Hi, Two brand new plugins are included in Harrison Mixbus 2.0.6: A sustainer and a reverb named Gverb+, wich might be a gverb on steroids - both are very good. The thing that is very special here is that this LV2 plugins are only for the Linux version of Mixbos at he moment! Ok, the reason may be that Linux users in general are more geekier and handles potentially buggy new software better those in the other OSes, but it's also another new sign that shows that the Linux desktop user is becoming more and more interesting for commercial vendors. :-) Jostein

Moment with Monosynth video

by Ken Restivo

In case anyone has an interest in watching me play "Moment with Monosynth" from a couple years ago, I recorded a video some time ago, and finally got around to trying out Kdenlive to process/sync/edit it and post it to YouTube, here: http://www.youtube.com/watch?v=zZKjK2P8WrM The performance is a bit more bombastic and wanky, and loses most of the sublety of the original, but it was noisy out (there was a creek nearby) and that encouraged playing a bit too loud. Also, not only am I boring to look at, but I had just finished hiking before recording this, and it was cold and windy, so I was looking especially disheveled. Still, for 10 minutes of work, it at least documents a performance made completely with linux audio/video. Enjoy. -ken

[OT] Videos from a show with my students

by Dave Phillips

Greetings, Three videos from a show we put on in February : Nationwide http://youtu.be/aO6i4jrulrM Comfortably Numb http://youtu.be/K5DwwlCt81Y The Sultans Of Swing http://youtu.be/UC-92sgDVt0 The connection to Linux audio is a bit stretched, I admit, but we do use Audacity to learn the songs in detail, especially the solos. The vids were edited and rendered with Kdenlive running on a 64-bit Arch box. Regarding the audio/video resolution: It is what it is. I didn't make the original recordings, and I applied no processing beyond a/v fades in Kdenlive. Enjoy. :) Best, dp

More stuff from the vaults, PHASEX and AMS insanity

by Ken Restivo

This one is from the end of 2008; it is an outtake from a "Me And My Cronies" CD. It heavily features PHASEX in the beginning and middle, and AMS towards the end. It is highly experimental noisy dissonant electronic jazz. http://storage.restivo.org/music/Cronies/Not_OK_Computer.ogg And it's 14 minutes long. Jeeebus.... what were we thinking? This might be a good track to clear out a party at the end of the night, when you really wish everyone would go home. I made it to about 3 minutes in, then I just couldn't take it anymore. -ken

More experiemntal electronic jazz again

by Ken Restivo

I dug some more in the vaults, and found the following additional recovered tracks from Me And My Cronies. Featuring WhySynth throughout most of the track as a pad, more jammy than dissonant, but it has its moments: http://storage.restivo.org/music/Cronies/Is_That_So.ogg A 29-minute wanky improv opus that goes through a bunch of styles: http://storage.restivo.org/music/Cronies/Fob.ogg And finally, I found a more final mix of "Not OK Computer!" and uploaded that instead (please discard any older versions): http://storage.restivo.org/music/Cronies/Not_OK_Computer.ogg And that's about it in terms of studio tracks from that band which hadn't been published before. Enjoy! -ken

No duplex mode with the EHCI driver and USB hub. Is the problem solved?

by Pablo Fernández

Hi! A few days ago in the alsa users mailing list, Clemens pointed to a recent patch for the EHCI driver [1] [2] for solving the following problem: The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. In connection with this, there was a discussion here some months ago [3]. Some users said that they were not able to get jack working in duplex mode . I also tried to prepare my sister's notebook with a UA25EX and duplex did not work either. I encountered the same problem in the laptop of a friend of mine. In both cases, the computers have an Intel 5 Series/3400 Series Chipset USB2 controller. Jack always says "broken pipe". I have not tried the patch yet but it seems to work if you read the whole thread in alsa-users. Has someone else tried? Joan? Jeremy? Regards, Pablo [1] http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28007.html [2] http://marc.info/?l=linux-usb&m=131973404328622 [3] http://old.nabble.com/USB-audio-interface-and-a-buggy-USB-controller-td2963…

Anyhow from the log I see that the compile was successful, so I hope the program now works for you too :-) Btw., we have found a bug which leads to switches in the rack units not being set after starting the program (effectively changing the loaded state and scratch presets), so I'll make a beta2 release. Downloading and re-compiling is recommended... Many thanks to you and all the people testing the beta release, without them we would not be able to reach a solid release. ciao Andreas

Guitarix release 0.22beta1

by Andreas Degert

Guitarix release guitarix2-0.22beta1 The next shiny new Guitarix version! Guitarix is a tube amplifier simulation for jack, with effect modules and an additional stereo effect chain. Download from http://sourceforge.net/projects/guitarix/ You can find some screenshots and explanations of the new version in http://sourceforge.net/apps/mediawiki/guitarix/index.php?title=EnhancedUI Many things changed in the user interface. Now you can move rack units by drag and drop (reflecting the signal flow), store individual settings for each rack unit and use preset banks with several settings for the whole rack. It's easy to take our "factory presets" and make your own customized bank, or make your own from scratch and share it on the Guitarix forum. There is a new "live play mode" with only the info you need on stage (it's fullscreen, no other penguins around), and a preset picking mode with a foot switch (midi or usb, or if you don't have one even the space bar of your keyboard) and the strings of your guitar to switch settings. Rack units are now put into categories, and two new ones are a noise gate for high noise levels and a univibe emulation. Thanks go to the developer of abGate and Ryan Billing from Rakarrack who helped porting his univibe code and made the inclusion of it possible. This is already too long, please check it out and give feedback if you find a problem, this version is still beta. Please refer to our project page for more information: http://guitarix.sourceforge.net/ download site: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum: http://sourceforge.net/apps/phpbb/guitarix/ here you can find a couple of examples produced by guitarix users: http://sourceforge.net/apps/phpbb/guitarix/viewtopic.php?f=11&t=83 have fun _________________________________________________________________________ For extra Impulse Responses, guitarix uses the zita-convolver library, and, for resampling we use zita-resampler, both written by Fons Adriaensen. http://kokkinizita.linuxaudio.org/linuxaudio/index.html We use the marvellous faust compiler to build the amp and most effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ guitarix development team

[LAA] [ANNOUNCE] aj-snapshot-0.9.6 has been released

by Lieven Moors

Hi all, I would like to announce the release of aj-snapshot-0.9.6 aj-snapshot is a command line utility to store/restore ALSA and/or JACK connections to/from an XML file. The most important change in this release is that aj-snapshot behaves differently in daemon mode. In the previous version ALSA connections were restored continually, and JACK connections whenever the connection graph had changed. In this version, aj-snapshot will restore connections once when it is started, and after that when new ports are registered in ALSA or JACK. You can specify (in milliseconds) how often aj-snapshot will poll for newly registered ports (-p --poll ms). The default is 1 second. This means that you have a lot more freedom to change the connections while the daemon is running, and gives you the opportunity to save (and maybe reload) a new connection state. Other changes include: - added manual file - rewrite of aj-snapshot.c to make it more readable and maintainable, and to have less code repetition. As always, there will be bugs, and I would be very grateful if you would report them on the sourceforge site. direct download: http://sourceforge.net/projects/aj-snapshot/files/aj-snapshot-0.9.5.tar.bz2… aj-snapshot website: http://aj-snapshot.sourceforge.net/ bug tracker: http://sourceforge.net/tracker/?group_id=311291&atid=1310488 feature requests: http://sourceforge.net/tracker/?group_id=311291&atid=1310491 to clone the git repository: git clone git://gitorious.org/aj-snapshot/aj-snapshot.git Hope you enjoy, lievenmoors
