[linux-audio-user] Ubuntu Studio wiki & hi, I'm new

by Dana Olson

I'm new here, and just wanted to announce my community wiki for using Ubuntu for a DAW. http://www.ubuntustudio.com/ is the URL. If you want to help, sign up and make an account. I'll be closing off public registration soon so that we don't get an influx of bots and malicious users. People will still be able to join by emailing me direct. This wiki is designed to help newbies who use Ubuntu get all of the audio applications up and running. It also is serving as a way to figure out what needs to happen with Ubuntu to get it up to good standards. Mark Shuttleworth and I have been in contact about this, and he is willing to talk to the kernel team to get things sorted out. Yes, Dapper has CONFIG_PREEMPT enabled, but I am hoping to get the CONFIG_PREEMPT_RT patch in there. Anyhow. A bit about me. I've been using Linux exclusively for about 4 years. I started with Mandrake and quickly moved to Debian, and recently I switched to Ubuntu because I decided that I just want to use my system. I still choose Debian Stable for servers though, because I think Debian is amazingly awesome. I've been making music ever since I got my first guitar. I've recorded a lot of stuff, and put anything that I deemed halfway decent up on my website, www.rivironline.com. Everything there was recorded in Audacity, and one song was done with JACK, ZynAddSubFX, and Rosegarden. I am still very new to using JACK and friends, and I look forward to learning a lot. -- Dana Olson

[linux-audio-user] Acid type program

by Vaughan Famularo

Hi fellow groovers!! I am wondering if there is an Acid type of program designed to operate in Linux. That is, a program that can change the tempo of a looped sample but not the pitch. Of all the programs that are worth their weight in gold, I find that Acid is one of them. Thanks for any help in this area Vaughan

[linux-audio-user] Re Acid Type prog

by Vaughan Famularo

Thanks to all who replied to my question about Acid for Linux. I have taken all you have suggested on board and will go through it all in time. Presently, I have an old laptop running '98 with Acid installed. My only real need is to change the tempo of some loops that I have. I don't want to record onto it or use it as a multitrack program. Thanks Vaughan

[linux-audio-user] Ubuntu as a music studio

by Jon Hoskins

Hey all, thought I would share some of my recent discoveries: As demudi 1.2.1 has been lacking a kernel source for awhile and demudi 1.30rc1 refuses to boot on my new hardware I've had to seek alternatives. After reading several threads on using Ubuntu as a music production OS I decided to give Ubuntu 5.10 'breezy' a shot. Installing "realtime-lsm" with module-assistant was easy as pie and I got relatively good latency with the stock kernel, but real improvements came from two things: I decided to give Ubuntu 6.04 "Dapper Flight 3" a run and noticed that #cat /boot/config-2.6.15-4-386 | grep PREEMPT gives CONFIG_PREEMPT=y and has been the same in all the "dapper" kernels I've tried, something that was not enabled in the stable "breezy" kernels. Does this mean the ubuntu guys are looking at releasing a stable kernel with PREEMPT enabled? Anyway the second thing I found was using 'rtlimits' instead of "realtime-lsm". Making use of a small app I found at: http://www.physics.adelaide.edu.au/~jwoithe/ makes assigning realtime access on an app-per-app basis and even user/group basis a breeze. This combination has lowered my latency *under load* to 5.8ms in KDE (Kubuntu is what I installed) and I can squeeze 2.9ms out of it in a very conservative fluxbox or even xfce4 enviroment with no xruns and less than 10% cpu/dps usage (as reported by qjackctl). Most of the good sound apps are available in the repositories as well with the exceptions of Seq24 (conflicting libs) that I easily built from scratch, Freecycle, which I'm still trying to get to compile correctly, and Willem's wonderful DSSI packages. It looks like Ubuntu might have a stable release on the horizon suitable for serious audio work! You are more than welcome to check my blog as well for an up-to-date journal of my ubuntu "studio" experiments and installed software list: http://oktyabr.blogspot.com Best, Jon Hoskins In a world without walls who needs windows or gates? --author unknown

