Hello,
I have two low-latency questions:
- How do 2.4.20 (LL+preempty) and 2.5.68 compare? Are there any patches
for improving latency on 2.5.68?
- NVidia drivers, being closed source, might contain long codepaths which
are not patches by the LL patches. Does anybody have bad experiences with
NVidia cards that confirm this, or do they seem to work correctly?
Thanks.
Maarten
I have a Nvidia motherboard with an embedded nvidia graphics chip and ethernet card and soundcard. It's all fairly closed source. Excepting the soundcard, which I haven't gotten to work (I use an ice1712 and an sb512), I can fairly reliably run jack at -p 512.

Hello list,
A new LADSPA plugin, "moogvcf-1.1", has just been uploaded to
<http://alsamodular.sourceforge.net>.
It contains three versions of the 24 dB/oct lowpass Moog VCF, in which
I try to emulate some of the non-linear behaviour of the original.
Enjoy !

What does it mean when it says "zombified -- exiting from JACK". Why
exactly is it becoming a zomby or what does it mean and, how do I
reconnect if it does that? It seems to do it intermittently without any
clue why it does it.
Thanks
Hi.
New release ...
Important news in v0.0012
-------------------------
* Added 1 Midi Inputs and 4 Midi Outputs. (Now two INs and six OUTs)
* Added 2 small utilities for convert Combis and Banks to this new version.
* Added new command line functions
* Now SountFontCombi recognizes program change. (1-44)
* Solved bug in bank window, now display the names correctly when you load a
new bank.(sorry for that).
* Solved command line segfault when load confi
* Solved "many" other minor bugs.
And of course new bugs added :-).
Bad News
* Due the changes made in v.0012 you need to REWRITE your configuration.

1. A short summary of changes
User-friendliness of 'jack_auto' and 'resample' audio
objects has been improved. Compile-time support added for
both JACK -0.50 and 0.60-. Python-only implementation of ECI
is now selected by default. Work-around included for a bug in
ALSA -0.9.1 that broke xrun handling for record and playback.
Lots of small bugs have been fixed in the build process.
The SIGFPE bug that occured on FreeBSD systems is now
fixed, as is the non-aligned access problem on Alphas.

2. What is ecasound?
Ecasound is a software package designed for multitrack audio
processing. It can be used for simple tasks like audio playback,
recording and format conversions, as well as for multitrack effect
processing, mixing, recording and signal recycling. Ecasound supports
a wide range of audio inputs, outputs and effect algorithms.
Effects and audio objects can be combined in various ways, and their
parameters can be controlled by operator objects like oscillators
and MIDI-CCs. A versatile console mode user-interface is included
in the package.
Ecasound is licensed under the GPL. The Ecasound Control Interface
(ECI) is licensed under the LGPL.

Audio software for Linux!
Hi everyone,
the organisers of linux.conf.au have agreed to provide a venue for a
Linux Audio Mini-Conference, in the lead-up to LCA2004 in Adelaide,
South Australia. It's in January 2004, which should provide enough time
for planning your travel down under :)
I've drafted up a Call for Participation and other info at:
http://www.metadecks.org/events/lca2004/
I'd like to encourage as many of you as possible to come along. It
will be held in the days before linux.conf.au, hence you'll get a full
Linux conference afterwards and a chance to talk to the kernel folk
and other developers and users.
January is mid-summer in Australia, and linux.conf.au has a history of
fine weather and great beaches. In 2004 the conference will be held in
Adelaide, a city well regarded for its churches, wineries and the Coopers
brewery -- quite possibly the finest beers in the country!
I hope to see you there :)
Conrad.
Just looking at what maya uses to do it's auto graph layout:
http://www.tomsawyer.com/glt/
I think we discussed this before, but are there any opensource solutions for
this? Might be an interesting project, although I can imagine it getting very
heavy...
Would be nice for our modulars though. The graph on the left of the second
diagram is very familiar to me from using SSM anyway ;)

Hello list,
the first LAD conference is just over, but there is already the next
event at the horizon which needs to be planned for timely. I am talking
about the next LinuxTag (http://www.linuxtag.org - though it seems they
have problems with their NS entry right now..), Europe's largest
exhibition on all kinds of topics dealing with our favourite OS. It
takes place from July 10th - 13th, 2003, and again - surprise, surprise
:-) - in Karlsruhe.
As in the past years, open-source projects are given a chance to present
their work there (without having to pay any booth fees), and we did this
during the last 2 years (and even quite successfully, I might add).
I had a short E-mail talk with Martin 'Joey' Schulze, who is again
responsible for allotting the space for the open-source booths, and I
think we have a good chance of getting one again.
The idea of this booth would be to present the current LAD developments
to the masses. That is e.g sample editing, recording, MIDI sequencing,
score editing, soft synthesizing and soon on. If possible, I'd also very
much like to have some ALSA developers there again as..uhm.."technical
consultants" :-).
It's 4 days of work, but quite interesting, you learn a lot, and I think
most of you who were there the last 2 years somewhat enjoyed the show
:-).
Of course, what is required now is - you. The last 2 years we had about
6 - 10 people who ran the booth which gives everyone a chance to take a
break after 3 hours of constant demo'ing :-). Anyone who is willing to
devote some 4 - 5 days of his time to this project, please let me know.
If we get together enough personnel, there is a good chance for this
booth becoming reality once more.
Thanks for reading,
Frank
