Does anyone know of software that can generate MIDI messages from a touchpad? The idea would be to send CCs to a sequencer or soft synth, but being able to send it to an external hardware device would also be very useful. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.

SpectMorph 1.0.0-beta1

by Stefan Westerfeld

SpectMorph 1.0.0-beta1 has been released. The main changes are: - WavSource: added formant preserving algorithms for repitching vocals - KeyTrack: new operator to combine instruments by note range - Envelope: new operator to generate arbitrary modulation envelopes - LFO: support arbitrary user defined curves There is a tutorial on YouTube for the new features: - https://www.youtube.com/embed/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-beta1: ------------------------------------------ #### New Features * WavSource: support two formant preserving algorithms for repitching vocals. * New operators: - KeyTrack - can be used to combine instruments by note range. - Envelope - to generate arbitary modulation envelopes. * User defined curve editor for KeyTrack, Envelope and LFO. * Add presets using the new operators: - KeyTrack Choir Ah/Oh - StringBrass Fusion * JACK CC values are now interpreted per channel (allows polyphonic modulation). * Support double click to reset properties to default value. #### Fixes * Apply midi channel bend to new voices. * Make portamento affect filter cutoff key tracking. * Fix problems with WavSource paths stored by LV2 plugin (make Ardour archives work). * Fix getting the initial click events / focus plugin UI on macOS under Bitwig. * Fix invalid access to past last vector element (#24). * Make PandaResampler work without problems in ASAN builds. * Refactor leak debugger to fix possible crashes caused by global destructors. * Do not ship sample data in "1 Instrument WavSource" preset. #### Internals: Improvements * Generate and store spectral envelopes in each AudioBlock for formant correction. * Improve the strategy for portamento synthesis (more accurate and less CPU usage). * Propagate portamento frequency to sources. * Randomize start phase per default to improve "Harmonic Resynthesis" quality. * JACK: use two audio outputs to be able to implement stereo support later on. * Add fast vectorizable log2 approximation (based on Tims version from Anklang). * Phases in LiveDecoder, IFFTSynth: change from float to uint for performance reasons. * Various minor performance optimizations. * Minor LV2 meta data updates (port groups, avoid port resizing extension). * Use newer compilers: g++-14 for windows, g++-13 for static linux plugins. * Support automatically downloading instruments from configure. * Avoid using std::mutex in hard RT code. #### Internals: Minor Changes * Refactoring: - Deduplicate morphing code from MorphGrid and MorphLinear. - Use shared pointers for GenericIn/GenericOut classes (RAII). - Get rid of `sm_clamp` / `sm_bound` (-> std::clamp). * Improve CI support (use debug-cxx, asan, ubsan, test static build, avoid fftw planning). * Add post install test which tests audio output for all presets after installation. * Validate LV2 feature arrays. * Support user defined scripts in testmidisynth test. * Improve error messages for preset loader. * Build cleanups: remove libbse code, simplify Qt build (remove smsampleedit). * Update CLAP version to 1.2.1. -- Stefan Westerfeld, http://space.twc.de/~stefan

[ANN] Qtractor 1.0.0 - An Unthinkable Release batch #3

by Rui Nuno Capela

Hi all, it's finally here, Qtractor 1.0.0 (the unthinkable) is released! Change-log: - Making up the unthinkable (aka. v1.0.0) - General plugin scan/cache optimization. - Improved legibility to all clip title labels (color contrast). - Save/load the correct order and labeling of audio/MIDI send/return pseudo-plugin inserts. - Fixed a display and port-name filtering issue that was present ever since on the Connections widget. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Upgrading pipewire

by Alf Haakon Pietruszka Lund

Hello list! I'm currently testing Linux Mint Debian Edition (LMDE) 6 "Faye" to see how pipewire performs. However, the first stumbling stone is that LMDE 6 ships with pipewire 0.3.65. It does have backports enabled though, where version 1.0.7 is available, but I can't understad how to upgrade. This is what I tried: 1. Open synaptic and search for all pipewire packages with version 0.3.65. 2. Mark all the packages to use version 1.0.7 (Package > Force version...). Synaptic then automatically marks some other packages for upgrading or removal. 3. Despair at the error message E: Unable to correct problems, you have held broken packages. E: Unable to correct dependencies Anyone here had a go at this before, or have pointers on how to succesfully upgrade? Best regards, Alf

Linux Audio Conference (is back) 2025

by Stéphane Letz

Hi everyone, This is just to let you know that after a couple of years of absence, Linux Audio Conference will take place in Lyon in 2025 on June 26-28. For those of you who speak French, it will be preceded by the Journée de l'Informatique Musicale (JIM) on June 23-25. The call for contributions will be posted on the conference website by the beginning of September: https://jimlac25.inria.fr/ In the meantime, save the date ;). Cheers, Stéphane (for the jimlac25 committee)
