mathematical model of the original DS-1 electrical circuit and the programmer (André Coutinho) took lots of care to stick to the analog circuit setup. More simulators are on the way, hence the mod-distortions repo. Feedbacks are always welcome. Happy 2014 for everyone Gianfranco The MOD Team

[LAD] JACK, cgroups and systemd

by Dominique Michel

Recently, I experimented with Debian sid, which use systemd. Systemd idea is nice, but its implementation is a catastrophe. It is more than one year I am using the kernel cgroups on gentoo to get rt scheduling with JACK, that without any trouble. On Debian, this is just impossible, because whatever I try, systemd insist to put what it think is good to have into the rt cgroup, which soon or later result in a complete system freeze with even dead magic keys. After loosing my time a few days with this, I removed Debian and installed gentoo instead. I found the reason here: http://article.gmane.org/gmane.linux.kernel/1063354 "Lennart Poettering: Well, this feature is... completely irrelevant for normal desktop people. ... In fact, I just prepped a patch to systemd to move every service and every user session into its own cgroup in the 'cpu' hierarchy (in addition to the group it already creates in the 'systemd' hierarchy)." Another completely idiotic stuff of this guy. The point of the cgroups is it is possible to setup them for whatever use will be made with a computer, and this guy think he have the insane and pretentious capability to decide for every single user of the use they will made with their computers, and he is suggesting users doing something else are abnormal. He must be stopped! Regards, Dominique

[LAD] Static verification of real-time safety

by David Robillard

Hello, Does anyone know if anything has emerged from http://www.google-melange.com/gsoc/proposal/review/google/gsoc2012/fundamen… or, what alternative solutions for doing the same thing exist today? I know I have #ifdef __clang__ # define REALTIME __attribute__((annotate("realtime"))) #else # define REALTIME #endif in my code and was tinkering with an implementation capable of doing this at some point, but can't dig up the details, or whatever system I was using to do it. It would be oh so very nice to be able to statically verify that code is real-time safe... -- dr

[LAD] deteriorate-lv2 1.0.2 released

by Aurélien Leblond

Hello all, Yesterday I released the version 1.0.2 of deteriorate-lv2. This set contains a very simple and basic granular effect and a simple/basic downsampler. I kept the code very simple and basic on purpose. They might not be the most refined plugins around, but they create a nice sound nonetheless... More info here: http://objectivewave.wordpress.com/deteriorate-lv2/ A demo video can be found here: http://www.youtube.com/watch?v=C63m5FdlzX0 Enjoy! Aurélien

[LAD] beatslash-lv2 1.0.2

by Aurélien Leblond

>> To celebrate this release, I made a video demonstration of what it can do: >> http://www.youtube.com/watch?v=RtZkKfTJEK8 > > Quite interesting. I'm not sure if I really understand what's going on > in the video. Esp. for what Seq24 is used. Thanks. All right so :) - Hydrogen output goes into Ingen input - Ingen has the repeater and slicer one after the other, and the output of that is recorded So in a nutshell, Hydrogen goes to Repeater which goes to Slicer which goes to Output. Seq24 is there to trigger the repeater or the slicer using the trigger module of Ingen. I used Seq24 here to be perfectly in sync... I tried to do with manually with a midi keyboard but unfortunately wasn't precise enough :) Hope that's clearer. Otherwise don't hesitate to ask :) Aurélien

[LAD] [LAU][ANN][MOD] mod-host supports MIDI controllers

by Ricardo Crudo

Hello LAD, LAU. I've pushed a new branch of the mod-host<https://github.com/portalmod/mod-host>(midi-control), the code in this branch makes possible assign MIDI controllers to control any input parameter of the lv2 plugins. This is in development yet, but anyway I'm inviting you to try it as is and, if possible, help us reporting bugs or suggestions of improvements. Two new commands were added: map and unmap. The sintaxes are: map <effect_instance> <parameter_symbol> unmap <effect_instance> <parameter_symbol> After run the map command, just acts in the control that you wanna assign to (MIDI Learn). The feedback to user is very poor yet, so you won't receive a message saying if the mapping was well done. I hope you enjoy it. Regards, Crudo

[LAD] Calling all developers

by Gabbe Nord

Hey everyone! In an effort to eventually bridge the gap between users and developers, and specifically explore the contributions users that aren't programmers can make to free and open source software, I have designed a short survey for active developers. More information and the survey itself is available on http://www.zthmusic.com/developer-survey/. I'd greatly appreciate any participation from developers. As mentioned on the page, I will compile the results of this survey into an infographic. I will also eventually publish all of the results freely to anyone, so everyone can have a look at the data. I hope this survey can give some good data, that can spark some good discussion on how we can further integrate users and developers, and make more use of the great community we have! Cheers and merry christmas everyone, Gabriel/zth
