DSSI (Disposable Soft Synth Interface) is a plugin format (pronounced “dizzy). This is an extension to the LADSPA plugin format. DSSI plugins can have their own GUI's and were designed specifically with virtual instruments in mind. DSSI has been superseded by the LV2 plugin format. Supported hosts include Qtractor, Rosegarden and Carla.

LADSPA is a plugin format. It stands for Linux Audio Developers Simple Plugin API. LADSPA plugins come with no GUI's of their own, instead using their hosts generic GUI. Virtually every host supports LADSPA plugins. A popular collection of LADSPA plugins is the Caps suite of plugins.
