The LV2 host Elven that comes with this software package is written for revision 2 of the LV2 specification and is NOT compatible with revisions 3 and later. It may work, it may break subtly or it may give your computer the swine flu. Use at your own peril.
This is the home of the software package ll-plugins, which is a collection of LV2 plugins. LV2 is an open DSP plugin architecture designed primarily for software running on GNU/Linux.
Everything here is of course free software released under the GNU General Public License.
If you want to see what's going on you can get the latest (buggy, unfinished, not working) code from Git using this command:
git clone git://git.sv.gnu.org/ll-plugins.git
Everything in the Git repository is under development - do not expect any of it to work in the same way as it used to, or at all.