[linux-audio-user] Generative music made with linux, again

by Cesare Marilungo

There's a newer version of the track: http://www.cesaremarilungo.com/download/music/zenmind-0.2.4.ogg (28min, 27Mb) MIDI from PureData->ZynAddSubFx -> jack_capture -> oggenc -q5 I would really really like to receive some feedback especially from those interested in the generative technique. Even negative. c. -- www.cesaremarilungo.com

[linux-audio-user] Homemade music

by Steve D

More homemade music-- Some days ago Thorsten Wilms sent me a great percussion track called Gnomes. I have added melodic and harmonic elements to it and the result can be found here: OGG format: http://www.xscd.com/pub/music/audio/ogg/thorsten-wilms-and-steve-doonan_gno… MP3 format: http://www.xscd.com/pub/music/audio/mp3/thorsten-wilms-and-steve-doonan_gno… I did not edit Thorsten's track at all. I just decoded it into .wav format using oggdec, then imported the .wav into Ardour and began adding tracks. I used Jamin to make the mixdown track, exported it from Ardour, then encoded the exported .wav into ogg (with oggenc) and mp3 (with lame). Criticisms (of the melodic/harmonic elements) is welcome. I have a pretty bad case of flu right now so my ears aren't as good as they should be. ;-) If anyone would like to compare this to Thorsten's original track, that track can be found here: Thorsten's percussion track: http://www.xscd.com/pub/music/audio/ogg/thorsten-wilms_gnomes.ogg Best wishes all, and Thorsten, thank you for this enjoyable Internet collaboration, although I have no idea if you will like what I have done to your track. ;-) -Steve D -- ---------------------------------------------------------------- Doing research is like being in a darkened room, feeling the sides of an object to determine what color it is. -Eli Khamarov ----------------------------------------------------------------

[linux-audio-user] Line 6 TonePort UX1??

by Ketil Thorgersen

Hi On my quest for a good affordable usb solution for my laptop I stumbled upon *Line 6 TonePort UX1 (http://www.line6.com/store/hardware.html?modelID=60). It is a mic, line and high impedance usb interface with a pod in sooftware and virtually no latency monitoring according to the reviews (sound on sound eg.) Of course the effects and software would not work on linux, but would the interface work on linux? Anyone know???? If not wht else should I try? Not more than 200$ Best regards Ketil Thorgersen (living in Sweden by the way) *

Re: [linux-audio-user] Acid type program

by Kjetil S. Matheussen

Ismael Valladolid Torres: > > for VSTs natively compiled on Linux > > Can this be done? Of course it can be done, VST is just a simple header file. But there is no reason to, as almost no programs supports VST, and almost none free non-gui/platform-independent-gui open source vst plugins exist. Additional, theres the political reasons. VST is closely tied to Steinberg, and its license is stupid (and possibly evil as well). So descent open-source people rather use ladspa or dssi instead. (Why hasn't anyone made a ladspa plugin with a GUI by the way? Its really simple just spawning of a gui process program.)

[linux-audio-user] don't manage to install fst

by emanuele ..:: www.rumoridifondo.com ::..

hi folks, i've got a problem with fst. i'm using mandriva 2006 and i have yet installed jack and wine. i've download the file fst-1.7.tar.gz and the vst dsk from steinber site (the file is called vstsdk2_4.zip). the first thing i made is to unzip the fst-1.7.tar.gz into the directory ~. then i unzip vstsdk2_4.zip into the directory ~/fst-1.7 then i enter the directory ~/fst-1.7 and i type "$ make". this below is what the terminal tells me: ----- cp -a `find . | grep 'vstsdk[^/]*\$'`/source/common ./vst cp: impossibile fare stat di `./vstsdk2.4/source/common': No such file or directory make: *** [hackheaders] Error 1 ----- it's like it doesn't manage to find the files he need. anyway i find out that the directory vstdsk2.4/source/common doesn't exist. it's a fst's makefile error, or it's a my error in extract vstsdk? can anyone help me? does fst1.7 requires an older version of vstsdk? thank you all bye emanuele www.rumoridifondo.com
