Hi everyone! OK, I solved my "plugindir/libasound_module_pcm_jack.so: no such file or directory" problem. It was a bug in alsa-lib 1.0.14, which was obviously fixed in 1.0.14a. But now I try to use my jack plugin and get a smple format problem. I start jackd like this: jackd -R -d alsa -d hw:1,0 -r 48000 -p 128 -H -M -z shaped then I start aplay (both with 44100/2ch/16bin and 48000/2ch/16bit) and get: aplay: set_params:900: Sample format non available What's wrong? I have a delta 1010LT, so a lot more channels, and jack internally uses 32bit floats, but my jack-plugin is configured for stereo and the pcm.!default wraps around it like: pcm.!default { type plug slave { pcm "jack" } } So there should be some conversions. Any ideas on this? Please?

request for filmed interview for the Digital Tipping Point documentary

by Christian Einfeldt

hi, I am producing a documentary movie called the Digital Tipping Point about how Free Open Source Software (FOSS) is changing global culture. I have been mostly lurking on this list for a while, because we are using all FOSS tools for our project. I am wondering if there is anyone on this list who is making active use of FOSS audio tools in the San Francisco Bay Area. If so, I would like to interview that person on film for the DTP project. We are building the DTP out of fully forkable footage here on the Internet Archive. Link below. (Forkable here means that you can both copy the footage and create a derivative work). Our idea is that we want to produce a movie-in-a-box for people with really low end systems who would like to get decent interview footage to include in their own little movies about why FOSS is cool, and how it is going to change their lives. We have filmed many dignitaries such as Christian Ude (the Mayor of Munich), Hermann-Josef Pelgrim (the Mayor of Schwaebisch Hall), Gilberto Gil (the Culture Minister of Brazil), and Luiz Millan Vazquez de Miguel, (the Extremaduran Minister of Science, Education). The theme of our film is that Free Open Source Software (FOSS) will help foster an explosion of literacy and creativity globally. Our film is the first feature length documentary to be built on-line out of fully forkable footage released under a Creative Commons Attribute-ShareAlike license on the Internet Archive. We have 55 hours so far loaded onto the Internet Archive's Digital Tipping Point Video Collection. You can see our raw video here: http://www.archive.org/details.php?identifier=digitaltippingpoint That footage is raw footage, and will need to be re-rendered before it is used in any final project. It is also much more poorly lighted than you are used to, and the audio is also only on one channel, to reduce overhead. Also, frankly we are simple end users who are hoping to prove that yes, GNU Linux is simple enough that even a knucklehead like me can make a full-length movie using it! Plus, one of our video editors is 80 years old. Talk about your grandpa using FOSS ! We have been to 5 nations and 3 continents on a shoe string budget, and so we didn't have the resources to drag lighting equipment along. We shot everything with a Sony PD-170, which is a decent pro-sumer piece of equipment. Our keyword search index page is located below. It is the place to go to find specific persons or themes for our footage. The Internet Archive is currently changing its search software, and so the index might not be operational again until Monday, December 10, 2007. Here is the index page nonetheless: http:// tinyurl.com/yluwoc <http://tinyurl.com/yluwoc> The theme of our film is that the US is falling behind in certain technological areas due to its dependence on Microsoft and other proprietary code in areas where FOSS is ready for production on the desktop and elsewhere. We are going to contrast our experiences in seeing the status of FOSS desktop development we found outside the US with our experiences here in the US in trying to migrate just one public middle school to FOSS. Thank you either way for considering our request. -- Christian Einfeldt, Producer, The Digital Tipping Point

hardware - buttons and knobs?

by Josh Lawrence

Something mentioned in the hardware synths thread prompted me to ask this question... So how does one go about adding buttons/knobs/switches that do specific things to a standard computer? My best example of this is the Muse Receptor - it is a standard computer, yet it has knobs that do various tasks. I realize there is a hardware and software answer to this question, but I'm more interested in the hardware part. In other words: 1)Where can I buy a knob? 2)Where do I plug it in? Finally, I also realize you can buy MIDI knob boxes; that's not what I'm talking about here. -- Josh Lawrence http://www.hardbop200.com

Still unresolveable problems with alsa-plugins

by Julien Claassen

Hi everyone! Sorry for ross-posting. But I need help urgently! so here's my problem. I'm running alsa 1.0.14 (driver/lib/plugins/utils). But with every app I tried, I get the following error: ALSA lib pcm.c:2105:(snd_pcm_open_conf) Cannot open shared library plugindir/libasound_module_pcm_jack.so aplay: main:545: audio open error: No such file or directory I just built alsa-lib, plugin and util again. I gave: --with-plugindir=/usr/lib/alsa-lib to both lib and plugins. Still I get the error with aplay and yatm. Here's my .asoundrc: pcm.jack { type jack slave { card 1 } playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_3 1 alsa_pcm:capture_4 } } ctl.mixer1 { type hw card 1 } pcm.!default { type plug slave { pcm "jack" } } ------------- Can anyone please help me?

timidity and jack issues

by naysayer

hi all. just wondering if there is anyone out there using timidity(2.13.2-r6) and jack successfully. i seem to be have some issues getting it to connect. firstly, i am using gentoo with a hdsp multiface. while i can get timidity to run quite nicely using the midi protocol, the audio seems to be a bit weird. running timidity without jack.... $ timidity -iA -B2,8 -Os -EFreverb=0 it is all fine and perfectly usable. ----------------------------------------------------------- with jackd 0.103.0 running $ jackd -R -dalsa -dhw:0,0 -r44100 -p64 -n2 and timidity as $ timidity -iA -B2,8 -Oj -EFreverb=0 JACK tmpdir identified as [/var/run/jack] TiMidity starting in ALSA server mode Opening sequencer port: 129:0 129:1 129:2 129:3 i can see the midi input in my qjackctl patchbay and this is usable. the problem is that i can hear the audio from timidity and is usable but i have no outputs in my qjackctl audio patchbay. also, i cannot see timidity ports showing up in the ardour buses. this seems weird that i can hear the timidity audio using jack but i cannot see or use output ports in qjackctl.

Decent soundfonts

by Simon Williams

Ok, so I have the worst speakers in the world at the moment, which probably doesn't help, but I also think I'm lacking a decent soundfont. At the moment I'm using FluidR3GM. I've heard people say that it's pretty good, but that's not the experience I have (or have with any soundfont I've tried so far TBH). Firstly, in the opinion of people who actually know what they are talking about and has decent hardware (i.e. anybody on this list except me), how does fluidR3 compare to: 1. soundfonts you can buy 2. soundfonts built into mid-range keyboards The biggest issue I have with it is that it seems to have been made from samples of instruments not more than one octave above or below middle C. If I go much lower then it's far too 'muddy'- if that's right word- essentially it vibrates too much, instead of giving a clean sound. If I go much higher then it's too 'sharp'- the sound happens very suddenly, with a 'twang', and doesn't sustain for very long. A lot of the instruments also seem to have a background noise which I can't really describe. Also, most of them 'twang' too easily when you hit the keys harder. Anyone know where I can get better soundfonts? I've downloaded all the ones I can unpack from hammersound, and some are better, but I can't find that many. I'm mainly after a variety of piano type sounds (anything from grand to totally electronic) and pad/strings type sounds. Thanks Simon

But now I always get: ALSA lib pcm.c:2105:(snd_pcm_open_conf) Cannot open shared library plugindir/libasound_module_pcm_jack.so This occurs in a few variants depending on the app I use.
