[LAD] Xmomk.lv2 initial release

by Hermann Meyer

I like to announce the initial release for Xmonk.lv2 version 0.1 Xmonk is a sound generator based on the Faust `SFFormantModelBP` from physmodels.lib by Mike Olsen. It's a monophonic formant/vocal synthesizer. The source is a sawtooth wave and the "filter" is a bank of resonant bandpass filters. Xmonk provide a interface to drive the filter/synthesizer via mouse movement. Additional Xmonk provide a midi in port to drive it with any midi controller. On top Xmonk provide a virtual keyboard to drive it with your PC keyboard/mouse combination. Surely you could use your DAW automation to drive it the way you want. Xmonk could play in two different modes, on is the usual note on/off, the other is sustain, means the last note play forever, while you play with the vowel filter settings. Xmonk could be used with a free scaled temperament, or as selected with Equal Tempered scales from 12 to 53. Here you get it: https://github.com/brummer10/Xmonk.lv2 So, have some fun with it, hemrann

[LAD] Work on linuxaudio.org this weekend

by Jeremy Jongepier

Dear all, This weekend the linuxaudio.org VM's will have to be moved to a different cloud region which could lead to some downtime of services provided by linuxaudio.org (i.e. mail and web sites). We'll try to keep impact as low as possible and are aiming at a seamless migration. This migration is necessary because the cloud region linuxaudio.org now lives in is being phased out. We'll keep you posted about the progress. Best regards, Jeremy

[LAD] [ANN] Qtractor 0.9.11 - The Mauerfall'30 Release

by Rui Nuno Capela

Hallo! Not making history or a revolution but as peaceful as thirty years ago ;) Qtractor 0.9.11 (mauerfall'30) is out! And the change-log goes as follows: - Transport/Backward commands now honoring edit-tail, loop-end and punch-out points, when playback is not rolling. - A session name (sub-)directory is now suggested on every new session properties dialog. - Avoid adding any extraneous clip replica when Ctrl+dragging on either of its edges. - When using autotools and ./configure --with-qt=..., it is also necessary to adjust the PKG_CONFIG_PATH environment variable (after a merge request by plcl aka. Pedro López-Cabanillas, while on qmidinet [8], thanks). - Fixing a potential crash-effect in switching MIDI output buses on tracks that are set to show audio output monitoring meters, is on going still. Description: 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.

[LAD] Faster boot on Raspberry Pi 4

by Will Godfrey

I'm using rasbian-buster-lite and once up and running the performance is seriously impressive. However it's dog-slow to start up. The last message I see before the greatest delay (about 30 seconds) is: Raspberry Pi service to switch to ondemand cpu governor (unless shift key is pressed) during boot up. I suspect the *actual* delay is connected with networking, but with systemD I'm totally lost as to where everything is, so any help would be greatly appreciated. On the Pi 3 I'm able to get a devuan image, and that's a doddle to sort out, but there isn't an image for the Pi 4 :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[LAD] [ANN] Vee One Suite 0.9.11 - A Halloween'19 Release

by Rui Nuno Capela

Horror! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here and now released for the global Halloween evening, and all making up to this mythical version 0.9.11 ;) As always, all provided in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Changes for this creepy release are quite revolutionary;) - When using autotools and ./configure --with-qt=..., it is also necessary to adjust the PKG_CONFIG_PATH environment variable (after a merge request by plcl aka. Pedro López-Cabanillas, while on qmidinet, thanks). - Upstream packaging is now split to JACK standalone and LV2 plugin only: the former shared common core and UI package is now duplicated but statically linked though. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.11 (halloween'19) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

