[linux-audio-dev] [admin] maintainership passes on...

by Joern Nettingsmeier

hi everyone! i'm very happy to announce that marc-olivier barre will be maintaining the linux-audio-* lists from now on. let me take this opportunity to ask for a few more volunteers to moderate linux-audio-announce. get this: for years, brilliant minds like ingo molnar, robert love and lee revellhave been toiling with the kernel for a few measly microseconds gain - as a linux-audio-announce moderator, you can cut latencies by hours if not days. how is that for a claim to fame? please get in touch with marc-olivier. it's been a pleasure to participate in this linux audio community for all those years, and i have profited immensely from the great work done here! thanks everyone, and i hope to see you around at LAC 2007! best wishes, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 if you are a free (as in "free speech") software developer and you happen to be travelling near my home, drop me a line and come round for a free (as in "free beer") beer. :-D

More robust IMO than the din connectors now used for midi interconnects, however the cabling itself can't help but be more fragile when subjected to the rigors of a jam session with bodies walking on them all night. And that has to be a consideration else the first users will get discouraged at the high cable failure rates and revert, particularly if they have a tin ear and can't hear what to many of us would be an extremely obvious improvement. But I like that idea, a lot. Maybe some enterprising LAD people could get together and spec something like a midi interface running over firewire, complete with the repeaters so it can be daisy-chained just like midi can be, and hopefully release it into the PD as a new midi-2 interface standard. And design it such that it never, ever gets into the snails trail of the 31,250 baud interface it uses today. -- Cheers, Gene

Preprocessed source stored into /tmp/ccDt1tHZ.out file, please attach this to your bugreport. scons: *** [frontends/fltk_gui/CsoundGlobalSettings.o] Error 1 scons: building terminated because of errors. John ffitch has successfully compiled Cs5 for AMD64 with FLTK support, but he used GCC3. I've tried the various options for scons, but got no joy whenever I used Word64=1, the build always dies at the same point. Yes, I do see the compiler report request, but when I searched Google I found documents stating that this particular error was supposed to be resolved already by GCC4. Does anyone see what needs to be done to get past this point with the FLTK stuff in Cs5 ? Any suggestions for a fix ? I'll gladly furnish any other imformation required, just let me know what's needed. Best, dp

[linux-audio-dev] Re: alsa, oss , efficiency?

by Danni Coy

cool it guys... It sounds like the person who asked the question only really needs to use sound in a really simple way and that performance is not a huge issue.... I would like to ask what other libraries are being used in your application.. how portable you want it to be...

[linux-audio-dev] Annouce: initial release of Miditoys...

by Danni Coy

Miditoys is a small program I wrote so I could use some of my more interesting peripheral devices as midi instruments.... So far I have a reasonable attempt at a midi control surface using a playstation 2 style gamepad... and the beginings of a drumkit using the same device... This program is still very much in its infancy... There is very little in the way of documentation - If you are interested or you run into problems I please contact me More details at: http://miditoys.sourceforge.net

