Hi, Does anyone know of an overview of how audio in Ubuntu Studio12.04 works? I've made some mods to other debian builds. Before I spin my wheels a lot jaunted to see the lay of the land. One particular question is how the names of sinks/sources get conjured in jack when I plug in a firewire device. And how the patching gets defined; on this PC the firewire Ports get assigned to all the I/O on the PC. Frontleft, frontright, rearleft, etc.

Re: [LAU] Experiment One - For Sonatina Symphonic Orchestra. Music and a short review of the sample library

by Federico Simonetta

Hi! I'm new in this mailing list. I had your same idea in past days and I wrote a script in python to automatically create sfz files from London Philarmonia sample. Everything is explained here: http://linuxmusicians.com/viewtopic.php?f=4&t=9875 I don't think that it is illegal, because I tell you to download zip packages provided by their own website and I give you a text file not compiled to make a personal use of the zip packages. Everything happens on your computer, so that you are doing it by yourself. Sorry for my english, I'm italian. Hoping this is useful,Federico

Re: [LAU] creating open source sample libs. (Was: Re: Experiment One - For Sonatina Symphonic Orchestra. Music and a short review of the sample library)

by Federico Simonetta

I am sorry for creating confusion with the objects of the mails ... I continue here the yesterday debate about the sfz from London Philharmonia samples. >Btw. >These samples are already in the Sonatina Symphonic Orchestra. > >see here, under "sources" http://sso.mattiaswestlund.net/ > I don't understand why Sonatina uses one samples every three note, while London Philharmonia provides one sample per note. >If there is a script with the best algorithms you might be able to use >and adjust it to different sample libraries. Not a solution for a >opensource sample library primarily, but a solution to use good quality >sample libraries on Linux. Something like that implies a hard code for file names or a strict directories organization to obtain every information needed (for ex: instrument name, note, velocity etc). Every project has different needs.. otherwise, we can think to a tool to make easier creating sfz files, but user will have to insert sample by sample, so it won't be automated.

Very frustrating problem with JACK and exporting through mixbus

by Jason Jones

Just an update: I built a completely new system last week. The system I was using before was an amd64 phenom2 6-core system with ATI graphics. I did a bit of research and found that generally, it seemed that Intel-based systems out-performed AMD systems quite handily, so I decided to test it out. My new system is an Intel Ivy-bridge i7 system with Intel 4500 integrated graphics. Everything in this box is new. I'm using gentoo, and built the kernel from scratch, so as to not have anything from the old system (along with any potential mis-configurations causing problems) leak over to the new system. The first program I put on the system was ardour and mixbus. I copied an old session from the other box over, and loaded it up. When I was finishing up this session originally, on the old computer, it was pegging the DSP meter at 95%-100% consistently, causing me all sorts of headaches. The same session loaded up on the Ivy-bridge system hit it no higher than 55%. That made me smile. Then I tried to export. This is with Mixbus 2.1, by the way. To my surprise, it exported just fine. I then tried to load and export another one, just to make sure it wasn't a fluke. Turns out, it was a fluke. It didn't export, and exhibited the exact same behavior as the old computer. No exporting, the same error messages, etc... No big session was able to be exported since that first one. Made me want to say a few choice words. Anyway... That's the update. I was hoping this problem was isolated to some stupid configuration problem specific to my box, but it wasn't. The good news is - the i7 processor seems to be doing *much* better than the amd phenom2 was. I'm excited to start recording with this new box! I'll probably end up going back to JACK1 due to the exporting problem. Hopefully it doesn't have as many xruns with Intel as it did with AMD. --Jason On Fri, May 18, 2012 at 6:22 AM, Harrison Mixbus < mixbus(a)harrisonconsoles.com> wrote: > > Hi Jason, > > I've been keeping an eye on the list, hoping that one of the JACK devs > would shed some light on this. > > We use Jack2 on OSX and Windows, and exporting seems to work fine there. > All of our Linux development and test systems use Jack(1).

Most boring progrock in my opinion is solo Rick Wakeman. Without the rest of Yes, he's tedious!

I made a thread in the past asking about Creative Commons because my band was interested in the license. The album is now out! We went with Creative Commons BY-SA. Check it out. "Little Street of Happiness" by Platypus Egg. Heavily influenced by genre shifters like Mr. Bungle, Ween, and the Beatles http://platypusegg.bandcamp.com/album/little-street-of-happiness-2

RASP: Music Toolkit

by Brian Hilmers

Hello, this is my first communication here. I'm a former Windows user and recent Linux convert. After switching, I noticed some utilities I regularly used in music production were missing from the major repositories, simple things like tap-temp, delay/Hz calculator, and note-to-frequency conversion. I was looking for an excuse to learn programming so I started working on this "music toolkit" of mine. It's all the stuff I need for making music calculations all in one place (like a producer's Swiss Army knife). Maybe you have a use for it too? Includes: tap-tempo, delay/Hz calculator, song time calculator, note-to-frequency converter, simple frequency generator, and a metronome. http://www.brianhilmers.com/code/rasp/ I'm a novice programmer and this is my first project. Advice and help is welcome. Thanks.

Experiment One - For Sonatina Symphonic Orchestra. Music and a short review of the sample library

by Nils

Full version: http://www.nilsgey.de/2012/08/06/ExperimentOne-ForSonatinaSymphonicOrchestr… tl;dr: Wrote a piece, 1:30 length, to test the Sonatine Symphonic Orchestra. The lib is mediocre and outdated but still the best open source one. Youtube: http://www.youtube.com/watch?v=eJcraiTevSs&feature=player_embedded Flac: http://www.nilsgey.de/uploads/Experiment%20One%20-%20For%20Sonatina%20Symph… This was also a toolchain test: Laborejo -> jack-smf-player -> Lisao+linuxsampler -> jack_capture. No audio mixing (EQ, compressor etc.) involved but ir lv2 on the linuxsampler sum. greetings, Nils
