lv2-c++-tools is a package containing a couple of libraries and programs
that may come in handy when writing LV2 plugins. These tools are
* libpaq - a basic RDF/Turtle parsing and querying library. You
probably don't want to use it, it's rather big and inefficient.
It's just here because it's used by...
* lv2peg - a program that reads RDF data files for LV2 plugins and
generates C header files with enums and static data for the port
indices/symbols/min/max/default values/common hints etc. Can be
useful to embed in your build system while you're hacking on a
plugin so you don't have to keep the RDF data and the code in sync
manually.
* liblv2-plugin - a library of C++ classes that you can inherit from
to create LV2 plugins. The base classes take care of all the
low-level LV2 interfacing with the host so you can implement your
plugin by overriding a couple of member functions.
* liblv2-gui - same thing for LV2 plugin GUIs.
Both these libraries are tiny static libraries that you link into your
plugins so using them will not add any runtime dependencies.
The build dependencies are the Boost headers (more particularly the
Boost.Spirit parsing framework), for libpaq, and gtkmm >= 2.8.8, for
liblv2-gui.

Once you have installed it you can read the tutorial at
http://ll-plugins.nongnu.org/lv2pftci/
and the API reference at
http://ll-plugins.nongnu.org/dox/lv2-c++-tools/0.1.666/
There may be typos, redundancies or even (gasp!) bugs in the code and
documentation, but that's what alpha testing is for!

Announcing the first stable release of the LV2 specification.
LV2 is a simple but extensible successor of LADSPA, intended to address
the limitations of LADSPA which many applications have outgrown. By
creating LV2 "extensions" (which can be done independently), virtually
any feature is possible for LV2 plugins and hosts.
This release (revision 1) has been in active use by many projects for
several months, including several extensions for advanced features
beyond the capabilities of LADSPA or DSSI.
Strong long-term compatibility is a primary goal of LV2: all future
revisions of LV2 will remain backwards compatible with previous
revisions.
All the components of the "core" LV2 specification are packaged here:
http://lv2plug.in/spec/lv2core-1.tar.gz
Distributions are encouraged to include this package.
More information, downloads, and links to LV2-using projects can be
found at:

Happy hacking,

Hi. My name is Roque Morel, I`m a musician, I not hacker, geek,
programmer etc and I wanna talk about NtEd, in my opinion, the real
WYSIWYG music score for Linuxes.
NtEd is the easiest music score I`d saw. Installation, specially for me,
is not complicated, just I`m a violoncello player.
Only three steps: ./configure, make, make install and it`s ready to use.
Rare dependencies and libraries does not need it. Where another ones
failed on my favor distro, NtEd got no any trouble.
Commands are very easy too and it works very well with Timidity or
QJackctl+QSynth.
It supports tuplets and others, up to 4 voices per staff, 5 lyrics
lines, three clefs, exports to GS and MIDI.
Very important things?
It`s a real page view music score for Linux, it`s easy for musicians, it
is not a too much MB program, it`s nice to work and the more important
point in music: it`s a What You See Is What You Get music score and is
stable.
Necessary things?
Slurs, bow signals for strings instruments, more clefs and other musical
signs.
For Mandriva`s users as me, there are some packages in cooker
repositories I asked by bugzilla
ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/MandrivaLinux/devel/cooker/cooker/media/contrib/release/nted-0.13.0-1mdv2008.1.i586.rpm

Enjoy it and I`m sorry about my English language, it`s so poor... I`m
from Argentina and I speak only a few words.

