Hi all, I recently switched to FC2 with the CCRMA 2.6.8 kernel. I was wondering if there is a way to tune pdflush in the 2.6 kernel like you could bdflush in the 2.4 kernel? I have seen advice on this list to set bdflush by adding *"echo* "10 64 0 0 2000 15000 90 5 0" > /proc/sys/vm/*bdflush" to the rc.local file, thus causing bdflush to write smaller chunks more often to disk instead of waiting for the "dirty buffer" to accumulate alot of stuff to write to disk all at once, possibly causing dropouts. Is there a way to do this with pdflush or is it even necessary with the 2.6 kernel? Thanks in advance. Rick B *

Greetings: Thanks, Marcus, I hope it's helpful. I've corrected some errors already, added some URLs to the plugins used in the tutorial, and a fresh version is now on-line. :) Best regards, dp marcus wrote: >Terrific work on this tutorial, which will help me and others do musical >things we never thought possible on a shoestring budget. > >Marcus Planet > >On Thursday 07 October 2004 02:43 pm, Dave Phillips wrote: > > >>Greetings: >> >> I now have direct ftp access to the Quick Toots site and have updated >>the VST/i tutorial here: >> >> http://www.djcj.org/LAU/quicktoots/toots/vst-plugins/ >> >> Enjoy, and please send corrections and suggestions directly to me. >> >>Best regards, >> >>dp >> >>Timo Sivula wrote: >> >> >>>Hi, >>> >>>I have put quite a lot of time on trying to make vstserver and jack_vst >>>to work on my planet CCRMA box to no avail.

[linux-audio-user] Linux Audio and Podcasting

by Jan Weil

I've been contacted by Ludo Magnocavallo who's trying to call the attention of Linux Audio users to Podcasting. If you haven't heard anything about Podcasting, as it was the case with me, you might be interested in the links I collected: <http://linuxaudioblog.jawebada.de/misc/linux-audio-and-podcasting.html>

[linux-audio-user] My experiences

by Geoff Beasley

Well, my studio has never been such an exciting place as it has been this last week. The reason is all those great developers on this and other groups who have been developing and evolving this most brilliant audio solution. I am currently running TAP reverbED, JACK Rack using G2Reverb and Freeverb, Ardour, Qjackctl, Jamin and Rezound all on Planet CCRMA RH9. This I call my Linfx machine incorporated into my system of 3 other standalone Windoze machines. Using a C-Port as an interface (I have 3), I've integrated the rev's into my send/return network on the desk and use Ardour to mix to, then Jamin to master. It runs all day, without any x-runs ( 512 buffer size) and my lust factor is beginning to grow daily. Your efforts as a community have begun to pay off; if you setup a machine properly on the hardware level first, then follow the elegant and clear explanations provided by Nando (you rule guy!) even a newbie like me can can get this up and running to this level of totally stable functionality....for real ! I can't tell you how fantastic it is to be finally using Linux with these outstanding apps.... and it's looking so good for the future. My sincere congratulations to Paul,Jan,Tom,Jack,Nando,Rui,Dave,Steve,Bob,all the LADSPA dev people and of coarse Linus ! And a very special thanks to Dave Phillips 'cause without him I may never have heard of any of you ! Very well done. Geoff.

If no window is showing up you've got a problem. Otherwise- Jack connections: it won't connect to jack until you select Effector->Play Presets: you create your own and save them using Preset->Save New Preset Tool Bar: don't need it Configuration window: Use View->Show Whatever_you_need_to_see I'm running it on a Gentoo box. -Reuben

I wouldnt know. I just built 2.6.9-rc3-mm2-VP-S9 but the first thing I get when I boot is a Aieee Kernel message. I cant figure out where because its on that initial screen where the font is giant. And of course syslogd has not started yet. Any ideas why? Thanks for the help! -thewade

[linux-audio-user] Difference between T and S in Voluntary Preempt patches suffix

by thewade

I am just about to build voluntary-preempt-2.6.9-rc3-mm2-S9, but now I see in Ingo\'s folder some voluntary-preempt-2.6.9-rc3-mm2-T0 and T1 patches: what is the difference between the two? Thanks! -thewade
