Hi, I was frustrated by the font sizes in Calf when used with a high resolution screen. So, I made new styles with bigger font sizes and I put them on github. https://github.com/domichel/calf_big_styles https://github.com/domichel/calf_big_styles/archive/refs/tags/1.0.0.tar.gz The only differences from the original styles are the font sizes. To run 'make' will show you how to install them. If Calf was installed into /usr, it should be as easy than su -c "PREFIX=/usr make install" The next time you run Calf, these styles will appear into the preferences widget. Enjoy, Dominique Calf Studio Gear: https://calf-studio-gear.org/

Jack error

by Fons Adriaensen

Hello all, I get this error when starting any program using jack (1.9.22): BDB2034 unable to allocate memory for mutex; resize mutex region Cannot open DB environment: Cannot allocate memory This occurs only after the system and jackd have been running for a long time (weeks or months). Restarting jackd doesn't help, a reboot is required. I assume this is related to jackd using a Berkeley Database to store optional application and port data. I don't need this functionality, but there seems to be no option to disable it. Also it seems that BDB is no longer maintained. Any hints as to how to avoid this problem ? Ciao, -- FA

python-alsa-midi 1.0.2 released - now with Python 3.11 support

by Jacek Konieczny

Hi, I have just released python-alsa-midi version 1.0.2. The only change since 1.0.1 is Python 3.11 support added. python-alsa-midi provides pythonic bindings to ALSA MIDI – both sequencer and rawmidi APIs. It allows Python programs to use most of Linux MIDI functionality, without the limitations of the portable MIDI libraries. Greets, Jacek

[ANN] Qtractor 0.9.34 - A Spring'23 Release batch #3

by Rui Nuno Capela

One third time, Qtractor 0.9.34 (spring'23) is released! Change-log: - Fixed the snap-to-beat of new notes entry on the MIDI clip editor (aka. piano-roll) due on time signature changes. - Start JACK transport rolling only when metronome Count-in ends. - Fixed an allegedly old and incorrect 0dBfs notch position on MIDI track/buses audio meter sidekicks. - Send/return and Aux-send inserts now show the proper name and the target output bus name on the properties editor title respectively. - Fixed a zero-day blunder that was keeping the real-time process cycle from having the uniform block-size of 64 frames per period; (thus, probably ineffective since v0.9.30). - Multiple MIDI clip tools may now be applied simultaneously, in a single shot, in the following priority order: quantize, transpose, normalize, resize, rescale and timeshift. - Plugin inventory scan now slightly optimized to an allegedly lesser aggressive cache-invalidation algorithm. - Do not send/Preview notes on the MIDI clip editor (aka. piano-roll) when playback is currently rolling. - Send all pending MIDI Note-Off events when playback stops/shuts-off (and/or the Panic! button is hit). - Fixed the internal MIDI file player queue to the highest resolution possible (PPQN aka ticks-per-beat). - Prepping into the next development cycle (with Qt >= 6.5). 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.