Can't hold it anymore... :)
Since its primordial presentation on the LAC2007@TU-Berlin, almost one
year ago, I guess it's finally ready for an official public release. So
here it goes.
Qtractor development has been going stealthy but has been matured
nicely. Still alpha however, but quite practical nevertheless. Or so I
believe. Yes, things might get bumpy, faster or slower though, we never
know in advance. And quite frankly I don't give a damn whether how it
might progress from now. But it will progress, that's what I shall write
here engraved ;) Trust me.
Qtractor has been my hobby, kind of personal purpose in life and should
stay in that status for quite some time. You probably have noticed
there's too many buts in this discourse of mine, and guess what? there
follows some more for your pleasant delight.
As long as all its ecosystem bears sustainability; no hidden thoughts;
it's all about JACK, ALSA and ultimately Linux that I'm counting on.
I've made myself ascertain: I will make no effort, whatsoever, in doing
any kind of cross-platform dance. Although it seem feasible, just don't
expect that kind of behavior from this side of the party. I'm not
obliged to. I'm happy now with what I've got and to what has been
achieve in this recent years. Linux is my home and you better get it
right, I'm comfortable with it.
It could be seen as my "masterpiece", although you might find I'm no
master at all. Take it as my pet project, because, in fact, it is just
that, really! If you feel minimally interested, you might want to come
along and be welcome. I'll cherish you, that's what friends are. Willing
to share the journey, and follow the turns. No commitments, just fun!
Now, after that bunch of BS, let's get the facts straight, right behind
the thoughts:
Qtractor 0.1.0 (frivolous debutante) has been released!
Good grief. As always, everyone is welcome to grab the source and also
some selected binary packages, available from the official project site:
http://qtractor.sourceforge.nethttp://sourceforge.net/projects/qtractor
Direct link for the source tarball download:
http://downloads.sourceforge.net/qtractor/qtractor-0.1.0.tar.gz
For the clueless, a refurbished whitepaper is also available:
http://downloads.sourceforge.net/qtractor/qtractor-0.1.0-whitepaper.pdf
Also of note is this (strong) invitation to follow my personal blurbs,
right from the upstream blog and forum site:
http://www.rncbc.org
Here follows the change-log. as recorded since that one last previous
pre-release, which was tagged as 0.0.9.778 (adolescence prime) on the
late year:
- Audio clip time-stretching makes its debut, with code adapted and
refactored from the SoundTouch library, under the (L)GPL umbrella.
- New "Options.../Audio/Playback/Quick seek time-stretching" global
option, providing a quick seek mode (hierarchical search) while
doing all audio buffer time-stretching.
- Changing session tempo will automatically apply the corresponding
time-stretch percent factor to all in-place audio clips. Audio
clip dialog also includes a new time-stretch property setting.
- Tempo changes are now affecting clip offsets correctly, keeping
the clip offset constant in time units (ticks), as are clip start
and length properties already.
- Mixer splitter sizes are now properly saved/restored when hidden.
- Extended multi-selection is now featured on the files widget; all
drag and drop functionality has been almost completely rewritten.
- SSE optimization is now enabled where available (via configure).
- Options for having separate dedicated ports for the audition/pre-
listening player output, audio metronome output, MIDI control
input/output and MIDI metronome output, are now in place.
- A brand new subtle option sneaks in, affecting the drag-and-drop
of the main track-view: View/Options.../Drop multiple audio files
into the same track, whether to drop multiple external files into
new or existing track as concatenated audio clips.
- The audio metronome makes its debut as an alternative to the MIDI
existing one; parameters include bar and beat audio sample files,
accessible from the View/Options.../Audio/Metronome dialog.
- Files widget action refactorization; the files context menu gets
its due item icons and a new menu item for direct audio player
accessibility.
- MIDI time resolution changes (ppqn, ticks per beat) now tries to
keep all session MIDI clip times unchanged as far as possible.
- MIDI channel volume and panning control change events, CC#7 and
CC#10 respectively, are now rendered unfiltered on playback .
- First rendition of the long due implementation of an audition or
pre-listening audio player is now in place; the files window got
this new play/stop control button on its lower-right corner.
- Actual instrument definition note (keys) and controller names are
now in effect on the MIDI editor, whenever applicable.
- Fixed instrument bank selection method, "Bank MSB" (2), which was
broken enough to never send the correct bank number.
- Mouse-wheel horizontal scrolling is now accessible on every view,
while pressing a modifier key (Shift or Ctrl).
- New auto-backward transport option: when enabled the playhead will
be reset backward automatically whenever transport stops playing.
- A suicide-crash has been fixed while invoking the bus dialog from
the respective mixer bus strip context menu.
- Master (default) buses are always set to Duplex mode, being now
an enforced update policy while on the Buses dialog.
- A stupid lockup bug (infinite loop) was spotted on the track bus
assignment method and squashed (thanks, lexridge).
- New keyboard shortcuts for toggling the Connections tool (F8) and
the mighty Mixer tool (F9) windows.
- Avoid showing a context menu while right-clicking on time rulers.
- Audio clip waveform drawing gets additional closing points.
- It is now possible to change the length/size of a clip by dragging
its left or right edges, while in the main track-view. Shift+drag
will also time-stretch to the resulting audio clip length.
- Another off-by-one mistake was corrected, which was causing audio
clips to go out-of-sync on loop turnover boundary; also changed
the loop turnaround strategy, now honoring already cached periods.
- A race-condition has been mitigated in the audio-buffer thread,
that was exposed and lead to sudden application freezing upon
changing some composite audio clip commands.
- Take absolute audio peak values only, making peak files a little
bit shorter and hopefully faster to load and draw as waveforms.
Ah, never's too late to wish you all a Happy New Year!
Cheers && Enjoy

