Join the Debian Multimedia Team! (to improve the state of Linux audio)

by Grammostola Rosea

Hi, Many of the people of the Linux audio community uses Debian or a Debian based distro (Ubuntu (Studio), 64Studio, Musix, Sidux, Mepis etc. etc.). Most of those distro's uses and rebuild the packages of Debian (unstable). There are a lot of audio packages build by the Debian Multimedia Team, but there are also a lot which are not in Debian yet (and so also not in Ubuntu (Studio), Sidux, 64studio etc.) So there is a need for more people who wants to contribute to the Debian Multimedia Team. Again, you don't have to be a plain Debian user to contribute or to take advantage of it. You will help to improve the state of Linux audio in general (at least the Debian based distro's and their community), which will be good for us all, but also for newbies who are not able yet to build all the packages themselves to enjoy all the nice things Linux audio has to offer. Also note that it is possible to build Debian unstable packages on other distro's then Debian itself (search for Pbuilder on the Internet for instance)! It will also be good for the Linux audio developers and their software. It would be more easy to install, use, test and enjoy the software by the Linux audio community! There are a lot of people these day who has an own (PPA) repo. This is ok, (and maybe it will be a good thing if the Linux audio developers make their packages available as much as possible in a Debian unstable repo/package, so it can be used on Debian and it is easy to rebuild it for Debian based distro's), But to bundle forces and to get safe, stable and quality packages, joining the Debian Multimedia Team will get much better quality packages and you will help far more people then having your solo private repo... *Why the Debian Multimedia Team? * 1) Because they want to improve Debian for music production! 2) Debian has an flexible, fast and easy package management 3) A lot of people use Debian (based) distro's, Debian itself, Ubuntu (Studio), 64studio, Sidux, Mepis etc. 4) You will learn to build quality packages 5) You don't have to become a Debian developer (DD), you can just become and stay a package maintainer. *What can I do?* 1) Build or improve packages for the Debian Multimedia Team. It's recommended to maintain packages you use yourself often. 2) Report bugs and wishes 3) Join the Debian multimedia team mailing list: http://lists.debian.org/debian-multimedia/ *Where can I find more info?* Wiki: http://wiki.debian.org/DebianMultimedia Packaging: http://wiki.debian.org/DebianMultimedia/DevelopPackaging Existing packages which needs help: http://wnpp.debian.net/ Debian New Maintainers' guide: http://www.debian.org/doc/maint-guide/ (!) Bugs: http://bugs.debian.org/cgi-bin/pkgreport.cgi?which=maint&data=debian-multim… It would be great if you choose one package which you uses a lot and maintain it for the Debian Multimedia Team! It would improve the quality of Linux audio and it will help the whole community! Kind regards, \r ps. If you like to join, please subscribe to the Debian Multimedia Team mailinglist and ask for more information: http://lists.debian.org/debian-multimedia/

Re: [LAU] Enable/disable toggle in jack-rack with Behringe FCB1010

by Leandro Leal Parente

I use Jack-rack with my Behringer BCD3000, but in my midi controller effect button is a note and the Jack-rack doesn't aceppted it. So I converting it on midi PC with qmidiroute. When I pressed effect button, qmidiroute ( http://alsamodular.sourceforge.net/) convert this midi note in PC and send to Jack-rack. In Jack-rack that midi PC controls enable button of specified effect. But when I released the effect button the enable button goes off, so for enable button goes on I have to keep pressed effect button. It works for me.

Re: [LAU] Newer USB audio interfaces

by Bill Allen

Interesting and helpful. Probably a stupid question but is the Fast Track Pro USB 1 or 2? I couldn't find any indication on the MAudio site.

another eeepc success story

by James Stone

Following on from Ken Restivo's amazing work getting RT linux working on the eeepc, I decided to have a go. I am using a 701, which I have slightly overclocked using the eee.ko module (required on my eee to boost voltage to get SD cards working reliably YMMV). http://code.google.com/p/eeepc-linux/ I patched the latest 2.6.29.2 kernel with the rt11 patch, and just built it... Running Jack with qjackctl, I can set periods to 128, full duplex, 44100 and get no xruns. I have to set prio to 89, and force 16 bit. Importantly, I also have to kill NetworkManager and NetworkManagerD or I get xruns. With all this, it seems really solid. I am running ardour with no problems.. 6 individually recorded tracks writing to the SD card seems to work fine. James

Newer USB audio interfaces

by Bill Allen

I noticed in the discussion on Ken Restivo's EEE-PC that he is using the MAudio FastTrack Pro. I had looked at that device, but when I looked at the Alsa soundcard matrix, it wasn't listed. Is it working out of the box? Another USB device that I thought looked good was the E-Mu 0404 USB. It is listed as not implemented yet. Is anybody using that out of the box yet? Any other ideas? I'm looking to replace my venerable Edirol UA-20 with something a little more modern since I've never been able to get its midi and audio working together. In advanced mode, midi works but no audio and vice-versa. Best regards, Bill

Comparisons among sample rate conversions

The link below belongs to a site where there are SRC comparisons of most popular audio processing software. Nice work I guess. http://src.infinitewave.ca/ -- Arda EDEN Cumhuriyet University Faculty of Fine Arts Department of Music Technology Sivas/TURKEY

whither Phasex ?

by Dave Phillips

Greetings, The Phasex site is now a porn list. The author of this neat synth seems to have disappeared. I suggest that someone put the last source code on a public ftp site. Best, dp

Re: [LAU] [LAD] whither Phasex ?

by Dave Phillips

Greetings, I've taken my own advice and put the source tarball on the linux-sound.org site. I've also retrieved and updated the original Web page. It's now here : http://linux-sound.org/phasex/ Please advise if you see anything there that should be changed or added. Like maybe some links to demos ? Best, dp

USB Interface/Mixer

by Bob van der Poel

Here's my setup which needs improving :) 1. Playing midi files in a laptop and routing the audio to a mixer, then to PA 2. Have 2 mics plugged into the mixer. I'm thinking that using a USB audio device will make the audio (much?) better ... but I really need to haul yes-another-piece-of-gear around like I need more free gigs. So, is there a usb device which will let me connect to the laptop for the midi output, let me plug in a couple of mics and route the entire mix to a PA? Or PCMCIA? I'm not interested in spending a small fortune on all this. I've got decent enough gear here in the office/studio and if I get a paying gig I don't mind hauling. But, when we go to a seniors home or farmers market for an hour or so, the motivation lags. Thanks. -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

SuperCollider 3.3 released

by Dan S

SuperCollider is an environment and programming language for real time audio synthesis and algorithmic composition. It provides an interpreted object-oriented language which functions as a network client to a state of the art, realtime sound synthesis server. Many changes since 3.2; here are some headlines: * scvim and sced are now part of the main bundle, for using vim or gedit as your sc code editor * New UGens added: * BEQSuite filter UGens (popular set of nice-sounding filters) * PartConv (efficient frequency-domain convolution) * SendReply (sends arrays from server to the language client) * VDiskIn (like DiskIn but with variable rate) * LFGauss * Buffer recording/playback UGens used to be limited to 16-channel; now they can handle massively multi-channel audio * LocalBuf framework allows synths to create/free their own “private” buffers, simplifying buffer management in many situations * GUI system updates: easier syntax, plus a major update of GUI documentation * Various behind-the-scenes efficiency improvements, for a sleeker audio server that can do more on a given machine Source packages for linux can be found at http://supercollider.sourceforge.net/downloads/ Ubuntu debs are on launchpad: https://launchpad.net/~supercollider/+archive/ppa Best, Dan -- http://www.mcld.co.uk
