Hi all, A highly overdue release of various improvements and bugfixes cumulated over the last five (!) years is finally out. The main changes are in the Global store that got some handy attributes added to the storage locations, i.e. you can now set a number of repetitions counter. You can also click on a spot within the location buttons to interrupt the automatic progression across locations temporarily. This may improve its usability a bit. Regarding LV2, there is now a X11 UI descriptor provided (thanks to Rui rncbc for a model how to do this in synthv1), but note that the qmidiarp plugins *UIs* are still not self-contained and link to the Qt5 libraries that were used for building, as long as nobody (including me) feels ready to rewrite a library-independent LV2UI for them. They were checked working nicely with qtractor, ardour 6, reaper, carla, jalv and bespoke synth locally, but be warned. The plugin dsps are, however, independent of Qt. Thanks go to Matthew McGuire for adding a phase setting to the calculated LFO waveforms and to all of you reporting bugs and suggesting features. qmidiarp-0.6.6 (2023-04-08) New Features o LFO: New control for phase of calculated waveforms (Matthew McGuire) o Global Store: Each storage location now has a "number of repetitions" property accessible through the context menu. o Global Store: Each storage location now has a "Go here and stay" storage sub-button to force remaining at that location. o ALSA MIDI: Sending MIDI Clock to a specified ALSA port is now available as a new preferences option Improvements o LFO and SEQ: More size and resolution values including odd values Although there is compatibility check in place for saved sessions, this may lead to wrong values for saved LV2 states if someone uses this at all. Long sequences only make sense for lower resolution. Drawing would not be possible with high resolutions and lengths. o SEQ: Improved display of loop marker o SEQ: Increased lower octave transpose range o Global Store: Preferences option to choose whether to store mute states o LV2: a X11 plugin UI interface is now available Fixed Bugs: o Regression: Arp strayed in notes with zero velocity o LV2: restored compatibility with suil > 0.10.2 o Crash when session managers tried to save/restore empty session o Regression with application of compact widget style o Regression when reading files with time module index -1 o Output port count could not be changed on commandline Changes: o Jack-Session support has been removed due to "official deprecation" Download https://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.6.6/qmidiarp-0.6… Github https://github.com/emuse/qmidiarp Website https://qmidiarp.sourceforge.net/

Happy birthday, LAC! 20 years, and..going? Strong?

by Frank Neumann

Hi all, not posting to any of LA* mailing lists often in the last years, but today I thought I should make an exception to point out that it's now exactly 20 years ago that the first Linux Audio Conference or "LAC" for short (then still called "Linux Audio Developer's Meeting") took place at the ZKM in Karlsruhe, Germany. https://lists.linuxaudio.org/hyperkitty/list/linux-audio-dev@lists.linuxaud… Wow, 20 years come and gone so quickly! It's great to see a couple of "early adopters" are still around today here, and many new names have entered the scene in the meantime and left/leave a lasting footprint in it. As a quick "trip down memory lane", here's a short list of things that happened back then: - Takashi Iwai dove into the innards of an ALSA driver - Fernando Lopez-Lezcano introduced the PlanetCCRMA distribution, based on Fedora - Steve Harris explained the concept of a Bode frequency shifter as a LADSPA plugin - Paul Davis held the keynote, AND spoke about JACK, AND shared his experience of writing a DAW that is at the forefront of free, open-source and cross-platform DAWs today. - Dave Philipps looked at the historic development of Linux audio, from OSS to ALSA and beyond - Jörn Nettingsmeier managed to get the audio part of the presentations both recorded AND live-streamed at a time when "streaming" was still a term unknown to most of us. - The term "Linux Sound Night" already existed, but was..perhaps not as musical yet as you might have expected :-). - And, we also learned that schedules are not easy to keep - I believe after the first day we ran some >2 hours late, and people begin to STARVE. - Posing in front of the ZKM "Kubus": https://linuxaudio.de/LAC2003_Posse.jpg For some more memories, see also http://lac.linuxaudio.org/2003/zkm/ Of course, on the downside it has to be noted that Corona has impacted us too - after an almost perfect track record of conferences or mini-conferences every year, 2021 and 2022 didn't see any event happening. There is a certain risk now that it won't recover, but that's in our hands to change (sidenote: I have talked to my contacts at ZKM here in Karlsruhe in January, but they are unable to finance and/or organize an event of this size at the moment - certainly somewhat influenced by current economics, but I am hearing ZKM has actually reduced their headcount quite a bit, and after the recent passing of its artistic-scientific chairman, Peter Weibel, it will have to be seen how his successor, Alistair Hudson, will steer it into the future). Whatever LAC's future will be, free and open-source audio software is certainly flourishing, and will continue to do so. It just would be soo nice to enjoy the results together with real, tangible people :-\. If anyone sees an option for hosting a future LAC, lac-team(a)lists.linuxaudio.org is willing to listen to proposals you might have (or just discuss it right here). Well, the heck - there is no steering committee or anything in place, so I guess the first one brave enough to say "I think we can do it" will get the job :-). I am forever grateful to all the folks who have enriched and continue to enrich our open-source audio life by writing or presenting software, creating documentation and tutorials, hosting (AND attending) conferences like the LAC, and whatever else helps to keep the penguin dancing! Greetings, Frank

mplayer and mpv both crash with jack from libswresample.so.3?

by Peter P.

Hi list, I am trying to work around a problem that I have not experienced in the past (but I can not trace it down to a specific package upgrade): mplayer and mpv both crash when playing back audio files of varying formats (wav, ogg, etc) which have a different sampling rate than jack (tried with both jackd1 and jackd2). The files play fine when using alsa as audio output driver. A gdb backtrace points to usr/lib/x86_64-linux-gnu/libswresample.so.3 which is from Debian's package libswresample3 of version 7:4.3.5-0+deb11u1 I can not downgrade this package to the only other available version (7:4.1.9-0+deb10u1) without removing most of my audio programs. Is this error known? How can I find out more about it, and how could I possibly fix it? Thank you! Peter

MIDI automation in Carla not working? Audio Gain and others

by Gerhard Zintel

Hi, I try to setup a Carla live performance host. My instruments are working fine but I want to use a pedal to control the overall volume of audio output. I connected all synth outputs to the audio gain plugin from falktx (but tried with other plugins as well) and the MIDI output of the keyboard to Gain Control's events-in. So far I was not able to get this plugin MIDI controlled. I don't need MIDI learn but I like to adjust the gain by any cc controller message. I might do something wrong or it is not working. Before I do a bug report I wanted to ask the list if midi control of internal plugins is working for you? In the videos of falktx it seems to work. I am using version 2.6.0-alpha1. Older bug reports mention the problem thus others seem to be hit by the same problem?! So far I use JackMix as an external jack application but it would be much more convenient to use an internal plugin. IMHO controlling plugins by MIDI CC messages is an essential feature of a plugin host. thank you for your time Gerhard

Steinway_IMIS2.2 soundfont (no loops fix)

by Roberto Gordo Saez

This is Steinway_IMIS soundfont, version 2.2. ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2 This version fixes the issue with loops. I hope this is the good one and there are no more remaining major bugs. Marcos is a little busy right now, so he asked me to make this fix. He is thinking to make other improvements, so expect more updates soon.
