The current iteration of the LV2 specification seems to have settled down, and there are a significant number of implementations now, so, assuming that there's no problems found with the current spec I propose to rename it as 1.0 in a few weeks time. Background - http://lv2plug.in/ LV2 is an upcoming standard for plugins and matching host applications. It's mainly targeted at audio processing and generation. LV2 is a successor to LADSPA, created to address the limitations of LADSPA which many hosts have outgrown. LV2 is not backwards compatible, but migration tools will be released once the specification is finalized. Implementations SLV2 - a library by Dave Robillard that makes it easy to add LV2 support to existing hosts, includes example code and documentation. tarball: http://download.drobilla.net/ , docs: http://drobilla.net/ doc/slv2/modules.html and sample code: http://drobilla.net/doc/slv2/ lv2_simple_jack_host.c LL plugins - lots of native LV2 plugins, an extension and a host that implements the extension, all written by Lars Luthman. http://ll- plugins.nongnu.org/ Zynjacku - a host for LV2 instruments by Nedko Arnaudov. http:// home.gna.org/zynjacku/ Ingen - a modular synth host that uses LV2, DSSI and LADSPA plugins as its modules.
