NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows available as Stand alone application, and in the Clap, LV2 and vst2 plugin format. It supports *.nam files <https://www.tone3000.com/search?tags=103> and, or *.json or .aidax files <https://www.tone3000.com/search?tags=23562> by using the NeuralAudio <https://github.com/mikeoliphant/NeuralAudio> engine. For Impulse Response File Convolution it use FFTConvolver <https://github.com/HiFi-LoFi/FFTConvolver> Resampling is done by Libzita-resampler <https://kokkinizita.linuxaudio.org/linuxaudio/zita-resampler/resampler.html> New in this release: * implement option to move (drag and drop) EQ around Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. It features a Noise Gate, and for tone sharping a 6 band EQ could be enabled. Additional it allow to load up a separate Impulse Response file for each output channel (stereo), or, mix two IR-files to a two channel mono output. Neuralrack provide a buffered Mode which introduce a one frame latency when enabled. It could move one Neural Model, or the complete processing into a background thread. That will reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated.

SpectMorph 1.0.0-beta3

by Stefan Westerfeld

SpectMorph 1.0.0-beta3 has been released. This version contains a new pitch detection algorithm for the instrument editor and it can read mp3 files. Compared to 1.0.0-beta2 there are mostly smaller fixes, but since some of them address critical problems we strongly recommend updating to beta3 if you use a previous beta. There is a tutorial on YouTube for the new features in the 1.0.0 series: - https://youtu.be/mwVUsuOTcN0 Feedback for any issues you might experience with the beta version is appreciated. What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS (Intel and Apple Silicon), with CLAP/LV2/VST plugins. Under Linux, there is also JACK Support. Links: ------ Website: https://www.spectmorph.org Download: https://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. List of Changes in SpectMorph 1.0.0-beta3: ------------------------------------------ ## SpectMorph 1.0.0 beta3 #### New Features * Implement pitch detection algorithm for instrument editor and smenc (#31). * Support mp3 format for static plugins and builds with new libsndfile. #### Instrument Updates * Trumpet, French Horn: ping pong loop, better tuning * Bass Trombone: ping pong loop, volume normalization, tuning * Alto Saxophone: ping pong loop #### Reduce Memory Usage after Unload * Avoid global constructors / destructors. * Use our own TextRenderer instead of cairo to be able to free font cache. * Ship necessary fonts on macOS for TextRenderer. * Free various tables and other bits of static data when unloading. #### Fixes * Don't crash on invalid utf8 during conversion (use replacement char). * Fix crash caused by multiple threads modifying control events. * Fix CLAP's get factory implementation (#30). * Various ASAN / UBSAN fixes. * Fix RTSAN issue: make FFT realtime safe. * Avoid allocating memory in RT thread if events need to be sorted. * Fix (unlikely) LineEdit crash. * Validate input for smenc -m and other utils where an integer is expected (#31). * Fix smooth tune performance for long input files. * Build system updates. * Convert manpages to markdown. * Documentation updates. -- Stefan Westerfeld, http://space.twc.de/~stefan

[LAA] Linux Audio Conference LAC2026: June 18th-20 in Maynooth, Ireland

by Frank Neumann

Hi all, just wanted to share the good news here that in 2026 the LAC (Linux Audio Conference) is taking place again, on June 18-20 (Thu-Sat), this time coming back to Maynooth (Ireland) where it was already hosted in 2011. Victor Lazzarini, conference organizer, asked me to help in spreading the word about it, so here we go. All details on music&paper submission process, deadlines, travel and accomodation etc can be found at the conference web site: https://lac26.mucs.club/ Greetings, and please feel free to spread the word wherever possible, Frank PS: Jeremy: Can you put a corresponding hint into https://lac.linuxaudio.org? Thanks!

[LAA] Virtual MIDI Piano Keyboard 0.9.2 Released

by Pedro Lopez-Cabanillas

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changes in v0.9.2: * Swedish translation updated, thanks to Karl Jonatan Nyberg * kmapdialog: new readonly column showing note names * New settings toolbar * Fix #35: wrong default initialization value for CC8 (Balance) Compilation minimum requirements for all platforms: * CMake 3.16 * C++17 compiler * Qt6 >= 6.2 or Qt5 >= 5.9 * Drumstick 2.10 Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments. Thanks. Copyright (C) 2008-2026, Pedro López-Cabanillas and others. License: GPL v3 More info: https://vmpk.sourceforge.io Downloads: https://sourceforge.net/projects/vmpk/files/vmpk/0.9.2

[LAA] Loopino v0.5.0 released

by Hermann Meyer

Loopino — New Release: Unified Time, Multi-Engine Character & Advanced Stretching This new Loopino release marks a major step forward in timing accuracy, tonal consistency, and sampler character. By integrating *librubberband* (standing on the shoulders of giants), Loopino now features *unison note lengths across the entire keyboard range* — meaning every pitch now preserves its rhythmic identity while being played musically across the full scale. In practice, this means: your micro-loops, slices and textures no longer shrink or stretch unpredictably when played higher or lower — they stay locked in musical time. Alongside this, Loopino now introduces *multiple sampler engine simulations*. Each engine emulates different playback behaviours, interpolation styles and internal timing characteristics inspired by classic and modern samplers. This allows you to choose not only /what/ you play, but /how/ it behaves — from tight, modern precision to lo-fi, characterful vintage motion. These additions build on Loopino’s already powerful creative toolkit: drag-and-drop sampling, on-the-fly recording, pitch tracking, micro-loop generation, non-destructive wave shaping, multiple analogue-inspired filters (Moog, Oberheim, Wasp, TB-303), modulators, vibrato, tremolo, chorus & reverb, preset handling, WAV export in key, up to 48-voice polyphony, and a highly flexible standalone environment with ALSA support and command-line configuration. New in this Release * High-quality time-stretching powered by *librubberband* * *Unison note lengths across the full keyboard range* * *Multiple sampler engine simulations* for different playback characters * Continued performance, stability & workflow refinements Loopino is no longer just a sampler — it is a time-aware, character-selectable, performance-ready instrument that blends sampling, synthesis, and musical timing into one creative engine. Project Page: https://github.com/brummer10/Loopino Release Page: https://github.com/brummer10/Loopino/releases/tag/v0.5.0 Happy sampling.
