[LAU] [Music]: Cooking Meth (an experiment)

by Jeanette C.

Hey hey, whilst on holiday I did not only play the piano and embarrassingly sweet ways. My friend has a very lovely studio with a powerful Linux machine and some outboard equipment. So as an experiment, we did record a very short electronic piece. For now, I'd like to show withgout further comments about the experimental nature, maybe it is obvious after all: http://juliencoder.de/nama/cooking_meth.ogg http://juliencoder.de/nama/cooking_meth.mp3 Feedback is welcome, especially if something strikes you as particularly odd about it. :) Or if you just happen to like to really hate it. :) Best wishes, 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 I can't believe it's what I see That the girl in the mirror The girl in the mirror Is me <3 (Britney Spears)

[LAU] Xrun solved thanks to liquorix kernel

by Banibrata Dutta

Hi, Had been struggling with getting rid of Xruns based on various recommendations like switching to low-latency kernel, turning off WiFi, changing audio interface to other USB ports etc. This is a i5-8400 + 16GB DDR4 + SSD based system running Lubuntu, and with 128*2 buffer-settings. Xruns were seen with almost no non Jack applications running, barring say htop. However tried the Liquorix kernel based on someone's advise on a similar topic, and it seems to have completely solved the issue of Xruns. Now I have perfectly glitchfree recordings, several other applications (some quite heavy) running. Thought, I'd share with the community here. Cheers, BD

[LAU] calf-plugins: why only few have 'byepass' button ?

by Banibrata Dutta

Hi, Had a great time playing around with calf-plugins and doing some live vocals (except the few rare xruns that still do trouble me). However, I noticed that while 'Reverb', 'Chorus did not have a byepass button, few other ones did. What gives ? Also when a signal is bypassed, does the overall signal-chain latency drop (because DSP overheads drop) ? -- regards, Banibrata Dutta

[LAU] How to automatically start zita-j2a/a2j with jack?

by Steven Kruyswijk

Hi all, For a sound playback system I'm putting together, based on a Raspberry Pi 3, I'm looking to have 4 channels of input and output, and to have the system to run automatically at startup. For this, I'm wondering how to (best) execute zita-a2j and zita-j2a; I've tried two methods that don't work: 1. ask Qjackctl to execute the following script after startup: sleep 5 zita-j2a -d hw:CODEC_1 2. execute this script: qjackctl (with auto-start) sleep 10 zita-j2a -d hw:CODEC_1 Executing the zita-j2a manually after Qjackctl has finished starting the jack server does work. Any pointers greatly appreciated! Cheers, Steven -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html

Re: [LAU] Behringer X32 - glitch problems

by nik＠parkellipsen.de

Well, the problem seems to be that there's no dedicated physical USB 3.0 port on my machine, the physical port act as the one or the other depending on what you connect. All physical ports have the SuperSpeed symbol, but none of them automatically connects to the (internal) USB 3.0 root hub if I connect a USB 2.0 device, so I assume there's some logic that detects whether the connected device is 2.0 or 3.0 and connects it accordingly. Like, when I connect a USB 3.0 storage device, lsusb shows it as connected to the 3.0 bus. So I my guess would be, if I use a dedicated (external) USB 3.0 hub, it would be detected as a 3.0 device and routed to the (internal) 3.0 bus, and thus the devices connected to the external hub would be as well. But, of course, that's just speculation. I might just get a 3.0 hub and try.

I'll try this.

[LAU] Behringer X32 - glitch problems

by nik＠parkellipsen.de

Hi, I've been playing around with an X32 recently, and it starts glitching really fast. Like, if i start JACK on my internal sound card (2ch) and SuperCollider with 8 to 24 channels, routing all channels to the 2 outputs, everything's fine. But if I use JACK on the X32 with 8 channels and SuperCollider with 8 channels, it starts glitching as soon as the load increases just a little, using the same programs in the background (ScSynth, SBCL (Common Lisp) using Incudine for OSC scheduling). I've found some settings that work ok-ish, but I still have to be careful not to play too many things at the same time. Using the internal sound card, there's much more leeway. I'm working on Arch Linux, using the latest RT kernel with all exploit-fixing options disabled (https://make-linux-fast-again.com/). No, I'm not using these options for my day-to-day work :D . Has anybody encountered this before ? And maybe knows some way to mitigate this ? Best, Niklas

[LAU] [ANN] Qtractor 0.9.10 - An Autumn'19 Release

by Rui Nuno Capela

Wholly greetings, Without any further delay, here it goes: Qtractor 0.9.10 (autumn'19) is now released! The shortest and maybe TL;DR change-log for this northern Autumn'19 release goes like this: - Fixed the potential crash-effect in switching MIDI output buses on tracks that are set to show audio output monitoring meters. - Fixed initial session tempo override when importing a standard MIDI file (as reported on issue #230). - An alternate time-signature/meter option is being served to the MIDI clip editor (aka. piano-roll) and allowing for some poly-rythm/meter scenarios on a per MIDI clip basis. - Fixed MIDI "overdub" recording on offset clips. - MIDI bank and program settings now propagating to all MIDI track's clips resp. - Fixed MIDI file format default setting other than SMF Format 0. - Escape key may now be used to reset time and tempo/time-sgnature spin-box controls. - Play-head time and tempo/time-signature controls are now featured in MIDI clip editor toolbars (aka. piano-roll); time display format is also separated from the tracks main application view and defaults to BBT as being most convenient. - All items in the MIDI clip editor's event list are now enabled, selectable and editable, no matter the filter settings for the event views. - Added alternate yet non-official CMake build option. - Improved MIDI clip editor (aka. piano-roll) position and size persistence across session state. - Fix HiDPI display screen effective support (Qt >= 5.6). - Mixer, Connections and MIDI clip editor top-level windows shall have no parent, unless when set as always-on-top tool windows. (REGRESSION) - Make sure compiler flags comply to c++11 as standard. 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] setBfree not accepting midi.driver property

by Jeanette C.

Hey hey, I am currently experiencing a problem with setBfree, namely that it doesn't honour the value set for midi.driver and always uses jack. I have tried putting it inside a custom config, set it in the default config (in both ~/.config/setBfree and /usr/share/setBfree and set it on the commandline: setBfree midi.driver=alsa with variations: "midi.driver=alsa" and midi.driver="alsa" No luck. I am running setBfree version 0.8.8. I have just updated to 0.8.9 which still reports as 0.8.8, this is on ArchLinux using the "official" package. Is it that my configuration is out of date perhaps? Can someone verify this or point out a solution, please?
