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).

Re: [LAD] Simple Pipewire test request

by Alexander

> Maybe pipewire is not run by the same user than the cron job. This was my initial idea, however what I think is more likely is that there is no dbus session for the process to connect to. Are you running PW as a user or system-wide?

[ANN] Vee One Suite 0.9.23 - An Early-Summer'21 Release batch #2

by Rui Nuno Capela

Hello again! The 'Vee One Suite' of 'old-school' software instruments, * synthv1 [1] as a polyphonic subtractive synthesizer; * samplv1 [2] a polyphonic sampler synthesizer; * drumkv1 [3] as yet another drum-kit sampler; * padthv1 [4] as a polyphonic additive synthesizer. Are all being released as the second batch of the so called 'QStuff*' (northern) Early-Summer'21 season. Notable changes for this season are as follows: - Fixed some ages old Glide/portamento potential crash bug (as reported by AnClark, while on synthv1 [1]; also applies to samplv1 [2] and padthv1 [4]). - Add support for LV2 UI Windows platform (by AnClark, also while on synthv1 [1]). - Sustenuto pedal controller (MIDI CC#66) is now implemented. - Fixed old Sustain/Damper/Hold pedal controller (MIDI CC#64) note-off processing. (also implemented new on drumkv1 [3]) - Have some tolerance for buffer-size changes. - All builds default to Qt6 (Qt >= 6.1) where available. - CMake [12] is now the official build system. As usual, all delivered in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. And again in detail... **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.23 (early-summer'21) is released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Whining

by Keith Edmunds

Hi, I'm new to the list. Most of the mails I've seen so far are people whining about systemd. Is that normal for this list, or have I just joined at the wrong time? I really don't need to read about systemd on this list. Thank you, Keith -- Great music, chat and even some wit. Join me every Friday evening at 8pm for Keith's Music Box: Follow: https://www.facebook.com/KMBEngland On Friday go to: https://www.mixcloud.com/live/KeithsMusicBox/

B.Angr - New LV2 plugin

by Sven Jaehnichen

Hi, it's easy to make a new plugin within only four days ... ... if you can use something else. Big thanks to Chris "Airwindows" Johnson. B.Angr is a multi-dimensional dynamically distorted staggered multi-bandpass LV2 plugin. But what the hell does this mean? B.Angr basically consists of four parameter instances of Airwindows XRegion. XRegion itself is a distorted multi-bandpass filter plugin. B.Angr fades automatically or manually between the four parameter instances. The result is a dynamic and heavily distorted sound. See the preview video. Github: https://github.com/sjaehn/BAngr/ Releases: https://github.com/sjaehn/BAngr/releases/tag/1.2.0 Preview video: https://www.youtube.com/watch?v=-kWy_1UYazo <https://www.youtube.com/watch?v=-kWy_1UYazo>

PSIndustrializer 0.2.7-pre2 released

by Yury Alyaev

Hi all, I have made the second preview of Power Station Industrializer v0.2.7 You can download it here: https://sourceforge.net/projects/industrializer/files/ The main new in psindustrializer-0.2.7-pre2 is selectable discretization rate for both playback and WAV export. It also contains some fixes and small improvements. Also, at this stage I announce feature freeze, this means that I won't add new features until 0.2.7 will be released. So I invite everyone to test this pre-release. Industrializer generates synthesized percussion sounds using physical modelling. The range of sounds possible include but is not limited to cymbal sounds, metallic noises, bubbly sounds, and chimes. After a sound is rendered, it can be played and then saved to a .WAV file. Regards, Yury.
