[LAU] [New music] Enantiomorphic, also new album

by Jeanette C.

Hey hey, I've just released a new synthwave piece. Well, I suppose this is synthwave, inspired by the likes of Tangerine Dream and perhaps the Berlin school. For the audiophile: http://juliencoder.de/nama/05-enantiomorphic.ogg and http://juliencoder.de/nama/05-enantiomorphic.mp3 There is also a youtube "video: youtu.be/6up7aLhsIG4 The new album (or EP) is called "Audierotic Synthspiration" (and every time I type this I wish I hadn't called it that :) ): http://juliencoder.de/nama/audierotic_synthspiration The other five songs were posted here before during the past year or so, they range in genre from EDM, to dubstep, drum & bass, synthpop and - now - synthwave. Feedback is always welcome. Best wishes and enjoy, 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 There's just a thing or two I'd like you to know <3 (Britney Spears)

[LAU] MOTU AVB discussion from LAC

by Max

Fernando Lopez-Lezcano discussed the pitfalls of using the MOTU AVB external audio interfaces with Linux in his paper [1] and also in the keynote at LAC-19. Let's start another thread around this card. Fernando mentioned that different firmwares expose different issues, but downgrading is possible. Issues are: 1. Channels are not persistent and swap around. 2. Total number of channels has been reduced in newer firmwares. 3. An endless card aquisition loop between Jack and Pulseaudio caused by the long time the card needs to switch sampling rate. 4. Seemingly erratic behavior, opening the device fails, fails again, again, then works suddenly. I have a couple of questions and experiences. Is there a table of the firmware versions somewhere (linuxaudio wiki?) which tell me which versions has which features (removed)? Are all the Class Compliant models having the same quirks as listed above? For example the MOTU UltraLite AVB versus the MOTU 624 AVB? Is it possible to use the Thunderbolt port to connect the card to a Linux computer? Why can't I tell ALSA to use only the first 2, 4 whatever channels of the device? I can only open the device if all channels are connected. Is this always like that or is that a limitation of MOTU's implementation? On my laptop with only one USB bus, If I connected the MOTU 624 AVB and then another high speed usb device, the computer could not connect the later, because the MOTU reserved all the bandwith for itself. Connecting the other device and then the MOTU worked. [1] http://lac.linuxaudio.org/2019/doc/lopez.pdf Max

[LAU] [ANN] Qtractor 0.9.8 - Yet Another Spring'19 Release

by Rui Nuno Capela

Hi all, Too hot to make any boring introduction, so let's get this straight: Qtractor 0.9.8 (spring'19) is released! The changes for this yet another seasonal release are as follows: - Plugin-lists and respective plugins state may now be exported and/or imported as XML files. - When in Drum Mode, Key and Scale are meaningless and thus functionally disabled from the MIDI clip editor (aka. piano-roll). - MIDI clip editor's View > Ghost Track menu option is now finally a reality: show any existing MIDI track and its respective clips in the background as dimmed, semi-transparent aka. ghost events. - Minor update to Debian packaging control file. - Make sure partially selected clips are reset to whole when Shift/Ctrl keyboard modifiers are in effect, to prevent extraneous clip splits or cutaways afterwards. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

[LAU] Soundcraft notepad 12fx

by soffioalcuore＠posteo.net

hello, I refer to a topic which had shortly been discussed last year (https://www.spinics.net/lists/linux-audio-users/msg110169.html). somebody wrote he was already in contact with soundcraft about the problem that in linux there's no possibility to choose the source of the channels 3&4 of the soundcraft notepad 12fx to be send via usb to the computer. I would like to ask if there's news about it. thank you very much! christoph

[LAU] Why doesn't Jack work in duplex mode?

by François-Xavier Thomas

Hello all, I posted this on Reddit a while ago, but I hope you folks might have some more luck than people on r/linuxquestions. I'm trying to find out why Jack2 works with playback-only as well as capture-only, but not both. If anybody has any clue as to why that is or how to start debugging it, I'd be grateful! * `jackd -d alsa -D -d hw:1,0`: Duplex mode, doesn't work. * `jackd -d alsa -C -d hw:1,0`: Capture-only mode, works. * `jackd -d alsa -P -d hw:1,0`: Playback-only mode, works. I'm using the default settings (1024 frames/period with 2 periods/buffer @ 48kHz sampling rate). The sound card is a `bytcrrt5640` (`hw:0` is another card connected to HDMI outputs). Pulseaudio is using 48000 frames/period with 2 periods/buffer @ 48kHz for comparison, and appears to work fine on the exact same soundcard (I used `pacmd list-sinks` and `/proc/asound/card1/**/hw_params` to get that info). By "doesn't work", I mean : when trying to run `jackd` in duplex mode, a slight "pop" sound can be heard from the speakers, then the dmesg logs fill with the following line: intel_sst_acpi 808622A8:00: sst: Busy wait failed, cant send this msg `jackd` then freezes, and nothing short of `kill -9` can make it go away (which incidentally makes the speakers emit another small "pop"). The dmesg line is the same mentioned in https://lkml.org/lkml/2018/2/18/117, but I did not find a lot of info on it. Cheers, François-Xavier

[LAU] Two M-Audio Delta 1010s available

by Joe Hartley

Now that I have settled in with my Babyface Pro and my Soundcraft mixer, my Delta 1010s sadly have no place in my studio anymore. Since one of them came my way for free in exchange for documenting the capacitor upgrade process, I'd like to return the favor and offer them for free to anyone on the list who would like them. You only have to cover the cost of shipping. Each is a full unit with PCI card, breakout rack panel, DB25 cable, and power supply. Both breakout panels have had the power cap upgrade as documented at https://delta.brainiac.com/delta1010capfix.html Please email me off-list if you'd like these. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh(a)brainiac.com Without deviation from the norm, "progress" is not possible. - FZappa
