[linux-audio-user] realtime not available

by Atte André Jensen

Hi I had realtime working just fine (debian/etch, 2.6.18-rt8), but now it doesn't. And i can't figure out why... When I start qjackctl I get this in messages: cannot use real-time scheduling (FIFO at priority 10) [for thread -1210070368, from thread -1210070368] (1: Operation not permitted) atte@ajstrup:~$ grep -v '#' /etc/security/limits.conf @audio - rtprio 99 @audio - memlock 500000 @audio - nice -10 atte@ajstrup:~$ grep atte /etc/group dialout:x:20:atte,emil,britt cdrom:x:24:atte,emil,britt floppy:x:25:atte,emil,britt audio:x:29:atte,emil,britt video:x:44:atte,emil,britt plugdev:x:46:atte,emil,britt atte:x:1000: atte@ajstrup:~$ sudo apt-get install libpam0g Reading package lists...

[linux-audio-user] intel core 2 duo and amd turion 64x2

by ljc＠internet.com.uy

hello list, i intend to buy a new laptop, and i'm undecided between two models of hp: dv6255us and dv6275us. both are very similar, but the 6275 has two pros: bigger L2 cache and 128Mb of dedicated video ram. but it has a intel core 2 duo, and my initial intention was buying an amd turion 64x2. any ideas how the core 2 duo compares to the turion 64x2? any experiences using these laptops with linux? the 6275 seems to be a bit better, but as i said, i was intending to go for the amd. should i go back to intel after all these years? here are the details of both models: http://www.pricegrabber.com/search_techspecs_full.php/masterid=32673075 http://www.pricegrabber.com/search_techspecs_full.php/masterid=32665203 thanks for any comments that would help me make up my mind, i'd like to decide this matter soon and i really don't know what to do. best, lj

[linux-audio-user] Question re QSynth/fluidsynth

by david

I noticed that you can set QSynth/fluidsynth to output to a file. Does this mean it outputs the sound to that file? If so, what format is the output in? How can I convert it to something else, if necessary? Thanks. -- David gnome(a)hawaii.rr.com authenticity, honesty, community

Well, personally, I don't think so. :-) Let me rephrase it to "extremely unreasonable" then. Hmm, this disussion is too vague.

Not really. > You write a song, > you get to charge people royalties to perform it. > Yes, in certain cases, like arranging concerts or playing music in a bar, if you use someone music whos copyrights are handled by organisations that handles such, you may be required to obey rules set up by those organisations. This is how it works in norway, but similar systems probably exists in other countries. But this situations is different, this is a guy doing his own interpretations of other peoples music, and gives it away for free. He is a private person doing non-commersial activity, and he is not breaking any copyrights. As I said, I don't know, but it sounds so very very wrong if this is illegal. And in the unlikely event that it actually is illegal in the country where the server is placed (the netherlands?), this is a good opportunity to perform some civil disobedience. If a law is wrong, its supposed to be broken.

[linux-audio-user] note: apps.linuxaudio.org

by Robin Gareus

There have been a few edits on our "deveopment"-wiki apps-devel.linuxaudio.org ! sorry for the confusion: http://apps.linuxaudio.org is the "real" site. http://apps-devel.linuxaudio.org/ is our *test server* that we use to experiment with PHP, plugins, designs, software updates, etc - it's actually a 1:1 mirror, but not intended for the public. - we ought to set up a jailed webserver behind openvpn for testing, but we're just not there yet :( robin

[linux-audio-user] live performance with rapper/vocalist

by Josh Lawrence

Hello list, (Please forgive me if this post rambles a little bit...) A very good friend of mine approached me about doing some rap music live with him. He is a lyricist with a drumming background, and does a fine job at expressing himself in that particular genre. I am a jazz piano player and, of course, linux user. :) I would like to try to do some live performances with him rapping and me providing groove-based jazz backgrounds (think acid jazz-type stuff, MMW, etc.). I think this would be a great opportunity to use linux in a live performance. Here are some off-the-cuff thoughts about how this would go down: The computer would be providing beats. There should be a set of beats preplanned, a "vocabulary" of stuff to pull from, but it must all be able to be changed on the fly. Seq24, maybe? My live keyboard would provide sounds for keys and bass synth, but the laptop should have a bass synth pulled up to do repeated patterns when my left hand gets tired; I'm thinking whysynth (the dssi plugin) for this job. It would be really nice if everything could sync to MIDI clock so that an arpeggio-type app could be used (I have no idea what would do this in linux). Hydrogen would fall into this picture somehow I'm sure, but it seems like it isn't appropriate for doing stuff on the fly. Would be *great* to use LASH to pull the whole "set" up at once without having to call up individual applications. What do you all think? Are any of you doing anything like this, and if so, how are you doing it? I really *don't* want to get into live coding just yet, I'm just not ready to dive into those waters. Still, I think this would be a really cool project - "improvisational rapping" if you will. Any thoughts, gripes, ideas, general thinking outside the box, and (most importantly) specific applications that you think would be appropriate would be very much appreciated. -- Josh Lawrence http://www.hardbop200.com

[linux-audio-user] real-time MIDI scripting?

by Larry Troxler

Hi. Is there any scripting language out there that can read and write Alsa MIDI? I want to do things like remapping, intelligent, dynamic, keyboard splitting, assigning certain notes to close-open applications, sending alternate notes to different MIDI channels, and things like that. pd of course is a possibility, but at the moment I'm having problems getting pd-extended to run in 64studio, and regardless, I'd like to explore the text-language route.

[linux-audio-user] Vintage Style Recording in Ardour?

by DCZX

Does anyone know what plugins/techniques could I use to record something in Ardour that sounds like it was recorded on 70's vintage tube/tape equipment? ____________________________________________________________________________________ The fish are biting.
