digital input to stereo receiver, maybe through ethernet

by Dan Hitt

Hi All, I have a pretty ancient stereo receiver that i'm thinking of replacing or supplementing with something newer. It looks like some of the new receivers have an ethernet jack, as well as usb. For example, see these Denons: https://usa.denon.com/us/news/news/177 What i would like to do is get a receiver like that, and put it on my network, and then use it to play audio. Ideally, it could show up on the hosts on the network as some kind of device (like /dev/receiver) to which audio files could be catted. Maybe that's not realistic, but i sure would like to be able to use the receiver from multiple hosts (probably running debian or a derivative) and not have to go through any 3.5 mm or other analog stuff anywhere (not on the computer, and not on the receiver). I wouldn't have to have simultaneous access from the hosts, but would like to plugging and unplugging cables (although i would not want wireless). (Right now about the closest i am to this is with some usb logitech speakers that my system detects and can direct audio to, but i'd like to go through a receiver so that i could use better speakers. However i want to stay all digital and not take any steps through the analog world, and would like to be able to do it from more than one computer.) Does anybody do this? I feel like the answer must be yes, because why would even consumer electronics have so many connectors if not (???). Anyhow, thanks in advance for any advice on whether this can be done, and how to do it (or how close you can get to doing something like this). dan

LinuxSampler/telnet issue

by Jeanette C.

Hey hey, I've recently discovered a challenge with my LinuxSampler. I use LSCP scripts and usually load them like this: cat script.lscp | telnet localhost 8888 It always worked. But now, the connection is opened and closed and nothing else happens. This is very likely connected to my move to Arch Linux. Copying and pasting the script into a telnet terminal works. Any idea why the cat | telnet couldn't work? It would be very much appreciated. Thanks and best wishes, Jeanette -------- When you need someone, you just turn around and I will be there <3

Using multiple sound cards with jack

by Bill Purvis

I currently use qjackctl to control Jack, but would like to be able to use more than one sound card at a time, or at least be able to switch from one to another without having to restart jack. Currently, the QjackCtl Connect window shows a single stereo audio output referred to as 'system'. Is it possible to have more than on audio output here?

Introduction to Praxis LIVE (Athens) - March 31st

by Neil C Smith

Hi All, There's still some spaces available on a Praxis LIVE workshop I'm leading in Athens this Friday (March 31st) as part of Electric Nights - http://www.medeaelectronique.com/electricnights/portfolio/an-introduction-t… Please spread the word if you know anyone who might be interested. An Introduction to using Praxis LIVE Friday, 31st of March, 17:00 Tutor: Neil C Smith This workshop will introduce you to Praxis LIVE, an open-source, hybrid-visual tool for creative coding. Easily build projections, interactive spaces, audio-visual performances, and much more. The first half of the workshop will cover basic project setup, the intuitive graphical patcher interface, and the range of available components for manipulating audio, video and data. After this, you can continue to explore the graphical aspects of the software, or learn how to “drop down” into code to create your own components and live-code audio/video with Processing, Java and GLSL. http://www.praxislive.org/ Participants must bring their own laptop Workshop duration: ~3 hrs Participation fee: 30 euros Send an email to workshops[at]medeaelectronique.com specifying the workshop you want to participate in Many thanks and best wishes, Neil -- Neil C Smith Artist & Technologist www.neilcsmith.net Praxis LIVE - hybrid visual IDE for creative coding - www.praxislive.org

Music: L'Art du théorbiste

by Giso Grimm

Hi all, an Early Music CD completely produced with Ardour was finally released at Brilliant classics: http://www.brilliantclassics.com/articles/l/lart-du-th%C3%A9orbiste-music-f… You may find a short video of one of the pieces on youtube: https://youtu.be/NG9ttY74P1o The musician is explaining his concepts here: https://youtu.be/zs5fVM4m-Pc Actually, the audio recording was back in 2010. The video was recorded a couple of weeks ago, in the same church where we recorded the music - thanks to Robin Gareus for all his LTC stuff! Without that it would not have been possible to synchronize audio and video. And of course thanks to Paul and all other ardour-contributors! A picture of the recording setup can be found on this forum, somewhere down on the page: https://community.ardour.org/node/3248 Have fun! Giso (I have no commercial interest in the sales of this CD.)

[ANN] Vee One Suite 0.8.1 - A Spring'17 release

by Rui Nuno Capela

Great news! The 'Vee One Suite' of old-school software instruments, respectively synthv1 [1], as a polyphonic subtractive synthesizer, samplv1 [2], a polyphonic sampler synthesizer and drumkv1 [3] as yet another drum-kit sampler, are once again out in the wild! Still 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. The common change-log for this dot release follows: - Fixed a probable old miss about changing spin-box and drop-down list not reflecting changes immediately into the respective parameter dial knobs. - Fixed middle-button clicking on the dial-knobs to reset to the current default parameter value. - Help/Configure.../Options/Use desktop environment native dialogs option is now set initially off by default. - Added French man page (by Olivier Humbert, thanks). - Make builds reproducible byte for byte, by getting rid of the configure build date and time stamps. And here they go again! **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.8.1 (spring'17) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
