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.
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 4 types of engine processing:
singleclient: (jack driver only) same as multiclient, except that all jack ports belong to a single master client. this is needed when a setup doesn't support multiclient jack apps, such as ladish. multiclient: (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 nonstereo audio channels are not supported, but a forcedstereo option is available for mono ones. patchbay: modular patchbay mode, just like in jack multiclient and many other modular applications. every plugin gets its own canvas group and ports allowing you to interconnect plugin audio and midi.
Alternativein is a new approach to finding good application.
