You should get sounds out of Zyn using it's inbuilt keyboard, even if your Yamaha one has some problems. Have a good look at alsamixer's controls on the CLI (konsole/terminal). Controls like "master" "pcm" "front", if you have them need to be unmuted and the sliders pushed up. The fact that your sounds are working on Ubuntu is a good start. It's worse when you have no sounds at all. > > I hope this gives you a clue. > I think its confusing. > > Kresten Which soundcard do you have? lspci will show you this. Just post the relevant bit for the soundcard. You say also that you recompiled the kernel. Have you still got another kernel you can try, and see if the sounds work ok with it? Just a question, but sometimes something can be missed when configuring a new kernel. Saying that though, you say that sound is working on ubuntu. Please make sure you do a "reply to mailing list" from your email client, or a "reply all" if you want to reply to me also, as there may be other folks that can help you with this problem. All the best. Nigel. btw. Would you post the output of lsmod | grep snd

[LAU] What Price Interoperability (OpenDAW, revisited)

by David Baron

A product release at the current Winter NAMM is Solid State Logic's Pro-Convert. Transport your DAW projects to and from most everything proprietary except (gulp) Sonar/Cakewalk. $700 smackeroos and you have it. Looking at their supported formats was informative: Steinberg has an XML format for Nuendo 3.x and Cubase SX3 and later Apple has XML for Final Cut Pro 4, 5.x, Logic 8, Soundtrack Pro 2. Vegas as text and XML formats. Samplitude has a text format. Besides no Cakewalk, NONE of the opensource DAWs and audio editors are supported. AAF and AAF/XML are definitively ignored. I need the $700 to pay my rent. We all need everyone to get together, merge all those XMLs and make things easier for everyone. There may even be some studios and individuals out there that would play a REASONABLE price for such software and not bother to compile and futz with it!

[LAU] Money

by thomas fisher

This story on the Wall Street Journal may be germain. It is about the Google philanthropy project and what it is they are attempting to do. A number of developers on this list have voiced in past postings of the need of financial support. I suspect that if a collective Linux Audio group were to approach google that funds might be available. http://online.wsj.com/public/article/SB120058125428197687-h1yUGpkjCq0_vVoL_… Please take time to check out the video. Hope this is of use. Tom

[LAU] Distortion with preamp

by Leslie P. Polzer

I have bought a used Audio Buddy to help me use my guitar and microphone with my box. The microphone XLR in works as expected, but as soon as I turn up the gain knob at the instrument in more than, say, 20-30%, the sound gets distorted with a crunch that would let some effects pedals appear pale in comparison. Is this to be expected? Leslie -- My personal blog: http://blog.viridian-project.de/

[LAU] FW: [piksel] Fwd: [estudiolivre] I believe in cinelerra

by Ivica Ico Bukvic

This looks like an opportunity to beef up audio side of things as well as foster development of another powerful foss multimedia software. See below for more info.

