Carla ~ Cross-platform Plugin Host


Carla is a fully-featured modular audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like transport control, automation of parameters via MIDI CC and remote control over OSC.

Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2, VST3 and AU plugin formats, plus 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 4 types of engine processing:

  • 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.
  • Multi-client: (JACK driver only)
    Every single plugin is exposed as a new JACK client. Audio and MIDI ports are registered as needed.
  • 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.
  • Patchbay:
    Modular patchbay mode, just like in JACK Multi-client and many other modular applications.
    Every plugin gets its own canvas group and ports allowing you to interconnect plugin audio and MIDI.

JACK ~ Audio Connection Kit


Have you ever wanted to take the audio output of one piece of software and send it to another? How about taking the output of that same program and send it to two others, then record the result in the first program? Or maybe you’re a programmer who writes real-time audio and music applications and who is looking for a cross-platform API that enables not only device sharing but also inter-application audio routing, and is incredibly easy to learn and use? If so, JACK may be what you’ve been looking for.

JACK Rack is an effects “rack” for the JACK low latency audio API. The rack can be filled with LADSPA effects plugins and can be controlled using the ALSA sequencer. It’s phat; it turns your computer into an effects box.