[LAD] 100% Open Source Music

by Louigi Verona

Hey everyone! My music "career" started with mod music. Nope, not the music and fashion subculture from the late 1950s, but this mod music <https://en.wikipedia.org/wiki/Module_file>, when people used programs called "trackers" to produce stuff. It was either this or buying expensive hardware. Although people associate MOD music scene mostly with chiptunes, it was much more than that, and has its own pantheon of musical gods <https://modarchive.org/index.php?request=view_chart&query=topartists> who produced tracks ranging from synth pop <https://modarchive.org/index.php?request=view_by_moduleid&query=35280> to jazz <https://modarchive.org/index.php?request=view_by_moduleid&query=135135>, from orchestral <https://modarchive.org/index.php?request=view_by_moduleid&query=120901> to realistic folk instrumentals <https://modarchive.org/index.php?request=view_by_moduleid&query=155605>. Immersed in this music, I severed my link to the mainstream idea of songs with their standard verse/chorus, and endless drivel about relationships. That link has not been restored. My mind was opened to music that was so unlike anything I'd heard before that it felt a bit like walking through that door in the wall. (Is this H.G. Wells reference <https://www.encyclopedia.com/education/news-wires-white-papers-and-books/do…> too obscure? :) ) My heroes were Elwood, DRAX, Awesome. Who even knows these names? I once created a Wikipedia page for Elwood and it stayed up for many years, but recently I discovered that it was removed. And yet Elwood <https://modarchive.org/index.php?request=view_artist_modules&query=69004> is a legendary musician and producer in the MOD scene, who has inspired and awed several generations of fellow tracker musicians. Some names have gotten enough traction to stay on Wikipedia. Purple Motion <https://en.wikipedia.org/wiki/Jonne_Valtonen> is one clear example. Several producers, famous today, started out using trackers. Here is an incomplete list <https://en.wikipedia.org/wiki/Category:Tracker_musicians>. It mostly lacks artists who made their names in the tracking scene, but did not become notable outside of it. It's been a while since I went on a nostalgia tour, but due to my recent project of putting out an album of old tunes called "Only Slightly Embarrassing" <https://louigiverona.com/?page=projects&s=music&t=slightly_embarrassing>, I decided to cross further into the continent of "back in my days", which brought me straight to ModArchive <https://modarchive.org/>. Eventually, I was convinced that I should try making more tracked works, at the very least because my early works were so shitty that I felt I had to make up for that. Long story short, I realized that MOD music is the true Open Source Music. I mean, think about it. The most widely used software today is GPLed ( OpenMPT <https://openmpt.org/>). The modules you release are open source too, just like JavaScript. You open your XM or IT file and inspect how the tune was created. And you learn. And there is surely stuff to learn. Not all of it is even tracker-specific. People had no EQs, no compressors, no reverbs. And yet so much of tracked music sounds just incredible <https://modarchive.org/index.php?request=view_by_moduleid&query=134387>. How did they do it? It turns out, there are ways. Of course, all of that leads to a bit of self promotion. I would like to draw your attention to the two tunes that I've written in the past month with OpenMPT and which you can download and see how they were made. (Or don't. You can instead explore ModArchive's Top Favorites <https://modarchive.org/index.php?request=view_top_favourites>.) - Lid <https://modarchive.org/index.php?request=view_by_moduleid&query=186854> - Twizzy II <https://modarchive.org/index.php?request=view_by_moduleid&query=186855> You can just use an Online Player to listen to them in a browser, or you can use almost any modern player to play them. Audacious, VLC, for example. An interesting thing is that the MOD scene has its own cultural backdrop: it is primarily melodic oriented, and having melodies means a lot. If you don't like melodies, you go for trance. I am putting out minimal house, rominimal even. So, I am sure I will get little love. But for those of you who enjoy this style of music, I think you might like these. I am personally very happy with the sound and how both of these turned out. And yet - no EQing, no nothing. Just volume envelopes, volume levels and panning work. **a little proud** It's somehow interesting to me that this is open source minimal house music. Not a lot of those out there. p.s.: fuck my tracks, listen to this <https://modarchive.org/index.php?request=view_by_moduleid&query=34427> Louigi Verona https://louigiverona.com/

[LAD] DrumGizmo 0.9.18 released

by Bent Bisballe Nyeng

DrumGizmo 0.9.18 Released! DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that has been recorded with a multimic setup. This release is primarily a bugfix release but a few new features also managed to sneak in. Highlights: * Sample selection algorithm now behaves a lot better when using a small sample set. * Error reporting has been drastically improved when loading drum-kits. * Sample normalization option has been added. As usual read the detailed description of all the new shiny features, including some audio samples [1]. And now, without further ado, go grab 0.9.18!!!

[LAD] It's the final (Sonoj) countdown! - live feed with chat - donations

by Sonoj Convention

The end is near! Fortunately only the end of our preparations. Only four days left until this year's Sonoj Convention. For the spontaneous among you there is still an opportunity to sign up and visit. Just enter your name on https://sonoj.org/register.html . Considering the many mails you've received so far, it can be assumed that you're currently in Antarctica and therefore can't actually participate. Therefore now for the last time (this year): Please help us finance our non-profit event by donating an amount of your choice. We accept bank transfers and PayPal: https://sonoj.org/donate.html And finally I would be happy to see you during the two days in our video stream. There will be a chat this year (it already exists), so you can ask questions and comment. The stream is on the Sonoj page, or here: https://streaming.media.ccc.de/sonoj2019 Best regards, Nils Sonoj Convention
