i would like to know if somebody has already thought about a (unified)
way to save or export the settings of ladspa plugins (or vst,lv2..)
I'm familiar with the idea of LASH, but i want to share plugin settings
between different sessions. A typical use case:
After recording songs with my drumset, the gate-plugin applied to
basedrum and snare has most times (nearly) the same setting.
At the moment this is a quite painful task: Ardour is able to save the
settings, but you can't export these or exchange them between other
In addition, ardour's ladspa plugin dialog can just save the settings,
changing an already saved settings is not possible. This results in a
heap of saved settings and old revisions..
It would be great to export these settings, it could be implemented as a
feature in applications like ardour2 ,jackrack or hydrogen.
After exporting the setting to a plain text file (or xml), sharing the
file with other people or between your computer would be no problem.
What are your thoughts on this? What are the disadvantages?
lwn.net has a very interesting interview with thomas gleixner and ingo
molnar about the future of the realtime preeemption tree.
this is a free link to content that is normally subscribers only:
i hope it's ok to post such a link in a public place.
the whole lwn issue will become freely available in a week or so. lwn is
a great resource and interesting reading, and if you've got a few

Liwoli 2009 hacklab for art and open source
23 - 26 April 2009
Art University Linz
Liwoli 2009 is a three day long Hacklab and an open invitation to
everyone who would like to participate in an active process of learning,
producing and sharing ideas around the areas of Free/Libre Open Source
Software (FLOSS) and DIY practices in digital art and culture.
FLOSS developers, software artists such as the collective GOTO10,
activists from HAIP (Hack Act Interact Progress) and many others form
the basis for the event and will share their knowledge in the form of workshops,
presentations, installations and performances.
For the event we are calling for contributions (presentations, workshops
and performances) around the FLOSS themes. This invitation is not only
for those who are interested in “Do It Yourself” and how it interrelates
with the current creative production practices, the invitation is also
directed to those who are interested in the cultural importance of
Submissions Please send submissions before the 25.03.2009 to

A quick update on LAC2009
The paper review has ended, and 24 papers have
been accepted - this will require some squeezing
to fit into a schedule. There are three major
workshops planned as well, LASH, Netjack and
CLAM, and possibly others.
The music for the concerts has been selected.
There will be two, on thursday 16 and saturday 18,
at the orchestra rehearsal room of the auditorium
The only part that remains hanging in the air is
the Linux Sound Night (planned friday 17) and that
is why people who have proposed to play there have
not had a definitive response up to now.
The problem is finding the right space. In the
center of Parma you need something that's soundproof
or you will get the 'vigili' at your door within a
few minutes. The originally planned place (which was
near perfect) turned out to be too expensive. The two
next ones we tried are already booked. There are still
some places outside the center, but this will require
organising transport as well, or a very long walk to
Anyway the plan *is to have a LSN*. Expect more news
in a week or so.
Meanwhile we've started making the detailed program.
Several people are involved in more than one activity
(papers, workshops, concerts, rehearsals) and taking
all this into account creates a rather complex puzzle.
For now I'll assume that all paper presenters will be
in Parma from thursday 16 april,11:00 to sunday 19
april,13:00. Sunday afternoon we'll have the workshop
reports, the traditional panel discussion and of
course the group picture.
If you present a paper and can't make it in time or
have to leave before the end of this period please
let me know ASAP.
For the early arrivals, on wednesday evening we'll
have the pre-conference pizza, and sunday evening
the very unofficial conference dinner.
The registration site should be up in a few days.
Looking forward to see you all in Parma,

I am promoting the development and manufacture of a new music keyboard
capable of playing all traditional and some new musical scales.
Descriptions of both can be found on my website at:
The new design has been placed in the public domain, and I am seeking
expressions of interest in persuading manufacturers to design and market
the new keyboards.
I believe that such instruments could initiate something of a musical
renaissance and a range of new musical styles. It would also be of great
value in training choirs to sing the pure, untempered intervals of
traditional music rather than the tempered intervals of standard
keyboards. I'm hoping for some assistance from the Linux Audio community
in moving this forward, and would be very pleased to hear from anyone
If one were to build a "kernel" to a digital audio workstation that was
itself a bare-bones LV2 host, could things like audio tracks, midi
tracks, and mixer channels and the like be built as LV2 plug-ins?
I've been thinking a lot about a comment made a while back about how
monolithic applications are very ill-suited to the open-source method of
development. So I got to thinking about how an operating system works
(at a high level; my meager coding skills are no matches for people
well-versed in operating systems) and began to ask some questions.
This "kernel" would have to handle things like audio routing, and
message passing between two "processes" (the LV2 plug-ins), and would
jockey the audio in and out of the plug-in graph. It would need to
support the GUI and event extensions, and probably a few others, at the
The hope might be that if such a kernel could be made, it might then be
a lot easier for many people to contribute the small pieces that would
make for a usable application. Please feel free to consider this
mindless brainstorming if you'd like.
Well, no response on the user list. Maybe someone here has an idea -
does the Tascam US-1641 work with Linux/ALSA? I'm assuming not and have
written a nice email to Tascam asking for a little information. I'm
assuming they're not going to be very helpful but it's worth a shot.

It's not on the downloads page because using it makes
sense only if you have the calibration for you microphone
- TetraProc requies around 40 paramters. This calibration
data can be derived only from IR measurements.
It is possible to use 'standard' values, given the
FR and polar pattern of the mic, but results will
not be very good.
Which microphone would you want to use ?
Would it be possible to measure it, if I
tell you how to do it ?

I've been toying recently with the X window test extension (which
allows the user to simulate input events) and I've decided to create a
bigger project that uses it. My project idea would be a unix daemon
that reads data from the sound card, gets the dominant frequency and
then reports a key corresponding to this data.
Unfortunately, I don't know the theory of spectrum analysis and I
don't think I could come up with a high-performance spectrum analyzer
in reasonable time.
So, my question is : do you know a good spectrum analyzer, preferably
written in C that I could modify ?
