http://quitte.de/dsp/caps.html The latest release of the caps audio plugin suite contains a number of bug fixes and improvements as well as changes intended to make it more suitable for low-power systems. http://quitte.de/dsp/caps.html#CHANGES Most notably, support for a variety of little-used features has been dropped, reducing the binary size by roughly a third. There's also a new plugin implementing simplistic linear emulation of several guitar amplifier loudspeaker cabinets with reduced computational complexity: http://quitte.de/dsp/caps.html#CabinetIII The compressor plugins now report current gain reduction: http://quitte.de/dsp/caps.html#Compress http://quitte.de/dsp/caps_0.9.24.tar.bz2 Cheers, Tim

[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.

jalv.select release v0.9

by Hermann Meyer

jalv.select is a little gtkmm GUI to select lv2 plugs from a list and run them with jalv.

"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!

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.