Why Cinelerra is the most powerfull free software for video editting we have nowadays. Although it has many resources and that it is far more advanced than any other Open Source video software, its development is very slow and has no sponsor. Its main developer, Heroine Warrior, do not mantain a SVN or a mailing list. The last official release was last july and there is no sign of a upcoming version of cinelerra. They usually publish a new release every six month or so but do it only for their own needs and do not talk with the community much. Few developers mantain a fork called "Community Version". All out of volunteer work they mantain a SV a mailing list and an online wiki. They also fix some bugs and add some features to the code. This desorganized development results in a mess. There is no official stable release and package for the distributions, and cinelerra is now known as very hard to install and unstable software (although it got really better last year). Also, first contact with cinelerra is usually disappointing because of a not well resolved interface and also because of big flaws it has on some funcionalities. With all that said, it happens that we have a software that is, at the same time, powerfull enough to do any kind of editing, but weak enough to have very basic issues of usability. And the feeling all advanced users have is: We are pretty close to have high standard software! To learn more about the mess, take a look at this page: http://cv.cinelerra.org/about.php Many of the actions described on this plan are already been done by many people, but in a rather heroic way. If this people got motivated, organized and _paid_, cinelerra would increase its quality dramatically in a short period of time. The Plan 1. Get the community together The community of developers today is very small and spread, and cinelerra has no road map. First thing to do is gather this people to discuss about the future of cinelerra, identify the main flaws and its solution, make a plan to organize the place and set up for new features. Cinelerra needs a project leader, an interface designer, and more people with defined roles that should be choosen on this meeting. Developers of other softwares are also welcome. Cinelerra is, so far, the only video free editing video editing software with professional approach, but it could share a lot of things with other software, such as effects, for example, that shoul be usable in any video software, just like we have LADSPA for audio. There is already a video effect standar called Frei0r that cinelerra does not support. 2. Diagnostics Cinelerra code is not very well documented, so few people have the idea of how tuff is to deal with it. Second step is to see what must be done so we can invite more people to colaborate with the code. Documentation, refactoring, etc. It also has to work on the API so other people can write plugins and effects. In other words, lots of work that are a pain in the ass but has to be done in order to advance properly. And passion has a limit. There must be people getting money to work on that. 3. Make a plan Based on the diagnostics and on researches with users and other video editing tools, define how cinelerra will look and act in a not so distant future. With that goal in mind, make a reasonable plan to make it happen. 3. Set up a core development team No secret here. Few people dedicated to make it happen, including an interface designer. 4. Bounties The core team can offer bounties for parts of the job they choose. This will attracat more developers to the community. 5. Attract contributors Mantain a nice looking website, a wiki, tools for easy translation of the interface and of the online documentation, etc. are goos strategies to attract people to contribute. Its also important to find people to package the software for different distributions. -- leogermani.pirex.com.br leogermani.estudiolivre.org ________________________________ Lista de Discussão do Estúdio Livre portal colaborativo -> http://www.estudiolivre.org/ sobre esta lista -> http://lists.riseup.net/www/info/estudiolivre -- Fabianne Balvedi GNU User #286985 http://fabs.estudiolivre.org "As contradições mais agudas da vida humana não foram feitas para serem solucionadas, mas vividas com plena ciência de seu carater paradoxal."

[LAU] Period Elongation NOW !

by lanas

Hello, Looking for a way to 'elongate' the period of MIDI events. Doctor, what should I do to please her ears ? Seriously, the problem is, Qsynth cannot play any MIDI note that is played by a percussive MIDI pad, in this case the Alesis Control Pad played with drum sticks. Here's the thing (cheap at some $250 brand new): http://www.alesis.com/product.php?id=103 It's as plain and simple as that. Can anyone verify it ? Start up Qsynth, load the Chromium sound font, pick a piano sound, connect a MIDI percussive instrument, and try to play 10 consecutive, clear notes. No way. Try then with a percussive soundfont. A drum set. Now, do the same with Hydrogen and the same MIDI pad. Works nicely. Velocity works also nicely. Now make it take into account MIDI note offs (it's in the Preferences, the default being to ignore them). You'll see that although most notes play OK, some are clipped. Try also with WhySynth. Some patches work OK, some don't. When they work, they even work with drum stick rebounds, as with Hydrogen. From Kmidimon, the Alesis Control Pad MIDI notes, when hit with drum sticks, last typically 1 unit of time (whatever unit that is) eg.: Time Event Data1 Data2 89985 Note on 63 0 89984 Note on 63 55 Whereas the shortest note I can do on an Axiom 25 keyboard looks like: Time Event Data1 Data2 41067 Note on 89 00 41051 Note on 89 94 That's a whole 16 units of whatever time. Same with the Axiom's pads: they last a long time and thus, interact OK with Qsynth. My theory about Qsynth (Fluidsynth...) is that the MIDI notes sent by the MIDI percussion instrument are too short for it to pick them up. Could that be ? It'd be nice to play all those available percussive soundfonts using a MIDI percussion controller. Wprks all right with Hydrogen, but not with Qsynth. Should Alesis make their Control Pad send longer MIDI notes ? Or have a programmable parameter for each note ? I don't know. Hydrogen works, but not Qsynth. But then, can there be a default note length ? I would be glad to set some default note length. I could even take the time to set notes lengths according to soundfonts and load them with the instruments... as long as there's a filter that could do that. So, is there a MIDI filter out there that would enable something like this ? To make (all or specific) MIDI notes last longer ? Thanks for reading, and do not hesitate to throw suggestions. Jam, no spam, Al
