In this release:
* lv2rack does no longer require PHAT (it was not really using it even
in zynjacku-3 release)
* Support for out of process plugin UIs (the upcomming nekobee release
should use it)
* Don't crash when trying to load non-existing plugin (specified by
supplying plugin URI at commandline)
* Don't crash with some plugins (NULL extension_data)
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.

Hello Fons, I assume you forgot to CC linux-audio-dev.

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.

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
