Hello

by Gilberto Borges

Hello. My name is Gilberto Andre Borges and I am from Brazil. I am happy to subscribe this list and I stay here because I am Musix Project's co-ordinator. I am postgraduate in Music, in the area of concentration Music Education, for the University of the Santa Catarina State. At present, I work with teachers' formation in the Public Net of Schools of the city of Florianópolis, in the Santa Catarina State, Brazil. I am an investigator in the area of Music, where I am developing one dissertation about Music Education and Free Software. In Brazil, the adoption of free software in the public schools is stimulated by the federal government and, recently, a federal legislation made the teaching of music compulsory in the basic education (first nine years of school education). I believe that adding efforts up the whole community of musicians who use free software will leave winning. Forgive for me some mistake of orthography or grammar, since I have practice little with the English language, but I speak very quite Portuguese and Spanish, so that I can help with these languages.

hello from pure:dyne

by aymeric mansoux

Hi LAT! Thanks for setting this list :) Quick intro for those who do not know about pure:dyne. pure:dyne is a live distribution for artists and musicians. With artists and musicians we mean persons working in the field of media-art/software-art/net-art/... using GNU/Linux as a platform to create installations, make performances, give workshops, teach GNU/Linux in art schools, and also use pure:dyne as an OS for small media/artlab. The project has been initially started by GOTO10, a distributed collective of artists, and it is now growing to a group of 8 persons. We provide "studio" applications from Gimp to Ardour, but our focus and packaging is around software such as Pure Data, Supercollider, Csound, fluxus, Processing, Arduino and more exotic things :) We recently switched to Debian as our core system to build the liveCD, and we aim to stick to it as much as possible, which means that we intend to move our packages from our repos to Debian eventually, this will be done with help of Free and I believe part of the Debian Multimedia group effort. Right now, we use a mix of 3 repos for our system, lenny, multimedia (debian-multimedia.org repos) and ours. So far so good :) We have been contacted by Daniel after we announced the project was switching to Debian and started to talk with Free to see what kind of technical overlap the 2 projects had so we could try to limit dupe works in the long-term. Part of this discussion we met Daniel during one of our code sprints and moved the discussion forward with concrete initiatives, like the idea to have such a list for distribution maintainers and advanced users to exchange tips and tricks on linux audio tuning. We also talked about the idea of a set of common kernel config that could be reused by different audio/video distros. Part of pure:dyne we have always put our config on SVN, http://code.goto10.org/projects/puredyne/browser/live/kernel (this is the one currently on the liveCD btw) and we have started to make some kernel benchmarks and audio optimizations page: http://code.goto10.org/projects/puredyne/wiki/KernelAndSystemOptimization I think it would be very useful if the 1st projects of this list were: - a common place for all the distro maintainers to write a common tuning doc (wiki.linuxaudio.org?) - the creation of a repository with a couple of kernel config and patches that would be common to our distros - a benchmark protocol for testing audio settings and kernel config/versions Let me know what you think! a.

testing rosegarden 1.7.0 and 1.6.1

by Marcos Guglielmetti

Hi folks! All the files are here: http://www.musix.org.ar/ogg/mgg2008/lentitud/ On Musix 1.0 R4 (debian etch+backports) Rosegarden 1.7.0 used to crash when recording MIDI from my sb live (it begins to crash when recording the 4th DSSI track), so, I installed 1.6.1 (ftp://ftp.ourproject.org/pub/musix/deb-testing/) and went almost Ok, sineshaper produced some strange "hang" to the rosegarden sequencer (a note remains, and when I rewind or forward it makes all the system slow... so I killed rosegardensequencer, and re-started rosegarden) apt-cache policy sineshaper sineshaper: Instalados: 0.4.2-1 But, it was a beautiful recording session: quantize, change note velocities, move and fix some recordings was really easy, smooth and comfortable, I love Rosegarden :D I disabled the USB ports on my PC because they have the same IRQ as my SB Live, then, I also used icewm because it's light. rtirq status PID CLS RTPRIO NI PRI %CPU STAT COMMAND 1340 FF 85 - 125 0.1 S< IRQ-10 EMU10K1 374 FF 75 - 115 0.0 S< IRQ-1 i8042 373 FF 74 - 114 0.0 S< IRQ-12 i8042 5 FF 50 - 90 0.0 S< softirq-high/0 6 FF 50 - 90 1.3 S< softirq-timer/0 7 FF 50 - 90 0.0 S< softirq-net-tx/ 8 FF 50 - 90 0.0 S< softirq-net-rx/ 9 FF 50 - 90 0.0 S< softirq-block/0 10 FF 50 - 90 0.0 S< softirq-tasklet 11 FF 50 - 90 0.0 S< softirq-sched/0 12 FF 50 - 90 0.0 S< softirq-hrtimer 13 FF 50 - 90 0.0 S< softirq-rcu/0 61 FF 50 - 90 0.0 S< IRQ-9 acpi 290 FF 50 - 90 0.0 S< IRQ-14 ide0 293 FF 50 - 90 0.0 S< IRQ-15 ide1 619 FF 50 - 90 0.0 S< IRQ-8 1215 FF 50 - 90 0.0 S< IRQ-6 1289 FF 50 - 90 0.0 S< IRQ-7 parport0 1774 FF 50 - 90 0.0 S< IRQ-11 eth0 3325 FF 50 - 90 0.0 S< IRQ-4 serial uname -a Linux musix1.0r4dvd 2.6.23-rt1 #1 SMP PREEMPT RT Sun Oct 14 15:17:12 EEST 2007 i686 GNU/Linux cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 8 model name : AMD Duron(tm) stepping : 1 cpu MHz : 1800.247 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow up ts bogomips : 3602.98 clflush size : 32 free total used free shared buffers cached Mem: 350504 342596 7908 0 14960 146908 -/+ buffers/cache: 180728 169776 Swap: 2771132 20912 2750220 Spanish article: http://www.mastermagazine.info/articulo/13251.php -- Marcos Guglielmetti - www.musix.org.ar Software Libre para Artistas Y al final, como tan astutamente fue observado en la década de 1860: "Todo lo que era sólido se ha desvanecido en el aire, y el aire y era algo que todos sabíamos que podíamos respirar libremente". Y así nos encontramos confrontando un sistema de poder basado en las ideas de las relaciones de propiedad que la tecnología de los propietarios ya estaba haciendo obsoletas.
