Hi All. For those of you who like classical music, here's another piece recorded with Aeolus, MIDISH, and Nama. This is for Advent: "My Soul Exulteth The Lord" from the Schubler chorales by J S Bach. https://www.dropbox.com/s/fs20gpdzxftxkz2/Bach_MySoulExulteth_1.mp3 If this doesn't open and play directly from this link, you should get to the dropbox page, where there is a download button. If you have problems, please let me know, as I'm still trying to figure out dropbox links. Please feel free to share it with my name attached, and any feedback you have is welcomed. Enjoy! Kevin

[ANN] Simple Scope LV2 v0.5

by Robin Gareus

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 SiSco.lv2 a Simple Oscilloscope LV2 plugin for scientific measurements. source: https://github.com/x42/sisco.lv2 manual: http://x42.github.io/sisco.lv2/ I recently had a need for a proper software-oscilloscope and there was also the the case about providing a LV2 example to transfer Arrays of LV2-Atoms. The latter is now available as eg05-scope.lv2 from lv2plug.in "Gentlemen, when two separate events occur simultaneously pertaining to the same object of inquiry, we must always pay strict attention." (Dale Cooper) SiSco is not a waveform display but an audio scope which accurately reproduces the signal up to a maximum resolution of about 1μs/pixel @48KSPS (corresponding to 960KHz resolution) to facilitate measurements of an audio stream. While it may seem advanced, it is still rather simple compared to current technology hardware oscilloscopes: * 1-4 channels * grid-resolution min: 50μs, max: 1 sec (max buffer time 15 sec) * per channel horizontal & vertical offset and amplitude scaling * automatic and manual trigger with optional hold-off * two time-axis cursors (shared among channels) * numeric readout (RMS, P-P, dt) per channel * display memory (freeze display - not acquisition - of any channel) It is already available on various GNU/Linux distributions (although maybe not yet the latest version) as part of the "x42-plugin" bundle. Cheers! robin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJSobq5AAoJEKCQvOAs9X8EzwcP/iNZPzBtFkJYO0EHS31uOa+C KmYBMn02IePgWc1V1gHOMDJbavHrjRNpNK4P0YhidbbaE5gFgDb2RKihiak5WV/1 AcCB4V1Cwo3W0v8Vnw6eQ1a4D6ecgGGbTNDghmt/9NTkqZLugy2qRCUP0XAtCgll V0pXiWz5fj56r9xYWG/YX+P/OYAtvPfEA//Kt2EVo8cdQOvfKnil8TWPYURUrZcR wekDByVnInhKbnnVDhGcLazxgCKhTbEEORT/fzECrDXrcO9rI0E/Fu1vUFqvvVzs N5fLjYdap/sgDsIv2Dfw23C5dWepKyQbmiHLJ9HdMkr1Owm6C3UFQ3+LVSluDBmk erfSabL6TSyGSMmCQilRPF2q9yL4tJ14Qx8sYXzWiN5T4auQKoxPEqVToVqutN/I qVabDhei/xbbo0XCY24mxO4i3adeFjIiVFE1upcSpHp8VWM3cpxMVAC3xKmduexM PiTgNRTHSSezrbUaFgrwm/xbNQtnDjh9GgxcexfixIG1/mHxVRNIa4e5QmtSXzpT yINZ+ZtSjpUHZlJSPNHwKUzS0n4AHGotj+tYaW/p4GsGXP7cmUX5OEgLlSjR7Msn SAMDZvsOXCjoFbf0ZYNzu9HVZRYbaB2Tm9QWRUnEs0zM2y6XxfzL9dJhQ9idy4B+ AqdhAtvhFYaNOIiE6eHt =EMjp -----END PGP SIGNATURE-----

Any Linux AT that can handle this?

by Jostein Chr. Andersen

Hi, It's' two really wrong things here: 1: Katie Price should never ever come near a mic 2: The person who's responsible for making this public is an asshole. ;-) Peter Andre might not be perfect here but he does not do an unormal studio appearance. Enjoy the show from 1:13: http://weathersheep.com/peter-andre-katie-price-whole-new-world-without-aut… I'm one of the lucky guys that's surrounded by great singers and I'm not an AT fan. But sometimes it's needed - like the video above ..and when I'm singing for example! Thanks Fons for your Zita-at1 :-) Jostein

Fwd: Focusrite Scarlett 2i2 no playback (jack/pa)

