Does anyone know anything about this change in alsa:
warning: snd_pcm_sw_params_set_xfer_align is deprecated (declared
at /usr/include/alsa/pcm.h:1115)
I just wanted to check background before fixing the code.

Victor
The first milestone is reached and result is a tarball that brave souls
may want to download and try. It contains implementation of JACK
multiconfig functionality. JACK server settings can be saved as part of a
studio. Then, loading studio will cause JACK settings stored as part of
the studio to be restored.
Build will produce three operational components:
* ladishd - The daemon, a D-Bus service
* gladish - GTK GUI interface
* ladish_control - Command-line interface
In the tarball you will also find bundled suitable (latest and gratest)
flowcanvas and LADI Tools.

---------------------------------------------------------------------
LADI Session Handler or simply ladish is a session management system
for JACK applications on GNU/Linux. Its aim is to allow you to have
many different audio programs running at once, to save their setup,
close them down and then easily reload the setup at some other
time. ladish doesn't deal with any kind of audio or MIDI data itself;
it just runs programs, deals with saving/loading (arbitrary) data and
connects JACK ports together. It can also be used to move entire
sessions between computers, or post sessions on the Internet for
download.
ladish has GUI frontend, gladish, based on lpatchage (LADI Patchage)
and the ladish_control command line app for headless operation. LADI
Tools is set of apps that interface with ladish, JACK server and
a2jmidid
ladish requires D-Bus and JACK compiled with D-Bus support.
LADI Session Handler is rewrite of LASH.
Project goals:
* Save and restore sets of JACK (audio and MIDI) enabled
applications.
* Provide JACK clients with virtual hardware ports, so projects can
be transfered (or backups restored) between computers running
different hardware and backups.
* Don't require session handling library to be used. There is no need
of such library for restoring connections between JACK clients.
* Flow canvas based GUI. Positions of elements on the canvas are
saved/restored.
* Allow clients to use external storage to save its state. This
includes storing internal state to non-filesystem place like memory
of a hardware synth. This also includes storing client internal
state (client project data) in a way that is not directly bound to
ladish project.
* Import/export operations, as opposed to save/load. Save/load
operate in current system and may cause saving data outside of
project itself (external storage). Import/export uses/produces
"tarball" suitable for transferring session data over network to
other computer or storing it in a backup archive.
* Hierarchical or tag-based organization of projects.
* List of JACK applications. Applications are always started through
ladish to have restored runtime environment closer to one existed
before project save.
* Distributed studio - network connected computers. Netjack
configuration is part of the studio and thus is saved/restored.
* Collaborate with the X11 window manager so window properties like
window position, virtual desktop and screen (multimonitor) are
saved/restored.

Greetings,
Thank you for all your great feedback on the last two betas!
phasex-0.12.0-beta4 addresses all of the concerns brought up so far:
Velocity: Many of you have noticed that velocity and aftertouch
were completely unsupported. Now, velocity (with aftertouch) can be
mapped to directly to oscillators and LFOs (by setting the source),
used as a modulation source (adjust volume w/ AM or pitch w/ FM), or
mapped to the filter in the filter-lfo section.
GUI: Some of you mentioned that the colors were too dark with too
little contrast, so now there are four GTK theme options: Dark
(original purple background), Light (orange background), System (use
the system GTK theme), and Custom (choose any gtkrc file for your
theme). There have also been issues with getting phasex to fit on
small screens (usually netbooks). The knob images have been trimmed
down vertically (just blank pixels), and the padding between widgets
has been almost completely cut out. The font can be selected in the
preferences. Additionally, a true fullscreen mode has been added.
It is now possible to fit phasex into an 800x600 desktop.
Atom processors: Compiler optimization flags for the Intel Atom
processors have been added to the build system. Run './configure
--enable-arch=atom' to build for the Atom. To force 32- or 64-bit
builds, use 'atom32' or 'atom64'.
The rest is just small tweaks and bugfixes, such as fixing the
segfault on quit issue, fixing all the compiler warnings, minor
updates to the build system, new menu items, etc.
As I don't have access to a netbook right now, please let me know
how it works out with the Atom or other low-power CPU, or on any
machine with a screen smaller than 1024x768. Of course, feedback
from the rest of you is highly welcome, too ;-}

RPMS, or Fedora 8 RPMS.

