Carla ndi wodziwika bwino wa ma modular audio plugin host, wothandizidwa ndi ma driver ambiri amawu ndi ma plugin formats.
Ili ndi zinthu zina zabwino monga kuwongolera mayendedwe, makina opangira magawo kudzera pa MIDI CC komanso kuwongolera kutali pa OSC.

Carla pakali pano amathandizira LADSPA (kuphatikiza LRDF), DSSI, LV2, VST2, VST3 ndi mawonekedwe a AU, kuphatikiza SF2 ndi SFZ thandizo la mafayilo.
Imagwiritsa ntchito JACK ngati dalaivala wanthawi zonse komanso wokonda nyimbo komanso imathandizira madalaivala amtundu ngati ALSA, DirectSound kapena CoreAudio.

Pali 4 mitundu ya processing injini:

• Makasitomala amodzi: (JACK driver yekha)
  Zofanana ndi Multi-client, kupatula kuti madoko onse a JACK ndi a kasitomala m'modzi.
  Izi ndizofunikira pamene kukhazikitsidwa sikugwirizana ndi mapulogalamu ambiri a JACK, monga LADISH.
• Makasitomala angapo: (JACK driver yekha)
  Pulagi iliyonse imodzi imawululidwa ngati kasitomala watsopano wa JACK. Madoko a audio ndi MIDI amalembetsedwa ngati pakufunika.
• Choyika:
  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.
