qjackctl - User interface for controlling JACK (Jack Audio Connection Kit)


qjackctl [options]


This manual page documents briefly the qjackctl command. This manual page was written for the Debian distribution because the original program does not have a manual page.

qjackctl is used for controlling the Jack Audio Connection Kit (JACK) and as a patchbay for ALSA MIDI devices. Qjackctl also has support for the JACK transport control protocol, so you can use it to start and stop the JACK transport. Once you start qjackctl, you get presented with a single GUI window, the buttons are self-explanatory and have tooltips.


This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, see the Info files.
-s, --start
Start JACK audio server immediately
-p, --preset=[label]

-a, --active-patchbay=[path]

-n, --server-name=[label]

-h, --help

-v, --version

Settings for the JACK system are stored in ~/.config/rncbc.org/QjackCtl.conf and optionally in ~/.jackdrc.
