I've seen quite a few adverts for MIDI2 keyboard controllers now, so has anyone tried interfacing with this yet? If so, what sort of problems have you had to resolve. -- Will J Godfrey {apparently now an 'elderly'}

[LAD] dkbuilder-guitarix-lv2-plugins-1.0.1 is out

by Dominique Michel

dkbuilder-guitarix-lv2-plugins is a set of LV2 plugins and faust code generated by dkbuilder. 1.0.1 is the initial release and it introduce the Blow Me Amplifier, a set of vacuum tubes guitar preamplifier and head designed to not compromise the sound. Which is relative because when combined to make a complete amplifier, these plugins offer a lot of gain and saturation. The Blow Me is modelled from a real hardware I made that way because I like punchy saturated and clear sounds, and the best way to get dynamic saturated sounds is when the hardware don't compromise or mess with the sonic quality for financial reason. It is under GPL-3. That release contain the gschem schematics and the resulting LV2 and faust code for use with LV2 and XUiDesigner. As the gain is huge, I made versions of these plugins with different volume curves and defaults, which should make them suitable for different use cases like independent LV2 plugins or with guitarix and that, out of the box. https://github.com/domichel/dkbuilder-guitarix-lv2-plugins Enjoy, Dominique

[LAD] AlsaPlayer 0.99.82 is out

by Dominique Michel

A long awaited release: 0.99.82 I apologize for that delay. I think I miss-understood a message from erikd on the mailing list. The hard work was done by erikd - Erik De Castro Lopo. It consist of a rewrite of the internal of AlsaPlayer in order to suit contemporary coding audio standards with modern computing. https://github.com/alsaplayer/alsaplayer Enjoy, Dominique

[LAD] LAC 2025: Linux Audio Conference 2025 (Lyon, France, June 28-28, 2025) -- Call for Contributions

by Romain Michon

[sorry for cross-posting, please distribute widely] Hi folks, I must say that I feel a little bit ashamed to send this call right after Charles' official announcement of NIME 2025, which has potentially conflicting dates with the event presented below. Really sorry about that... After a few "quiet" post-covid years, Linux Audio Conference is returning in 2025 (https://jimlac25.inria.fr/lac/)! It will take place in Lyon (France) on June 26-28, 2025 under the hospices of Inria, INSA Lyon, and GRAME-CNCM. It will be preceded by the "Journées de l'Informatique Musicale (JIM)" which will also happen in Lyon (June 23-25, 2025). LAC 2025 welcomes scientific, technical, and artistic contributions. It is free and as open as possible. In that regard, we slightly adapted the call below to encourage submissions by people outside of the academic community. While it is possible to submit academic papers (that will be peer-reviewed and published in the LAC 2025 proceedings), open presentations, not necessarily connected to a paper, can be proposed as well. We look forward to seeing you in Lyon in June! *Important Dates *- March 24, 2025: Paper submission deadline - April 18, 2025: Review deadline - April 25, 2025: Notification of acceptance - May 23, 2025: Camera-Ready version deadline - June 23-25, 2025: Journées de l'Informatique Musicale (JIM) - June 26-28, 2025: Linux Audio Conference (LAC) *Call for Papers / Presentations / Demos / Workshops* LAC 2025 invites submissions of papers, presentations, and workshops addressing all areas of audio processing based on Linux and open source software. All submissions and presentations are in English. Submissions can focus on technical, artistic, and/or scientific issues and target developers and/or users. This includes (but is not limited to) the following categories: - Audio and Music Languages - Audio and AI - Audio Hardware Support - Audio Plugins - Drivers, System and Sound Architecture - Education and E-Learning - Games - Interactive Art - Interface Design - Live Coding - Live Performance - Media Art - MIDI, OSC... - Mobile Audio - Music Composition - Music Production - Networked Audio - Physical Computing - Projects Realized using Linux Audio - Realtime Kernel and Linux Distributions - Signal Processing and Sound Synthesis - Sound Spatialization - Standards and Protocols - Video - Etc. *Full Papers* Full papers must be written and presented in English. The length of papers is 4 to 8 pages, with up to 5 keywords, including an abstract of up to 200 words. The abstract will be published on the conference website once the paper has been accepted. Full papers will be available on the website during the conference, and after in the proceedings (which will be published with an ISBN number). All papers are peer reviewed by a committee of experts from different disciplines. Reviewers may suggest improvements to the author(s), require changes in order to accept the submission, or reject it. Full papers will be presented during the conference as in-person oral presentations. *Presentations Without an Associated Paper *LAC 2025 welcomes oral presentations not associated to a peer-reviewed paper published in the conference proceedings. Such presentations are selected by the scientific committee, based on a abstract up to 500 words, with up to 5 keywords. No full paper is required in this category. The abstract will be available on the website during and after the conference. Presentations in this category have the same format as full paper presentations and will hence be presented during the conference as in-person oral presentations. *Demos *Demos are informal project (e.g., plug-in, software, interface, idea, etc.) presentations that will be carried out between the papers presentation sessions. *Workshops *Workshop presentations (max duration of 2h) should be 1-4 pages, with up to 5 keywords, including an abstract of up to 150 words to be published on the conference website. Make sure that your proposal indicates if participants are expected to have a specific level, if there are prerequisites, if you'd like to limit the number of participants, if you have specific technical requirements, etc *Call for Music * We invite submissions of electronic, electroacoustic and mixed music as well as interactive art installations with an emphasis on open source software. A jury will select the compositions and performances to be included in the LAC 2025 conference program according to artistic merit and technical feasibility. Applicants should expect to perform their work themselves and have all resources needed to perform the piece if selected (e.g., instruments, props, other performers, etc.). *Concert Venues* The LAC 2025 musical program will consist of three concerts, two of which will take place at Le Théâtre Astrée (https://theatre-astree.univ-lyon1.fr/qui-sommes-nous/), a concert hall equipped with an 8.4 sound system. For this venue, we are particularly interested in electronic / computer music pieces that will leverage the multichannel set up. The third concert will take place at Le Sucre (https://le-sucre.eu/le-lieu/), an event that will host live coding sets and other performances devised for a night club setting with stereo diffusion. *How to Submit Your Work?* Please, visit the lac website for additional information on how to submit your contribution to LAC 2025: https://jimlac25.inria.fr/lac/ *Contact* For any questions, feel free to contact us at jimlac25(a)grame.fr

[LAD] Ratatouille.lv2 v0.9 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. This release add separate Input control for each Model, makes the delay a delta delay, means it allow to delay the first or the second Model, as needed, and implement support for the 'ctrl' key to allow sample accurate settings for the delay to solve phasing issues between the Models. Ratatouille allow to load up to two neural model files and mix there output. Those models could be [*.nam files](https://tonehunt.org/all) or [*.json or .aidax files](https://cloud.aida-x.cc/all). So you could blend from clean to crunch for example, or, go wild and mix different amp models, or mix a amp with a pedal simulation. Ratatouille using parallel processing to process the second neural model and the second IR-File to reduce the dsp load. The "Delay" control could add a small delay to the second model to overcome phasing issues, or to add some color/reverb to the sound. To round up the sound it allow to load up to two Impulse Response files and mix there output as well. You could try the wildest combinations, or, be conservative and load just your single preferred IR-File. Each neural model may have a different expected Sample Rate, Ratatouille will resample the buffer to match that. Impulse Response Files will be resampled on the fly to match the session Sample Rate.
