[LAU] Still rather confused about Pipewire an interesting midi twists

by Lorenzo Sutton

Hi list and happy 2024! I am running Manjaro (an Arch-based distro). It seems now I have a 'pipewire' package installed, but also pulseaudio. I don't think I have actively tried to install 'pipewire' but maybe it's a dependency for 'something'? Anyways, my current audio set-up is still as it has been for quite a while on my laptop: - pulseaudio for 'eveyday' - jack for audio stuff and software (with a still working script I start only when needed to have a pulseaudio 'sink' - e.g. running jack and wanting to play audio or video from the browser) All of this works as expected and I am still rather unaware of the pipewire intricacies and configurations. One thing I have noticed is that now it seems that alsa midi ports are exposed as jack midi ports as well. Meaning... if I start some notoriously ALSA-MIDI-only applications such as Rosegarden, Pure Data or Qtractor their midi Outputs are shown in QJackCtl in the MIDI (i.e. JACK MIDI) section and are also visible in notoriously JACK-MIDI-only applications like Ardour or Carla, albeit without their port names (Carla puts everything in 'System' and calls the various ports 'midi_capture_1', 'midi_capture_2' etc. regardless of application, Ardour puts everything under 'system' and then does distinguish applications if set to 'show individual ports' but just lists # ports without their names, QJackCtl lists the applications and then for each lists ports as 'midi/playback1', 'midi/playback2' etc.) The most interesting aspect is that besides the naming quirk these ports seem to work meaning that connecting rosegarden to, say, an Ardour MIDI track with a plugin will make noise. That is without going through a2jmidid. a2midid actually works pretty well so I'm not sure what the 'real' advantage would be, but it's still something interesting IMHO. Lorenzo

[LAU] Midi controllers and/or beat makers for Android

by Worik

Friends I'm looking at things like https://www.mixvibes.com/remixlive There are a lot of android tablets in my world and I'd like to try to put them to good use. Some of my collaborators are very shy of computers, but we'll used to touch interfaces But I have been badly burned in theast by apps with terrific user interfaces but no way to connect or export compositions Looking at the app store, it is full of ad ware and marketing crap I do not mind paying. I like paying reasonable prices, and I have a very strong preference for libre Has anybody experience they could share with me?

[LAU] Signing up disabled for all mailing lists

by Jeremy Jongepier

Dear all, Unfortunately I had to disable signing up for all linuxaudio.org mailing lists. This is due to a flood of fake accounts being created that send out subscription confirmations which sometimes get flagged as spam. This in turn leads to so-called Feedback Loop complaints from the abuse team of our hosting service (Hetzner). If we get too much of those we risk getting our mail traffic blocked or ending up on a RBL (Realtime Blacklist). So at the moment new subscriptions can only be done manually through me. This is very inconvenient of course so if anyone knows a better way to shield Mailman3 against bots creating fake accounts then please contact me, thanks in advance! Best regards and happy holidays!!! Jeremy linuxaudio.org admin

[LAU] Using keyframes in Shotcut for visually tracking accordion bass

by David Kastrup

I've recently made "prettified" accordion videos using closeups of both hands. That provides a pretty good distraction from the faces I pull when playing while still not nominally going for the "headless" look popular with some players likely having the same problem. <https://youtu.be/spAP7ODPCyg> Since the left hand moves all over the place with the bass part of the accordion, it requires keyframes to rein that movement in for the closeup. Shotcut recently acquired motion tracker, but so far I haven't got it to work, it doesn't track rotation, and there doesn't seem to be a way to apply results for creating a working closeup crop. So basically I went through the video until each bellows reversal and then straightened up the closeup, creating a keyframe. The greatest annoyance probably was that the rotation angle tended to be in the interval 350° to 20° and I had to manually convert every angle just below 360° into a negative angle in order to keep Shotcut from performing caprioles with the bass side of the accordion between keyframes. An option to constrain the rotation angle to some interval when using the visual controls for straightening things could be useful. I've worked with three cameras: one for the main video, one for each hand. The bass hand camera was tilted in a way to get as large an image as possible while keeping the bass side of the accordion somewhere in frame. On the audio side, this was sampled in Ardour with 96k on an Echo Audiofire card using jackd2 on Firewire (I had to ditch Pulsewire on Ubuntustudio because it got in the way). I employed the Guitarix wrapping of Zitareverb which does a much more convincing job than what Shotcut itself offers as "Reverb". Now if just my playing skills were up to what the tools do... Silk purses and all that. -- David Kastrup

[LAU] jackd: using two different devices for in and out

by Peter P.

Hi list, I discovered that jackd can use different devices for input and output, which is great! I am wondering if there will be the occasional click if these two devices do not have synchronized word clocks? Or is there some clever (resampling?) going on behind the scenes? Thanks! Peter
