[ANN] Vee One Suite 0.8.5 - An Autumn'17 release

by Rui Nuno Capela

Howdy! 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 released for the seasonal greetings. All still available 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]. The common change-log for this Fall goes like this: - Sample files are now saved as symlinks when saving to JACK and/or NSM session directories/folders (applies to samplv1 [2] and drumkv1 [3] only). - Opening multiple preset files is now possible, populating the preset drop-down listing, while only the first one is loaded effectively into the scene as usual. - Mono(phonic) "Legato" mode option introduced. - Desktop entry specification file is now finally independent from all build/configure template chains, whatever. - Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData). And now, in reverse order of appearance: **padthv1 - an old-school polyphonic additive synthesizer [4]** padthv1 0.8.5 (autumn'17) released! padthv1 is an old-school polyphonic additive synthesizer with stereo fx padthv1 is based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis.

"Sonoj", a community organized event about Open Source Music Production struggles to get funded. Please help

by Nils, Sonoj Convention

(Disclaimer: I am an organizer of this event) In less than a month the "Sonoj Convention" shall happen. [quote]Admission is free. You will be able to enjoy demonstrations, talks and workshops about music production through open source software. Hands-on tutorials and workflow presentations can be expected. Everything will be recorded and released as online videos afterwards. [/quote] Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. For that we are asking for some modest donations here: https://www.startnext.com/en/sonoj Currently it looks like that this will not succeed, as you can see from the link above. This is the usual "all or nothing" platform that only gives you money if the goal is reached, otherwise donors get their money back. However, despite submitting the event announcements and several updates to nearly one hundred on-topic websites, magazines (including posting it ourselves on KVR, Reddit etc.) and blogs there is nearly zero response. That excludes the Linux Audio Scene itself, which was very supportive to this day (at least the news, not the donations). I was hoping that Sonoj could be an event that brings in people from the "outside", that are not already well connected with Linux Audio. It seems I was wrong. So here I am in one of the last places I wanted to ask for donations, because this is the crowd that usually already gives a lot, be it their own time, development of software or actual donations to well deserving projects. Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. https://www.startnext.com/en/sonoj Yours Nils, for the Sonoj Convention https://www.sonoj.org

Jitter analysis

by benravin

Hi, I'm facing a timing jitter which happens periodically due to some interrupt, which is causing the task to be delayed. Since this happens periodically, it is indeed a slow varying timing jitter, for example every 400ms, the timing deviation is in the order of few ms ( 4-6ms). This is not getting filtered out by DLL, and results in a slow varying oscillations which never dies. Any way to identify and limit these timing jitters and not to take any action on drift correction by DLL ? -ben -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-dev-f58952.html

GNU Guitar 0.4.0-alpha released

by Taylor

GNU Guitar is a guitar effects processor, much like Guitarix and Rakarrack. It was started about ten years ago, formally known as GNUitar. Over the last year, it has been refactored (and some parts completely rewritten) to use modern software technologies. It's cross-platform, so it runs on Linux systems and Windows (macOS is on the to-do list). Here's a link to the change summary: https://github.com/gnu-guitar/gnu-guitar/releases/tag/v0.4.0-alpha The project is in it's infancy still. Let me know if you're interested in contributing!

[LAA] [LAU] Guitarix 0.36.0 released

by Hermann Meyer

Guitarix release 0.36.0 Guitarix is a tube amplifier simulation for jack (Linux), with an additional mono and a stereo effect rack. Guitarix includes a large list of LV2 and LADSPA plugins, and support LADSPA / LV2 plugs as well in it's racks. The guitarix engine is designed for LIVE usage, and feature ultra fast, glitch and click free preset switching and is full Midi and remote controllable (the Web UI is not included in the distributed tar ball). This release add a couple of features to the lately introduced DrumSequencer plugin. It add 2 more toms, it add beat repeat/skip switches, it add the possibility to add a sequence (Preset) to the current one, switch to previous/next preset, . . or load a slected preset (sequence) all controllable with Midi CC. Also it introduce new Midi Note ON to CC support, means, you could control toggle switches with Midi Note On messages now (continues control). Also it introduce a new option to load Stereo plugs as Mono plugs, eg. before the amp. This is in special useful for the famous rkrlv2 plugs: https://github.com/ssj71/rkrlv2 + new configure options --fontdir (set font install directory) and --no-font-cache-update (dont automatically update the font cache) + fix build with --no-lv2-gui option + add new style "Gold" + fix GxAmplifier re-init convolver on buffersize change ( Ardour loops) + fix jack transport support + also fix midi clock and bpm sync support + fix load online preset in remote UI + fix trim label in Lv2/Ladspa plugins beside that a couple of changes have been made under the hut. Refer to our project page for more information: http://guitarix.org Download Site: http://sourceforge.net/projects/guitarix/ Forum: https://guitarix.sourceforge.io/forum/ Consider visiting our forum or leaving a message on guitarix-developer(a)lists.sourceforge.net enjoy and keep on rooking. regards hermann

