[LAD] [ANN] Qtractor 0.9.29 - An Early-Autumn'22 Release batch #3

by Rui Nuno Capela

Hello there, one third and last time, Qtractor 0.9.29 (early-autumn'22) is released! Change-log:: - Capture same time(stamp) note-off tracking and postponing is now on trial, hopefully mitigating a legato issue, reported to MIDI wind instruments (EWI). (EXPERIMENTAL) - Fixed an old window parenting (aka z-level) issue, related to the Add Track and Track Properties dialogs and whether called from the main or mixer menus. - Fixed the out-of-process plugin scanner terminating too soon and sometimes miss some very last results. - Fixed another old bug in MIDI note-off messages not being sent while playing after a loop region. - Fixed a pretty ancient bug in the VST(2.x) plug-in program names inventory, present when building to the VeSTige header (which is still the default). 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.

[LAD] [LAA] XUiDesigner v0.8 released

by Hermann Meyer

XUiDesigner v0.8 released A easy to use tool to generator/design X11 based LV2 Plugin Bundles. Beside that XUiDesigner allow to generate and install GUI's for existing LV2 plugins (so far only Reaper fail to load extra UI's), it support as well to generate LV2 plugins from scratch. Special support is implemented for FAUST dsp files, which allow you to generate a LV2 plugin with X11 based UI by just drag'n'drop a FAUST dsp file into the XUiDesigner interface. This works now as well for MIDI capable faust modules. In any way, you don't need to interference with any of the annoying LV2 implementations. XUiDesigner handle that all for you. The very same is true when you like to implement your own dsp (C++) into a LV2 plugin. Example files for how to create a c++ file for parsing (drag n' drop) with XUiDesigner been included. For later rework the UI a json file will be created which you could drop later on XUiDesigner to load and rework the UI. This may also be usable by other toolkits to create a UI? This release comes with a couple of Bug-fixes and aims to be nearly stable. Here is a introduction Wiki <https://github.com/brummer10/XUiDesigner/wiki/XUiDesigner> entry to show the first steps. Note: Please download the attached XUIDesigner_0.8.tar.gz <https://github.com/brummer10/XUiDesigner/releases/download/v0.8/XUIDesigner…> archive, as only that contain the needed git submodule ( old long time knowing bug on github) as the other files wont be able to build XUiDesigner for you. New in this release: Implement Virtual Midi Keyboard Widget Fix segfault under Wayland Fix several Bugs Implement proper *.cc file parser Add examples for *cc file parsing Project page: https://github.com/brummer10/XUiDesigner Download Release: https://github.com/brummer10/XUiDesigner/releases/download/v0.8/XUIDesigner… Enjoy anyway.

[LAD] Linear prediction

by Fons Adriaensen

Hello all, Any experts on linear prediction here ? During my current holidays in Greece, apart from SCUBA diving, I've been reading up and doing a lot of simulations (in Python) of algorithms related to linear prediction. This has been - I must adimit - a gaping hole in my practical DSP experience up to now. Things work well, but there is one thing that remains strange. It is usually said (see e.g. JOS) that the required order of the prediction should be a bit higher than twice the number of resonances (or formants for voice processing) in the signal to be predicted. This makes sense as each resonance is in essence a second-order process. >From my experiments it seems that at a sample rate of e.g. 48 kHz (indeed much higher than normally used to for speech processing), a much higher order is required to model a low frequency formant at e.g. 350 Hz. What seems to happen at low order is that processing the prediction error (residual) by the the synthesis filter produces and almost perfect reconstruction of the input, but that the filter is actually just doing the -6dB/oct slope above the resonance, while the resonance itself remains in the residual. So e.g. trying to move the formant by modifying the filter will fail. As far as I can see, a prediction order of around 50 is required to correctly model a resonance at such low frequencies. So my question now is this: is the rule mentioned above just wrong, or am I missing something ? Ciao, -- FA

