I'm a university student. I'll book my flights right away, but I'd like to wait
booking the accommodation until I know more about this guest house.
Do they have wlan? :)

Hiho,
I am experiencing strange things with some code that uses the ALSA sequencer,
with the function
snd_seq_ev_schedule_real(evt, mQueue, 1, &time);
The timing of this is unreliable.
At times it goes as expected for a while, but then after some time large
delays (minutes, instead of the expected latency of 0.1 second) are
introduced.
Does anyone have any idea what the problem could be?
I have a code snippet below. In case anyone wants to try (the app is
SuperCollider, you need the latest svn).
I'm on a Debian kernel (2.6.24-1-amd64 #1 SMP Thu Mar 27 16:52:38 UTC 2008
x86_64 GNU/Linux), in case that is relevant.
sincerely,
Marije

In this release:
* Plugin presets (save/restore)
* Improved support for Calf plugins (various extensions needed by
development version)
* MIDI CC/Pitchwheel automation. Not yet available for custom
UIs. Works for float parameters only.
* Replace PHAT fansliders with bundled knobs. PyPhat is no longer
required.
* lv2dynparam host library is now optional. To enable support for
dynparam plugins (lv2zynadd) lv2dynparam1 version 2 is needed.
zynjacku is JACK based, GTK (2.x) host for LV2 synths. It has one JACK
MIDI input port (routed to all hosted synths) and one (two for stereo
synths) JACK audio output port per plugin. Such design provides
multi-timbral sound by running several synth plugins.
zynjacku is a nunchaku weapon for JACK audio synthesis. You have solid
parts for synthesis itself and you have flexible part that allows
synthesis to suit your needs.
lv2rack is a host for LV2 effect plugins.
You need slv2 library to compile zynjacku tarball.

lv2dynparam is LV2 extension for dynamic parameters.
The extension consists of a header describing the extension interface
and libraries, one for plugins and one for hosts, to expose
functionality in more usable, from programmer point of view, interface.
Changes since version 1:
* host library: API is refactored, the new API is NOT compatible with
the version 1 API
* host library: support for dynparam automation
* host library: support for dynparam parameter save/restore

Hello all,
We're pleased to announce the release of a new version of jackctlmmc
and a new Qt based graphical version called QJackMMC. The main page
including download links and documentation is here:
http://jackctlmmc.sourceforge.net/
In brief, QJackMMC is a Qt based program that can connect to a device
or program that emits Midi Machine Code (MMC) and allow it to drive
JACK transport, which in turn can control other programs. JackCtlMMC
is a slightly simpler command-line version of QJackMMC. You might need
such a tool if you have hard-disk recorders (HDRs) or other external
MIDI compliant devices that are capable of sending out MMC to keep
other devices in sync. You might have a multi-track recorder and you
want to be able to start, stop, or fast-forward JACK-based programs
such as Rosegarden, Hydrogen, and Ardour.
Enjoy,
-- Alex
hi guys!
today i felt a little bored and needed to do something to avoid
finishing my lac paper, so i brushed up the documentation about the wave
field synthesis live streaming project that i did for tu berlin last
year. if you need to kill some time and enjoy reading war stories with
linux audio, really loud music and infrared lasers in them, have a go at
http://stackingdwarves.net/public_stuff/event_documentation/wfs_live_transm…
best regards,

Hello all,
Many thanks to all who have responded to yesterday's
message ! There is still room for more, so start
writing the paper you always wanted to write, or
preparing the workshop you always wanted to do...
The paper deadline will be extended to the 29th
of this month.
Some practical info:
There are no formal calls for workshops or for
participating in the Linux Sound Night on the
conference website. For both just drop me line.
Regarding the LSN, I had a meeting with the
management of the Teatro Lenz this afternoon.
Lenz is very much one of the 'alternative'
cultural organisations in Parma, and would
be the natural place for something like the
LSN. Normally they would be organising a
festival in April and May, and the LSN would
fit in very well into it, allowing it to be
organised at minimal cost. But thanks to the
new cultural politics of the government guided
by Il Cavaliere (Berlusconi) Lenz won't have
any funding until September, and has to cancel
the festival. It's probably still possible to
use the location, and anyway we'll do whatever
is needed to get the LSN organised.
We will add some travel and visitor info to
the website early next week.
Earlier some of you expressed the desire for
developer meetings, brainstorms or working
sessions. I'd ask any specific groups who
want to meet in Parma to get organised and
keep me informed.
Finally, it's *freezing* cold here right now,
but I promise more enjoyable meteorological
conditions in April !
Ciao,
