QjackCtl is a simple Qt application to control the JACK sound server daemon, Written in C++ around the Qt framework for X11, most exclusively using Qt Designer.

Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features.
