Carla mangrupikeun host audio profuler pribadi lengkep, sareng ngadukung pikeun seueur supir audio sareng format plugin.
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:
