OpenAV Releases Jan 2021

by Harry van Haaren

Hey Linux Audio *, After some time away, OpenAV is back with some updated releases! Much of the work done in these releases was in collaboration with the Linux Audio Developers and Uesrs community, thanks for your contributions! This release announce email includes ArtyFX 1.3.1, a dot release with various bugs fixed and general cleanups. A future 1.4 release will include more dramatic changes, including addressing some open issues. Find 1.3.1 here: https://github.com/openAVproductions/openAV-ArtyFX/releases/tag/release-1.3… But that's not all, Ctlra library for accessing USB hardware from music software also gets a release! Its a 0.1, there's still lots of work to do, but there's also progress being made, so doing some releases to show the actual progress is a good idea. This release contains Kontrol S5 support (including screens! :) and a bunch of simplifications, reduced dependencies in the examples, cleanups, optimizations and more! Find v0.1 here: https://github.com/openAVproductions/openAV-Ctlra/releases/tag/release-v0.1 With that, thanks for reading, and hope to chat to yee all on #lad on irc.freenode.net soon! Regards, -Harry from OpenAV -- http://www.openavproductions.com

Kickmess 0.2.1 - First official release

by Weird Constructor

Hi! I finally released my first (VST) plugin synthesizer. Kickmess is a kick drum synthesizer. It is a port of the easy to use and good sounding Kicker plugin from LMMS to a reusable audio plugin format on Linux (VST currently). The DSP code has been ported and also changed, that means an accurate reimplementation of Kicker is out of scope. Features: * Sine oscillator * Noise oscillator * Pitch and amplitude envelopes with configurable exponential slope * Pitch from MIDI note * Simple Distortion effect You find the Rust sources and binaries for Linux and Windows on GitHub: * Project website: https://github.com/WeirdConstructor/Kickmess * Release: https://github.com/WeirdConstructor/Kickmess/releases/tag/v0.2.1 More features and changes might be added and before Version 1.0 is released. I can't guarantee that your presets will sound the same. After Version 1.0 significant changes will come with a change in the major version number. It's not just a port from LMMS to VST, but also a port from C++ to Rust. Writing DSP code in Rust is really nice and straightforward. Most work was developing the GUI, as it required lots of experimentation, testing and debugging in the graphics and window libraries. But Rust is finally there and the boring plumbing and GUI work on this plugin is finished. Greetings and have a nice day! Weird Constructor

New Session Manager Version 1.5.0

by software＠linuxaudio.org

Linuxaudio.org presents: New Session Manager Version 1.5.0 ## Summary WARNING! Next scheduled release (2021-04-15) will switch the default session root to $XDG_DATA_HOME ( default on most distributions: ~/.local/share/nsm/ ) With Aprils release please prepare to do one of the following: * Move old sessions to the new root directory (preferred) * Symlink "~/NSM Sessions" to the new root directory * use the nsmd --session-root commandline argument. All changes are made only on the server side, or in the tools we provide. Existing sessions, clients, and GUIs remain 100% compatible without requiring any changes. Please see the CHANGELOG highlight below. The project can be found on Github: https://github.com/linuxaudio/new-session-manager/ https://github.com/linuxaudio/new-session-manager/releases/tag/v1.5.0 API Document: https://linuxaudio.github.io/new-session-manager/api/index.html ## Full Release Announcement: New Session Manager (NSM) is a tool to assist music production by grouping standalone programs into sessions. Your workflow becomes easy to manage, robust and fast by leveraging the full potential of cooperative applications. NSM is free in every sense of the word: free of cost, free to share and use, free of spyware or ads, free-and-open-source. You can create a session, or project, add programs to it and then use commands to save, start/stop, hide/show all programs at once, or individually. At a later date you can then re-open the session and continue where you left off. All files belonging to the session will be saved in the same directory. Check your distributions in a few days for New-Session-Manager 1.5.0 You can find the source release on Github: https://github.com/linuxaudio/new-session-manager/releases/tag/v1.5.0 Bullet Points * Drop-In replacement for the non-session-manager daemon nsmd and tools (e.g. jackpatch) * Simple and hassle-free build system to make packaging easy * Possibility to react to sensible bug fixes that would not have been integrated into original nsmd * Stay upwards and downwards compatible with original nsmd * Conservative and hesitant in regards to new features and behaviour-changes, but possible in principle * Keep the session-manager separate from the other NON* tools Mixer, Sequencer and Timeline. * Protect nsmd from vanishing from the internet one day. * The goal is to become the de-facto standard music session manager for Linux distributions # Changes since new-session-manager v1.4.0 (2020-08-14) All changes are made only on the server side, or in the tools we provide. Existing sessions, clients, and GUIs remain 100% compatible without requiring any changes. ## nsmd: * Fix session discovery to not report nested sessions anymore. Also more robust file system error handling. * Command line option --quiet: Suppress messages except warnings and errors * Protect against orphaned clients or daemons when the server, or even a GUI, crashes. * Replace cowboy-slang in info-level OSC with descriptive, technical messages. ## Legacy-GUI: * Fix manpage description and usage with the correct executable name * Fix resizing to very small and back. ( / TheGreatWhiteShark ) ## NSM-Proxy: * Multiple layout and style fixes. Better texts for beginners. ## API: * NSM_API_VERSION_PATCH from 0 to 1 (1.1.0 -> 1.1.1) * Please see API document chapter "Changes in API Version 1.1.1" ## Extras: * This repository now contains extras (libraries, programs, documentation etc.) Extras are technically not connected to the main programs of this repository. There is no dependency to any "extra" nor any license implications. Please read extras/README.md. * nsm.h was moved to extras/nsm.h * "extras/pynsm" is now a part of NEW-SM. It was a standalone git repo until now. Greetings, nils

