[LAD] Misuse of linuxaudio.org consortium?

by rosea.grammostola

Hi LAD, I would like to raise a issue I've with what I think is a misuse of the consortium linuxaudio.org. As most of you know, the non-session-manager is forked a few months ago. This was not a fork in harmony with it's original developer and a part of the community, who worked on this project for more then 10 years and helped create a unique session environment where many users benefit from until today. Again? Get over it I hear you say. The license gives them the freedom to fork! I agree. But I've personally serious issues with how this is organized and presented and one thing goes beyond my personal views I think. Let's start with my personal view with saying that I don't like how they tried to replace non-session-manager by new-session-manager completely, in a for me 'Orwellian way'. This starts with the naming: Overall name: non-session-manager -> new-session-manager (new?) User interface: non-session-manager -> legacy-gui (legacy?) Ok, now I hear you say: they're free to choose whatever name they want, even if it's bad taste (which is subjective anyway) or if you think it has a 'Orwellian smell'. Moreover, you did issue this already some time ago. I agree. But where it goes really wrong I think, is the way how the name of 'linuxaudio.org' is used in the same deceptive manner. They present the very questionable and debatable fork as if it was released by linuxaudio.org. They release their fork with statements like: "Linuxaudio.org presents: New Session Manager Version x" "Released under the Linuxaudio umbrella" But since when does linuxaudio.org as consortium releases software? Or since when chooses linuxaudio.org as a consortium for a certain version of software? Since when does linuxaudio.org fork software from it's own LAD developers? I think linuxaudio.org has always been neutral about this and it never was a task for the linuxaudio.org consortium to release software or worse, to fork software from community developers and presents it as the 'new' and 'replacement' even while the original developer and a part of the community disagrees. It probably never crossed someones mind to do it this way. What has happened here, is in my view, a misuse of the name linuxaudio.org and people have misused their role as moderator and maintainer of linuxaudio.org and it's github page, to promote their own forked software version of a other LAD developer. Linuxaudio.org should stay neutral here and it should be considered 'unwanted', 'unhealthy' and 'not allowed' for people to use the name linuxaudio.org and maybe even the software structure of the consortium to promote a fork of someone else his work (without consent by the original LAD developer). The main developer of new-session-manager has his own place (laborejo.org) where he can puts his software and so also his fork. That's not the problem. But even if you place it on the linuxaudio github page for some reason, it's utterly wrong in my option, to present this fork as if it was released by the linuxaudio.org consortium. Regards, \r

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.

[LAD] 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

[LAD] 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
