Discussion: Future CPU-technology vs. realtime audio?

by Michael Jarosch

Hi! Yesterday, I read an article on golem.de (https://www.golem.de/news/ryzen-mobile-5000-cezanne-ist-modular-und-sparsam…) about the future of ryzen (mobile) processors from AMD. Inside the article, it was told that energy saving is done by the processor itself and that the OS will have nothing to do with it. Using realtime apps, I wrote in the comments that I'd really prefer the possibility for userspace interaction and criticized my Intel core i3 8100 not to allow the user to switch to firm frequencies. It was answered that this seems to be the future and that in case of doubt I could switch off frequency scaling in the BIOS. That would mean a lack of comfort to me, as I can't certainly tell, if I am using my machine for audio or another task at the moment of powering on. As soon as frequency switching was introduced we LAU were told, not to use it to save xruns. And as far as I can tell, the rule still valid. Is there a chance in the future that we can stop thinking about it, because it just won't matter? Are we forced blowing loads of energy or do we spent too much time in sluggish UEFI menus? I'd really like to hear your opinion about it (and possible solutions, too)! Greets! Mitsch

mididings alternative for ubuntu studio 20.04 and newer?

by Athanasios Silis

Hi all, I recently migrated to ubuntu studio 20.04 and was wondering why no mididings package exists any more. When sure enough I has to do with dropping python2 and the lack of maintainers for mididings. How have you handled this ? Is there an alternative or do you reinstate python2 and build mididings ? Thank you all, Athanasios

Many Faces of the Gentoo ProAudio overlay

by Brent Busby

This question is Gentoo specific, but there isn't a single place where it would be good to ask, so, for those here who may be Gentoo users: Which ProAudio overlay should we follow these days? I know of at least three of them now! "nilburn": This one says it's "The new Gentoo ProAudio Overlay", which I've been following for awhile, but it never seems to have any changes, so I'm starting to doubt it's the one everyone is really using. Oddly, its web page is at https://gitlab.com/nilburn/proaudio, but the usage instructions on that page tell you to use the URL below instead: sync-uri = https://gitlab.com/proaudio/proaudio.git "tuxfamily": This is the old one, and I _think_ it's supposed to now be deprecated, though I'm on its listserv with no posting access (so I can't ask questions there). It seems to still get activity now and then. Is this still the active overlay? layman -a pro-audio "audio-overlay": Seems small, but with three of them around, what do I know? Maybe this one is the one...? sync-uri = https://github.com/gentoo-audio/audio-overlay.git I actually do have a working system here, and I've got all the programs I need, but I'd still like to know how these overlays all relate to eachother, and where all the action is these days. I'm so confused.

LADSPA/LV2 command line host?

by worik

Friends I am looking for a way to use the LAPSPA/LV2 plugins without the heavy weight hosts (like GuitarX or MODEP) What I am looking for is a programme Z where if I know a LV2 plugin p that takes two control |Int|s (|n|, |m|) is in library L I can invoke |$ Z L p n m| and have it show up in jack so I can control my setup from a script. There are a lot of LADSPA/LV2 hosts, none say on the packet they do this. It may be in the documentation, but it will take time to read the documentation on them all and my suspicion is that it cannot be done with current software. Does any body have any clues? Worik -- If not me then who? If not now then when? If not here then where? So, here I stand, I can do no other root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand)
