[arch-proaudio] New additions since some time this year
by David Runge 24 Jun '19

24 Jun '19

Hey all, I'd like to give information on the work being done so far: Since my last mail regarding the "new packages in [community] topic", I've added a few more: * dpf-plugins * fabla * luppp * non-daw (non-{mixer,session-manager,timeline}) * sorcer * sonic-pi (but that's seriously on its way out again...) * infamousplugins * zam-plugins * rt-tests * giada * artyfx * freewheeling * avldrums.lv2 * blop.lv2 * eteroj.lv2 * fomp.lv2 * mda.lv2 * midi_matrix.lv2 * moony.lv2 * sherlock.lv2 * vm.lv2 * cmt * convolv2 * din * patchmatrix * spectmorph * lmms (updated to latest RC) * sweep * qmidictl * qxgedit * alsa-tools * python-jack-client * python-pyalsa * python-zita-audiotools * python-zita-jacktools * zita-jclient * zita-jclient * aliki * jaaa * jconvolver * jnoisemeter * njconnect * paulstretch * realtime-privileges * japa * lv2file * noise-repellent * setbfree * ams-lv2 * beatslash-lv2 * gmsynth.lv2 * lsp-plugins * libmusicxml * dragonfly-reverb * wolf-shaper * ssr @Albert: pd-lua is still on the list, let's get in touch! @Chris: dexed can also go to [community], I'll look into it! Most of them are in (at least) one of the audio related groups: "pro-audio", "lv2-plugins", "dssi-plugins", "vst-plugins", "ladspa-plugins" or "realtime" You can have a look with: pacman -Sg <group_name> And install the whole group with: pacman -S <group_name> I have done some (minor) revamps of the relevant Arch wiki pages ([1], [2], [3]), but would love to see many more changes (to remove irrelevant data and add actual good and concise examples). Enjoy! David P.S.: If you have suggestions for more additions, let me know!

[arch-proaudio] How to rename an AUR package
by Daniel Appelt 25 Jan '19

25 Jan '19

Hey friendly people, an AUR package that I have created needs an update to a new version. At the same time, I was notified that I should rename it, i.e. add suffix "-bin" as it is a binary package. Could someone please explain to me what would be the best way to do this? A high level explanation should suffice. I am especially concerned about how to let existing users know of the package rename. Many thanks! Daniel

[arch-proaudio] RT-thread issues after update
by Jeanette C. 25 Jan '19

25 Jan '19

Hey hey, after a system upgrade, two days ago, some JACK clients present me with the following warning: cannot lock down memory for RT thread (Cannot allocate memory) This includes mpv and jalv from the standard Arch repositories and Yoshimi from git (not even AUR). Yoshimi has allso been updated since the upgrade. All clients appear to work fine after that, but I haven't given them stress testing. What can it be? Do I need to worry? Can I fix it? Perhaps a config issues somewhere?

[arch-proaudio] LV2/freetype/lilv issue, not sure
by Jeanette C. 25 Jan '19

25 Jan '19

Hey hey, since my upgrade from yesterday night, I have issues loading quite a list of LV2 plugins into mod-host. I get warnings about libfreetype.so.6 a lot: lilv_lib_open(): error: Failed to open library /usr/lib/lv2/fil4.lv2/fil4.so (libfreetype.so.6: failed to map segment from shared object) Some warnings in mod-host do not refer to freetype, but still give the same message about "failed to map segment from shared object". Anyone, can confirm that with other tools? What might it be? Freetype, lilv, ...? Plugins that do not work, include many - if not all - of the calf ones (calf-git), and quite a few distrho (the drowaudio reverb) from distrho-lv2-git. I'd appreciate any help. Best wishes and thanks, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s No one in this world Knows me better than you do So diary I'll confide in you <3 (Britney Spears)

[arch-proaudio] lmms not working with rt jack; vst and midi
by Orm Finnendahl 22 Jan '19

22 Jan '19

Hi, I'm experiecing problems using lmms. I didn't use it before so it might be related to wrong settings. 1. lmms doesn't run with rt mode enabled in jack. The terminal says: "cannot lock down memory for RT thread (Nicht genügend Hauptspeicher verfügbar)" This is strange as the computer has 20GB of Ram and only 2GB are used upon startup. My /etc/security/limits.conf says: @orm - memlock unlimited @orm - rtprio 99 lmms is running with the "orm" userid. 2. Using a VST plugin (The Demo version of the Legend by Synapse) creates nasty audio dropouts when sending pitchbend or other continuous data while playing (with both, the ALSA or JACK non-rt output). The dropouts are clearly related to the incoming Midi (which is using the ALSA Sequencer interface). The cpu load is around 38% when playing and doesn't change if continous data is received. If it was hardware you'd suspect that midi in and audio are sharing the same interrupt... I know this might be a problem of VST with wine in general or something related to the way the synth is programmed but with these clicks the plugin is basically unusable with controllers and maybe someone knows ways to circumvent this problem. The VST plugin seems to be executed by this process: /usr/lib/lmms/RemoteVstPlugin.exe.so \ /tmp/{3e7dc1eb-ba62-4900-9b5f-ec04d555ec23} xembed BTW (regarding versions): My arch system is up to date. -- Orm