Pre-release of Wav Composer Not Toilet 1.26
wcnt is a not-real-time commandline text-file-based modular
synth/sequencer/sampler for GNU/Linux to generate WAV audio files.
Download from:
https://sourceforge.net/project/showfiles.php?group_id=76646&package_id=256…
Website:
http://wcnt.sourceforge.net
--------------------------------------------------------------------------
This is the second release building up to wcnt-1.26
Since wcnt-1.25.5, the program has undergone many important changes.
* libsndfile: the audio file IO lib from mega-nerd.com allows wcnt
to read and write *WAV* audio in other data formats besides 16bit
pcm. Consequently, all 16bit 'audio' inputs and outputs have been
removed. *** Make sure you have it installed *** :)
* LADSPA: a number of modules (9) have been created to use a select
few LADSPA plugins. These provide much better filters, reverb,
limiting, and compression. More might be added in future.
* orbit module: impliments three orbit fractals which iterate upon
a trigger, and the output of which is scaled (via an iteration
test) within the -1.0 to +1.0 range.
* adsr_scaler data object: allows indivdual sections of previously
defined adsr modules to be scaled on the time axis. it's quick
and easy.
* improved command line option handling: help describing the command
line options. several new options such as --dont-run and --no-title.
module help now lists the modules sorted into three alphabetical
collumns to make life easier.
* many memory leaks plugged, and numerous operational bugs squashed.
* no more -ffast_math compiler optimizations causing dodgy calculations.
* removed sine_wave and tri_wave modules altogether.
* wave module: a new easy-to-use module for quickly generating sine,
triangle, and sawtooth waveforms and a number of variations of these
outputting in the 0.0 to +1.0 range (instead of -1.0 to +1.0).
* wave_phase module: comes close to the old sine_wave and triangle_wave
implimentations. seperate phase trigger and phase_step inputs, and
seperate phase_step input for a shaping waveform. improved algorythm
means it's more likely to do what it's meant to :). new parameter to
invert every other phase (or every other partial phase etc), combined
with shaping (ie multiplication of two waveforms) allows a greater
variety of waveforms to be created.
* dc_filter and rms modules: no longer do their calculations in such an
extremely deffective manner.
* deg_size type inputs and outputs renamed to the far more sensible
phase_step type.
* constant_freq and constant_note: two new constant modules which
output translations of their parameter, so they're independant of
the sample rate unlike doing the same thing with the constant module.
* balance module: this is the modifier module renamed to show what it
actually does: balance two signals.
* modifier module: does something much more interesting than balance
two signals - ie combining two waveforms to create a third.
* many code changes and improvments.
--------------------------------------------------------------------------
***** Please note the online help at wcnt.sf.net is now out of date.
I've begun working on inline help, the beginnings of which are included
as a number of text files. The text files provide short descriptions and
guidlines on the usages of individual modules.
***** All your old .wc files will now be broken with this version. Sorry
- things change as I slowly learn.

Will there be a list of nearby hotels posted on lac.linuxaudio.org ?
I'd like to be able to book in advance.
Cheers,