EQ Matching

by Florian Paul Schmidt

Hi LAD, I'm working on a (very simple) EQ-matching plugin and wanted to check my understanding/approach and I also have a question. Here's what I do: 1. Analyze spectrum 1 using 50% overlapping blocks each windowed with a Hann window followed by an FFT and then using the absolute value to get the magnitude response of each block. Then finally I calculate the average of all those magnitude responses. 2. Analyze spectrum 2 using the same approach as for spectrum 1 3. Calculate the bin-wise ratio of spectrum 2 / spectrum 1 4. Calculate a linear phase filter response by using the IFFT of the aforementioned magnitude response ratio and then doing the ifftshift dance 5. Calculate a minimum phase filter response from the magnitude response ratio by taking the complex log followed by an IFFT, then folding the negative time components onto the positive ones, followed by an FFT, complex eponentiation and a final IFFT. In code: f = IFFT(exp(FFT(fold(IFFT(log(s)))))) where s is the magnitude response ratio. The code implementing this is found here: https://github.com/fps/fps-plugins.lv2/blob/master/eq_match.h The plugin using it is not done yet. So here are my questions: 1. Are there any glaring oversights with this approach? 2. What is a sensible approach to regularize this approach. If spectrum 1 has any components near zero magnitude then the division is ill suited. It works fine for my experiments with distorted guitars, but I wonder whether I should e.g. just clamp the values of spectrum 1 to something like -70 dB? 3. If the user wants to smooth the spectrum before calculating the responses what would be sensible approaches? I thought about smoothing s with a filter that has a varying bandwidth when expressed in FFT bins or Hz, but constant, when expressed in e.g. octaves or decades. I'm not sure how to do that though. Any thoughts? To finish this email, here is one example (you can play them e.g. by using mplayer on the console): 1. A guitar recording played through some distortion: https://github.com/fps/fps-plugins.lv2/blob/master/input.wav?raw=true 2. The same guitar recording played through some distortion and then a cabinet IR: https://github.com/fps/fps-plugins.lv2/blob/master/output.wav?raw=true 3. The same guitar played through the recovered filter after matching 1 to 2: https://github.com/fps/fps-plugins.lv2/blob/master/matched.wav?raw=true Kind regards, FPS -- https://fps.io

spectmorph-0.6.0

by Stefan Westerfeld

spectmorph-0.6.0 has been released. The new main features are: - SpectMorph now provides a CLAP plugin. - A filter with different filter modes was added. - A new, more flexible modulation system was added. - SpectMorph now provides visual feedback for modulated parameters. Video Tutorial for 0.6.0: https://youtu.be/watch?v=scKrf0o6e6k 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: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. List of Changes in SpectMorph 0.6.0: ------------------------------------ #### New features * New, more flexible modulation system * Added filter with different filter modes * Provide visual feedback for modulated properties * Provide signed .pkg installers for macOS (Intel and ARM) #### CLAP Plugin * Provide CLAP Plugin * Support for per-voice modulation * Support timestamped modulation/automation events #### LV2 Plugin * Support LV2 on all platforms * Fix crashes triggered by Carla (absolute_path/abstract_path returning NULL) * Support newer LV2 development headers #### Minor Changes * Support "Velocity" as modulation source * Make pitch bend range configurable * New Presets with filter: "Cheese Cake Bass", "Liquid Silver" * Sort midi events by timestamp to workaround Bitwig bug * Sliders now support shift+drag for fine editing * Support for Apple Silicon * Avoid crashes if XOpenIM / XCreateIC return NULL (#15). * Fix statically linked plugin data directory location (works in flatpak apps now). * Add dockerized MXE builds for windows, bump compiler version to gcc-12. * Bump minimum C++ standard to C++17 * Fix build on RISC-V (#13) * Use GitHub CI for Linux, macOS and Windows * Change license from "LGPL v3 or later" to "LGPL v2.1 or later". * Minor fixes and cleanups #### Internals: Properties * Add generic property handling * Simplify load/save/gui for properties * Support modulatable properties using ModulationList * Add gui for editing property value and ModulationList * MorphPlan is no longer ref-counted, just one instance per Project * Introduced MorphOperatorConfig objects for cleaner/faster parameter updates #### Internals: Filter * Add two filter types: "Ladder" and "Sallen-Key" filter to output operator * Integrated PandaResampler for SIMD 4x filter oversampling * Support modulation with high time resolution for filter #### Internals: UI Toolkit * Support multiple update regions in UI toolkit * Optimize drawing for UI toolkit * Support "software sprites" for efficient visual feedback * Map Ctrl+Left Click to Right Click on macOS #### Internals: Optimizations * Pass wav set pointers (instead of strings) to morph linear/grid/source. * Avoid fmod() for phase truncation. * Build using -ffast-math * NotifyBuffer: fast dsp thread -> ui thread notifications (no malloc in dsp thread) * Avoid allocations in dsp thread in many cases (retrigger, noise decoder process) * Support optimized SIMD code on ARM (Apple Silicon), code from Peter Johnson (#11) -- Stefan Westerfeld, http://space.twc.de/~stefan
