[LAD] B.Oops 1.8.0 - Glitch Sound Effect Sequencer

by Sven Jaehnichen

Hi, a the new version of B.Oops is out now. With really a LOT of new features: * New: Slot shape mode: Controlled by a user-defined shape instead of a pattern * New: Slot keys mode: Controlled by user-defined MIDI events instead of a pattern * New: Pattern randomization * Fx * New Banger * New EQ * Tremolo: Waveform option * Oops: New sample * Default optimization flags `-O3 -ffast-math` for compiling DSP * Improved binary compatibility / portability using static libs * User friendly hiding patterns for inactive slots * New presets * New: Provide binary packages * Bugfixes * Fix pattern Y flip glitches * Correctly X flip merged pads * Fix paste merged pads causing overlaps * Bugfix remove slots may cause segfault * Fix clicks on decay * Bugfix clicked handles if shape changed Thanks to the community for the ideas and suggestions. B.Oops has AFAIK now got more features than any commercial and closed-source effect sequencer! And you can further contribute to this project.

[LAD] PCM channel names API

by Philippe Bekaert

Same context as my previous mail … The RME HDSPe cards have a large number of inputs and outputs for which the standard ALSA channels names and mappings make little sense. Names reflect the hardware interfaces, e.g. Analog.L, Analog.R, AES.1/1 … AES.1/8, ADAT.1 … ADAT.8 etc… and not their function. Right now, the hdspm driver provides a ad-hoc virtual file in /proc/asound/card<n> containing these names. I am looking for a more generic driver <-> user space API for communicating PCM cannel names. Has anyone been facing the same / similar issues? How have you solved it? Are there any ideas, suggestions, preferences concerning this topic? Again looking forward to your feedback. Best regards and thanks in advance, Philippe.

[LAD] huge mixers

by Philippe Bekaert

Dear all, I am working on a new driver for the RME HDSPe cards, which eventually could replace the hdspm driver. These cards have a hardware mixer / matrix router, freely mixing tens of hardware inputs and software playbacks into tens of outputs (8192 mixer controls on the HDSPe MADI). Right now, mixer state (cached by the driver) can be read efficiently in one ad-hoc ioctl call, and individual channels modified through a HWDEP ALSA control element with 3 parameters (input/playback index, output index, gain value). I understand there is a desire to get rid of ad hoc ioctls and am therefore looking for a more generic driver <-> user space API to read and write huge mixer state. Does such more generic huge mixer interface already exist? Has someone been facing this or similar issues in this community? If not, are there any ideas, suggestions or preferences how it should look like? Looking forward to your feedback. Best regards and thanks in advance, Philippe.

[LAD] web expert advice wanted

by Fons Adriaensen

Hello all, I need some advice from a web protocols expert... I want to record the _audio_ part of <https://www.skylinewebcams.com/en/webcam/ellada/crete/rethymno/karavostasi-…> during a long time without wasting bandwidth on the video part, and avoiding being 'timed out' or blocked by 'please whitelist our ads' popups. Anyone has an idea of how to do this ? TIA, -- FA

[LAD] [ANN] Qtractor 0.9.23 - An Early-Summer'21 Release batch #3

by Rui Nuno Capela

Hello again, one third and last time... But happy to announce yet another point release of, drum roll please... Qtractor 0.9.23 (early-summer'21) is out! Changes for this hot season are just but a few, nothing heartbreaking: - Dropped the 'Activate' option on the plug-in Selection dialog, now being as always on by default. - Have some tolerance for JACK buffer-size changes, only prompting to a complete session reload, if increasing in double the initial period size. - Introducing plug-in blacklisting, on user discretion (in View/Options.../Plugins/Blacklist) and on inventory scan (crashed plug-ins are now automatically blacklisted). - Added special support for LV2 UI GTK2 plugins based on Gtkmm 2.4 framework. - All builds default to Qt6 (Qt >= 6.1) where available. - CMake [8] is now the official build system. 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] Is Piperware a successor to Jack/Pulseaudio?

by Yuri

Somebody said on GitHub that "Pipewire is the soon to be successor to Jack/Pulseaudio". I ran a quick search in this ML and couldn't find any mentions of it in the last few years. Is Pipewire viewed like this by the wider community? Does anybody have experience using it? https://pipewire.org/ Thanks, Yuri

[LAD] Simple Pipewire test request

by John Murphy

Could someone please do a simple test on any Pipewire installation set up to use/replace Jack (or shed any light on this). If I run 'pw-record crontest.wav' it works fine, as expected. If I run 'pw-cat 2> errrrr.txt' ditto, of course. If I setup a user cronjob with 'crontab -e' to run the commands (at the start of the next minute or so) the first does nothing, while the second works. Cron writes to /var/log/syslog like: CRON[7694]: (john) CMD (pw-record crontest.wav) rtkit-daemon[1277]: Supervising 7 threads of 4 processes of 1 users (second line repeated) -- John (older than 95.6% of the population).
