I'm preparing a seminar that will take place tomorrow (4 May),
it will involve live mixing of surround sound using Ardour.
While setting up the PC to be used, two problems occured.
The first one is solved, but its cause remains misterious.
A some point it appeared that the sound card (HDSP-MADI,
used every day since years) had decided to meet its creator.
Every program trying to access it - from jackd to aplay -L
not only blocked, but turned out to be impossible to kill.
Replaced the card - same result. It turned out to be a
corrupt /var/lib/alsa/asound.state. The systemd service
doing the 'alsactl restore' while booting choked on it,
blocked, and this apperently blocked all others trying
to use the card later. What I don't understand is how alsactl
exactly failed, and why these processes seemed to be immune
to a 'kill -9'.
The second one is an Ardour2 session that worked perfectly
on another similar PC, but becomes completely unresponsive
on the one to be used. It has four mono tracks and three
10-channel ones, and little else. DSP load is not the problem,
it's less than 15%. Things look like it's the graphics. When
Ardour's playhead reaches the right end of the editor window,
it takes something like 5 seconds for the editor display to
update - everything seems to freeze during that time but audio
is not interrupted. Same when trying to scroll or change the
zoom factor. Video card is Nvidia GeForce 7300, indeed quite
old, but the same PC does full-screen HD youtube videos without
problem. Video driver is nouveau as nv seems to be no longer
supported by Archlinux. I'm pretty sure this system didn't have
such problems when it was using nv. OTOH nouveau works very well
on other systems... I could try and install the proprietary
Nvidia driver, but with just some hours to go I'd rather not
take any risks...
Any hints ?

Hello list,
libsndfile-info shows various useful information like the one at the end of this mail.
I have Sonatina Symphonic Orchestra waves here (violins 1) and a one note wave includes "Midi Note", "Loop Count" and "Cue Start : 92078 End : 223977", which is the actual loop start/end
Is this custom data or does it follow a standard?
And no matter what, how do I write that into my own wave files?
I would prefer command line tools. But programming interfaces are fine as well.
Greetings,
Nils

Hiho,
this Wednesday there is a Creative Music Coding lab meeting at STEIM:
"The CMC lab is an autonomous zone to try out sonic experiments as a
group. And an opportunity to leverage the expertise of the group in
realizing new artistic tools and processes through the medium of code.
Many of the founding members of the group are indeed experts in their
favorite languages, but we come from all technical levels of
proficiency and enjoy helping one-another out."

DATE: Wednesday, 24 APRIL 2013
TIME: 19:00
ENTRY: FREE
LOCATION: STEIM Concert Space, Utrechtsedwarsstraat 134 Amsterdam, the
Netherlands
Sincerely,

Hi,
I'm happy to share with you a new beta release of io GNU/Linux, a complete
multimedia workstation based on Debian SID and built with the great Debian-
Live tools.
It includes programs for most uses, with Enlightenment e17+ecomorph as window
manager, Jack2 and Ladish, etc...
This build doesn't include documentation / getting started... Will be part of
a future iso.
Feedbacks welcome, enjoy :)

Laborejo 0.7 is released.
Together with a new website design http://www.laborejo.org comes a new release of the Music Notation Workshop.
Besides the usual fixes and small enhancements please focus your attention on the following new features:
-Non Session Manager support. Start Laborejo through the NSM Gui and it will be under session management
-Numpad Palette and corresponding shortcuts. A gui widget shows you what musical objects your numpad will insert.
You can change the palette through the menu or by switching through with numpad-plus and numpad-minus.
-A moving playback cursor, showing you which part of Bachs "Kunst der Fuge" you currently don't understand
Laborejo -Music Notation Workshop- is a graphical user interface for Lilypond, a MIDI creator and finally a tool collection to inspire and help you compose. You get beautifully engraved notation through Lilypond and nice ways to control the playback without ever leaving a notation-based environment.

They share the same API.
You're making an error with your link step.