Hallo,
This is a serious question for Linux Audio and in general multi media
applications developers.
I am in the program committee of the conference part of a Linux related
even in france (called Salon Linux), and we are discussing about the
2010 conference program.
I may be in the condition to have a Audio or multi media subject added,
but i can do that only if i have serious evidence of a user base or
a developer base in france. Most of the subjects are around enterprise
and industrial development.
The conference is strictly french-speaking, and the access is not
for free (even if the organisation is stricly on a volunteer base).
So, any French developers here, and any evidence of a French user base ?

I'm looking for some real time audio analysis software similar to the
melodic range spectrogram in sonic visualizer. Instead of visual output
though, I'm looking for midi output (this can be rough, i'm not going to be
generating audio from it, just trying to check if said notes were played).
I'm not sure if this is possible with clam, I've used it a little, but not
much.
The ideal solution will be multiplatform.
Thanks for any leads,
Nathanael
Hi everyone, I'm wondering what most linux audio developers think about
pyqt vs wxpy for writing audio app guis now that qt is gpl'd.
Specifically I'm interested in tightly controlling the timing of event
loop ( ie making some accurate external clock source like the csound
engine be the time boss ) and making decent faders widgets.
thanks!

Hey guys,
I had a performance the other day with a nicely underpowered PC (500 MHz).
One man show. Everything being run through JACK (guitar + vocals), using
sooperlooper, and jack rack plus some nice TAP effects (for vocals). Set
up for 10ms latencies.
Not long into it I looked at the computer and saw the hard drive light was
very bright. Great. My computer is running updatedb... _now_??? This is
bad. Since I was doing something slightly different... I really couldn't
afford any glitches. So, I was a little nervous.
But I trudged along. No crashes. No xruns. No clicks. No problems.
So, I'm taking a moment to say: Thanks, everybody.
Peace,
Gabriel

As I'm new to smart pointers and memory management in C++ I have a short
question on this topic.
I'm now using the following code to traverse the devices and their ports:
snd_seq_client_info_t *clientInfo = 0;
snd_seq_port_info_t *portInfo = 0;
snd_seq_client_info_malloc(&clientInfo);
snd_seq_port_info_malloc(&portInfo);
shared_ptr<snd_seq_client_info_t> clientInfoMemoryHandler(clientInfo,
snd_seq_client_info_free);
shared_ptr<snd_seq_port_info_t> portInfoMemoryHandler(portInfo,
snd_seq_port_info_free);
.
.
.
snd_seq_port_info_set_client( portInfo,
snd_seq_client_info_get_client(clientInfo ) );
snd_seq_port_info_set_port( portInfo, -1 );
while ( snd_seq_query_next_port( seq, portInfo ) >= 0 ) {
string portName = snd_seq_port_info_get_name( portInfo );
unsigned int capability = snd_seq_port_info_get_capability( portInfo );
.
.
.
Well the cleanUp methods are called at block-leaving.
I'm only a bit curious because after giving portInfo and clientInfo to
the shared_ptr for cleanup management I have to use them for all the
alsa queries.
But since I'm not using malloc and free in these queries everything is
ok, isn't it?
Thanks for your help!

Hi,
There are quite some people who like to have a better Lilypond MIDI
output. But they lack some people who are able and want to work on it.
That's why I send this message.
There are some improvements using the Articulate midi script:
http://www.nicta.com.au/people/chubbp/articulate
And suggestions are made to use Midge, Mididings or Midicomp in some
way, to improve it.
If you're interested to contribute, please mail to the Lilypond mailinglist:
http://lists.gnu.org/mailman/listinfo/lilypond-user
Thanks in advance,
\rooz