[linux-audio-dev] The Linux Audio Vision

by Carlo Capocasa

Hi, all! Contact me at: theman-AT-carlocapocasa.com As you might know I am a full time linux audio musician, and in the process of forming a company to produce music with linux audio exclusively and release it licensed CreativeCommons Attribution ShareAlike in OGG Vorbis format exclusively. (With the option to keep up with whatever standard the Free Community agrees on) I had one of my first sessions with Carlo, my partner today, and there is no doubt on my mind we will be very well received by a LOT of people. Lyrics are along the lines of the practical new age movement, which focuses on achieving goals using the mind as a primary tool. My goal is to create a company, that is a little bit different than other companies in that it has a broader definition of profit motive. The primary profit motive is satisfaction, while it is trusted that money will find itself a way to follow as well. Currently, this means specifically to simply sell some products on a musician's web site that has a lot of traffic because word of mouth draws people who want to download free music there. Contact me at: theman-AT-carlocapocasa.com To make linux audio more attractive, I am looking for developers to partner with me in building a "Just Works" device one can plug in the wall, and hear the latest and greatest of the Free Audio community. Ideally, the device would simply have an 'I Like It' button that would Cache whatever song is playing and direct the listener's preference profile toward similar songs. I would like to see this device be engineered using 'Free Engineering' principles, along the line of the Free Software community, being "funded" entirely by donated work efforts, all the way to the assembly line. This is an ambitious project, but I'm an ambitious kind of guy, and so our you when you let yourself be. I find it completely irrelevant what experience you have had in this field so far, as long as you feel a deep urge in yourself to be part of this project. Please contact me, right now! It doesn't matter if you don't know yet what exactly your participating what form it may take. Just contact me if you resonate with this idea and would be willing to donate a LOT of your time for this, for the reward of satisfaction, and probably some quite physical rewards as well; however these will be left to take care of themselves, which I trust they will. Contact me at: theman-AT-carlocapocasa.com I am also looking for developers who would like to fine-tune and even out current linux software synthesizers to make them completely rock-solid for live use, so anyone can use them to play a gig with 10'000 people without thinking once that there might be dropouts. Of course number of possible voices is limited by processing speed, however CPU cycles need to be managed in such a way that limitations in processing power are reported and can be dealt with off-stage. Most specifically, I am talking about ZynAddSubFX, and to some extent Om/Ingen. Another area that needs development power is transparency; ZynAddSubFX is a fantastic sounding synth, however its interface can be cumbersome for some purposes, specifically automation. Additionally, these sounds should be accessible in a standard way, without requiring but optionally enabling MIDI. The best way to accomplish these goals would be to create a ZynAddSubFX DSSI plugin with a complete redesign of the interface; in addition, a set of LADSPA plugins for use in modular synths would be excessively helpful. Again, it doesn't matter if you have development experience, it is plenty if you have the will and the dedication to invest your time and energy. I will work closely with you and your reward will be that YOU were the guy who made it possible for tens of thousands of people, heck, millions of people to enjoy the sound of the Free Software synthesizers played live and in realtime in the most advanced way possible. Contact me. Contact me at: theman-AT-carlocapocasa.com The company is not really a company in the conventional sense, just people working together on a common goal. There will be no central authority and no orders; just suggestions and mutual service. There will be no guaranteed rewards, however there is deep satisfaction that this project will be the only way for you to attain, you being the right person for this project. It will be your key to salvation if you will, your holy grail, your life's mantra. Devoting yourself fully to it you will open the possibility for "All the ways you haven't thought of yet" to come together and make it possible for you to continue living. And I'm not talking about just any living, I'm talking about living in TREMENDOUS WEALTH. Again, you will probably not receive your "rewards" directly in the form of a bribe, and you will certainly not be lead around by the nose with petty rewards. You will do what you do to accomplish your goals that satisfy you, and you will learn how to do that. Simultaneously, you will learn from me how to attract into your life whatever (material or not) you need to enjoy your life more, and how to open your channels for good to "happen to you". (Yes, money cars and women can "Happen To You", I will be more than happy to explain exactly how that works to you, all you need to do is ask.) So I'm looking for passionate software developers and engineers! Please contact me. Contact me at: theman-AT-carlocapocasa.com We will change how the world works. Money is a wonderful thing, if you don't let it dictate what you do and what you don't do. You can simply use it like you would use other shiny things, as a token of appreciation. You can also use it to encourage services where there would otherwise be ambivalence. Money is a good thing! And money definitely does not have to be a reason to do anything else than what YOU are passionate about; and this, as parts of the free software community, we will demonstrate to the world in undeniable clarity. Have any of you noticed how sleek and, in short, how amazingly good the Mozilla browser is? I mean three platforms, and this software quality, that is nothing short of a miracle. Linux Audio can be that way too! We just need to get a little more organized, and I will be more than happy to serve as a usability expert, since I'm a guy who uses the software professionally and I have the technical skills to communicate what needs to be changed and what most realistically can be changed (while still keep a "No Limits" attitude. Contact me at: theman-AT-carlocapocasa.com Join me! Help me create good free software AND free hardware. You don't need to know how, and I don't need to know how. Faith and action will take care of the rest. Whatever techniques you will need to accomplish these goals will come to you as soon as you have made a definitive decision to accomplish them. All you need do is decide that it WILL happen and never think back. The free hardware is so sexy you would hardly believe it. Think of it! We can be giving away "music boxes" that are constantly loaded with the latest in the free music community, according to the listener's preferences, which he can communicate with a big red button. Lit with a high-powered LED. Man this is so sexy I almost have to change my underwear after even thinking about this. Join me, guys! Contact me at: theman-AT-carlocapocasa.com Carlo
