Hi list, Since update to Debian 6.0.1, everything from the stable repos, the usb midi kbd don't work anymore. Have search the web and here, but can't find anything. It seems that the kbd is seen by the machine, but not in QJack. Have tried with and without the midisport-firmware and it's the same. dmesg says it has a problem with snd_usb_audio, but my limit is just here, before the modules and kernel stuff... Any help really appreciate ! some console outputs : f@f:~$ dmesg | grep usb .....

Question about rt kernel in Ubuntu

by Giorgio - Audiophilo

Hi all, since Ubuntu 10.10 the rt kernel it's not in the repos. Anyway it appears you can still work in rt mode. Does anybody know what happened and eventually what's the difference between the rt kernel and the one provided in this distro? I'm a bit confused about this. Cheers -- Giorgio Baù *Sound engineer* T.Rex Studio www.trexstudio.com

moz major releases...

I posted the first 'recommendation' regarding to a member of the band Sky, who was member of the Academy of St Martin in the Fields. I don't know your 'recommendation', but IMO the German Rundfunk is one of the best schools for audio engineering on this planet :), so I suspect at least regarding to the engineering, this recording could be good. Well, I don't like Lenny as a director for music or as a composer just my taste), but anyway, he's a gifted guy, especially a gifted businessman :( and teacher for music :). Unfortunately his very good introductions to music aren't played very often by the German Rundfunk :(. OT: OTOH the German Rundfunk is wasting money of GEZ-mafia 'customers' by using the most expensive microphones even to record newsreaders and even while they already used Neumann for this, they additionally bought Brauner's most expensive mic for this usage. I'm not a 'customer' of the GEZ-mafia anymore. But I'm still an enemy of the Landesrundfunkanstalt, regarding to other very German issues. Btw. the German Rundfunk cancel most, perhaps all airplay of avant-garde music etc., but GEZ-mafia 'customers' are forced to pay for heavy rotation chart mainstream. 10 times a day the same Lady Gaga song etc..

I'm using Debian testing + a little bit of Debian stable, but build the 2.6.39 myself by using the config of a self build 2.6.33.9-rt31. Members of this list explained the reason why the default Debian kernel isn't PREEMPT-rt-emulating. If needed I can send you a script to build the kernel.

OpenOctaveMIDI 2 stable

by rosea grammostola

Hi, There was that announcement of 'We're just putting the finishing touches to OOM2, and will release shortly, as a tarball for general use. http://linuxmusicians.com/viewtopic.php?f=24&t=7043 But then the only response on questions about when the release will really happens they stay rather vague with answers like 'soon' or 'join IRC we might able to help you with that'. Does anyone uses oomidi 2 and / or can tell us what to expect really when it comes to an stable release or not and if yes, when? Thanks in advance, \r

I didn't make music until now using this kernel. Yes, I wish to "emulate" the PREEMPT_RT, since common PREEMPT only kernels never did, what I needed. What do I need to set? $ cat config-2.6.39.1 | grep PREEMPT CONFIG_TREE_PREEMPT_RCU=y CONFIG_PREEMPT_RCU=y CONFIG_PREEMPT_NOTIFIERS=y # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set CONFIG_PREEMPT=y IIUC this is correct?!

[OT] Free train ride from Hamm/Oberhausen to Amsterdam and back 62-28

by Julien Claassen

Hello Everyone! This sunday I'm going to Amsterdam and I have a free companion. So anyone interested? Leaving Hamm at 9:30, Oberhausen at 11:30 and on the way back Amsterdam at 14:30. The first two days I'll meet with a friend, but the last day, he'll be going early. So one might do something together. I've seen acceptable youth hostels near the central station, musems and everything else ne might want to see, for about 23 EUR per night. Warm regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de
