Carla is a fully-featured audio plugin host, with support for many audio drivers and plugin formats.
It's open source and licensed under the GNU General Public License, version 2 or later.
This repository contains external plugins not part of the default Carla source code.
The reason for the split is to keep the main Carla code small, as these plugins are optional.
Note that these plugins are not usable as-is, they require Carla.