Reminder: Quarterly Release Pact (next release day 2021-01-15)

by software＠linuxaudio.org

The release pact is an informal agreement to aim for shared, scheduled release dates. We agree to release at least four times a year: January, April, July and October the 15th. To participate you just need to do a release. There is no need to register in advance or ask for permission to participate. A release is an important step in the development and life of software. Users look forward to updates and improvements, but they mean additional work for developers. It is often very hard to decide if and when to release, so developers tend to wait and postpone. There do not seem to be any objective, measurable reasons that could lead to a decision. Therefore we have decided to use time as a basis. Why should you schedule (at least) four releases per year? Developer side: * Incentive to release something. Releases are better than git progress. They get packaged, they indicate a (relatively) good state of the program. * Momentum/Peer Pressure: Other people are going to release, so will I. * Healthy, Active Community: Being in a developer group that you see working (by their releases) is a good motivation to do something yourself. User side: * Announcements: Keep the software in the public eye * Trust. People see that the software is in development and is cared for. * The "last updated" date should never be more than 4 months away and always the current year. * Swarm Marketing: A small release does not have much impact and won't get featured often by news sites. A whole group of software releases demands more attention. At the moment we simply release on the same date, but in the future this could grow closer together. As in: joined press statements etc. Minimum Viable Release: * "Fixed typo in documentation" should be enough. Especially for software that has huge release intervals, like a year or longer, there is public uncertainty if a project is just "working as intended" or dead. A minor release with minimal changes is still a signal to the public that the software is not forgotten. * There is always something to do: Non-Code accomplishments like writing documentation and user manuals are also a (very good) reason to release Where can you announce a release? * Send a mail to linux-audio-announce(a)lists.linuxaudio.org .No registration needed for posting, the list is moderated. * Also send a mail to linux-audio-user(a)lists.linuxaudio.org and linux-audio-dev(a)lists.linuxaudio.org . Cross-Posting releases is accepted. These two lists need registration though. * Submit your release, or the whole software to https://libreav.org * Post to https://linuxmusicians.com/viewforum.php?f=24 * Submit a new link or text post to https://old.reddit.com/r/linuxaudio/ * Add or update your entry at https://gitlab.com/nodiscc/awesome-linuxaudio (see https://gitlab.com/nodiscc/awesome-linuxaudio/-/blob/master/CONTRIBUTING.md ) * Add or update your software to Wikipedia * Add or update your software on this wikipedia list https://en.wikipedia.org/wiki/List_of_Linux_audio_software * Chat with your developer-peers on freenodes IRC channel #lad ( Libre/Linux Audio Developers ) Miscellaneous * How to give version numbers: Semantic Versioning https://semver.org/ * Provide release notes and a CHANGELOG https://keepachangelog.com/en/1.0.0/ ("Don’t let your friends dump git logs into changelogs.") * Provide a real release as tarball and/or Github Gitlab release (resulting in a tarball). Distributions want a stable set of files for packaging. A git tag alone is not stable. * Check your software and information (like README, .desktop file, your own website etc.) if it is up to date. Take inspiration from one of the many release guides, such as https://radek.io/2015/11/23/release-checklist/ * The Documentation Compendium: "Why must you document your project? - Various templates & tips on writing high-quality documentation that people want to read." https://github.com/kylelobo/The-Documentation-Compendium#why_document * Does your software still create (dot-)files directly in the homedir? Start supporting the XDG Base Directory Specification https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
