edirol usb soundcards
by Bernardo Barros 27 Jul '10

27 Jul '10

Hi, I'm trying to get two soundcards to work. One MOTU UltraLite with FFADO and a USB Edirol PCR-1. No Luck with either. What should I do to configure the Edirol? (Maybe the easier one?) The core installation of planet-ccrma is enough? I tried to start up JACK but the system does not recognize the soundcard. (Fedora 13 64-bit with planet-ccrma). Thanks! Bernardo

Music spin development - are you ready to get involved ?
by Development discussions related to Fedora 26 Jul '10

26 Jul '10

Hi all, I have begun a wiki page to help track our goals for an audio creation Fedora spin: https://fedoraproject.org/wiki/AudioCreationSpinDevelopment , also available from the links at the bottom of the SIG page: https://fedoraproject.org/wiki/Audio_Creation If you want to be involved, please make sure you have a Fedora wiki account (fas), and list yourself in the collaborators section. You'll probably find many areas of the page need flashing out or fixing up; please do so, but also consider the limited time frame before the next Fedora release. A name like "Open Music Workstation" ... or "Fedora Jam", but you can think of better, I'm sure... Meanwhile, as we are trying to show off collaboration, is there any software that allows distant users to jam / create music over the internet ? This would be something really quite unique, compared to other spins. Cheers, David.

announcing envy24control, mudita (*) edition.
by Niels Mayer 25 Jul '10

25 Jul '10

Summary of updates from envy24control 0.6.0 (GIT HEAD) to "1.0.0": (0) After a decade, incremented version to 1.0.0 (**) (1) Implemented missing "Peak Hold" functionality in meters and reimplemented meters for increased efficiency and lower X resource usage. (see http://www.linuxaudio.org/mailarchive/lad/2010/7/12/171535 & https://bugzilla.redhat.com/show_bug.cgi?id=602903 ) (2) All volumes are represented as decibels, including the 0 to -48dB range of the hardware peak-meters, the 0 -to- -144dB attenuation for all inputs to the digital mixer, the 0 -to- -63dB attenuation of the analog DAC, and the +18 -to- -63dB attenuation/amplification of the analog ADC. (3) All gtk "scale" widgets have dB legends; the "PageUp" "PageDown" keys allow rapid movement between the marked levels. (4) Got rid of myriad compile warnings and other minor fixes across codebase. Some screenshots: http://nielsmayer.com/envy24control/Screenshot-Envy24Control-AnalogVolume.p… http://nielsmayer.com/envy24control/Screenshot-Envy24Control-MonitorInputs.… http://nielsmayer.com/envy24control/Screenshot-Envy24Control-MonitorPCM.png ------------ To the ALSA project: please consider this patch to alsa-tools' envy24control (**): http://nielsmayer.com/envy24control/envy24control-0.6-to-1.0.patch (patch to 'envy24control' from GIT trunk/head of alsa-tools) http://nielsmayer.com/envy24control/envy24control-1.0.README (summary of changes from 0.6.0 to 1.0.0) ------------ Those wanting to compile directly, or run a 64 bit linux binary I've built: http://nielsmayer.com/envy24control/envy24control-1.0.tar.gz (full directory, just follow README directions to build/install) http://nielsmayer.com/envy24control/envy24control-1.0-fc12-x86_64.tar.gz (x86_64 binary that should work on fedora12 and equivalent OpenSuse release) I'd appreciate any testing results or comments on this "1.0.0" release. In particular, I'd like some assurance that the dB markings on sliders in "Analog Volume" panel are correct (compared to values reported by 'alsamixer'). I'm looking for testing with following devices (as I think my testing covers code for M-Audio Delta 44 & Delta 66, Terratec Dmx6fire & EWX2496) specifically: M-Audio Delta 1010, M-Audio Audiophile 2496, M-Audio Delta 1010LT TerraTec EWS 88MT, TerraTec EWS 88D, TerraTec Phase 88, Hoontech SoundTrack DSP 24 (all variants). Thanks, Niels http://nielsmayer.com PS: (*) http://en.wikipedia.org/wiki/Envy#In_philosophy :: "mudita, taking joy in the good fortune of another. This virtue is considered the antidote to envy and the opposite of schadenfreude." (**) http://git.alsa-project.org/?p=alsa-tools.git;a=tree;f=envy24control;h=d5a5…

If there is anything I can do to help move the spin forward, just let me know. I am more than willing to help. I think one important aspect may be to put the new version of rakarrack on the spin because the version in the repos is a bit outdated and that particular package is moving very fast. There are instructions on how to build the package on the rakarrack website but I am not experienced enough to know how to incorporate that into the spin.

supercollider+swing on fedora 13
by Bernardo Barros 24 Jul '10

24 Jul '10

Hi all! I'm getting two little troubles here. This is a new computer with a fresh install of Fedora 13, so maybe I did something wrong with installation. 1. When I try to do "yum update" I get: yum update Loaded plugins: presto, refresh-packagekit http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/testin…: [Errno 14] HTTP Error 404 : http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/testin… Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: planetcore-testing. Please verify its path and try again Maybe I did something wrong 2. I installed SuperCollider 3.4 from source. The instalation from planet-ccrma packages did not work for me (maybe because of the same problem?). The other packages besides sc and pd worked well. But... I could install supercollider 3.4 from source, no problems. But I'm not finding the right package dependencies for SwingOSC. It asks "java-6-sun" but I don't find this package in the respos. Any hint/shortcut for this? Thanks!! Bernardo

Re: [Fedora-music-list] music Digest, Vol 44, Issue 13
by William Blackburn 23 Jul '10

I would like to second the notion that a real time kernel would be the best option for this distro. I hate to be a pessimist, but I don't see the point of making a music spin if it is going to have the same kernel as the the standard fedora distro. Anyone can add packages, but a working rt kernel is special. Also, if the real time kernel gets added, I think it may receive more attention and maybe get some nice improvements. If we have to call it a remix and not spin, that is not important to me. What is important is how useful it is to musicians and musicians do not like latency. I understand that the kernel patch can be installed quite easily and this is just my opinion. Please feel free to object to me or to correct me. :) > From: music-request(a)lists.fedoraproject.org > Subject: music Digest, Vol 44, Issue 13 > To: music(a)lists.fedoraproject.org > Date: Thu, 22 Jul 2010 06:20:00 +0000 > > Send music mailing list submissions to > music(a)lists.fedoraproject.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://admin.fedoraproject.org/mailman/listinfo/music > or, via email, send a message with subject or body 'help' to > music-request(a)lists.fedoraproject.org > > You can reach the person managing the list at > music-owner(a)lists.fedoraproject.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of music digest..." > > > Today's Topics: > > 1.

I want to help with the fedora music spin
by William Blackburn 18 Jul '10

18 Jul '10

Hello, I am new to these mailing lists. I usually just hang out in the IRC. Is there an IRC for the new Fedora Music Spin? Anyways. I want to help with it. I got a twitter update with a link to this page http://dlvr.it/2lRXchttp://dlvr.it/2lRXc and I want to help package it. I hope I have sent this to the right address. Cheers and Ciao :) William Blackburn _________________________________________________________________ http://clk.atdmt.com/UKM/go/195013117/direct/01/
