      Xsynth-DSSI is a classic-analog (VCOs-VCF-VCA) style software

      synthesizer which operates as a plugin for the DSSI Soft Synth

      Interface.  DSSI is a plugin API for software instruments (soft

      synths) with user interfaces, permitting them to be hosted

      in-process by audio applications.
