[linux-audio-dev] Fw: [linux-audio-user] brasil + linux

by Florian Schmidt

Begin forwarded message: Date: Fri, 26 Nov 2004 19:48:10 -0200 From: "criscabello ." <criscabello(a)gmail.com> To: linux-audio-user(a)music.columbia.edu, articuladores(a)arca.ime.usp.br Subject: [linux-audio-user] brasil + linux hi all!! my name is criscabello and i´m from brasil. please excuse my poor english. at first, i'd like to thank all of you linux audio developers who made it possible for us to work with free plataforms. all of us, brazilians, are very pleased with the result of all your work. let me explain. i work in a government project called "pontos de cultura" (points of culture), and it is based in the distribuition of media stations with free software to some places who are in a state of digital, or social, exclusion at this time (but not much longer, we hope). this project has a national scope, and in the beggining of 2005 will be distribute more than a hundred (100) media kits, with projections of distributing another thousand (1000) in the next two years! last saturday our group had a meeting with our minister of culture, gilberto gil, to showcase some softwares for media production (like ardour, audacity, hydrogen, jack, alsa driver, cinerrela, kino, etc...), and he was totaly convinced about the possibilities of our free software media production kit. He also understood the power of collaboration based work and open source development - this article from wired magazine (http://www.wired.com/wired/archive/12.11/linux.html) says more about the minister. oficialy, gil represents our nation, and his opinion represent all Brazilian's voices! at the end of our meeting, we recorded one of his songs using ardour, gil is a popular singer in brazil (and the world) and this was his first recording using free software. during the session the only thing in my mind was: thank you so much paul davis and all the developer communities! you all can listen to the song (and sample and remix it if you like, it is distributed under a creative commons license) from here: in ogg format: http://banto.hipatia.info/maquina-de-ritmo.ogg in mp3 format: http://www.pirex.com.br/pirexmp3/maquina-de-ritmo.mp3 this e-mail is to tell everyone that this is just the beginning, we have much work to do together (can you imagine the demands from all of these people working with our free platform?). and i'm so glad for this momment. thank you so much. criscabello ps. please foward this message for the developments lists.

Re: [linux-audio-user] Re: [linux-audio-dev] RME is no more

Not for me. :) anyway it seems there a *lot* of linux audio users that bought RME because of alsa support. How about doing a list where everyone can submit his name and type of RME card so that we can see how big and attractive the market currently is? Marek

Well. Here is an official source that claims that control change 120 is in MIDI 1.0 (1995 revision). It is not the whole MIDI 1.0 spec, only a summary. http://www.midi.org/about-midi/table1.shtml Channel Mode Messages (See also Control Change, above) ------------------------------------------------------------------------- 1011nnnn 0ccccccc Channel Mode Messages. 0vvvvvvv This the same code as the Control Change (above), but implements Mode control and special message by using reserved controller numbers 120-127. The commands are: All Sound Off. When All Sound Off is received all oscillators will turn off, and their volume envelopes are set to zero as soon as possible. c = 120, v = 0: All Sound Off [...] The book "MIDI programmer's handbook", (C) 1989 by DeFuria & Scacciaferro, does not mention this controller. I guess that ancient MIDI instruments manufactured before the 1995 revision can't be blamed if they aren't fully compliant. Regards, Pedro

[linux-audio-dev] New releases

by Fons Adriaensen

Hello LAD, New releases of Aeolus and JAAA are available at the usual place : <users.skynet.be/solaris/linuxaudio>. >From the Aeolus-0.3.1 README : * Added 'instability'. Each pipe is individually phase modulated in order to emulate the random fluctuations in a real one. This provides for a much more natural sound, in particular for long sustained notes. CPU load has gone up a bit, but not too much. * New reverb. Comments invited. * Added stereo position slider. Internally Aeolus uses a full 3-D sound format (which you can use with the -B, -C 4 or -C 8 options). The stereo output is derived from a 'virtual stereo microphone' placed in the 3-D sound field. The apparent position can be set anywhere between 'back' and 'front'. * Divisions II and III can now be put at the back. * Wavetables can now be saved to disk. They will be used when Aeolus is later started with the same sample frequency and tuning, giving 'immediate satisfaction'. * New option -W <directory> to select the wavetables loaded on start. * New default colors, a bit warmer than before. * Added -name <name> option, this permits multiple instances when running under JACK. * New 32" stop. In fact just the Trombone 16 scaled down by one octave and tweaked a bit, but quite spectacular if your speakers can handle it. There's also a new demo file, Xmas.ogg (I know it's a bit early :-). For JAAA-0.1.2 : * Added -name <name> option, this permits multiple instances when running under JACK. Both apps need an update of clxclient.so, version 1.0.1. Enjoy ! -- Fons

[linux-audio-dev] Rosegarden: All Notes OFF

by Jens M Andreasen

Hi! According to my oldish midi-spec, controller (decimal) 120 is undefined, so I was somewhat confused at first when I got it from Rosegarden. A bit of digging shows that it belongs to the (newish?) GS-spec, and means All-Sound-Off (as in 'killall -9') It is a bit ironical that there is a DX7-plugin for Rosegarden, but the real-McCoy will leave you hanging with notes forever ... no? mvh // Jens M Andreasen PS: There is an Mx41beta.zip with alsa and jack waiting for fearless beta-testers. Do not hesitate, call now! DS

[linux-audio-dev] impulse convolution LADSPA plugin

by Stefan Turner

Hi list, This is my first post, apologies if it's not on topic or obvious, but I was wondering if anyone is aware of a LADSPA plugin for impulse convolution. The only thing I have found is Steve Harris's impulse convolver, which is intended for 'fairly short' impulses and they need to be compiled in anyway. If there is nothing out there, I will have a go at this: just wanted to check first. Thanks Stefan Turner ___________________________________________________________ Moving house?

And I don't have a problem with a plugin producing no "pluginnish output" when it's launched, using the default values, but... Even though they're merely hints, the freeverb init-settings (yeah okay, they're not init-settings, but "hints") really aren't nice to the system, and I don't like that. /Mathias

[linux-audio-dev] Re: [Alsa-devel] Firewire Audio Card Support

by Ramsey Tantawi

Y'all aren't the only ones thinking there's an opportunity in the firewire audio breakout box market: http://www.appleinsider.com/article.php?id=756 IF the reports are true--and Appleinsider has a pretty good track record--this is a pretty good affirmation of opportunity in this market. Or, at least of apple's attempt to own the market by acccepting a much lower profit margin. I would imagine that the more advanced version mentioned--if actually true--would sport more analog inputs.

[linux-audio-dev] muse and /dev/rtc

by Uwe Koloska

Hello, now that my audio inteerface is working, I can try the wealth of audio applications. Starting the SuSE supplied muse (0.7.0) it refuses to start cause it cannot use /dev/rtc. Since I used the audio group also for providing the realtime capabilities, I changed the group and mode of /dev/rtc to crw-rw---- 1 root audio But then it gives the following error message: cannot set tick on /dev/rtc: Unpassender IOCTL (I/O-Control) für das Gerät precise timer not available What is missing? Do I have to update the provided muse to a newer version? Uwe

[linux-audio-dev] Freeverb and default control parameters

by Mathias Lundgren

Hi! I've been trying to implement LADSPA send effects in my latest playtoy. I've had some problems with freeverb though. It simple doesn't produce any output (execution seems to be veeery demanding) until I specifically set some of the parameters to non-default values. I thought the default port parameters would take care of this, initializing the plugin with sane values to avoid things like these, but perhaps I'm doing something wrong... Has anyone else noticed anything similar with freeverb? /Mathias
