Description:A host for LADSPA+LRDF, DSSI, LV2, VST2/3 and AU plugins plus GIG, SF2 and SFZ support.

Carla is an audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like automation of parameters via MIDI CC (and send output back as MIDI too) and full OSC control. Part of the KXStudio project.

Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2/3 and AU plugin formats, plus GIG, SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.

There are 3 types of engine processing:

  • Multi-client (JACK driver only). Every single plugin is exposed as a new JACK client. Audio and MIDI ports are registered as needed.
  • Single-client (JACK driver only). Same as Multi-client, except that all JACK ports belong to a single master client. This is needed when a setup doesn't support multi-client JACK apps, such as LADISH.
  • Rack. Plugins are processed in order, from top to bottom. Plugins with non-stereo audio channels are not supported, but a forced-stereo option is available for Mono ones.
