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'}

[ANN] QmidiCtl 1.0.2 - An Early Spring'25 Release

by Rui Nuno Capela

Hello again! QmidiCtl 1.0.2 (early spring'25) is released! QmidiCt [1] is a MIDI remote controller application that sends MIDI data over the network, using UDP/IP multicast. Inspired by multimidicast [6] and designed to be compatible with ipMIDI for Windows [7]. QmidiCtl [1] was long ago designed for the Maemo [8] enabled handheld devices, namely the late Nokia N900 [9] and promoted to the Maemo Package [10] repositories. Nevertheless, QmidiCtl [1] may still be found effective as a regular desktop application and recently as an Android application as well. See also: QmidiNet [2] - A MIDI network gateway via UDP/IP multicast. Change-log: - Fixed command line parsing (QCommandLineParser/Option) to not exiting the application with a segfault when showing help and version information. - Prepping up next development cycle (Qt >= 6.8) Website: https://qmidictl.sourceforge.io http://qmidictl.sourceforge.net Project page: https://sourceforge.net/projects/qmidictl Downloads: https://sourceforge.net/projects/qmidictl/files - source tarball: https://download.sf.net/qmidictl/qmidictl-1.0.2.tar.gz - source package: https://download.sf.net/qmidictl/qmidictl-1.0.2-5.1.rncbc.suse.src.rpm - binary package: https://download.sf.net/qmidictl/qmidictl-1.0.2-5.1.rncbc.suse.x86_64.rpm - AppImage [11] package: https://download.sf.net/qmidictl/qmidictl-1.0.2-5.1.x86_64.AppImage - Android packages: https://download.sf.net/qmidictl/qmidictl-1.0.2-5.1.arm64-v8a.apk https://download.sf.net/qmidictl/qmidictl-1.0.2-5.1.x86_64.apk https://play.google.com/store/apps/details?id=org.rncbc.qmidictl Git repos: https://git.code.sf.net/p/qmidictl/code https://github.com/rncbc/qmidictl.git https://gitlab.com/rncbc/qmidictl.git https://bitbucket.com/rncbc/qmidictl.git License: QmidiCt [1] is free, open-source Linux Audio [4] software, distributed under the terms of the GNU General Public License (GPL) version 2 or later [5].

NeuralRack v0.1.1 released

by Hermann Meyer

This is the first release of NeuralRack. NeuralRack is a Neural Model loader (based on Ratatouille), it allow to load two model files and run them serial. The input/output could be controlled separate for each model. It supports *.nam files <https://tonehunt.org/models?tags%5B0%5D=nam> with the Neural Amp Modeler <https://github.com/sdatkinson/NeuralAmpModelerCore> engine, or *.json or .aidax files <https://tonehunt.org/models?tags%5B0%5D=aida-x> with the RTNeural <https://github.com/jatinchowdhury18/RTNeural> engine. For tone sharping a 6 band EQ could be enabled. NeuralRack provide a mono input and a stereo output. Additional it allow to load up a separate Impulse Response file for each output channel (stereo). Neuralrack provide a buffered Mode which introduce a one frame latency when enabled. It moves the complete processing into a background thread. That could reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated. NeuralRack could be build as LV2 plug or/and as stand alone application. Stand alone it could be used with JackAudioConnection Kit or with Alsa (pipewire).

[Extended Deadline!] 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 everyone, We're happy to announce that the submission deadline of LAC 2025 has been extended to March 31, 2025! We're looking forward to seeing you in Lyon in June! *Overview* 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. *Important Dates *- March 31, 2025 (March 24, 2025): Paper and Music 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 -- Romain Michon +33 (0) 7 67 39 72 40 https://ccrma.stanford.edu/~rmichon
