Re: [LAU] Multiple asynchronous JACK chains resampled?

This seems like a pretty complicated scheme. What is your actual end goal? What do you want to happen differently than your current situation? Is it just that at 85% DSP usage your system is not capable of running anything additional, and you want to run additional processes? If that is all, then first try adjusting the latency of your current setup to be equivalent to the latency you will have with the Rube Goldberg setup of a stack of dinky little ARM processors connected together with resampling through a network. If you read the zita-njbridge man page you see that the minimum latency is the sum of the periods of each asynchronous connection, so at minimum double your current latency, plus resampling latency, plus network delay. So for a start set your system latency to 2x or 3x what you currently have and see how that works. -- Chris Caudle

What exactly is JACK DSP % usage ?

by Jonathan E. Brickman

Eight-core, 4GHz AMD, 8G RAM. Running a lot of things all at once, 60 high-demand tones out of two Yoshimis (120 total), JACK DSP % usage is 85%, but CPU usage through htop is a different thing, one CPU is being kept by one Yoshimi at 64%, the rest less than 15% and some down to 1-2%. JACK is not stressing any CPU! So my primary question is, what is JACK DSP % usage, what are its limiting factors? -- Jonathan E.

[ANN] Vee One Suite 0.7.3 - The Ninth beta release

by Rui Nuno Capela

Vee One Suite 0.7.3 - The Ninth beta release -------------------------------------------- The 'Vee One Suite' aka. 'the gang of three' old-school software instruments, synthv1 [1] polyphonic synthesizer, samplv1 [2] polyphonic sampler and drumkv1 [3] drum-kit sampler, are now released in their ninth official beta iteration. All available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. In common to all three comes the spartan change-log: - Avoid out-of-bound MIDI events as much as possible, coping with LV2 plug-in hosts that feed/run them in on border line circumstances (as reported by Thorsten Wilms, on suspected Ardour looping crash/bug, probably fixed already, thanks). - Tentatively safe defaults are being introduced to internal OUT FX buffer-sizes, as read from JACK buffer-size changes and LV2 block-length instantiation bound options. - Added application keywords to freedesktop.org's AppData. The Vee One Suite are free, open-source Linux Audio [9] software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later.

Music recorded with Linux: c2015-19a

by jonetsu＠teksavvy.com

Greetings, This piece is a longer one that develops a bit slowly. I made up a tag for this: AcousticWaveRock. The instruments are acoustic guitar and acoustic bass guitar, to which a few synths sounds were added as well as drums and percussion, sampled from a Korg Microstation JazzBrush Kit. What's new in this project, as I progressively learn, is the use of what is called 'multing' tracks, eg. taking bits of a track and copying/moving them to another track. This was used to move some guitar parts to another track where a delay, for instance, was applied. It could have been done with automation although using another track is simpler IMHO, especially when a different EQ is chosen. No automation curves to make. Also got recently a headphone amp (Behringer HA400) that's connected to jack's 3 and 4 playback outputs (1 and 2 still remain connected to the M-Audio studiophone speakers), the audio card being a 1010LT. It is now possible to listen in stereo ! Previously the headphone jack from the M-Audio speakers was used, and it did not give much of a stereo effect. The switch from one set of playback device to another is done using Ardour's monitor output choices. Also, there's the use now of two mics for each of the acoustic instruments, each mic recording to its own track. There's an AT2020 in omni mode, no cut, and a M-Audio Pulsar (not Pulsar II). This piece 'goes forward' in the sense that themes only occurs once. When they occur they are repeated, but they do not come back later. The supporting structure stays the same though. Cheers. https://soundcloud.com/nominal6/c2015-19a

multitrack export midi type 0 (gramophone2) issue

by Benoît Rouits

Hello, I have written generative composition with a chomsky grammar parsed by and *old* program called gramophone2. Unfortunately, my tests composition have multitrack but gramophone2 generates midi type 0 files (1 merged track). So, all midi sequencers i tried does only import track #1 while there are 3 or 4 in the midi file with different speeds (i'm playing with yet another phasing music). It may be a grammophone2 bug, but before to dive into the code (if i find it) how could i convert the generated midi type 0 into a type 1 so that tracks speeds can be aligned ? With the hope the question is well asked and not out of topic. - Benoît

Jconvolver example files and jconvolver packages

by Ralf Mardorf

Hi, after an off-list correspondence with Hermann, I noticed something, that might explain the difficulties those new to jconvolver have got. [rocketmouse@archlinux ~]$ pacman -Ql jconvolver jconvolver /usr/ jconvolver /usr/bin/ jconvolver /usr/bin/fconvolver jconvolver /usr/bin/jconvolver jconvolver /usr/bin/makemulti "Ralf_Mardorf commented on 2016-02-20 16:22 Hi, as it turns out by two LAU thread http://lists.linuxaudio.org/pipermail/linux-audio-user/2016-February/104030… http://lists.linuxaudio.org/pipermail/linux-audio-user/2016-February/104075… some users experienced difficulties using jconvolver. I couldn't understand why, since I've got examples how to do this, but then I noticed that the AUR package doesn't install the examples from the tarball. Consider to add those examples.

Hermann Meyer <brummer-(a)web.de> schrieb: What you talk about is so called multi file support, and thru, that isn't implemented, but, that didn't mean it is not stereo.

It's _not_ really stereo, since there seems to be no way to use a left.wav and a right.wav. So assumed you like to use jconvolver as reverb, it will not sound that fantastic, as it sounds when writing a config with an text editor. _____________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-user

Ardour session with plain ALSA, without JACK

by Ralf Mardorf

Hi, if I chose "Audio System: JACK" I can start a new session, but if I chose "Audio System: ALSA", I get "Failed to open audio device". Perhaps I make a mistake. There's no special reason that I want to use ALSA instead of JACK, I just want to test it. I never tried to do it before, with any other version of Ardour. $ pacman -Q ardour ardour 4.7-1 $ grep jack /var/cache/aur/current/ardour-4.7-1-PKGBUILD --with-backends="jack,alsa" \ --libjack=weak \ $ amidi -l;aplay -l;arecord -l Dir Device Name IO hw:0,0 HDSPMx579bcc MIDI 1 **** List of PLAYBACK Hardware Devices **** card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO] Subdevices: 1/1 Subdevice #0: subdevice #0 **** List of CAPTURE Hardware Devices **** card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO] Subdevices: 1/1 Subdevice #0: subdevice #0 Regards, Ralf
