fluidsynth MIDI sound synthesiser front-end

 QSynth is a fluidsynth GUI front-end application written in C++ around the Qt
 toolkit. Eventually it may evolve into a softsynth management application
 allowing the user to control and manage a variety of command line softsynths
 but for the moment it wraps FluidSynth (http://www.fluidsynth.org).
 .
 FluidSynth is a command line software synthesiser based on the Soundfont
 specification.