spectmorph-0.3.4

by Stefan Westerfeld

spectmorph-0.3.4 has been released. Overview of Changes in spectmorph-0.3.4: ---------------------------------------- * Added optional ADSR Envelope * Make LV2 and VST plugin stereo to allow supporting stereo in the future * LV2 plugin description fixes * Added about dialog to plugin/smjack UI * Remove BEAST plugin (plugin code will be moved to BEAST) * Fixed compilation for newer g++ >= 6 (std::fabs) * Get rid of some malloc() calls in linear morphing What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work ------------------------------------- In order to make music that contains SpectMorph, you currently need to use Linux. There are four ways of integrating SpectMorph sounds into music you create: - LV2 Plugin, for any sequencer that supports it. - VST Plugin, especially for proprietary solutions that don't support LV2. - JACK Client. - BEAST Module, integrating into BEASTs modular environment. Note that at this point, we may still change the way sound synthesis works, so newer versions of SpectMorph may sound (slightly) different than the current version. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads/spectmorph-0.3.4.tar.bz2 There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

[ANN] Qtractor 0.8.4 - End of Summer'17 release!

by Rui Nuno Capela

Yes, it's been like clockwork... Every two months or so, you stumbled with a brand new dot release, code-named after some of the same adjective-plus-noun (or vice versa) code-names. You knew the thrill and yet it lands no more. First, the code-naming joke has been just a parody--or was it the other way around?--to some well known Linux-distro 'alimalistic' code-name series. Then on it got rogue into some directed puns--remember the date when BitWig Studio 1.0 was first released? Yeah, the "Byte Bald" was there for the pun, on the very same day :) Well, that's all gone by now. Northern hemisphere seasons are the new norm and that's about two main reasons: first, it's where I live; second, due to an undeniable global warming effect pervading the globe, all geographical temperate zones are simply on the edge of extinction. More or less in a couple of decades or so. For the sake of brevity, I will just leave it like paying homage to those natural concepts that are facing an inexorable fate. And yet, there're still the good news: Qtractor 0.8.4 (end of summer'17) released! Change-log: - Assigned MIDI Controllers to plug-in's Activate switch are now finally saved and (re)loaded properly across sessions. - Audio clip panning option property is now being introduced. - Out-of-process (aka. dummy) VST plug-in inventory scanning now restarts automatically and resumes processing in case of a premature exit/crash; VST plug-in inventory scan/cache persistency is now in place. - Desktop entry specification file is now finally independent from build/configure template chains. - Updated target path for freedesktop.org's AppStream metainfo file (formerly AppData). - Changing the View/Options.../Display/Custom/Style theme takes effect immediately unless it's back to "(default)". - Slightly slower but better approximation to IEEE 32bit floating point cubic root ie. cbrtf(). 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.

Fedora 25 x86_64; Pulseaudio removed; ALSA recording and playing from multiple sources - JACK?

by Philip Rhoades

People, For playing from multiple sources, ALSA plus the version of .asoundrc below has been rock-solid for a couple of years now: I now want to use things like "recordmydesktop" which work fine with the mic but they do not record sound from audio or video clips that are playing eg from YouTube or local mpv etc. So, yet again, I started to try and make sense of JACK because I was pretty sure that it could solve this problem - but I have found sound on linux has always been a major pain and messing around with configs and rebooting etc on my big workstation is tedious so I think I will try to get something working on my laptop to begin with. Hopefully some jack gurus will have some suggestions about how to do what I want to do? I presume it is possible? Thanks, Phil. pcm.!default { type plug slave.pcm "asymed" } # This is the audio output: pcm.dmixer { type dmix ipc_key 1024 slave { pcm "hw:1,0" period_time 0 period_size 1024 buffer_size 4096 rate 44100 } bindings { 0 0 1 1 } } ctl.dmixer { type hw card 0 } # This is the microphone pcm.dsnooped { ipc_key 1027 type dsnoop slave.pcm "hw:1,0" } # This makes both channels work together. pcm.asymed { type asym playback.pcm "dmixer" capture.pcm "dsnooped" } -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au