[...] I have one, and apart from general USB audio issues with low latency setups on some kernel versions, it works fine. Can't access the box right now, but I can check my config later if needed. Anyway, first thought: The big monitor dial! You need to turn it up in order to get anything out of the monitor jacks on the rear. (I assumed it was for zero latency monitoring level at first, but only the "Direct Monitor" switch affects that.) -- //David Olofson - Consultant, Developer, Artist, Open Source Advocate .--- Games, examples, libraries, scripting, sound, music, graphics ---. | http://consulting.olofson.net http://olofsonarcade.com | '---------------------------------------------------------------------'

Focusrite Scarlett 2i2 no playback (jack/pa)

by Christoph Kuhr

Hi list, I recently bought a focusrite Scarlett 2i2. I already had a look at http://linuxmusicians.com/viewtopic.php?f=27&t=10055&start=30 and first asked there, without success. So I am reposting it here, with hope that someone has ideas how to get it running. Capturing works out of the box. But I did not get the playback running.

please post: announcing Operacraft premiere

by Ivica Ico Bukvic

Apologies for x-posting... It is my pleasure to announce tonight's premiere of OPERAcraft. Hosted by Virginia Tech's Institute for Creativity, Arts, and Technology, in collaboration with the School of Performing Arts (SOPA), and Linux Laptop Orchestra (L2Ork), this week will feature a premiere and a second performance of a newly produced opera. While both events are sold out, they will be also streamed live online (please see below for a link and additional info). OPERAcraft couples traditional opera with a custom mod of ubiquitous Minecraft designed at Virginia Tech specially for this purpose. Using Linux Laptop Orchestra's pd-l2ork software Minecraft's custom mod is transformed into a full-fledged staging environment, with animated character mouth movement driven through pd-l2ork's speech analysis engine, hand and body gestures, multiple camera angles, camera view mixer, subtitles, behind-the-scenes performer warnings, and a full scene control (fadeouts, transitions, etc.). A 20-minute opera titled "The Surface: a world above" is desiged by and large by high school students, including story, libretto, costume and set design. The project is directed by Prof. Ariana Wyatt, Virginia Tech School of Performing Arts' voice faculty. The music is an adaptation of Mozart's arias performed by Virginia Tech School of Performing Arts' piano faculty Dr. Tracy Cowden. Operacraft mod and supporting pd-l2ork infrastructure was imagined and designed by Virginia Tech School of Performing Arts' and ICAT computer music faculty Dr. Ivica Ico Bukvic and devised in collaboration with Virginia Tech Computer Science undergraduate student Cody Cahoon.

KXStudio 12.04.3

by Dan MacDonald

KXStudio 12.04.3 RELEASE ANNOUNCEMENT KXStudio is a freely downloadable and easy to use GNU/Linux operating system that focuses on audio and video production. The installation disc includes a comprehensive selection of ready-to-run multimedia production software such as the Ardour, qtractor and REAPER DAWs, the KDEnlive video editor, the Renoise, Sunvox and Rosegarden sequencers, GIMP image editor, k3b CD/DVD/BD burner, 100's of effect plugins and virtual instrument plugins and much, much more. KXStudio allows everybody to hit the ground running with an optimized and largely pre-configured free software based digital studio. Multimedia-focused GNU/Linux distributions are nothing new, so what makes KXStudio special? * KXStudio includes Cadence, a suite of custom tools that makes it simple to manage the various layers and features of the various Linux audio sub-systems, integrating them seamlessly via a single app. If you've attempted audio production under Linux previously and struggled, you may find Cadence to be the solution to your Linux audio difficulties. * The easiest way to get going with KXStudio is to install afresh from its DVD ISO but more experienced Linux users have the option of adding the KXStudio software repositories onto an existing Ubuntu or Debian installation so that they may easily install a wide variety of multimedia packages and just take what they need. This allows for many more installation and customization options compared to other Linux distributions and puts the proprietary operating systems to shame in comparison. * GNU/Linux audio plus its installation and configuration is no longer shrouded in mystery thanks to the concise and easy to read KXStudio documentation available at http://wiki.linuxaudio.org/wiki/kxstudio_manual If you'd like to be creative with your computer and free of the demands and limitations of the corporately controlled alternatives, KXStudio is arguably the best option available! http://kxstudio.sourceforge.net/

OT, but IMO really interesting living history: They still produce cassette tapes in Germany

by Ralf Mardorf

In Germany they still produce cassette tapes :). Quality control is done with Studer tape recorders and RFT monitors. Some years ago I got two RFT monitors for less than 50,- € at Ebay :). Seen on German television, today at 18:31 kabel eins. I suspect the Studer studio tape recorders are un-payable and impossible to maintain, so I suspect there will be no long future for this technology. The same factory does produce records too :). The cassette tapes they produce are audio dramas, they didn't mention music. Regards, Ralf