[LAD] installing python extensions

by Fons Adriaensen

Hello all, I have some mixed python/C++ packages, e.g. zita-audiotools and zita-jacktools. To install these I expect the following to happen: 1. The C++ parts are compiled and combined into a *.so file which is a python extension. 2. The *.so and the python parts, any data etc. get installed into the user's /usr/lib/python*.*/site-packages. To make this as easy as possible I provide a setup.py and a Makefile, so that all that should be required is: make; sudo make install Originally this used distutils, when that got 'deprecated' this changed to setuptools. So until recently the Makefile was something like: ---- PY = /usr/bin/python3 build: $(PY) ./setup.py build install: $(PY) ./setup.py install clean: $(PY) ./setup.py clean rm -rf build dist zita_jacktools.egg-info --- Then I got warnings telling me that calling setup.py directly is now also deprecated, and that I should use 'official tools' to build and install. What exactly that means I was unable to find out, but the following seems to work: ---- PY = /usr/bin/python3 build: $(PY) -m build -w install: pip install --force-reinstall dist/*.whl clean: rm -rf build dist *.egg-info *~ ---- But this still produces a warning: > WARNING: Running pip as the 'root' user can result in broken > permissions and conflicting behaviour with the system package > manager. It is recommended to use a virtual environment instead. Now clearly installing things in site-packages requires root, so what is then the recommended method ?? And why the virtual environment (which is used by build anyway) ?? If anyone can shed some light on this mess he/she will deserve my eternal gratitude. Ciao, -- FA

[LAD] [LAA] XUiDesigner v0.6 released

by Hermann Meyer

XUiDesigner v0.7 released A easy to use tool to generator/design X11 based LV2 plugins. Beside that XUiDesigner allow to generate and install GUI's for existing LV2 plugins, it support as well to generate LV2 plugins from scratch. Special support is implemented for FAUST dsp files, which allow you to generate a LV2 plugin with X11 based UI by just drag'n'drop a FAUST dsp file into the XUiDesigner interface. This works now as well for MIDI capable faust modules. In any way, you don't need to interference with any of the annoying LV2 implementations. XUiDesigner handle that all for you. The very same is true when you like to implement your own dsp (C or C++) into a LV2 plugin. You could create the GUI interface, save the plugin bundle, and implement the needed calls to init, activate and run your dsp. This release comes with a couple of Bug-fixes and aims to be nearly stable. Here is a introduction Wiki <https://github.com/brummer10/XUiDesigner/wiki/XUiDesigner> entry to show the first steps. New in this release: implement interim save format (json) <https://github.com/brummer10/XUiDesigner/commit/8e94678ad5e1abde7c8d4dfae05…> (Allow to load and rework the generated UI in XUiDesigner at any time) Project page: https://github.com/brummer10/XUiDesigner Download Release: https://github.com/brummer10/XUiDesigner/releases/download/v0.7/XUIDesigner… Enjoy anyway.

[LAD] DrumGizmo 0.9.20 released

by Bent Bisballe Nyeng

DrumGizmo 0.9.20 Released! DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that has been recorded with a multimic setup. This release was originally intended as a bugfix release, but quite a few features also managed to find their way in. Noteworthy bugs that has been fixed: * Software regression error in cymbal choke code has been fixed. So now choking of cymbals using both directed chokes and after-touch midi events work again as expected. * A compilation error due to an update in LV2 API (we used an obsolete LV2 type) has been fixed, so now compilation should work for everybody again. * Code can now properly be compiled with NSL support disabled at configure time. * Compilation with the modern gcc-11 compiler has been fixed. As usual read the detailed description of all the new shiny features, see the detailed changelog: [1]. And now, without further ado, go grab 0.9.20!!!

[LAD] [ANN] Qtractor 0.9.28 - A Late-Summer'22 Release

by Rui Nuno Capela

Greetings, Qtractor 0.9.28 (late-summer'22) is released! Change-log:: - Complete overhaul of the current host time(base)/BBT information delivered to plug-in types that matter: VST, VST3, CLAP and LV2. - Improved key-signature editing and display on Tempo Map / Markers (time-scale) management dialog. - Fixed plugin selection, when creating and switching initial track type, from audio to MIDI and vice-versa. - Fixed typos and updated some old MIDI GM2 Controller names. - Add current system user-name to the singleton/unique application instance identifier (when explicitly opted in at build configure time). 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.
