Ghostess is a a graphical DSSI host, based on jack-dssi-host, but capable of saving and restoring plugin configuration, as well as specifying MIDI channels and layering synths. ghostess includes three MIDI drivers: an ALSA sequencer MIDI driver, a (clumsy but functional) CoreMIDI driver (which allows ghostess to be used on Mac OS X), and a JACK MIDI driver for use with the MIDI transport in recent versions (>=0.102.27) of JACK. ghostess also comes with a universal DSSI GUI, which attempts to provide GUI services for any DSSI or LADSPA plugin, and may be used with any DSSI host.
