[ANN] lv2vocoder plugin version 1 released (Happy robots use Linux and LV2!)

by Nedko Arnaudov

Perhaps you don't know what a vocoder is, but I'm sure you have heard one before. Vocoders are often used to add a robotic effect to vocals in music. Project homepage: https://gna.org/projects/lv2vocoder Get tarball from here: https://gna.org/files/?group=lv2vocoder This code is based on version 0.3 of LADSPA plugin created by Josh Green. LADSPA plugin created by Josh Green is basically an adaption of Achim Settelmeier's Vocoder program to LADSPA. Achim Settelmeier's Vocoder programs and Josh Green's LADSPA plugin, can be found at: http://www.sirlab.de/linux/ Happy robots use Linux and LV2! -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[ANN] zynadd plugin version 1

by Nedko Arnaudov

The zyn project main goal is to extract synth engines from ZynAddSubFX and pack them in LV2 plugin format. Resulting plugin(s) are heavily based on work made by Nasca Octavian Paul. Project goals: * Port ZynAddSubFX synth engines to LV2 * Fix some inherit issues preventing hard-realtime mode of operation, causing clicks sometimes (memory allocation/sleep in audio process context) * Make synth engines reusable in source form * Make all synth engines parameters controlable on the fly (as opposed to original "parameter change takes effect on next note on" strategy) Currently only zynadd (ADDsynth) is ported. Not all parameters are exposed yet. Nevertheless plugin produces sound/noise and has enough parameters exposed to tweak sound generation at great extent. You need lv2dynparam plugin library to compile the plugin.

[ANN] zynjacku version 1 released

by Nedko Arnaudov

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. You need slv2 library and lv2dynparam host library to compile zynjacku.

[ANN] first versions of lv2dynparam extension and helper libraries for it

by Nedko Arnaudov

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.

[ANN] new version of ssg (Simple Sine Generator)

by Nedko Arnaudov

New version of Simple Sine Generator is available. It now requires lv2core. Simple Sine Generator is very simple instrument/generator plugin with midi in and audio out ports. It expected to be useful for testing LV2 hosts and as base for writing your own plugins. It is written in plain C. http://nedko.arnaudov.name/soft/ssg/ http://nedko.arnaudov.name/soft/ssg/ssg-20080109.tar.bz2 http://nedko.arnaudov.name/soft/ssg/ssg-20080109.tar.bz2.sig -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

SLV2 0.4.2 Released

by Dave Robillard

Hi all, SLV2 is a C library to make the use of LV2 plugins as simple as possible for host applications. Unlike LADSPA, LV2 is (more or less) designed with the assumption that hosts will use a library to discover/load/use plugins. SLV2 is one such library, which does the Right Thing with as little burden on host authors as possible. This release corresponds to the new stable LV2 release, Revision 1. More information, API documentation, and downloads can be found here: http://drobilla.net/software/slv2/ Enjoy, - Dave Robillard (aka drobilla)

[ANN] lv2-c++-tools 0.1.666 - alpha testers wanted

by Lars Luthman

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. Get the whole thing here: http://download.savannah.nongnu.org/releases/ll-plugins/lv2-c++-tools-0.1.6… 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! --ll

LV2 Released

by Dave Robillard

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: http://lv2plug.in/ Happy hacking, ~ The LV2 team

NtEd is the real WYSIWYG music score

by Roque Morel

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 ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/MandrivaLinux/devel/cooker/x86_64/media/contrib/release/nted-0.13.0-1mdv2008.1.x86_64.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. Roque Morel
